Eco-friendly coating engineered with antimicrobial lipopeptides maintains freshness and induces genes expression in anthocyanin biosynthesis of blueberry.

Blueberries with high anthocyanin content undergo various postharvest qualitative losses. In this work, eco-friendly coatings were developed for maintaining postharvest blueberry quality using lipopeptides (LPs), gelatin, and sodium carboxymethyl cellulose. The addition of LPs decreased the surface tension of coating film and thus exhibited lower water contact angle (95.
