Abstract

The invention discloses a multi-functional micro-ecological nutritional river crab feed with the functions of preventing and removing chemical and heavy metal pollutants in crab cream and crab spawn. The multi-functional micro-ecological nutritional river crab feed is composed of imported fish meal, fermented black seed coat peanut meal, fermented highland barley powder, fermented maize yellow powder, limited enzymolysis castor protein isolate, full-nutritional wall-broken yeast powder, fermented black seed coat peanut coat, micro-ecological preparation microcapsules, fermented microalgae powder, and compound stable vitamins and compound trace elements for crabs. The multi-functional micro-ecological nutritional river crab feed is purely natural and environment-friendly, and has the functions of improving immunity of river crabs, promoting growth of river crabs, enhancing activity of river crabs, enabling river crabs to be full in muscle, increasing the crab cream and crab spawn contents, and preventing and removing chemical and heavy metal pollutants accumulated in the crab cream and crab spawn.

Description

technical field [0001] The invention belongs to the field of aquatic feed processing, and relates to a multifunctional micro-ecological river crab nutritional feed for preventing and removing chemical and heavy metal pollutants in crab paste and crab roe, and is especially suitable for producing crab roe and crab paste without chemical and heavy metal pollutants. Ecological river crab nutritional feed. Background technique [0002] The scientific name of river crab is Chinese mitten crab, which is a rare freshwater product with delicious taste, rich nutrition and high economic value. The edible part of river crab accounts for about 1 / 3 of the body weight, and the nutritional value of river crab is very high. According to analysis, every 100 grams of edible part contains 14 grams of protein, 5.9 grams of fat, 7.4 grams of carbohydrates, vitamin A5960 international units, nuclear The flavin is 0.71 grams, which is higher than that of general aquatic products. There are many b...
