Loach coated feed capable of realizing soybean meal fermentation modification by sophora japonica polysaccharides and improving delicious degree of fish and preparation method for loach coated feed

Abstract

The invention discloses a loach coated feed capable of realizing soybean meal fermentation modification by sophora japonica polysaccharides and improving delicious degree of fish and a preparation method for the loach coated feed. The loach feed prepared by the preparation method is scientific and reasonable in formula, can meet the growth needs of loaches at each stage; the feed palatability is improved, the soybean meal is taken as a main raw material, and the modification of soybean meal fermentation is realized by virtue of induction of the sophora japonica polysaccharides, so that the growth of loaches is greatly promoted, the immunity of the loaches is improved, the nutrient content and the grade level of the fish are improved; the added nutritional components can provide proteins, amino acids, trace elements and the like necessary for growth of the loaches; the feed does not contain chemical substances such as antibiotics and hormone, can effectively improve the culture benefits and can reduce environmental pollution. Compared with a conventional feed, the loach coated feed contains more free amino acids and vitamins, can effectively improve the meat quality of fish, so that the fish is more tender, compact and elastic, and is delicious in taste.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a loach coated feed which realizes fermentation and modification of soybean meal and improves the freshness of fish meat through Sophora japonica polysaccharide and a preparation method thereof. Background technique [0002] Loach belongs to the genus Loach of Cypriniformes, and likes to live in the bottom of still water such as lakes, ponds, paddy fields and ditches. Loach is an omnivorous small fish with a wide range of feed sources. Loach has delicate meat, delicious taste, rich nutrition, high content of essential amino acids, and comprehensive composition. It is an important variety for export earnings. However, with the continuous deterioration of water quality and excessive capture, the yield of wild loach has declined, and artificial breeding of loach has become the general trend. The viability of loach is extremely strong, and some areas have tried to develop from...

Problems solved by technology

However, this program also has obvious disadvantages: the one is that the feed ingredients are relatively lacking, especially the green feed and vitamin content are scarce, resulting in incomplete nutrition of the feed, resulting in a decline in loach meat texture and deliciousness; the other is that during feed processing, The technology adopted is relatively single, mainly based on enzymatic hydrolysis, while neglecting the preprocessing and flavoring treatment of soybean meal, resulting in greatly reduced mouthfeel and taste of feed products, which is not conducive to the improvement of loach appetite; the third is in the feed The granules lack the necessary coating treatment. After the feed is fed into the water, due to the lack of stability in the water, it is often stirred up and down by the loach, resulting in a large waste of feed, and at the same time, it also deteriorates the water quality and easily causes the loach to get sick.
