Embodiment 1

[0037] The present invention provides a hypoglycemic solid beverage, which is prepared from the following raw materials by weight: 9.0 parts of sturgeon protein peptide powder, 5.7 parts of L-arabinose, 38.8 parts of black tea powder, and 46.5 parts of fruit and vegetable powder;

[0038] Wherein, the sturgeon protein peptide powder is prepared by a method comprising the following steps:

[0039] (1) Take fresh sturgeon skin to remove fat and flesh manually, wash with distilled water, cut the cleaned sturgeon skin into 5mm × 5mm pieces, soak in 2% acetic acid solution for 2h to further remove residual sturgeon skin Meat and fat, get softened sturgeon skin, use a mixer to break the softened sturgeon skin (water: sturgeon skin = 2:1), pour it into a container for steaming in a water bath to obtain a crude sturgeon protein extract;

[0040] (2) The pH value of the sturgeon protein crude extract was adjusted to 8.0, enzymatically hydrolyzed with alkaline protease at 55°C for 50 mi...

Embodiment 2

[0045] The invention provides a hypoglycemic solid beverage, which is prepared from the following raw materials by weight: 10.0 parts of sturgeon protein peptide powder, 6.4 parts of L-arabinose, 37.6 parts of black tea powder, and 46 parts of fruit and vegetable powder;

[0046] Wherein, the sturgeon protein peptide powder is prepared by a method comprising the following steps:

[0047] (1) Take fresh sturgeon skin to remove fat and flesh manually, wash with distilled water, cut the cleaned sturgeon skin into 4mm × 4mm pieces, soak in 2% acetic acid solution for 2h to further remove residual sturgeon skin Meat and fat, get softened sturgeon skin, use a mixer to break the softened sturgeon skin (water: sturgeon skin = 2:1), pour it into a container for steaming in a water bath to obtain a crude sturgeon protein extract;

[0048] (2) The pH value of the sturgeon protein crude extract was adjusted to 8.0, enzymatically hydrolyzed with alkaline protease at 58° C. for 60 min, inac...

Embodiment 3

[0053] The invention provides a hypoglycemic solid beverage, which is prepared from the following raw materials by weight: 8.0 parts of sturgeon protein peptide powder, 6.4 parts of L-arabinose, 37.6 parts of black tea powder, and 48 parts of fruit and vegetable powder;

[0054] Wherein, the sturgeon protein peptide powder is prepared by a method comprising the following steps:

Abstract

The invention relates to the technical field of aquatic product processing and the technical field of health product development, in particular to a sturgeon protein peptide powder and its preparation method and application. The preparation method of the sturgeon protein peptide powder comprises: (1) pre-treating the sturgeon skin to obtain a sturgeon protein crude extract; (2) adjusting the pH value of the sturgeon protein crude extract to 7.5-8.5 , carrying out the enzymolysis reaction under the action of alkaline protease; the mass percentage of the alkaline protease and the crude sturgeon protein extract is 1.5-3%. The sturgeon protein peptide powder prepared by the above method is rich in dipeptidyl peptidase-4 inhibitor, and its inhibitory activity is greater than 62%. The role of blood sugar. The present invention also provides a hypoglycemic solid beverage containing the above-mentioned sturgeon protein peptide powder. The raw materials of the hypoglycemic solid beverage are all from natural animals and plants, can be drunk directly and for a long time, avoid the toxic and side effects of traditional medicines, and are safe and reliable.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing and the technical field of health care product development, in particular to a sturgeon protein peptide powder and a preparation method and application thereof. Background technique [0002] At present, diabetes characterized by chronic hyperglycemia caused by insulin secretion defect is a serious threat to people's life and health. The emergence of adverse drug reactions such as these greatly limits the clinical application of traditional hypoglycemic drugs. Therefore, there is an urgent need to develop new hypoglycemic drugs or auxiliary hypoglycemic functional products. [0003] In recent years, mammalian skin and Achilles tendon tissue, as the main source of natural collagen, have been unable to meet the application needs. Aquatic collagen, such as fish collagen, is gradually becoming the main source of natural collagen. Sturgeon is one of the existing freshwater fish wit...
