The effect of wheat straw arabinoxylan (AX) and β-glucan stearic acid ester (SABG) composite coating on the quality and storage life of apple (Royal Delicious) was studied at 22 °C (±2) with relative humidity of 65% and 85% for 60 days. Fresh fruits were coated with surface coatings of AX-SABG, shellac in the concentration range of 1-4%. Application of both AX-SABG (1-4%) and shellac (1-4%) coatings was found to significantly reduce weight loss, respiration rate, fruit softening process, ripening index, color degradation and polyphenol oxidase activity compared to control during the storage period of more than 30 days. However, an AX-SABG coating was more effective in reducing fruit decay and loss of aroma volatiles followed by shellac coated apples; the un-coated apples being showing maximum quality deterioration. These findings confirmed the potential benefits of applying AX-SABG coating to extend the shelf life and quality of apples especially during transportation and storage.
研究了小麦秸秆阿拉伯木聚糖（AX）和β-葡聚糖硬脂酸酯（SABG）复合涂层对苹果（皇家美味）品质和贮藏寿命的影响。在 22°C（±2）、相对湿度为 65%和 85%的条件下，贮藏 60 天。新鲜水果用 AX-SABG、虫胶的表面涂层在 1-4%的浓度范围内进行涂覆。与对照组相比，在贮藏期超过 30 天的时间里，AX-SABG（1-4%）和虫胶（1-4%）的应用均显著降低了失重率、呼吸速率、果实软化过程、成熟指数、颜色降解和多酚氧化酶活性。然而，AX-SABG 涂层在减少腐烂和香气挥发损失方面比虫胶涂层苹果更有效；未涂层的苹果表现出最大的质量恶化。这些发现证实了应用 AX-SABG 涂层来延长苹果的货架期和品质的潜力，特别是在运输和储存期间。
