[0016] The present invention will be further described below:
[0017] The present invention comprises the following steps:
[0018] Step 1. Take the walnut kernels and use a hydraulic oil press to squeeze out the oil. When the pressure is 4 MPa, the oil starts to come out; when the pressure rises to 10 MPa, there is very little walnut oil flowing out, and the pressure can be released to discharge the material;
[0019] Step 2, put the walnut cake into the extraction tank and water at a ratio of 1:9, and extract at 100°C under normal pressure for 2 hours;
[0020] Step 3: Use an oil-water analyzer to separate the residual oil. The extracted soup is transferred to the enzymatic hydrolysis tank;
[0021] Step 4: Cool the above extract to 55°C, add 0.5 g of cellulase and 0.25 g of pectinase to hydrolyze for 2 hours at pH 4.5, adjust the pH to 6.5, add 0.25 g of neutral protease and 0.25 g of alkaline protease and continue stirring for 2 hours. Maintain 55°C;
[0022] Step 5. ...
