摘要
以新鲜香菇为主要原料,采用4种护色剂对香菇脆片前处理过程中护色效果进行研究;在浸渍工艺中选取5个糖液质量分数梯度对香菇脆片的最佳糖液质量浓度进行研究。结果表明,柠檬酸质量分数0.6%~1.4%,抗坏血酸质量分数0.06%~0.12%,L-半胱氨酸0.2%~0.6%,食用盐3%~6%时,对香菇脆片的护色作用较好;采用L9（34）正交试验,利用4种护色剂的协同作用,得到护色剂的最佳配比为柠檬酸0.8%,抗坏血酸0.07%,L-半胱氨酸0.6%,食用盐5%;糖液质量分数在30%时,香菇脆片的感官评分最高达到9.46分。
Choosing fresh mushroom as the main raw material for vacuum-frying mushroom chips,effects of four kind of color fixative on the color protection effect for vacuum-frying mushroom chips are investigated. Selects five sugar concentration gradient on mushroom chips of the optimum concentration of sugar in the impregnating process. The results show that 0.6%~1.4% citric acid,0.06%~0.12% VC,0.2%~0.6% L-cysteine,3%~6% Na Cl has good color-protection effects on mushr-oom chips. L9（34）test show that the optimum compound reagent for color-protection of mushroom chips is a mixture of 0.8%citric acid,0.07% VC,0.6% L-cysteine and 5% Na Cl. Mushroom chips of sensory scores reach 9.46 points when Sugar concentration in 30%.
