Sensory quality analysis of rice based on fuzzy sensory evaluation

Fuzzy comprehensive evaluation was used to evaluate the sensory quality of rice, texture analyzer and color difference meter was used to evaluate the quality 7 different varieties of rice in this research.The results showed that the best the quality of rice was dalixiang, and the worst was 5 H25. The rice of 5 H25 had the best elasticity and chewiness.There were no significant differences among sticky hardness ratio, viscosity and elasticity of dalixixiang, jinmazhan and dalixiang, and dalixiang had the best texture with large value of sticky hardness ratio, viscosity and elasticity.There were significant differences in the color of different varieties of rice.The color of dalixiang and jinmazhan was the best by the comprehensive analysis of color value combined with sensory evaluation of rice color requirements.The fuzzy sensory evaluation was consistent with the appearance quality and texture characteristics, the comprehensive analysis showed that the sensory quality of dalixiang was the best, indicating that the fuzzy sensory evaluation can effectively evaluate the sensory quality of rice.
