中文摘要: 为解决含硫护色剂的危害,以柠檬酸、氯化钠、抗坏血酸、植酸结合烫漂对姜脯进行护色处理,研发一种无硫护色剂。结果表明,这4种试剂复合的效果优于单独处理,利用各种护色剂的协同作用,通过正交优化试验得到护色效果较好的护色剂组合:0.7%柠檬酸+1.5%氯化钠+0.2%植酸+0.5%抗坏血酸在100℃条件下浸泡15 min,姜脯的L*值可达46.85。此复合护色剂护色效果与0.3%的亚硫酸氢钠相当,可以予以代替亚硫酸氢钠进行姜脯护色。
Abstract:One kind of sulfur free color fixative combined citric acid,sodium chloride,ascorbic acid,phytic acid with hot was developed to solve the harm of sulfur color fixative.The results showed that the four kinds of reagent complex was better than separate use of the synergies of the various color protection agent,color fixative combination to get better color protection through orthogonal optimization experiments:0.7%citric acid+1.5%sodium chloride+0.2%phytic acid+0.5%ascorbic acid under the condition of 100℃for 15 min,ginger pulp L*value could reach 46.85.The effect of compound stabilizer.color-protecting color with 0.3%sodium bisulfite could be instead of sodium bisulfite to ginger pulp color.
