Embodiment 1

[0037] The invention provides a hypoglycemic solid drink, which is made of the following raw materials in parts 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, said sturgeon protein peptide powder is made by the method comprising the following steps:

[0039] (1) Take fresh sturgeon skin to manually remove fat and fish meat, wash with distilled water, cut the cleaned sturgeon skin into small pieces of 5 mm × 5 mm, soak it in 2% acetic acid solution for 2 hours to further remove the remaining residue on the sturgeon skin The meat and fat are softened sturgeon skin, and the softened sturgeon skin is crushed with a blender (water:sturgeon skin=2:1), and poured into a container for steaming in a water bath to obtain a crude sturgeon protein extract;

[0040] (2) Adjust the pH value of the crude sturgeon protein extract to 8.0, hydrolyze it with alkalin...

Embodiment 2

[0045] The invention provides a hypoglycemic solid drink, which is made of the following raw materials in parts 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, said sturgeon protein peptide powder is made by the method comprising the following steps:

[0047] (1) Take fresh sturgeon skin to manually remove fat and fish meat, wash with distilled water, cut the cleaned sturgeon skin into small pieces of 4 mm × 4 mm, soak it in 2% acetic acid solution for 2 hours to further remove the remaining residue on the sturgeon skin The meat and fat are softened sturgeon skin, and the softened sturgeon skin is crushed with a blender (water:sturgeon skin=2:1), and poured into a container for steaming in a water bath to obtain a crude sturgeon protein extract;

[0048] (2) Adjust the pH value of the crude sturgeon protein extract to 8.0, hydrolyze it with alkaline...

Embodiment 3

[0053] The invention provides a hypoglycemic solid drink, which is made of the following raw materials in parts 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, said sturgeon protein peptide powder is made by the method comprising the following steps:

[0055] (1) Take fresh sturgeon skin to manually remove fat and fish meat, wash with distilled water, cut the cleaned sturgeon skin into small pieces of 6 mm × 6 mm, soak in 2% acetic acid solution for 2 hours to further remove the remaining residue on the sturgeon skin The meat and fat are softened sturgeon skin, and the softened sturgeon skin is crushed with a blender (water:sturgeon skin=2:1), and poured into a container for steaming in a water bath to obtain a crude sturgeon protein extract;

[0056] (2) Adjust the pH value of the crude sturgeon protein extract to 7.5, hydrolyze it with alkaline pro...

Abstract

The invention relates to the technical field of aquatic product processing and health product development, and especially relates to sturgeon protein peptide powder, and a preparation method and applications thereof. The preparation method includes the following steps: (1) performing pre-processing on sturgeon skins to obtain a sturgeon protein crude extract; and (2) adjusting the pH value of thesturgeon protein crude extract to 7.5-8.5, and performing enzymatic hydrolysis reaction under the action of alkaline protease, wherein the mass percentage of the alkaline protease and the sturgeon protein crude extract is 1.5-3%. The sturgeon protein peptide powder prepared through the method is rich in dipeptidyl peptidase-4 inhibitor, the inhibitory activity of the sturgeon protein peptide powder is greater than 62%, and the sturgeon protein peptide powder has the auxiliary hypoglycemic effect for people at all stages of diabetes history. A hypoglycemic solid beverage including the sturgeonprotein peptide powder is also provided. The raw materials of the solid beverage are from natural animals and plants, so that the solid beverage can be directly drunk for a long time; the toxic and side effects of traditional drugs can be avoided, so that the solid beverage is safe and reliable.

Description

technical field [0001] 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. Background technique [0002] At present, diabetes characterized by chronic hyperglycemia caused by defective insulin secretion is a serious threat to people's life and health. The emergence of adverse drug reactions such as diabetes has greatly limited 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 requirements. Aquatic collagen, such as fish collagen, is gradually becoming the main source of natural collagen. Sturgeon is one of the existing freshwater f...
