摘要
为了获得口感及风味更佳的糟辣椒产品,本试验对传统糟辣椒的制作配方及工艺进行改进,以有机酸、挥发性风味物质及各项理化指标为考察指标,分别检测了传统工艺制作的传统糟辣椒、新工艺配方制作的风味糟辣椒中的风味物质。结果表明,与传统糟辣椒相比,风味糟辣椒还原糖含量增加了2. 978 0 g/kg,氨基酸态氮含量增加了0. 03 g/kg,总有机酸含量增加了1. 247 1 g/kg,对酸感有明显改善的乳酸、苹果酸、柠檬酸在风味糟辣椒中含量均升高,改善了传统糟辣椒酸感刺激、有涩味的口感,使风味糟辣椒的酸味更加柔和爽口,滋味评分升高;其次,风味糟辣椒多检出了12种风味化合物,对风味贡献率高的醇类、酯类物质种类、含量均增大,使得风味糟辣椒香气更浓郁,风味及感官评分均显著增大。新工艺配方制作的风味糟辣椒具有更高的商品价值,可为云贵地区的糟辣椒行业发展起到提质增效的参考示范作用。
In order to obtain Zao-peppers with better tastes and flavour,this experiment improved the formulation and technology used for producing traditional Zao-peppers. This experiment measured volatile compounds,organic acids,and physicochemical properties of two kinds of Zao-peppers. The results showed that in comparison to traditional Zao-peppers,the contents of reducing sugar,amino acid nitrogen,and total organic acids in flavored Zao-peppers increased by 2. 978 0 g/kg,0. 03 g/kg,and 1. 241 7 g/kg,respectively. The contents of lactic acid,malic acid,and citric acid in flavored Zao-peppers increased,which modified the stimulating,sour,and astringent tastes of traditional Zao-peppers. In other words,the sourness of flavored Zao-peppers was more gentle and refreshing,with an increased taste score. Secondly,more than twelve kinds of flavor compounds were detected in flavored Zao-peppers.The flavor and sensory scores of flavored Zao-peppers increased,as the types and contents of flavor-contributing alcohols and esters increased,which made flavored Zao-peppers more fragrant. The flavored Zao-peppers produced by the new processing formula has higher commodity value. Therefore,this study can be a reference for developing Zao-peppers industries in Yunnan and Guizhou provinces.
