Problems solved by technology

However, the above-mentioned various drugs have their limitations. For example, biguanide hypoglycemic drugs can cause greater damage to the stomach and cause indigestion; sulfonylureas may cause leukopenia; Intestinal reactions, specifically manifested as abdominal distension, stomach distension, burning pain in the upper abdomen, diarrhea or constipation; insulin sensitizers may cause water retention
[0006] The most commonly used hypolipidemic drugs are HMG-CoA reductase inhibitors, specifically lovastatin, simvastatin, pravastatin, mevastatin, fluvastatin, atorvastatin, cerivastatin and Rovastatin, etc. However, statins are likely to cause increased liver enzymes, which may cause changes in liver function, and some patients have symptoms of muscle pain after taking the drug, and some even cause muscle lysis
[0007] In summary, there is currently no reliable and satisfactory treatment for lowering blood sugar and blood lipids.

Abstract

The invention relates to an application of a seaweed polypeptide in preparing a health-care product for reducing blood fat and blood sugar as well as a beverage containing the polypeptide for reducing the blood fat and the blood sugar. The seaweed polypeptide is prepared by the following steps of: milling a mixture of immersed porphyra haitanensis and water through a colloid mill to obtain porphyra haitanensis slurry; adopting AS.1398 neutral protease to carry out enzymolysis on the porphyra haitanensis slurry for 5-10 hours under the conditions that the temperature is 45-55 DEG C, the pH (Potential of Hydrogen) is 7.2-7.8, the enzyme adding amount E/S is 8000-12000 U/g and the weight/volume ratio concentration of a substrate is 3-7%, so as to obtain an enzymolysis solution; centrifuging the enzymolysis solution and collecting liquid supernatant; and carrying out ultra-filtering separation on the liquid supernatant to obtain an active component with the molecular weight of less than 10000 Da. An animal experiment shows that agars are subjected to biological enzymolysis to obtain the seaweed polypeptide which has the obvious effects of reducing the blood fat, the blood sugar and blood pressure; and after the seaweed polypeptide is taken for a long period, the weight can be prevented from too fast increase and the happening possibility of arteriosclerosis can be reduced.

Description

[0001] technical field [0002] The present invention relates to the medical use of the polypeptide and a beverage containing the polypeptide, in particular to a seaweed polypeptide with the function of lowering blood fat and blood sugar and a beverage containing the polypeptide for lowering blood fat and blood sugar. Background technique [0003] Seaweed belongs to lower plants and mainly grows in shallow sea areas. my country has a long coastline, a large area of ​​shallow seas, and a rich variety of seaweeds. Among them, seaweeds with economic value are mainly divided into three categories: green algae, brown algae and red algae. At present, the commercial seaweeds that have been artificially cultured mainly include: kelp, wakame and hijiki belonging to brown algae; algae, Porphyra variegata, asparagus, gracilaria, red cabbage and kylin belonging to red algae dishes etc. [0004] However, since the development of seaweed industry in my country is in its infancy, its util...
