摘要: 随着美拉德反应的日趋成熟，越来越多人使用美拉德反应制造新型调品，本毕业论文通过美拉德反应制备一种新的鸡肉香精调品。应用人工感官评价、电子鼻、电子舌技术对商业鸡精调品进行区分分析。通过单因素和响应面试验确定美拉德反应配方为：酶解液24g、半胱氨酸0.05g、甘氨酸0.2g、VC 0.05g、VB 0.025g、木糖0.75g、果葡糖浆0.75g、鸡油1.5g、盐0.1g、大蒜粉0.05g、桂皮粉0.075g、洋葱粉0.05g、八角粉0.05g以及生姜粉0.1g；美拉德反应条件为反应温度为105℃，反应时间为0.77h，反应体系初始pH为5.8，反应得到的鸡肉香精调品鸡肉特征浓郁，香气柔和。试验结果表明电子鼻、电子舌具有辨别区分不同调品的能力，可以用于调品的区别分析，为企业控制鸡精调品的品质提供理论基础。20363

Application of electronic sensory analysis on chicken flavor seasonings by maillard reaction
Abstract: Maillard reaction had been widely used to make the new seasonings. Maillard reaction was used to prepare a new kind of chicken essence flavor. The difference of commercial chicken seasonings was distinguished using sensory evaluation, electronic nose, electronic tongue compared with principal component analysis, cluster analysis and discriminant factor analysis. According to single factor and response surface analysis experiment, the maillard reaction experiment formula was enzymatic hydrolysate 24g, cysteine 0.05g, glycine 0.2g, VC 0.05g, VB 0.025g, xylose 0.75g, fructose syrup 0.75g, chicken fat 1.5g, salt 0.1g, garlic powder 0.05g, cinnamon powder 0.075g, onion powder 0.05g, star anise powder 0.05g and ginger powder 0.1g; The optimal condition of maillard reaction was the reaction temperature 105 ℃, the reaction time 0.75 h, pH 5.8. The chicken flavor obtained from maillard reaction had rich and gentle aroma. The results showed that the electronic nose and electronic tongue can be used to distinguish different seasoning. Electronic nose and electronic tongue can be used for quality analysis of chicken seasonings，this would provide theoretical basis for company to control the quality of chicken seasonings.
