,MARKING, LABELLING & SEALING
1. The key to the success in grading of a lot lies in drawing a truly representative sample, which reveals the exact composition of the commodity.
2. Primary sample. Each sample drawn from the heap or bag by Parkhi or Tube sampler from a single position of the Lot.
3. Composite sample: Primary samples drawn from the same lot shall be thoroughly mixed and blended to form homogeneous composite sample in a sample divider.
4. Test sample: One portion of composite sample weighting 500 gms. And packed in cloth bag.
5. Sample for Moisture: Part of the composite sample weighing about 250 gms. Pakced in polythene bag and heat-sealed kept in airtight container.
6. Labelling of sample: Gives all the details of the commodity, ie., Lot Number, quantity, name etc. Label is affixed to the sample pack and sealed.
7. Sampling from bags: from bulk or heap depending upon lot size r = N/n, where N= No. Containers and n= Number of Containers to be sampled. Every rth bag is to be sampled.

SAMPLE SIZE FOR ANALYSIS:
Weight in Grams
Small oil seeds (sesam, mustard, poppy, rape,
Linseed, hemp, cotton seed and others in the
Size range) 10.00
Medium oil seeds (Castor,palm, kernel, Groundnut,
Soyabean, mahua and others) 100.00
Large oil seeds (Copra and other oil seeds in the
Same size range) 500.00
Wheat, maize, bareley, jowar, whole pulses 50.00
Split pulses, husked & unhusked 20.00
APPARATUS AND EQUIPMENTS FOR PHYSICAL ANALYSIS:
Enamelled tray, Analytical Balance, Sample Scoop, Standard Set of Sieves, Magnifying glass, Sample Bottle, Universal Electronic Moisture Meter or Farmex Electronic Moisture Meter.
All particulars of the sample should be checked and entered in a Register
For analysis, sample should be emptied on a flat smooth surface, thoroughly mixed on the table in a circular layer of 1.5 cm to 5 cm thickness.
Oil seeds should be smoothly scooped out from the Center, sides and different point on the surface all round and weighed exactly.
Oil seeds having greenish tinge on seed coat should be separated by hand in gloves to prevent the spread of aflatoxin.
If Argemone mexicana seeds are found in mustard/rape seed, the same should be sieved out to avoid health hazard.
SIZE OF COMPOSITE SAMPLES:
200 gms for small oil seeds
600 gms for medium oil seeds
1000 gms for large oil seeds
Sample is poured over set of sieves, agitated thoroughly to strain out the foreign matter at various levels.
The sieves are then separated and all the foreign matter is picked up ;by hand and added to the foreign matter collected at the bottom and per centage of FM is obtained.
Top sieve will contain bold seeds and lower sieve will contain smaller one.
The contents of the upper sieves should be mixed and spread out evenly in a thin circular layer. From this surface, prescribed size of the sample for analysis may be taken.
For groundnut, a separate small lots of 100 gms would be taken for determination of shelling percentage (Kernels/Pods)
Moisture of oil seeds is determined by the Hot Air Oven method, heating at 135 + 3 C for two hours. Only hermetically sealed sample separately drawn for the purpose should be used.
METHOD OF ANALYSIS FOR FOODGRAINS:
Grains having greenish tinge on seed coat should be separated by hands in gloves to prevent the spread of aflatoxin. Thoroughly mix and spread the sample on the table or glass tops in a circular layer of about 1.5 to 2.5 cm thickness and even out with a ruler. Smoothly scoop out the sample from the Center, sides and different points on the surface all around and weigh exactly 250 gms. Of samples, taking care that no dirt is left over from the sample, which has been removed. Pour the sample over the appropriate sieve and remove the dirt component of the foreign matter. Weigh the dirt and multiply it by 0.4 to work out the percentage. Analyse on an enamelled tray and calculate percentage of each refraction on weight basis and assign the grade on the basis of analytical data on factorial basis.
CERTIFICATION: A procedure by which a third party gives written assurance that a product, process or service conforms to specified requirements. Certification involves the issue of, a certificate or a mark (or both) to demonstrate that a specific product meets a defined set of requirements for that product, usually a standard.
The mark carries a reference to the number or name of the relevant product standard against which the product has been certified .A product bearing a mark carries a third party guarantee that-
q The product has been produced according to specified standard
q Production has been supervised and controlled
q Product has been tested and inspected
Customers can approach certification agency, if the product does not meet the declared standards
Certification agency uses various evaluation techniques, before issuing the certificate such as testing of the product, in process quality control, surveillance visit to factory and testing the samples drawn from the open market.
In India, for agricultural commodities, Directorate of marketing &Inspection, Govt of India, is the designated certification body, which is empowered to issue the certificate to the quality of notified commodities graded under Agmark. Generally, Agmark standards are accepted internationally, however, with the advent of WTO, the international requirements for quality have become more specific (Codex Standard) and need to be incorporated in the domestic or national standards strictly, to match them with the standards prevailing in the international parlance.
For products in the regulated sector, one can contact the enquiry points ( In India, it is Director (Quality system), Bureau of Indian Standards, Manak Bhavan, 9- Bahadur Shah Zafar Marg, New Delhi – 110002) setup in the country under WTO agreement on TBT and from these points, the needed information, technical regulation and conformity procedures may be obtained from its counterparts in the target market.
A supplier’s declaration of conformity is a procedure by which a supplier gives written assurance that a product, process or service conforms to specified requirements. The details include-
q Name and address of supplier
q The identification of the product, process or service
q Conformity statement
q The reference normative document(standards, technical regulation etc)
q Date and place of issue of declaration
q The authorised signatory on behalf of the supplier
PACKING:- Agricultural commodities should be packed in new packing material which is hygienic and capable of maintaining the quality including organoleptic characteristics and quantity of the produce intact during the course of its distribution .Generally for foodgrains new ,clean jute bags, cloth bags, polywoven bags, polyethylene, high density ployethylene or other foodgrade plastic / packaging material free from any insect infestation or fungal contamination, which are safe and suitable for their intended use are used .They should not impart any toxic substance or undesirable odour or flavour to the produce Produce should be packed only after proper drying, cleaning and grading.Package should contain only one grade produce in standard pack size( As per the provisions of PFA Act 1955 and Packaged Commodity rules 1977; if the consignment is for export, it should conform to the provisions of Technical Barriers to Trade –TBT).

MARKING :Marking is the action and result of stamping, inscribing ,printing,labelling etc, marks, symbols, numeral letters etc upon a product itself or on its package, for the purpose of identifying the product and its origin and giving its basic characteristic its intended use etc.
LABELLING: It is a means for the identification and presentation of a container or package, a means for protecting the contents against pilfering as they form a security- seal. Gives information regarding batch number or quality control reference, may either be printed directly on the packaging or on the printed label itself by the packer applying the label. Following details on each package clearly and indelibly marked-
1. The grade designation mark shall be securely affixed to or printed on each package in a manner approved by the Agricultural Marketing Adviser or an officer authorised by him in this behalf.
