Biosynthesis of Aromatic Amino Acids






Gelatin Hydrolysis Test

Objective:
            To determine the ability of bacteria that produces extracellular hydrolytic enzyme Gelatianse that degrade gelatin.
Principle:
            Gelatin is a protein obtained from animal protein collagen, a major component of connective tissues and tendons of humans and animals. It is an incomplete protein with lacking of essential amino acid tryptophan. Gelatin maintains its gel properties below 25 ͦ C and exists as a solid in nature. At temperature above 25 ͦ C, gelatin is a liquid.

            Some microorganisms capable of producing proteolytic extracellular enzyme gelatinase which hydrolysis this gelatin into amino acids. After this degradation, it will not return to gel characteristics even at very low temperature 4 ͦ C.

Materials required:
24 Hours old bacterial cultures (Bacillus sp. and E.coli )
Nutrient gelatin
 Procedure:
-Prepare sterilized nutrient gelatin in test tubes and allow to solidify.
-Inoculate the organisms into gelatin tubes by stabbing
-Incubate the tubes at 37 ͦ C for 24 hours (May require upto 14 days to liquefy the gelatin.
-Following incubation, place the tubes in refrigerator at 4 ͦ C for 30 min.
-Observe the liquefaction (Liquid formation) in tubes
  (If bottom is resolidifies, slant the tubes and notice the surface of the medium is liquid or not)

Result:
Bacillus sp., is Gelatin hydrolysis positive (Gelatin liquefied)
E.coli is Gelatin hydrolysis positive (non liquefied)













Interpretation:
Bacillus sp. shows positive result as the medium remained liquefied after refrigeration. This result indicates that the organism produce gelatinase enzyme. E.coli give negative result as the medium remains solid after refrigeration.
           
Gelatin Hydrolysis Positive Organisms:
Bacillus sp.
Clostridium perfringens
Proteus vulgaris
Staphylococcus aureus

Gelatin Hydrolysis Negative Organisms:
E.coli
Staphylococcus epidermidis
Enterobacter aerogenes


Nutrient Gelatin Composition:

Catalase Test


Objective:

            To determine the ability of bacteria that produces Catalase enzyme which degrades the hydrogen peroxide.

 Principle:
           
            The enzyme Catalase produced by several bacteria, which is breakdown the hydrogen peroxide and releases oxygen and water. Organisms are producing O2 products like superoxide and hydrogen peroxide during cell respiration, accumulation of hydrogen peroxide and superoxide leads to the destruction of cell constituents and death of the organisms. The superoxide dismutase enzyme, which catalyzes the destruction of toxic superoxide and Catalase enzyme which catalyzes the degradation of hydrogen peroxide. Obligate aerobes and certain anaerobes contain these types of enzymes, but most of the strict anaerobes lack of above enzymes and therefore they cannot tolerate oxygen.
              


Catalase production can be determined by addition of the substrate H2O2 on bacterial culture, if bacteria produce catalase enzyme the above said chemical reactions liberate oxygen gas and producing bubbles, it indicates the presence of catalase. This test also useful for differentiate the morphological similar organisms like Enterococcus (Catalse negative) and Staphylococcus (Catalase positive).
           
Materials required:

- 24 Hours old bacterial cultures (Staphylococcus  and Streptococcus )
- 3 % Hydrogen Peroxide (H2O2)
- Glass slide/ test tube
- Inoculation loop/ glass rod
Procedure:

1.      Slide Method:
   - Pure growth of the organisms will transfer the clean slide by using inoculation loop or glass rod.
  -   Immediately add a drop of 3% hydrogen peroxide on bacterial culture.
    -  Observe the bubble formation (Effervescence).

2. Tube Test:
-   Take one ml of 3 % hydrogen peroxide in test tube.
-   Small amount of bacterial culture introduce into the solution
-   Immediately observe the effervescence.

Result:
 Staphylococcus  is shows catalase positive with bubble formation
 Streptococcus is catalase negative with no bubble formation

                                                                            a)
                                                    
                                                                  b)







              



Interpretation:
           In aerobic organisms, during aerobic respiration, oxygen serves as hydrogen acceptor and hydrogen peroxide is formed in the cell. High concentration of H2Ois formed which is toxic to cell.  Staphylococcus posses the catalase enzyme that converts hydrogen peroxide into oxygen and water. Streptococcus doesn’t releases catalase enzyme and this organism doesn’t convert
H2O2 into oxygen.

Catalase Positive Organisms:
Staphylococcus,           
E.coli,           
Pseudomonas aeroginosa,         
Klebsiella,
Salmonella,         
 Shiegella,
Proteus,
 Enterobacter,
 Citrobacter.

Catalase Negative Organisms:
Streptococcus
Most of the anaerobic organisms

Food Microbiology;Quality Standard : BS 5750

British Standard 5750:

A British Standard for Quality Assurance (BS 5750 'Quality Systems') was published in 1979. It contained a description of the controls which it prescribed were required to be instituted in order for a supplier to claim that it was a 'Quality Assured' Organisation.

In the same way as with the registration of products to a particular standard, an organisation could not be accredited to BS 5750 unless it had been inspected (and formally accredited) by an independent authority (such as the British Standards Institute) against the standard. In contrast to the Kite Mark (which is a method of product certification), BS 5750 is a form of company certification.

The standard specifies all those 'elements' of the management system which are seen to be critical to the quality of the final product and describes how these elements are to be controlled. 3 Although its initial adoption by industry was quite slow, a number of organisations have now implemented Quality Systems commensurate with the requirements of BS 5750, although its predominance in the engineering sector remains. In fact, BS 5750 has been increasingly criticised for its continued focus on the engineering / manufacturing environments - which a quick glance at the index of the standard will show.

In more recent years, in particular, a number of non-engineering and service sector organisations have recognised that the philosophy of Quality assurance is in fact applicable to every organisation and have sought a more broadly based guideline or standard. In an effort to accommodate the views of these other industry sectors, a number of QAS (Quality Assurance Schedules) have been produced to augment / amplify the standard.

Schedule no. 8 for example, is written specifically for the Service Sector industries and contains some additional requirements and guidance on the interpretation of the standard's requirements for these organisations. In 1987 the entire standard was revised and republished and its format was significantly amended.

The text is now identical with that of its equivalent International and European Standards - ISO 9000 and EN 29000. BS 5750 is due for another major renewal in 1996 and there is currently some interesting discussion underway as to its most desirable format and scope. It should be noted that the Nuclear Industry has for some time had its own Quality System Standard. In the UK this is BS 5882 ('Specification for a Total Quality Assurance Programme for Nuclear Power Plants'), which is similar in philosophy to BS 5750.

Oxidase Test

Objective:

  •    To demonstrate the ability of bacteria that produces the enzyme cytochrome oxidase.
  •   To distinguish the bacterial groups based on oxidase activity.

Principle:

            In aerobic respiration, oxidase enzyme plays a vital role in operation of electron transport chain. Cytochrome oxidase transfers the electrons from donor to molecular oxygen, during the oxidation of reduced cytochrome c to form water (or) hydrogen peroxide and oxidized cytochrome c.
            The ability of bacteria produce cytochrome oxidase enzyme can be determined by using oxidase disc impregnated with N, N, N΄, N΄ tetramethyl p-phenylene diamine dihydrochloride (TMPD) reagent. This reducing dye become oxidized and turns into deep purple color from colorless by oxidase enzyme, the colored end product is called indophenol. Pseudomonas is the only species which gives positive reaction in enterobacteriaceae family.

Materials required:

- Bacterial cultures (Pseudomonas sp., and E.coli )
- Oxidase disc (Readymade)
(Preparation of Reagent:  1% solution of N, N, N΄, N΄ tetramethyl p-phenylene diamine dihydrochloride (5g in 5ml in distilled water).  Disc preparation: Soak the sterile filter paper disc in few drops of reagents)

Procedure :
1.      Pick the 24 hours old bacterial cultures by platinum loop/plastic loop and smear over the oxidase    disc.
2.      After 10 min. observe the color change on disc.

Observation :
-   Deep purple color change of the disc with   Pseudomonas sp.,
-   No color change in the disc with E.coli
      
Result :
Pseudomonas sp., gives oxidase positive
- E.coli shows oxidase negative.


                             


       
Interpretation:
            Pseudomonas sp., gives positive result because it oxidizes the reagent N, N, N΄, N΄ tetramethyl p-phenylene diamine dihydrochloride and turns into deep purple color by oxidase enzyme. The purple colored compound known as indophenol. E.coli gives negative reaction because it doesn’t produces oxidase enzyme.

Oxidase positive organisms:

Pseudomonas sp., Vivrio chlorae, Nisseriae  sp., Camphylobacter sp., Alcalgenes sp., and Helicobacter sp.,

Precautions:
1.      The regent is to be prepared fresh.
2.      Nichrome wire is not to be used take culture. Trace of iron gives false positive result
3.      Should not take culture from selective medium
4.      Observe the result within the prescribed time.

Casein Hydrolysis Test

Objective:

 To demonstrate the ability of certain microorganisms to produce extracellular enzymes,    capable of degrading the milk protein casein.

Principle:
           
            Casein is the principle protein of the milk. It is the large polymer and colloidal suspension which gives opaque whiteness to the milk.   Casein is too large to enter into the bacterial cell membrane. In order to utilize the casein, bacterial cells secrete proteolytic exoenzymes (caseinase and peptidase) outside of the cell that break down the protein into amino acids.  The amino acids can then be used by cells after crossing the cell membrane via transport proteins. Casein hydrolysis is tested by growing an organism on a skim milk agar plate (providing nutrients and the casein) and then checking the plates for hydrolysis.  Plates without any hydrolysis will be white from the casein, whereas those exhibiting hydrolysis will have zones of clearing around the growth.

Materials required:
 - Bacterial culture (Bacillus sp.,)
- Skim milk agar

Procedure:
1.      Inoculate the bacterial cultures on skim milk agar medium by streaking. 
2.      The plates are incubating at 37° C for 24 hrs. 
3.      Following incubation, observe the zone of hydrolysis around the line of growth.

Observation:
-   Zone of clearance around the colonies of Bacillus sp.,

      
Result : 
Bacillus sp., shows positive result in casein hydrolysis  

       
Interpretation:
            A positive reaction is indicate by the zone of hydrolysis around the colonies of Bacillus sp. This is due to breakdown of casein by caseinase and other enzymes. In negative reaction indicates absence of enzymes showing no zone of hydrolyzing.


Casein hydrolyzing organisms:

Bacillus subtilis., Pseudomonas sp.,









Skim Milk Agar Composition:

Skim milk powder    100 g
Peptone    5g
Agar       15 g

Distilled water 1000 ml

Starch Hydrolysis Test

Objective:

-To determine  the ability of certain microorganisms to produce extracellular enzyme  amylase that breaking down starch.

-To identify the starch hydrolyzing bacteria.


Principle:
           
            Starch is a high molecular weight branching polymer. Starch as such cannot be transported to the bacterial cell for energy generation due to its high molecular weight. Therefore starch hydrolyzing exoenzymes are released into the surrounding media which can degrade starch to its glucose monomeric units. These soluble low molecular weight glucose can pass into the cell can be utilized energy generation by microbes.

                                     

Starch agar is nutritive medium with starch. The presence and absence of starch in the medium can be detected by addition of iodine, as iodine reacts with starch to import blue black color.


Materials required:
Bacterial cultures (Bacillus sp., and  E.coli)
Starch agar medium

Procedure :
1.      Inoculate the bacterial cultures on starch agar medium by streaking.
2.      The plates are incubating at 37° C for 24 hrs.
3.      Following incubation, pour the iodine solution on medium and observe the clear zone around the area of growth.

Observation:
- Clear zone around the line of growth of Bacillus sp., 
 In E.coli Plate turns completely blue black color, without zone formation.

Result :
-  Bacillus sp  : Starch hydrolysis positive
- E. coli : Starch hydrolysis negative

Interpretation:
           
            The clear zone of hydrolysis around Bacillus sp., when flooded with iodine solution, indicates that organism produces extra cellular amylase enzyme that hydrolyse starch in the media. E.coli showed negative result  as it did not produce amaylase. Thus could not hydrolyse starch and hence when iodine added it produced blue black color.

  
Starch Hydrolysing organisms:

Bacillus subtilis, Bacillus megatarium

 
Clear zone around the the Bacillus sp.,
(Starch hydrolyzing bacteria)

Below the first plate is positive and the second one is negative

Meat Food Products Order

Regulation for the production of meat products are covered by the Meat Food Products Order, 1973.

The Directorate of Marketing and Inspection at the ministry of Agriculture is the regulatory for the order, which is equally applicable to domestic processors and importers of meat products. The order -

1.  Species sanitation and hygiene requirements for slaughter houses and manufacture of meat products.
2.  It also contains packing, marking and labeling provisions for containers of meat products.

3.  Defines the permissible quantity of heavy metals, preservatives and insecticide residues in meat products.

Ministry of Food processing industries administers Meat Food Products order (MFPO), 1973 which ensure quality and hygienic production of meat food products including fish products

Meat food products are regulated through licensing under MFPO, 1973. Provision of MFPO requires on four stages of inspection by qualified veterinary doctors for hygienic production of meat products

       Ante-mortem inspection of animals before slaughter

       post-mortem inspection of animals after slaughter

       in-process physical inspection of meat, sanitary and hygienic processing in licensed unit

       sampling and analysis of meat products in meat testing laboratories for various parameters
Consumer needs to know that processed meat food products may contain safe and permitted  preservatives  and  additives  as   indicate   in  the  label.   He  needs   to     check
„ingredients‟, „expiry‟ and „best before‟ date and insist on cash memo while purchasing. Consumer needs to understand that if the meat food product is contaminated, adulterated or sub- adulterated, legal remedies are available for penalizing the offenders. It is illegal to transport meat unless it has been prepared and processed according to the provisions of the order and carries the mark of inspection.

It provides means to:

·         Detect and destroy meat of diseased animals

·         Ensure that the preparation and handling of meat and meat products be conducted in a clean and sanitary manner


·         Prevent the use of harmful substances in meat foods

·         See that every cut of meat is inspected before sale to ensure its wholesomeness

The order also lays down rules and conditions for procedure to be adopted for the selection of disease- free animal, slaughter house practices for further treatment of the meat so as to maintain the meat in a wholesome manner and devoid of pathogens.

Essential Commodities Act, 1955

The main objective of this act is to supply of essential commodities to the public by proper regulation, prevention of black marketing and making it available to the public at reasonable price. This act has been amended upto 24.12.1986 and is under the Legislative Department, Ministry of Law, Justice and Company Affairs.

The essential commodities mean any of the following classes of commodities:

· Cattle fodder including oil cakes and other concentrates

· Coal including coke and other derivatives

· Component parts and accessories of automobiles

· Cotton and woolen textiles

· drugs

· Food stuffs including edible oilseeds and oils

· Iron and steel including manufactured products of iron and steel

· Paper including newsprint, paper board and straw board

· Petroleum and petroleum products

· Raw cotton whether ginned or un-ginned and cotton seed

· Raw jute

· Any other class of commodity which the Central Government by notified order declares to be essential commodity.

Salient features of this Act are as follows:


(1)  In its endeavor to ensure availability of essential commodities to the consumers and to protect them from exploitation by unscrupulous traders, the Government of India has armed itself with the Essential Commodities Act, 1955 and the Prevention of Black marketing and Maintenance of Supplies of Essential Commodities Act, 1980 (PBM Act,1980)


(2)  The Essential Commodities Act, 1955 provides for the regulation and control of production, distribution and pricing of commodities which are declared as essential for maintaining or increasing supplies or for securing their equitable distribution and availability at fair prices. The enforcement/ implementation of the provisions of the Essential Commodities Act, 1955 lies with the State Governments and UT Administrations.

(3)  The list of essential commodities has been reviewed from time to time with reference to the production and supply of these commodities and in the light of economic  liberalization in consultation with the concerned Ministries / Departments administering these commodities. The number of essential commodities has been brought down to 7 at present through such periodic reviews. The Central Government have also been empowered to add, remove and modify any essential commodity in the public interest in consultation with the State Governments. However, addition / modification of any essential commodity will depend on when there is a scarcity or non-availability of the commodity in a situation like war, natural calamities, disruption or threat of disruption of supply of such essential commodities, which cannot be tackled through normal trade channels requiring Central Government‟s intervention under the said Act.

(4)  To enable the State Governments/UT Administrations to continue to take effective action for undertaking de-hoarding operations under the Essential Commodities Act, 1955, it was also decided with the approval of the competent authority to impose restrictions by keeping i respect of edible  oils,  edible  oilseeds,  rice,  paddy  and  sugar. These  Orders have been extended from time to time.

(5)  The Prevention of Black marketing and Maintenance of Supplies of Essential Commodities Act, 1980 is being implemented by the State Governments/UT Administrations for the prevention of unethical trade practices like hoarding and black- marketing etc. The Act empowers the Central and State Governments to detain persons whose activities are found to be prejudicial to the maintenance of supplies of commodities essential to the community. Detentions are made by the States/UTs in selective cases to prevent  hoarding  and  black-marketing  of  the  essential commodities. Under the provisions of this Act, the State Governments are required to report the facts together with the grounds of detention and other particulars relating to it, to the Central Government within seven days of approval of the State Government

 

 

 

 

 

 

 

 ISO 9000 Quality Management System

·       It is looked at as a system with minimum quality requirements.

·       A quality system is a mechanism by which a company can organize and manage its resources to achieve, sustain and improve quality economically.

Benefits of ISO 9000 quality system:

        It enables the user to identify and plan tasks and their method of performance.
        It provides the means of identifying and resolving problems and preventing their re- occurrence, thereby improving conformance.
        It cuts down the poor quality cost.
        It generates objective evidence to demonstrate the quality of products and the effectiveness of the systems and thus builds up confidence among customers.
        This standard demands training for all personnel performing activities effecting  quality and hence improved performance.
        Reduces fire-fighting operations and better job satisfaction.
        Registration to ISO 9000 is a necessary prerequisite in different countries.
        It is not a product standard and hence can be used for any type of industry and for companies employing very few persons as well as whose work force runs in to thousands.
        Marketing advantages, recognition and publicity.
        Reduces liability risks.

Essential steps to ISO 9000:

        Acceptance by top management of quality as a vital element in the business
        Consultation with the workers‟ representatives to explain the concept and benefits of ISO 9000.
        Training task force members in the various aspects of ISO 9000 and the  methodology for its implementation
        Writing down work instructions, procedures, and manuals complying with the various clauses of the standard       Preparing a quality manual setting out the company‟s policy and ensuring that these are better understood by all employees.
       Training staff and work men in the methods and procedures.
        Implementing the document system and subjecting to a trial for few months.
        Conducting internal audits to assess its compliance with the ISO 9000 standard and taking corrective action.
        Arranging a preliminary audit by an external audit team.
        Arranging formal assessment by an accredited certification or registration body.

ISO 14000 Quality Management Systems


ISO 14000 is designed to provide a structure for the management of environmental compliance. The ISO 14000 series comprises numerous individual generic standards, which may be broadly classified according to the following six categories: Environmental Management Systems (EMSs), Auditing, Labeling, Performance Evaluations, Life Cycle Assessment, and Environmental Aspects of Product Standards.

The most familiar standard in the 14000 series is ISO 14001, entitled "Environmental Management Systems, Specification with Guidance for Use." Before being published in its final form, 14001 was widely distributed and closely studied as a draft international standard. Organizations will be able to register only to this one standard; all other standards in the series are guidelines to help companies set up, audit, and improve their environmental management systems.

Like ISO 9000, ISO 14000 is neither industry- nor product-specific. The anticipated benefits of registration to this new international standard include:

·       Worldwide focus on environmental management.
·       Promotion of a voluntary consensus standards approach.
·       Harmonization of national rules, labels, and methods through minimization of trade barriers and complications and promotion of predictability and consistency.
·       Demonstrated    commitment    to    maintaining    and    moving    beyond    regulatory environmental-performance compliance.

By implementing ISO 14000, any company can become truly competitive by:

·       Decreasing costs through increased efficiencies.
·       Creating and maintaining new market opportunities in areas such as Europe, which may eventually make registration to the standards a necessary condition of doing business within their jurisdiction.
·       Demonstrating environmental leadership.
·       Improving both its own corporate image and community goodwill.
·       Enhancing credibility through registration by an independent third party accredited by the appropriate national body, such as the RAB in the United States, or the Japanese Accreditation Board.
·       Streamlining/simplifying its EMS.


Preparing for ISO 14000: Many are conducting gap analyses - that is, evaluating their existing EMSs in relation to the requirements of the current ISO 14001 draft international standard. This enables them to develop road maps for achieving registration by effectively integrating ISO 14001 into their present environmental, quality, and corporate management systems. Of the companies that have already performed gap analyses, roughly 41% feel that their existing EMS is either close or very close to meeting the ISO 14001 standard,  according to a survey carried out by ML Strategies Inc.

A number of companies in almost every industry are adopting a wait-and-see attitude, holding off on seeking registration until such time as industry conditions demand it. As a result, the first of these companies to register will be those whose customers insist on it. But while these organizations delay taking action, many others will gain competitive advantage and get a jump on the future by registering before their customers require it.

Benefits of ISO 14000: The ISO 14000 standards are practical tools for organizations who are not satisfied with mere compliance with legislation – which may be perceived as a cost of doing business. They are useful tools for proactive organizations who understand that implementing a strategic approach can bring return on investment in environment- related measures.

The systematic ISO 14001:2004 approach requires the organization to take a hard look at all areas where its activities have an environmental impact. A properly designed ISO 14001:2004 Environmental Management System (EMS) allows efficient identification of opportunities for cost savings. It can trigger procedural and/or technological changes that reduce the total cost of a product or improve its value.

Some of the benefits of implementing an ISO 14000 Environmental Management System (EMS) in accordance with the ISO 14000 standards include:

1.Operational Benefits

Hazard Analysis and Critical Control Point (HACCP)

       Hazard analysis and critical control point (HACCP) system has been recognized by the codex Alimentarius Commission as a tool to ensure the safety of food.
       HACCP is a scientifically based protocol that is applied directly to the food procurement, production and distribution process.

       HACCP / ISO 22000 food safety management system is a scientific, rational and systematic approach to identify, assess and control hazards during production, processing, manufacturing and use of food.

       HACCP is a preventive system used by the food industry to ensure food safety, pharmaceutical safety etc., which addresses physical, chemical and biological hazards as a means of prevention rather than finished product inspection.

       HACCP includes steps designed to prevent problems before they occur and  to correct deviations through a systematic way as soon as they are detected.

       HACCP system controls hazardous elements in the food system such as contaminants, pathogenic microorganisms, physical objects (glass, metal and bone), chemicals (toxins, heavy metals and pesticide residues), raw materials, processing conditions, use directions for the consumer or storage condition. So HACCP consists of plan and system.

       HACCP plan is a written document that is based on the principles of HACCP and that delineates procedure to be followed.


       HACCP presents a good opportunity for the food industry for upgrading quality and bringing uniformity and consistency in their supplies to international market.

The standard approach to HACCP is that specified by the codex Alimentarius, 1997, and follows seven basic principles:

1.    Conduct a hazard analysis

2.    Determine the critical control points

3.    Establishment of specifications for critical limits

4.    Development of monitoring and testing system to control critical point.

5.    Establishment of corrective actions when monitoring indicates that a particular CCP is not under control

6.    Establish record keeping procedures for verification to confirm that the HACCP system is under control

7.    Verification of HACCP system to confirm efficacy.

Benefits of implementing HACCP/ ISO 22000:


1.    A preventive approach to food safety

2.    Can help and identify process improvements and reduced customer complaints

3.    Reduces the need for and the cost of end product testing

4.    Is complementary to quality management system such as ISO 9000

5.    Enhances customer satisfaction/ reduces dissatisfaction

6.    Facilitates better understanding of food packaging safety issues throughout the organization

7.    Improves the organizations image

8.    Requires regular testing of data.

9.    Improves internal and external communications

 

 

 

Bureau of Indian Standards

Various committees including representatives from the government, consumers and industry, formulate the Indian Standards Institution (ISI). Safety performance and reliability are assured when the product is ISI marked. ISI is now known as Bureau of Indian standards. Bureau of Indian standards operates a certification mark scheme under the BIS Act, 1986. Standards covering more than 450 different food products have been published.

The organization runs a voluntary certification scheme known as ISI mark for certification of processed food items. Standards are laid for vegetable and fruit product, spices and condiments, animal products and processed foods.

Once these standards are accepted, manufacturers whose products conform  to these standards are allowed to use BIS label on each unit of their product. The products are checked for quality by the BIS in their own network of testing laboratories at Delhi, Mumbai, Kolkata, Chennai, Chandigarh and Patna or in a number of public and private laboratories recognized by them.

The certification scheme is basically voluntary in character but some of the items require compulsory BIS certification under PFA. They are food colors, food additives, infant milk food, infant formula, milk and cereal based weaning food, milk powder and condensed milk.

The activities are twofold the formulation of Indian standards in the processed foods sector and the implementation of standards through promotion and through voluntary and third party certification systems.

BIS has on record standards for most of processed foods. In general these standards cover raw materials permitted and their quality parameters, hygienic conditions under which products are manufactured and packing and labeling requirements.  Manufacturers complying with standards laid down by the BIS can obtain and “ISI” mark that can be exhibited on product packages.

Salient features / functions of the Bureau:

       Standard formulation

       Certification: Product, quality, management system, Eco mark, environmental management system, hazard analysis and critical control points.
        Laboratory: testing, calibration and management

        Standards: Promotion

        Consumer affairs and

       Awareness and training program.

 


Codex Alimentarius Commission

·         Codex Alimentarius Commission was established in 1962. The Codex Alimentarius which means “Food law” or “Food code” in Latin. The Codex Alimentarius Commission develops food standards, guidelines and related texts such as codes of practice under the joint FAO/WHO food standards program. It is also called Codex harmonized international standards due to involvement of both FAO and WHO.

·         The dual objectives of the Codex Alimentarius commission are to protect the health of consumers and to facilitate the international trade.

·         It brings all together all the interested parties like scientists, technical experts, governments, consumers and industry representatives to help develop standards for food manufacturing and trade.

·         These standards, guidelines and recommendations are recognized worldwide for their vital role in protecting the consumers and facilitating international trade.

·         The codex contract point in India is the Directorate General of Health Services (DGHS) in the ministry of Health; however the ministry of food processing industries is closely associated with the activities of Codex Alimentarius.

Salient features of Codex Alimentarius:


·         Protecting health of the consumers and ensuring fair trade practices

·         Promoting  coordination      of   all  food   standards   work   undertaken by  international governmental and non- governmental organizations

·         Determining priorities and initiating and guiding the preparation of draft standards

·           Finalizing the standards

·         Amending published standards

·         Submission of proposal for a standard

·         A decision by the commission or the executive committee

·         Preparation of a proposed draft standard by subsidiary body

·         Adoption of standard by the commission

·         Addition of CODEX STANDARD in the Codex Alimentarius.

The Codex secretariat is located at Rome and is financed jointly by the FAO and the WHO. At present there are 170 countries, including India as Codex members and this covers


98 per cent of the world‟s population. The codex commission meets every two years either in Rome or in Geneva.

Codex can be divided in to three main groups

1.    The commodity standards committee work vertically dealing with food products such as processed fruits and vegetables , fats and oil, fresh fruit and vegetables, natural mineral water, cocoa products and chocolates, fish and fishery products, sugar, milk, products, cereal and meat products.

2.    The general subject committees work horizontally on standards such veterinary drug residues, food additives and contaminants, pesticide residues, hygiene, labeling, inspection and certification systems, analysis and sampling, nutrition and foods for special dietary uses.

3.    The six regional coordinating committees are based in Africa, Asia, Europe, Latin America and Caribbean, North America and South West Pacific and the near East.

Codex decisions are not binding on its members not has any formal legal status, prior to the signing of the General Agreement on Tariff and trade, GATT in December 1994. Foods everywhere will ultimately be influenced by codex in many different dimensions- in safety standards, food additives, pesticide uses, labeling of pre- packed foods, international trade, competition and pricing, be the foods locally grown or imported from the other side of the world.
CODEX ALIMENTARIUS PROCEDURAL MANUAL: Criteria for the establishment of work priorities:

When a Codex Committee proposes to elaborate a standard, code of practice or related text within its terms of reference, it should first consider the priorities established by the Commission in the Medium-Term Plan of Work, any specific relevant strategic project currently being undertaken by the Commission and the prospect of completing the work within a reasonable period of time. It should also assess the proposal against the criteria set out below.
