Effect of Different Polythene Bags on Plw and Chlorophyll and Carotenoid Content of Pea Grains During Ambient and Zero Energy Chamber Storage

Pea vegetable grains cv. Arkil were packed in three different types of plastic bags of two thickness each viz., high density polyethylene (HDPE 100 and 200 gauge), low density polypropylene (LDPP 100 and 200 gauge) and polyvinyl chloride (PVC 100 and 125 gauge). Pea pods in control were packed with newspaper lining. Pea grains after packing were stored at room temperature and zero energy chamber. PLW in pea grains increased with the increase in period of storage. Zero energy chambers reduce the physiological loss of weight (PLW) as compared to ambient room temperature. LDPE was most effective in reducing PLW. All the polythenes were effective to reduce PLW in pea grains. Higher chlorophyll content was retained in zero energy chamber stored grains as compared to ambient room temperature stored pods. Carotenoids content increased with the increasing period of storage. Zero energy chamber stored grains had less content of carotenoids as compared to ambient room temperature storage grains.
