Problems solved by technology

[0003] Lotus seed husk is a by-product of lotus seed processing and production. At present, the annual output of lotus husk in my country can reach tens of thousands of tons. Because of its hard texture and inedibility, it can only be discarded in large quantities in addition to being used as firewood in a small amount. Let the fields rot naturally and pollute the environment

Abstract

The invention discloses a lotus seed hull extract with an effect of lowering blood glucose. The lotus seed hull extract is characterized by being prepared by a following method: firstly, uniformly mixing and stirring lotus seed hull powder and water or a hydrophilic organic solvent; then, performing ultrasonic extraction and freeze drying on the mixture. The method has the advantages that a side product produced in agricultural product processing is treated, the environment pollution is lowered, waste is changed into treasure, and an active component with the effect of lowering the blood glucose applicable to functional foods is obtained.

Description

technical field [0001] The invention relates to an active ingredient, in particular to a lotus seed shell extract with hypoglycemic effect and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the influence of factors such as diet and environment makes the incidence of diabetes extremely high. Diabetes is an endocrine system disease with a complicated pathogenesis. It often causes sugar, fat and protein metabolism disorders, and is characterized by high blood sugar and urine sugar. [0003] Lotus seed husk is a by-product of lotus seed processing and production. At present, the annual output of lotus husk in my country can reach tens of thousands of tons. Because of its hard texture and inedibility, it can only be discarded in large quantities in addition to being used as firewood in a small amount. The fields are allowed to rot naturally, causing pollution to the environment. [0004] The inventors have determine...
