Food-grade activated carbon for improving serum cholesterol and preparation method of food-grade activated carbon

The invention discloses food-grade activated carbon for improving serum cholesterol, the preparation raw materials of the food-grade activated carbon comprise fruit shells, the preparation steps of the food-grade activated carbon comprise purification, rinsing, soaking and drying, pre-carbonization treatment and carbonization and activation treatment, and the mesh number of the food-grade activated carbon is 100-5000. The food-grade activated carbon provided by the invention can be combined with cholic acid, disturb intestinal liver circulation and promote cholesterol and cholic acid to be discharged from excrement, so that cholesterol in the liver is promoted to be degraded into cholic acid, and the food-grade activated carbon is harmless to gastrointestinal mucosa and can also effectively reduce serum cholesterol and improve liver lipid. According to the method for preparing the food-grade activated carbon, provided by the invention, in the carbonization and activation steps, after being carbonized, organic
