Punjab’s state procurement agencies (SPAs) are seeking a waiver of ‘storage gain’.
What is ‘storage gain’ in wheat?
- Wheat, considered a ‘living grain’, tends to gain some weight during storage.
- This is known as ‘storage gain’ and it mostly happens due to absorption of moisture.
- There are three parts of the grain — bran (outer layer rich in fibre), germ (inner layer rich in nutrients) and endosperm (bulk of the kernel which contains minerals and vitamins).
- The moisture is mostly absorbed by the endosperm.
Who compensates whom for ‘storage gain’?
- State procurement agencies, which purchase and store wheat at their facilities, are required to give one kg wheat extra per quintal to the Food Corporation of India (FCI).
- While 20% of wheat, procured by the FCI and the SPAs, is moved immediately after procurement.
- It is usually on the remaining 80%, which is moved out after July 1 every year that storage gain has to be accounted for due to longer storage duration.
