Problems solved by technology

[0004] The object of the present invention is to provide a kind of preparation method of tuna protein peptide, in order to solve the existing protein peptide that proposes in the above-mentioned background technology and mostly extract from the plant, but in fact the protein peptide that extracts from the fish is also comparatively abundant, and quality and The curative effect is much stronger than that extracted from plants, but there is no good preparation method, which makes the production more difficult, the production cost is higher, and the yield is not high. At the same time, it is difficult to be used in other fields such as medical treatment, which increases the difficulty of work. brought about economic losses

Embodiment 1

[0021] see figure 1 , the present invention provides a technical solution: a preparation method of tuna protein peptide, comprising the following steps, the

[0022] Step 1: First choose fresh tuna skin as the raw material, then mix the fish skin with water at a ratio of 1:30, and then heat it to the boiling point in a sealed container so that the water temperature is always kept at 100 degrees Celsius. This process lasts for two After three hours, a mixed solution was obtained;

[0023] Step 2: Cool down the obtained mixed solution to 40-65 degrees Celsius, then add enzymes to the mixed solution, let it stand for one to two hours and then fully stir;

[0024] Step 3: Then add chymotrypsin and lipase to the mixed solution stirred in step 2, and stir for two to four hours for enzymolysis to obtain an enzymolysis solution;

[0025] Step 4: decolorize the enzymatic solution with activated carbon, filter to obtain a decolorized solution, and obtain collagen peptides after purifi...

Embodiment 2

[0032] A preparation method of tuna protein peptide, comprising the following steps, the

[0033] Step 1: First select fresh tuna skin as the raw material, then mix the fish skin with water at a ratio of 1:25, and then heat it to the boiling point in a sealed container so that the water temperature is always kept at 90-100 degrees Celsius. This process After maintaining for two hours, a mixed solution was obtained;

[0034] Step 2: Cool down the obtained mixed solution to 50 degrees Celsius, then add enzymes to the mixed solution, let it stand for one to two hours, and then fully stir;

[0035] Step 3: Then add chymotrypsin and lipase to the mixed solution stirred in step 2, and stir for three hours for enzymolysis to obtain an enzymolysis solution;

[0036] Step 4: decolorize the enzymatic solution with activated carbon, filter to obtain a decolorized solution, and obtain collagen peptides after purification and drying.

Embodiment 3

[0038] In the step 2, the stirring speed is 60 rpm, and the stirring time is 13 minutes; in the step 3, the stirring speed after adding chymotrypsin and lipase is 90 rpm, and the stirring time is 40 minutes .

[0039]The working principle and application process of the present invention: first select fresh tuna skin as raw material, then mix the fish skin and water according to the ratio of 1:30, then put it in a sealed container and heat it to the boiling point, so that the water temperature is always kept at 100 Celsius, the process is maintained for two to three hours to obtain a mixed solution; the obtained mixed solution is cooled to 40-65 degrees Celsius, then the enzyme is added to the mixed solution, and it is fully stirred after one to two hours; Add chymotrypsin and lipase to the mixed solution, stir and enzymolyze for two to four hours to obtain an enzymolyzed solution; decolorize and decolorize the enzymolyzed solution with activated carbon, filter to obtain a deco...

Abstract

The invention discloses a preparation method of tuna protein peptide. The method comprises the following steps of 1, firstly, selecting fresh tuna skin as raw materials, then, mixing the tuna skin andwater according to the ratio of 1:30, then, heating the mixture in a closed container to reach the boiling point, keeping the water temperature to 100 DEG C all the time, and in the process, obtaining a mixed solution after 2-3 h; 2, cooling the obtained mixed solution to 40-65 DEG C, then, adding an enzyme into the mixed solution, performing standing for 1-2 h, and then performing sufficient stirring; 3, the preparation method of the tuna protein peptide is high in yield, good in antibacterial activity and good in beautifying and skin moisturizing effect; meanwhile, the adopted raw materialscontain no hazard substances, no environment contamination is caused, the materials are wide in source, the preparation technology is simple, the product has the effects of maintaining beauty, keeping young, promoting cell growth and resisting aging, and the great important effect is brought into play for vital activity.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a preparation method of tuna protein peptide. Background technique [0002] Protein peptide is a pure natural nutrient extracted from animals and plants. It is also an important part of human cells. It is mainly composed of 2-10 amino acids and has a molecular weight below 3000. It plays an extremely important role in life activities. High blood pressure, anti-cholesterol, anti-thrombosis, enhancement of human immunity, etc., as well as diabetes have significant health care effects. [0003] Most of the existing protein peptides are extracted from plants, but in fact, the protein peptides extracted from fish are also relatively rich, and their quality and curative effect are much stronger than those extracted from plants, but there is no good preparation method, which makes the production difficult Larger, higher production cost, low yield, and difficult to use in other fields ...
