Fresh-cut apple preservation is a critical concern in the food industry due to the rapid deterioration of texture, color, and flavor. While our previous study introduced apple essence microencapsulation (AEM) to enhance flavor during storage, its impact on overall storage quality was minimal. Thus, this study explores the application of two preservation techniques, namely, slightly acidic electrolyzed water (SAEW) and chitosan-apple essence microencapsulation (CH-AEM) coating, to enhance the quality of fresh-cut apples. Our findings reveal that SAEW treatment significantly reduces the browning index (from 65.38 to 57.36) and respiratory rate (from 5.10% to 4.30% of CO), and maintains a desirable aroma profile compared to uncoated treatment during 10 days of storage. Additionally, the CH-AEM coating acts as a protective barrier, further preserving the sensory characteristics of fresh-cut apples. Notably, the SAEW-CH-AEM group exhibits superior performance in firmness (8.14 N), respiratory rate (3.37% of CO), ion leakage (34.86%), and juice yield (47.52%) after 10 days. Our research highlights the synergistic effect of combining these preservation strategies, providing a promising approach for extending the shelf life of fresh-cut apples while maintaining their visual appeal and aromatic quality. These results offer valuable insights for the fresh-cut produce industry, contributing to improved apple product preservation and consumer satisfaction.
由于鲜切苹果的质地、颜色和风味会迅速劣化,其保鲜是食品行业的一个关键问题。虽然我们之前的研究引入了苹果香精微胶囊化(AEM)来在储存期间增强风味,但其对整体储存质量的影响微乎其微。因此,本研究探索了两种保鲜技术的应用,即微酸性电解水(SAEW)和壳聚糖-苹果香精微胶囊化(CH-AEM)涂层,以提高鲜切苹果的品质。我们的研究结果表明,与未处理的对照组相比,SAEW处理显著降低了褐变指数(从65.38降至57.36)和呼吸速率(从5.10%降至4.30%的CO₂),并在10天的储存期内保持了理想的香气特征。此外,CH-AEM涂层起到了保护屏障的作用,进一步保持了鲜切苹果的感官特性。值得注意的是,SAEW-CH-AEM组在储存10天后,在硬度(8.14 N)、呼吸速率(3.37%的CO₂)、离子渗漏(34.86%)和汁液产量(47.52%)方面表现出卓越的性能。我们的研究突出了结合这些保鲜策略的协同效应,为延长鲜切苹果的货架期同时保持其视觉吸引力和香气品质提供了一种有前景的方法。这些结果为鲜切农产品行业提供了有价值的见解,有助于改善苹果产品的保鲜并提高消费者满意度。
