摘　　要：为提高双孢菇干制品品质,探讨了抗坏血酸、柠檬酸、氯化钙、氯化钠和电生功能水的护色效果,以及梯度升温、恒温连续、梯度降温三种热风干燥方式对护色双孢菇干制品品质的影响。结果表明,各护色剂的浓度分别为抗坏血酸0.04g/100mL、柠檬酸0.2g/100mL、氯化钙0.3g/100mL、氯化钠0.2g/100mL和电生功能水浸泡10min时,干制品的L*值最大,护色效果最好。通过正交优化实验得出非硫复合护色剂的最佳组合为:抗坏血酸0.04g/100mL,柠檬酸0.3g/100mL,氯化钠0.3g/100mL;三种热风干燥方式中,采用梯度升温干燥的双孢菇褐变最少、复水性最好,优于恒温连续干燥和梯度降温干燥。In order to improve the quality of dried Agaricus bisporus,the effect of color protection were discussed including ascorbic acid,citric acid,calcium chloride,sodium chloride and electrolyzed functional water,and three hot air drying way of the gradient temperature rise,constant temperature and gradient temperature decline were studied on dried Agaricus bisporus quality. The results showed that the L＊ value was the highest and the color protection effect was best when the concentrations were ascorbic acid （0.04g/100mL） ,citric acid （0.2g/100mL） ,calcium chloride （0.3g/100mL） ,sodium chloride （0.2g/100mL） and electrolyzed functional water（soaking 10min ） respectively. Using the orthogonal array design ,the best combination of non-sulfite color protection was ascorbic acid （0.04g/100mL）,citric acid （0.3g/100mL） and sodium chloride（0.3g/100mL）. Among the three drying ways,the gradient temperature rise drying yielded products with least browning and best rehydration properity,better than the constant temperature drying and gradient temperature decline drying.
