以新鲜鸭梨为原料,采用不同浓度的抗坏血酸钙溶液浸泡处理鲜切鸭梨,研究了其在4℃贮藏条件下的感官及理化品质变化。结果表明:抗坏血酸钙处理可抑制鲜切鸭梨的褐变,减弱其软化程度,减缓膜透性的增大及抑制多酚氧化酶的活性,保持鲜切鸭梨的外观品质和营养价值。

With fresh yali pear as the raw material,different concentrations of calcium ascorbate solution to soak the fresh-cut Yali pear was performed to study the sensory and physical and chemical change on the storage at 4℃.The results showed that the calcium ascorbate treatment can inhibit the browning of fresh-cut Yali pear,reduce the degree of softening,delay the increase of membrane permeability and inhibit the activity of PPO,and maintain the appearance quality and nutritional value of the fresh-cut Yali pear.
