PADDY
The basis of categorization of paddy is the same as the case of wheat except for
incorporating the “designation” to indicate the intensity of slightly damaged/ dicoloured kernels.
Designation
Percentage of slightly damaged/ discoloured besides
touched/ damaged and discoloured grains.
1.
Upto 5
2.
Above 5 upto 10
3.
Above 10 upto 15
4.
Above 15 upto 20
Example:
Paddy grains with 1% of weevilled and 3% of slightly damaged/discoloured and
damaged/ discoloured grains will be categorized as A1.
CLASSIFICATION OF FOODGRAINS
Foodgrains in storage shall be classified as „Clear‟, „Few‟ and „Heavy‟ based on the
presence of insect population as indicted below:
a.
Clear
Lot completely free from any living infestation.
b.
Few
Lot having upto two living insects per 1 kg. of
representative sample.
c.
Heavy
Lot having more than two living insects per 1 kg. of
representative sample
GUIDELINES FOR SAFE STORAGE OF FOODGRAINS
 Grain should be „Clean‟ & „Dry‟.
 Godown should be storage worthy. Proper dunnage be used to avoid damage to bottom
layer due to seepage.
 Godown should be properly cleaned and sprayed before storage of grain.
 Periodical inspection of stock should be conducted every fortnight & regular prophylactic
measurers should be undertaken.
 Immediate curative treatment should be given in case of infestation and rodent control
measures should be adopted, if needed.
 Regular aeration of foodgrains is necessary for control of moisture, temperature and
infestation.
 Liquidation of stock should be done on “first-in-first out” (FIFO) basis so as to avoid
damage to stock due to prolonged storage.
UNIFORM SPECIFICATION OF RICE
(KMS 2014-15)
Rice shall be in sound merchantable condition, sweet, dry, clean, wholesome, of good
food value, uniform in colour and size of grains and free from moulds, weevils, obnoxious smell,
admixture of unwholesome poisonous substances, Argemone mexicana and Lathyrus sativus
(Khesari) in any form, or colouring agents and all impurities except to the extent in the schedule
below. It shall also conform to PFA Standards.
