Cold plasma treatment on pearl millet grain and flour: Impact on bio actives, physical and functional properties

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 25 kv for 10 mins and 30 kv 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 25 kv for 10 mins outperformed in reducing tannin content. On storage MPP packaging material outperformed LDPE in controlling tannin content. The findings collectively indicate that pearl millet whole grain, dehulled grain and dehulled flour exposed to cold plasma at 25 kv for 10 mins followed by packing in MPP have better shelf life and storability upto 90 days.
