Problems solved by technology

Therefore, substances such as amino acids, nucleotides, and fatty acids in fish body that affect the flavor of fish meat are generally insufficient, resulting in loose fish meat, low crude protein content, high body fat, light flavor, poor palatability, and poor fish meat quality. greatly affected

[0025] Effects of Meat Quality Improvers on the Growth of Grass Carp

[0026] In the feed, no meat quality improver was added as the control group, and different doses of meat improver were added as the test group. There were five groups in total. The specific feed formula was shown in Table 1:

[0027] Table 1 Test Feed Formula

[0028] feed ingredients The proportion(%) fish meal 15.0 soybean meal 20.0 rapeseed meal 20.0 Wheat bran 18.0 corn flour 8.0 Second powder 12 soybean oil 3.0 mineral salt mixture 1.0 vitamin mix 1.0 Choline chloride 1.0 Meat Improver 0.0; 0.3; 0.5; 0.8; 1.0

[0029] The effect of meat quality improver on the growth performance of grass carp: It can be seen from Table 2 that adding 1.0% meat improver increases body length and weight gain significantly compared with the control group. Compared with the control group, there was no significant difference in body length...

[0033] Example 2 Effect of Meat Quality Improver on Meat Quality Index of Grass Carp

[0034] In the feed, no meat quality improver was added as the control group, and different doses of meat improver were added as the test group. There were three groups in total. The specific feed formula was shown in Table 1. The effect of meat quality improver on grass carp muscle nutrient composition: It can be seen from Table 3 that compared with the control group, the difference in muscle nutrient composition in each group added with meat improver was not significant, but the crude protein in each group added with meat improver had a tendency to increase, while Crude fat has a tendency to decrease.

Abstract

The invention discloses a meat quality improver for grass carps and a preparation method for the meat quality improver. The meat quality improver is prepared from the following raw materials in part by weight: 5 to 10 parts of astragalus, 5 to 10 parts of Codonopsis pilosula, 10 to 15 parts of eucommia bark, 5 to 10 parts of lycopene, 1 to 5 parts of plumepoppy extract, 8 to 15 parts of phytase, 1 to 3 parts of cysteamine, 20 to 40 parts of lactosucrose and 20 to 40 parts of montmorillonite. The invention has the advantages that: active ingredients for improving the meat quality of freshwater fishes are scientifically matched; and the meat quality improver can remarkably improve the growth of cultured fishes and reduce the fat content of the fishes, and also improves the elasticity of muscle, chewiness, hardness and cohesion so as to ensure that the meat is fresh and delicious.

Description

technical field [0001] The invention belongs to the field of feed additives for freshwater fish, in particular to a grass carp meat quality improver and a preparation method thereof. Background technique [0002] my country is rich in aquatic resources, with an annual output of 41 million tons of aquatic products, of which freshwater fish accounts for about 1 / 2 of the total. Aquatic products have become one of the important sources of animal protein intake for people. However, for a long time, domestic aquatic product farming has blindly pursued the production of freshwater fish to meet market demand, and has continuously increased the production of artificial breeding. The intensive degree of artificial fish farming is high, the activities of fish foraging and avoiding harm are reduced, and in the process of breeding, the natural growth cycle of fish is forced to be shortened. For example, in the wild environment, grass carp usually grows for three years before serving the...
