MANUAL ON STANDARDS OF MUSTARD AND RAPESEED
1.
INTRODUCTION
Promotion of standardization and
grading of agricultural commodities is an important aspect of agricultural
marketing. The agricultural commodities are heterogeneous and hence it is very
essential to grade these commodities as per standards to command better price
either at domestic or international market.
2. OBJECTIVE
The Manual has been
designed with the objectives to
i.
Create
awareness about standards prescribed by various organizations for domestic and
international markets so as to raise quality consciousness among the farmers,
entrepreneurs and other market functionaries with the objective to equip them
better to face the global competition in the post WTO era.
ii.
provide
details of various parameters responsible for quality; and
iii.
describe
the advantages of grading & standardization so that farmers may get prices
commensurate with the quality produced by them.

5. STANDARDS APPLICABLE
FOR STORAGE OF MUSTARD AND RAPESEED
5.1
CENTRAL WAREHOUSING CORPORATION (CWC) : The CWC works as an
agent of the government for purchase,
sale, storage and distribution of agricultural and industrial commodities,
seeds, fertilizers and notified commodities for individual, cooperatives and
other institutions in the country. CWC
provides modern efficient warehousing to ensure maximum returns to the growers
with better opportunities. It provides scientific facilities to the farmers for
the stock of agricultural produce at a reasonable cost. CWC issues Warehouse Receipts to a person
depositing goods in the warehouse. The
banking institutions accept the Warehouse Receipts as co-lateral security for
grant of loans to the holder of the Warehouse Receipt on its being endorsed and
delivered to them. Thus, warehousing
plays an active role in marketing and also provides socio-economic gains to the
farmers, who otherwise get exploited by the middlemen and are forced to have
distress sales.
5.1.1 Standards of
Central Warehousing Corporation
General Characteristics
Mustard seeds to be accepted in ware house shall be :
(a)Free from visible moulds and
insect infestation live or dead, any other deleterious substance and musty
odour
(b)Free from harmful seeds such as Argemone
seeds.
(c) Reasonably dry, and
(d)In sound merchantable condition, having the pungent characteristic smell
of the variety of the mustard supplied.
Special Characteristics:
The grading may be done on the basis of extraneous matter, damaged ,
discoloured and dead seeds, shriveled, immature and slightly damaged seeds,
admixture of other varieties of mustard , the presence of small atrophied seeds
, and presence of whole sound seeds present in the sample.

6. STANDARDS APPLICABLE FOR DOMESTIC MARKET
6.1 The Prevention of Food Adulteration
Act, 1954 (PFA Standards)
Prevention of Food
Adulteration Rules, 1955 (PFA Rules) have been notified to carry out the provisions
of the Prevention of Food Adulteration Act, 1954. These rules define the
standards of quality and fix the limit of variability permissible in respect of
article of food. These rules also provide guidelines for packing and labeling
of an article of food. Standards framed under the provisions of the Rules are
popularly called PFA standards. PFA standards prescribe minimum limit for
Quality as well as Safety parameters. PFA standards are minimum standards and
are mandatory.
They do not differentiate between Quality. Food articles being
sold in the market should comply with PFA standards. Standards of Mustard
and Rapeseed prescribed in PFA Rules, 1955 are as follows :

7.STANDARDS FOR GRADING
7.1 GRADING
- Grading provides description of the
quality of the consignment and assists in the formation of a legally binding
agreement. It facilitates proper marketing of agricultural commodities. It also ensures that agricultural commodities
move through the market faster and
without obstructions. This also
facilitates transactions without physical verification by the distant buyers.
Advantages of Grading
-
It brings confidence between the buyer and
the seller.
-
It facilitates interstate and
international marketing.
-
Disputes in the market can be solved
amicably.
-
Stability of the price is ensured.
-
Farmers can take loans easily from the
banks on the basis of grades of produce stored in the godown
-
Arbitrary fixation of price by middlemen
is eliminated.
-
Brings about improvement of the crop.
-
Reduces risk of producer and seller in
transactions.
-
Future marketing is facilitated. Grades
become a commercial measure of quality.
-
It also helps in implementation of
contract farming.
7.2 AGRICULTURAL PRODUCE (GRADING & MARKING)
ACT, 1937 (AGMARK STANDARDS).
Standards of various agricultural commodities
prescribed under the provisions of the Agricultural
Produce (Grading & Marking) act, 1937 are popularly called AGMARK
Standards. AGMARK standards comply with
minimum standards of quality & safety prescribed in Prevention of Food
Adulteration Rules, 1955. In addition
AGMARK standards differentiate between quality by having three grades for
Mustard and Rape seed. The grades are differentiated
on the basis of foreign matter, dead badly discoloured and damaged, unripe shriveled and slightly damaged ,small atrophied
seeds, admixture of other varieties of seed etc .
