Aiming at the serious problem of dietary fiber deficiency in modern diets,a preparation method of functional dietary fiber was proposed.The experiment first optimized the processing conditions of dietary fiber,and then studied the physical and chemical properties of dietary fiber.The experimental results showed that under the conditions of steam explosion steam pres-sure of 0.6 MPa and pressure maintaining time of 300 s,the highest SDF content of dietary fiber treated by high-energy nano ball mill was 9.86%,and the adsorption capacity of glucose was about 2.55 mg/g.After intragastric administration of diabetes mice,the blood sugar of the mice was reduced by 6.5%compared with that before intragastric administration,and the serum lipid concentration was also significantly reduced.It shows that the prepared dietary fiber has a good effect of lowering blood lipids and blood glucose,which can effectively delay and reduce postprandial blood glucose and maintain the balance and stability of postprandial blood glucose,and has a positive role in the control of diabetes.
