Development of Hermetic Storage System for Groundnut

ABSTRACT This study evaluated the storage behavior of groundnut under two experiments. In the first, grains were stored in PVC drums at 40% CO 2 concentration. In the second, hermetic, traditional polyethylene, and jute bags were used, with oxygen absorbers (iron filings, 40 g, and NaCl, 4 g) for 50 kg grains to reduce O 2 levels to ~10%. Cocoon bag was exclusively tested for groundnut storage. Hermetic bags maintained higher CO 2 levels (7.81%) compared to polyethylene (3.48%) after 180 days. Cocoon bag stabilized CO 2 at 48% and O 2 at 9.6%, minimizing free fatty acid changes (0.43% to 0.68%). Thousand‐grain weight losses were minimal, with final weights of 872.20 g. The study demonstrated hermetic systems' potential to reduce post‐harvest losses and maintain seed viability.
