Abstract:
In this study, xyloglucan (XG) based edible coatings were developed and combined with a bioactive compound, Borassus flabellifer seed coat extract (BFE). The effect of designed edible coatings on the quality of strawberry fruits was investigated over an 8-day storage under ambient conditions. The results revealed the preservation effects in intrinsic properties of coated strawberries that the XG/BFE coated strawberries showed superior maintenance of qualitative parameters over uncoated strawberries, showing delayed weight loss, pH, and total soluble solids, tritratable acidity, retained firmness and lightness, as well as minimized the total color difference at the end of storage. Furthermore, the inclusion of BFE significantly enhanced the antimicrobial properties of developed edible coatings, evidenced by reduced microbial load. These results paved a solid way for designing the active edible XG/BFE coating for maintaining the postharvest quality and extending the shelf life of strawberries under ambient conditions.
