Effect of Storage Environment on Quality of Coarse Paddy

To solve the problem of storage loss, a study was conducted on flexible hermetic storage system for paddy grain with an objective to find the effect of different packaging material on quality. The storage environment includes gas composition around the grain. The gas composition mainly affects grain quality includes O2 and CO2. The O2 concentration affects respiration of the grain and insect population. The CO2 directly controls the growth of the insects. The CO2 replaces phosphine to control the insect growth. The moisture migration to and from the grain is not prevented by jute bag, HDPE woven lined and unlined bags. This affected the quality parameters of paddy. The PP bags could arrest the moisture transmission up to some extent which helps in restoring quality parameters of paddy. The lower oxygen content and higher carbon dioxide content in the package could retain the paddy quality. The super grain bag arrested both moisture migration and gas transmission to and from the grain which intern retained grain quality better than the other packages.
