The traditional walnut powder is used for removing bitter taste, is treated by NaOH solution, needs to be repeatedly rinsed, is easy to have reagent residues, consumes manpower and material resources, adopts an enzymolysis method to remove walnut kernel peel, has low equipment requirement and good effect, and has the peel dragging rate of finished products of over 99.5 percent. Specifically, walnut kernels, water, pectinase and cellulase are mixed and then subjected to enzymolysis for 10min to 30min at the temperature of 55 ℃ to 60 ℃ and under the condition that the pH value is 7 to 9, and the walnut kernels with hulls removed are obtained after filtration; the mass of the water is 2-3 times of that of the walnut kernel, the total mass of the pectinase and the cellulase is 0.7-1.3 percent of that of the walnut kernel, and the mass ratio of the pectinase to the cellulase is (3-5) to 1.
In the general process of processing walnut powder, fat is removed in the squeezing process, the lower the fat content of the final product is, the higher the protein content of the product is, the higher the grade is, and the protein component can not be degraded in the high-temperature long-time heating process; however, the walnut kernel contains 15-20 g of protein per hundred g, the fat content is as high as 58g, 86% of fat in the walnut kernel is unsaturated fatty acid, particularly rich omega-3 fatty acid, so that the probability of suffering from depression, Attention Deficit Hyperactivity Disorder (ADHD), cancer, senile dementia and the like can be reduced, the walnut kernel has a great health-care effect, the problem that the walnut powder is required to retain the fat content as high as the fat content is another key problem solved by the invention is that the fat is easily subjected to oxidative decomposition due to the action of high temperature and high humidity in the drying process, and meanwhile, vitamins in the walnut kernel are more easily subjected to oxidative degradation. At present, a great deal of research on lipid oxidative degradation shows that the long-term action of high temperature and high humidity can promote the oxidative decomposition of fat, and because the walnut powder is processed by adopting a device for heating and pre-curing simultaneously in the drying process, the active ingredients including fat and protein are reserved, the processing process is safe and transparent, the health-care performance of the product is good, the walnut powder can be directly prepared by boiling water or prepared by adding other nutritional ingredients such as milk powder and the like, and the walnut powder is suitable for direct processing and sale in hospitals, office buildings and the like, and has wide market prospect.
