Impact of Packaging Materials on Shelf Stability of Red Chilies under varying Temperature and Humidity Conditions

Abstract This study was conducted to examine the effect of packaging materials on aflatoxin contamination and quality retention in Capsicum annuum L (Dundicut). Chilli pods (intact and physically damaged) from 15 locations in Sindh, Pakistan, were stored for 45 days in low-density polyethylene (LDPE), polyethylene (PE), polypropylene (PP), and aluminum (Al) bags under uncontrolled conditions (19–41 °C; 48–99% RH). Aflatoxin levels showed a non-significant increase (p > 0.05) in Al-packaged samples during storage. Damaged pods exhibited greater reductions in total phenolic content, extractable colour, and pungency index compared with intact pods across all packaging types. The lowest loss in pungency index was observed in intact pods stored in Al bags, whereas damaged control samples showed the highest deterioration. Overall quality retention followed the order: control < LDPE < PP < PE < Al. Aluminum packaging was most effective in extending the shelf life of chilli quality and limiting the development of aflatoxin during storage.
