Embodiment 1

[0021] Embodiment 1: This embodiment provides a fresh-keeping agent for fish, including 76.0 kg of sodium percarbonate, 2.0 kg of vitamin C, 2.0 kg of methionine, 2.0 kg of lysine, 10.0 kg of polyhydroxyalkanoate, and 11 kg of stearic acid.

[0022] According to the following steps, the preservative for fish component of Example 1 is prepared into a preservative for fish:

[0023] S1. Preparation of sodium percarbonate granules: Heat 9kg of stearic acid to 80-90°C to dissolve it into a stearic acid solution, then put sodium percarbonate into a high-efficiency wet granulator, then add the stearic acid solution, and stir Cool to 25-30°C during the process, then granulate with a particle swing granulator, granulate with a 20-mesh sieve, and obtain sodium percarbonate granules;

[0024] S2. Preparation of mixed granules: Heat and dissolve 2kg of stearic acid to 80-90°C to decompose into a stearic acid solution, then put vitamin C, methionine, lysine, and polyhydroxyalkanoate into ...

Embodiment 2

[0027] Embodiment 2: This embodiment provides a kind of fresh-keeping agent for fish, comprises sodium percarbonate 80.0kg, vitamin C 3.0kg, arginine 1.5kg, tryptophan 1.5kg, polyhydroxyalkanoate 12.0kg, glycerol stearate Ester 12kg.

[0028] According to the following steps, the preservative for fish component of embodiment 2 is prepared into a preservative for fish:

[0029] S1. Preparation of sodium percarbonate granules: Heat 10kg of glyceryl stearate to 85-90°C to dissolve glyceryl stearate solution, then put sodium percarbonate into a high-efficiency wet granulator, and then add stearic acid The glyceride solution is cooled to 25-30°C during the stirring process, then granulated with a granulator swinging granulator, and granulated with a 20-mesh sieve to obtain sodium percarbonate granules;

[0030] S2. Preparation of mixed granules: heat 2kg of glyceryl stearate to 85-90°C to dissolve glyceryl stearate solution, then put vitamin C, arginine, tryptophan and polyhydroxy...

Abstract

The invention relates to the technical field of fresh-keeping agents for fish, and discloses a fresh-keeping agent for fish and a preparation method of the fresh-keeping agent. The preservative comprises 75-85 parts of sodium percarbonate, 1-5 parts of vitamin C, 1-5 parts of amino acid, 8-15 parts of polyhydroxyalkanoate and 5-15 parts of a waxy material. Sodium percarbonate provides oxygen for the fish in the transportation process, vitamin C and amino acid provide nutritional ingredients, and it is ensured that the fish can supplement nutrition loss in time in the transportation process. The polyhydroxyalkanoate is used as a microbial polymer material, has the effects of inhibiting bacterial pathogens and improving the antibacterial ability of fishes, and reduces the irritability. According to the fish preservative disclosed by the invention, fishes can survive for 2-3 days only by adding a proper amount of the fish preservative, so that the death quantity of the fishes in the transportation process is reduced, and the transportation cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping agents for fish, in particular to a fresh-keeping agent for fish and a preparation method thereof. Background technique [0002] During the transportation and sales of live fish, there has always been a problem of freshness preservation. As a result, it is necessary to use an aerator to increase oxygen during transportation from the fish pond to the market, so as to avoid the problem of dead fish. However, the use of an aerator requires a dedicated power supply for the aerator, which cannot be realized by a general transport vehicle, which seriously affects the freedom of fish ponds to sell fish independently. And in the process of market sales, also because of the cost of the power source of the aerator, only relying on the viability of the fish itself can not avoid dead fish, resulting in inability to sell or low sales profit. [0003] Therefore, if there is a drug that can provide oxygen...
