This study investigated the effect of an edible water-extractable arabinoxylan (WEAX) coating on the postharvest preservation of strawberries and cherries. The WEAX film was prepared using carboxymethyl chitosan (CMCS) film as a control, with thorough characterization of its film properties. Subsequently, strawberry and cherry fruits were submerged in a solution containing edible film-forming materials and left to be stored at room temperature, followed by the analysis of their physicochemical parameters to assess their preservation efficacy. The results show that the WEAX film exhibited enhanced flexibility, superior water vapor permeability, thermal stability, and surface morphology. Furthermore, the implementation of WEAX film effectively mitigated weight loss, decay, color degradation, softening process, ascorbic acid decline, anthocyanin accumulation, and an increase in malondialdehyde content in fruits. Thus, the incorporation of WEAX coating demonstrates its capability in prolonging the shelf life of fruits post-harvest, underscoring its potential in fruit preservation practices.
本研究调查了可食用的水可提取阿拉伯木聚糖（WEAX）涂层对草莓和樱桃采后保鲜的影响。以羧甲基壳聚糖（CMCS）膜为对照制备了WEAX膜，并对其膜性能进行了全面表征。随后，将草莓和樱桃果实浸泡在含有可食用成膜材料的溶液中，在室温下储存，然后分析其理化参数以评估其保鲜效果。结果表明，WEAX膜具有增强的柔韧性、优异的水蒸气渗透性、热稳定性和表面形态。此外，WEAX膜的应用有效减轻了果实的重量损失、腐烂、颜色退化、软化过程、抗坏血酸下降、花青素积累以及丙二醛含量的增加。因此，添加WEAX涂层证明了其延长果实采后货架期的能力，突出了其在水果保鲜实践中的潜力。
