[0019] Pick out the chestnut shells without mildew, put them in an oven at 70°C, dry them, and crush them with a jet mill. The powder is a mixture of chestnut shell red coat and inner membrane; weigh 20g of chestnut shell powder, add 400mL of 50% Phosphate buffer solution, leaching in a water bath at 60°C for 2 hours, after cooling, filter, centrifuge, and suction filter the extract; add 350mL of 60% phosphate buffer solution to the above chestnut shell powder, and then add 10mg / g of acid-base The fibers were enzymolyzed in a water bath at 40°C for 100 minutes, and then heated in a water bath at 90°C for 5 minutes to inactivate the enzyme; put the above-mentioned mixed solution after inactivating the enzyme into a 500W ultrasonic wave, and the temperature was controlled at 50°C. The ultrasonic treatment time is 15 minutes; the ultrasonic extract is cooled, filtered and centrifuged, vacuum concentrated to a certain concentration with a rotary evaporator, and then subjected to hi...
