Problems solved by technology

[0003] The traditional preparation process of fish protein peptides is to clean the fresh fish, remove the viscera, use the fish meat to directly homogenate and enzymatically hydrolyze, and then obtain it through solid-liquid separation, membrane separation, concentration and drying. The preparation process The obtained products often have a strong fishy smell, which will not only affect consumers' acceptance of products, but also significantly reduce their economic benefits
[0004] In order to solve the problem of fishy smell of fish protein peptide products,

Embodiment 1

[0034] In this embodiment, a method for preparing marine fish protein peptides includes the following steps:

[0035] (1) Rinse:

[0036] Remove the head and internal organs of the fresh ocean fish, take the fish meat, rinse the fish with cold water at 4°C, the water consumption for each rinse is 1:1 (w / w), after each rinse, add water and stir for 2 minutes, let it stand for 3 minutes and then pour Take out the supernatant and collect the precipitated fish. The rinsing procedure is repeated 3 times, and the rinsing supernatant can be concentrated into seafood seasoning;

[0037] (2) Ozone sterilization:

[0038] Step (1) The rinsed fish meat is added with water at a ratio of 1:0.5 (w / w), then homogenized into a fish slurry with a colloid mill, and stirred evenly to pass in ozone to keep the ozone concentration of the fish slurry at 0.4 ppm and sterilize for 3 minutes;

[0039] (3) Enzymatic hydrolysis:

[0040] In the fish slurry treated in step (2), add ginger juice and gallocatechin a...

Embodiment 2

[0045] In this embodiment, a method for preparing marine fish protein peptides includes the following steps:

[0046] (1) Rinse:

[0047] Remove the head and internal organs of the fresh sea fish, take the fish meat, rinse the fish meat with cold water at 0℃, the water consumption for each rinse is 1:3 (w / w), after each rinse add water, stir for 1 min, let stand for 2 min before pour Take out the supernatant, collect the precipitated fish, and repeat the rinsing procedure 4 times;

[0048] (2) Ozone sterilization:

[0049] Step (1) The rinsed fish meat is added with water at a ratio of 1:0.3 (w / w), and then homogenized into a fish slurry with a colloid mill, stirred evenly and introduced into ozone, keeping the ozone concentration of the fish slurry at 0.3 ppm, and sterilizing for 5 minutes;

[0050] (3) Enzymatic hydrolysis:

[0051] In the fish slurry treated in step (2), add ginger juice and gallocatechin according to the volume of the fish slurry at 0.1% (w / v) and 0.2% (w / v) respect...

Abstract

The invention relates to ocean fish protein peptide and a preparation method thereof. The preparation method includes the following steps that (1) fresh ocean fish flesh is taken and rinsed with water to make fish paste through water addition; (2) ozone is injected into the fish paste for sterilization; (3) ginger juice and nutgall catechin are added into the fish paste, and then the mixture is subjected to enzymolysis to obtain enzymatic hydrolysate; (4) perlite is added into the enzymatic hydrolysate and stirred sufficiently, then filtering is performed, filtrate is taken to be subjected to centrifugal separation, and supernatant is taken to be subjected to follow-up concentrating and drying to obtain ocean fish protein peptide. By the utilization of the preparation method, substances of a stinking smell are effectively prevented from forming in the preparation process of the ocean fish protein peptide, the prepared ocean fish protein peptide product is stable in nature, will hardly generate the stinking smell in the storing process and is high in economic value, and the application field and range of the ocean fish protein peptide are expanded.

Description

Technical field [0001] The invention relates to the field of marine biological products and biotechnology processing, in particular to a marine fish protein peptide and a preparation method thereof. Background technique [0002] Marine fish resources are abundant, and the protein peptides prepared from them are an important functional base material, which is not only rich in nutrition, but also has various health care functions such as anti-tumor, anti-aging, enhancing body immunity, and anti-oxidation. At present, there is an increasing demand for marine fish protein peptides in the fields of food, health products, biomedicine and functional cosmetics. [0003] The traditional preparation process of fish protein peptides is to clean the fresh fish and remove the internal organs, and then use the fish meat to directly homogenize and enzymatically, and then obtain through the steps of solid-liquid separation, membrane separation, concentration and drying. The preparation process Th...
