Abstract：With defatted walnut meal as the raw material，the process formula of low-fat walnut sauce is optimized to develop a kind of low-fat walnut sauce product. Through the weight analysis of the color，flavor，texture and taste of low-fat walnut sauce，a fuzzy mathematics sensory evaluation model for low-fat walnut sauce is established. The process formula of low-fat walnut sauce is optimized using random centroid optimization （RCO） method，the efects of the addition amount of sodium alginate， monoglyceride，beeswax，walnut meal and water on the sensory quality of low-fat walnut sauce are explored，and its quality characteristics are analyzed.The results show that the optimal processformula of low-fat walnut sauce is sodium alginate addition amount of 1.1% ，beeswax addition amount of 0.6% ， monoglyceride addition amount of 0.3% ，walnut meal addition amount of 18% and water addition amount of 80% . The sensory score of low-fat walnut sauce made by this process is 9o.1O points. Compared with commerciallyavailable walnut sauce and walnut sauce produced by enterprises，its taste is the best， and the fat content （3.78g/100g） is significantly lower than that of commercially available products （ ΔP<0.05 ） Its texture properties （hardness is 2.15N ，gumminess is 1.46N ，cohesiveness is O.33，adhesiveness is 1.53mJ ） are consistent with those of commerciall available walnut sauce. This study has provided theoretical guidance for the effective utilization of walnut meal and the production of low-fat walnut sauce.
