Embodiment 1

[0033] This embodiment provides a method for preparing a composition for reducing trimethylamine in live fish, comprising the following steps:

[0034] (1) prepare tea polyphenols:

[0035] (1) select green tea leaves to be washed 3 times first, then dried to a water content of 9%, and finally pulverized through a 50-mesh sieve to obtain tea powder;

[0036] (2) Mix the tea powder and ethanol with a concentration of 75wt.% in a weight ratio of 1:6, extract with ultrasonic waves of 100W power for 20min, and filter to obtain the extract after completion;

[0037] (3) Rotate the extract solution under vacuum conditions, concentrate to 1 / 4 of the original volume, then extract with chloroform, and discard the extraction phase after completion to obtain the dissolved phase;

[0038] (4) Dry the dissolved phase at 30°C under blast conditions to obtain tea polyphenols.

[0039] (II) Preparation of compositions for reducing trimethylamine in live fish:

[0040] (i) 22g of Lactobacil...

Embodiment 2

[0044] This embodiment provides a method for preparing a composition for reducing trimethylamine in live fish, comprising the following steps:

[0045] (1) prepare tea polyphenols:

[0046] (1) select green tea leaves to be washed twice first, then dried to a moisture content of 8%, and finally pulverized through an 80-mesh sieve to obtain tea powder;

[0047] (2) Mix the tea powder and ethanol with a concentration of 85wt.% at a weight ratio of 1:10, extract with ultrasonic waves of 200W power for 30min, and filter to obtain the extract after completion;

[0048] (3) Rotate the extract solution under vacuum conditions, concentrate to 1 / 3 of the original volume, then extract with chloroform, and discard the extraction phase after completion to obtain the dissolved phase;

[0049] (4) Dry the dissolved phase at 40°C under blast conditions to obtain tea polyphenols.

Abstract

The invention relates to a composition for reducing trimethylamine in living fish and a preparation method of the composition. The composition for reducing trimethylamine in the living fish comprisesa biological bacterium component and an enzyme component, wherein the biological bacterium component comprises lactic acid bacteria, nitrifying bacteria, photosynthetic bacteria, saccharomycetes, bifidobacterium powder and lactobacillus acidophilus; and the enzyme component comprises alkaline protease and tea polyphenol. The compositions can be mutually adjusted to form a symbiotic complementationand common synergism relationship, so that stronger cooperation force is exerted to achieve the effect of removing fishy substances in fish bodies in aquaculture; and according to the preparation method, only the components need to be mixed, the process is simple and easy to control, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a composition for reducing trimethylamine in living fish and a preparation method thereof. Background technique [0002] Aquatic organisms, especially fish, often emit a special fishy smell. Studies have shown that there is a kind of mucus gland in the fish body, and the mucus secreted by the gland contains trimethylamine, and trimethylamine will volatilize into the air at room temperature, forming a strong fishy smell. [0003] And when people take fish meat containing trimethylamine for a long time, it will cause irritation to the throat, esophagus, etc., and make people feel uncomfortable. [0004] On the existing market, there is still a lack of substances capable of reducing trimethylamine in live fish, so the technical solution of the present invention is proposed. Contents of the invention [0005] In order to solve the problems in the prior art, the invention pr...
