【摘要】 为了研究不同冷冻处理速度对苹果贮藏品质的影响，分别采用0.5℃/min和3.5℃/min两种冷冻速度对苹果进行冷冻处理，分析苹果贮藏期间的品质变化。结果表明：冷冻处理速度显著影响苹果的贮藏品质。高冷冻速度处理的苹果品质损伤更小且苹果硬度、可溶性固形物、维生素C含量更高，口感、营养价值更好；同时L~*值更高，a~*值、b~*值更低，外表面颜色保持得更鲜艳。更多还原

【Abstract】 To study the effects of different freezing speeds on the storage quality of apples, two freezing speeds of 0.5 ℃/min and 3.5 ℃/min were used to freeze the apples respectively, and the quality changes of apples during storage were analyzed. The results showed that the freezing speed significantly affected the storage quality of apples. Apples treated at high freezing speeds had less quality damage, higher apple hardness, soluble solids, and vitamin C content, better taste and nutritional value. At the same time, the L~* value was higher, the a~* value and b~* value were lower, the color of the outer surface remained more bright.更多还原
