The ability of chitosan produced from pupal exuviae of to retard the decay of the local strawberry ( cultivar was investigated for the first time in this paper. The results demonstrated the effectiveness of insect chitosan compared to the commercial polymer in preserving and enhancing, at the same time, some physicochemical parameters (weight loss, pH and soluble solids content) and nutraceutical properties (total polyphenol content, total flavonoid content and total antioxidant activity) of strawberries stored at RT, 4°C and at mixed storage conditions (4°C + RT). Moreover, chitosan from was also effective in reducing fungal decay and improving fruit shelf life. The obtained results confirm that insect chitosan, particularly deriving from pupal exuviae, can be a viable alternative to crustacean one in safeguarding postharvest fruits.
本文首次研究了由蚕蛹蜕皮产生的壳聚糖延缓本地草莓(品种 )腐烂的能力。结果表明,与商业聚合物相比,昆虫壳聚糖在保存和提高同时处于室温、4°C以及混合储存条件(4°C + 室温)下草莓的一些理化参数(失重、pH值和可溶性固形物含量)和营养特性(总多酚含量、总黄酮含量和总抗氧化活性)方面是有效的。此外,来自蚕蛹蜕皮的壳聚糖在减少真菌腐烂和延长果实货架期方面也很有效。所得结果证实,昆虫壳聚糖,特别是来自蚕蛹蜕皮的壳聚糖,在保护采后水果方面可以成为甲壳类壳聚糖的可行替代品。
