Embodiment 1
[0027] A kind of processing method of pine nut shell of the present embodiment, comprises the steps:
[0028] (1) Dry the pine nuts, sterilize, break the shell to separate the shell kernel, then clean the pine nut shell, dry it, crush it to a particle size of 50-60 mesh, and perform supercritical extraction. The condition of supercritical extraction is that the temperature is 320K , the pressure is 18MPa, the flow rate of carbon dioxide is 2.2kg / min, the oil in the shell is extracted, and the remaining substances are added to cellulase and water, the activity of cellulase is 1.5 million u / g, and the cellulase in water The concentration is 0.13g / L, the mass ratio of pine nut shells to water is 1:4, the enzymolysis reaction is carried out under ultrasonic conditions, the ultrasonic power is 180W, the ultrasonic time is 40min, the enzymolysis temperature is 28°C, and the enzymolysis time is 3h;
[0029] (2) Recover the filtrate of the enzymolysis reaction, dry the filter residue...
