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.
在本研究中，开发了基于木葡聚糖（XG）的可食用涂层，并将其与生物活性化合物贝叶棕种皮提取物（BFE）相结合。在环境条件下储存8天的过程中，研究了设计的可食用涂层对草莓果实品质的影响。结果揭示了涂层草莓内在特性的保存效果，即XG/BFE涂层草莓在定性参数的维持方面优于未涂层草莓，表现为重量损失、pH值和总可溶性固形物、可滴定酸度延迟，保持了硬度和亮度，并且在储存结束时总色差最小。此外，BFE的加入显著增强了所开发可食用涂层的抗菌性能，这通过降低微生物负荷得到证明。这些结果为设计活性可食用XG/BFE涂层以维持草莓采后品质并延长其在环境条件下的货架期铺平了坚实的道路。
