Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, make full use of fish resources, and solve the problem of serious waste of nutrients, the present invention provides a preparation method of marine fish collagen oligopeptide powder. Although acid-base is used to adjust the pH value during the preparation process, But it will not affect the processing quality of the product. At the same time, it can effectively remove the fish skin's own fishy smell and heavy metals, and obtain small-molecule collagen oligopeptide powder with high collagen content and concentrated molecular weight.

Embodiment 1

[0043] Marine fish collagen oligopeptide powder is prepared according to the following steps:

[0044] (1) Cleaning: Use food grade 0.1%-0.3% food grade sodium hydroxide and salt to wash the fish skin for 2-4 hours according to the ratio of material to liquid ratio of 1:3, drain the water, and then wash it with tap water for about 8 times , wash until the water is translucent and colorless, and the pH is around 9, set aside;

[0045] (2) Gel extraction: After feeding, add high-temperature water according to the production instructions, adjust the pH to 6, and extract the gel at 75°C;

[0046] (3) Filtration and standing: filter the material liquid after the rubber extraction through a triangular filter sieve and then put it in the clarification tank for 2-4 hours, and then discharge and filter after stratification;

[0047] (4) Cotton cake filtration: the supernatant is filtered through a cotton cake filter, the entire filtration pressure is controlled at 0.2MPa, and the turb...

Embodiment 2

[0059] As a preferred solution, the marine fish collagen oligopeptide powder of the present invention is prepared according to the following steps:

[0060] (1) Cleaning: Use food grade 0.1%-0.3% food grade sodium hydroxide and salt to wash the fish skin for 2-4 hours according to the ratio of material to liquid ratio of 1:3, drain the water, and then wash it with tap water for about 8 times , wash until the water is translucent and colorless, and the pH is around 9, set aside;

[0061] (2) Gel extraction: After feeding, add high-temperature water according to the production instructions, adjust the pH to 6, and extract the gel at 75°C;

[0062] (3) Filtration and standing: filter the material liquid after the rubber extraction through a triangular filter sieve and then put it in the clarification tank for 2-4 hours, and then discharge and filter after stratification;

[0063] (4) Cotton cake filtration: the supernatant is filtered through a cotton cake filter, the entire fil...

Abstract

The invention provides a preparation method of oligopeptide powder of marine-fish collagen and application thereof. The preparation method comprises the following steps: adopting marine-fish skin as araw material, and adopting a method of mixing acidolysis and enzymolysis to prepare the oligopeptide powder with the oligopeptide content being higher than 96%. The oligopeptide powder can be widelyapplied to the fields of functional food and medicine industries such as the wine industry, the beverage industry, the seasoning industry, the health-care industry, the oral liquid, tablets and capsules.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a preparation method and application of marine fish collagen oligopeptide powder. Background technique [0002] Collagen has a wide molecular weight distribution, and collagen with a large molecular weight is difficult to absorb and utilize by the human body, so it is suitable for use as stabilizers, emulsifiers, clarifiers, etc. Collagen with a small molecular weight is generally composed of 10 to 100 amino acids, and its molecular weight is less than 1000 Daltons. This collagen is also called collagen peptide. Because of its small molecular weight, it is easily absorbed by the human body and is used in nutritional and health food. More, there is a higher demand for the collagen market. Among collagens with relatively small molecular weight, marine fish collagen oligopeptide is a common deep-processed product of marine fish collagen, which is refined and processed from ...
