Abstract
In the present study pearl millet (Pennisetum glaucum) PBH1625 variety (whole
grain, dehulled grain, and dehulled flour)was subjected to cold plasma exposure at 25kv for 10 mins
and 30kv for 10 mins. Subsequently, the samples were packed in low-density polyethylene (LDPE)
pouches and metalized polypropylene (MPP) stored for 90 days, and shelf life studies were
conducted. The results revealed that cold plasma exposure at 25kv for 10 mins outperformed in
controlling lipase and lipoxygenase activity at 30kv for 10 mins. On storage, MPP packaging
material outperformed LDPE in controlling moisture, acid value, free fatty acids, peroxide value,
water activity, lipase, and lipoxygenase activity in all the samples. The findings collectively indicate
that pearl millet whole grain, dehulled grain, and dehulled flour exposed to cold plasma at 25kv for
10 mins followed by packing in MPP have better shelf life and storability up to 90 days.
