涂膜处理和酸处理对提高双孢蘑菇储藏稳定性的研究

Application of edible coating and acidic treatment for improving the storage stability of Agaricus bisporus

摘要: 为了提高双孢蘑菇(Agaricus bisporus)的储藏稳定性,本研究分别采用了三种不同的方法对双孢蘑菇进行处理,它们分别是:酸处理、涂膜处理和酸与涂膜相结合的处理,然后分别测定了储藏过程中的失重率、硬度、色泽变化、多酚氧化酶(PPO)活力和过氧化物酶活力(POD),探讨了不同处理方法对双孢蘑菇储藏稳定性的影响。结果表明:酸与涂膜相结合的处理方式具有最优的效果,它能弥补酸处理和涂膜处理各自的不足之处,既能降低失重率,保持硬度,又能抑制酶活,更好地保持双孢蘑菇的色泽。

Abstract: In order to improve the storage stability of Agaricus bisporus, Agaricus bisporus was treated in three different methods, including:edible coating treatment, acidic treatment, and the combination of acidic treatment and edible coating treatment.The weight loss, firmness, color change, polyphenol oxidase activity, peroxidase activity were determined respectively.The results showed that the Agaricus bisporus treated with the combination of acidic treatment and edible coating treatment had the best storage stability, which could effectively decrease the weight loss, maintain firmness, inhibit enzyme activities, and maintain the colour.
