摘要
以新鲜双孢菇为原料,采用响应面法对其护色工艺进行优化。选用不同浓度的柠檬酸、柠檬酸亚锡二钠(DSC)、L-半胱氨酸、异抗坏血酸钠作为自变量,以双孢菇褐变程度作为响应值,采用Box-Behnken中心组合法研究自变量及其交互作用对其褐变度的影响,并利用Design-Expert软件得到回归方程预测模型并进行响应面分析。结果表明,柠檬酸0.97%,柠檬酸亚锡二钠0.05%,L-半胱氨酸0.57%,异抗坏血酸钠为0.53%,此时双孢菇切片褐变度的实测值为2.52,护色效果较好。
In this paper,the technology of anti-browning of Agaricus bisporus was optimized by response surface methodology.According to the effects of single factor test,four main factors about citric acid,disodium stannous citrate（ DSC）,sodium erythorbate,L-cysteine were variables,and Agaricus bisporus browning degree was response value,the experimental design method of Box-Benhnken was used to study the effects of each variable and their interactions on the Agaricus bisporus browning degree.The prediction model of regression equation by using Design Expert software was analyzed by response surface analysis.The result showed that the optimum conditions of anti-browning were that mass fraction of citric acid 0.97%,citric acid stannous disodium 0.05%,L-cysteine 0.57%,sodium erythorbate 0.53%.Under this condition,the prediction value of Agaricus bisporus browning degree was 2.52 and the color proction effect was good.
