基于模糊数学和响应面法的超高压嫩化河蚌肉的感官评价

The sensory evaluation of mussel meat tenderization treated by ultra-high pressure based on fuzzy mathematics and response surface method

为提升河蚌肉食用品质,利用超高压技术对蚌肉进行嫩化处理。选取色泽、黏度、弹性和气味为感官评价因素,利用层次分析法确定评价因素的权重,建立模糊感官综合评分体系,并以压力强度、CaCl_2浓度和保压时间为实验因素,以超高压处理后的河蚌肉感官评价的模糊综合评分Y为响应值,进行3因素3水平Box-Behnken响应面实验设计,并对模型进行优化。试验结果表明,在压力强度364.51 MPa、CaCl_2浓度0.28 mol/L、保压时间14.55 min条件下河蚌肉的综合评分最优为1.034。模糊数学和响应面法相结合用于超高压嫩化河蚌肉的工艺切实可行,且重复性好。

In order to improve the taste of mussel meat, tenderization was carried out by ultra-high pressure treat- ment. Color, viscosity, elasticity and smell were selected as the sensory evaluation factors. To establish fuzzy sensory integrated scoring system, analytic hierarchy process was used to determine the weight of evaluation factors. The pres- sure intensity, CaCl2 concentration and holding time were chosen as the experimental factors, the response value was the fuzzy comprehensive score of Y, which was the sensory evaluation of mussel meat tenderization treated by ultra- high pressure. Three-factor and three level Box-Behnken response surface experiment was designed and optimized. The test results showed that under the condition of pressure intensity 364.51 MPa, CaCl2 concentration 0.28 mol/L and holding time 14.55 min, the best comprehensive score of the mussel meat wasl. 034. The application of the com- bining fuzzy mathematics and response surface method in the process of ultra-high pressure tenderization of mussel meat is feasible and repeatable.
