Abstract

The invention provides a preparation method of a corn stigma oral liquid capable of lowering blood glucose. The method comprises steps as follows: (1) superior corn stigmas are washed clean, dried in the sun and crushed, and corn stigma powder is obtained, added to deionized water and subjected to enzymolysis by compound enzyme at 50-70 DEG C with the PH ranging from 4 to 6 for 3-6 h; (2) an enzymatic hydrolysate obtained in step (1) is heated to be boiled, kept at the constant temperature for 5-10 min for enzyme deactivation, cooled to the room temperature and centrifuged, and a clear corn stigma liquid is obtained; (3) the clear corn stigma liquid obtained in step (2) is poured into trichloromethane, subjected to ultrasonic treatment for 5-10 min and left to stand for layering, a supernatant is taken and freeze-fried for 24 h, and a corn stigma extract is obtained; (4) the corn stigma extract obtained in step (3), an emulsifier, sucrose, potassium sorbate and purified water are evenly mixed, and thus the corn stigma oral liquid capable of lowering blood glucose is obtained. The prepared corn stigma oral liquid has high polysaccharide and flavonoid content, has an obvious blood glucose lowering effect, has no side effects and is suitable to be taken by patients for a long time.

Description

Technical field [0001] The invention belongs to the technical field of food health care, and specifically relates to a preparation method of a corn silk oral liquid for lowering blood sugar. Background technique [0002] Corn is one of the most widely distributed food crops in the world, and its planting area is second only to wheat and rice. The US's corn production accounts for about half of the world's output, and it is the most important food crop. China's annual corn production ranks second in the world and is widely distributed. It is one of the main foods for the people in the mountainous areas of northern and southwestern China and other dry valley areas. . Maize silk is the style and stigma of maize. The earliest medicinal records are found in "Wood grass in South Yunnan" in 1476. It is a common medicinal species 11l included in the "Medicinal Material Standards of the Ministry of Health of the People's Republic of China" 1985 (Part 1). , Antibacterial, hypolipidemic, ...
