响应面法优化猪肉肠中食用胶复配配方研究

Optimization of the Compounding Formula of Food Gums in Pork Sausage by Response Surface Method

为了研究添加不同种类食用胶及其复配比例对猪肉肠出品率、保水率和感官品质的影响。本文以猪肉肠为试验对象,以亚麻籽胶、瓜尔豆胶和魔芋胶3种食用胶的复配比例为试验因素,在单因素实验基础之上,以出品率、保水率和感官评分为响应值,利用响应面(Box-Behnken)中心组合法进行三因素三水平的响应面优化猪肉肠中食用胶复配配方试验。结果表明,3种食用胶的最佳复配比例为:亚麻籽胶添加量0.50%、瓜尔豆胶添加量0.40%、魔芋胶添加量0.65%,所得猪肉肠出品率为98.97%、保水率为90.26%、感官评分为8.14,产品弹性较好,整体可接受度较高且优化所得结果准确可靠,可为猪肉肠加工工艺研究和品质提升提供数据支持和理论参考。

In order to study the effects of adding different kinds of edible gums and its compound ratio on the product rate,water retention rate and sensory quality of pork sausage products,and obtain the best edible gum compound ratio.The pork sausage was used as the experimental object,and the mixture ratio of flaxseed gum,guar gum and konjac gum were used as the experimental factors.On the basis of single-factor test,Box-Behnken central group method was used to conduct threefactor and three-level response surface analysis test with product rate,water retention rate and the sensory score as response values.The results showed that the best mix proportion of the three kinds of edible gum were:flaxseed gum 0.50%,guar gum 0.40%,konjac gum 0.65%,the pork sausage product rate was 98.97%,and water retention rate was at a rate of 90.26%and the sensory score was 8.14 as well as the product had good elasticity and high overall acceptable degree.Meanwhile,the optimization results were accurate and reliable test,and may provide data support and theoretical reference for pork sausage processing technology research and quality.
