Original Paper


Effect of pomegranate peel extract (PPE) in two polysaccharide-based edible coatings namely chitosan and alginate on capsicum (Capsicum annuum L.) was studied during storage at 10 °C. The characterization of PPE confirmed the presence of polyphenols such as punicalagin, catechin, and rutin. PPE also demonstrated antifungal activity against the fungal strain of Colletotrichum gloeosporioides. Incorporation of PPE in chitosan coating recorded significant (P < 0.05) retention of physiological loss in weight, firmness, color, and ascorbic acid in the samples as compared to the control. The restricted losses in total chlorophyll were found to be 22, 29, 38, and 48 in the samples coated with PPE-enriched chitosan, chitosan alone, PPE-enriched alginate, and alginate alone respectively as compared to higher loss of around 71% in control samples during storage. The addition of PPE in these two coatings could also inhibit the microbial growth, maintain sensory scores, and extend the shelf-life up to 25 days at 10 °C.
