The extraction process of walnut protein extracted from walnut and the physicochemical properties of walnut protein were studied in this paper.The effects of extraction time,grain size of walnut meal powder,water content Wo,electrolyte(KCL)concentration,liquid ratio and pH on the extraction rate of walnut protein were analyzed by the first step single factor test.The second step three factor three level response surface test was conducted to study the effect of pH value,the amount of walnut meal addition and water content Wo on the reverse micelle system,and optimize the extraction conditions of the reverse micelle system.The optimum extraction conditions were as follows: Walnut meal powder added 16.37%,pH=8.25,water content = 19.34%,walnut meal 100 mesh,KCL concentration 0.1mol/L When the extraction time was 30 min,the extraction rate of walnut protein was highest,which was(93.79 + 0.80)%.Compared with the traditional extraction method,the extraction rate of walnut protein was higher.On this basis,walnut protein was collected and its physicochemical properties were collected,including the water absorption,the milk property of walnut protein,the emulsification stability of walnut protein and the starting of walnut protein.Foam stability and foam stability.
