Aflatoxin-removed feed prepared from kitchen waste and production technology of aflatoxin-removed feed

Abstract

The invention discloses an aflatoxin-removed feed prepared from kitchen waste and a production technology of the aflatoxin-removed feed. The aflatoxin-removed feed is prepared from the following raw materials in percentage by mass: 40-60% of kitchen waste, 30-45% of wheat bran, 4-8% of citric acid, 3-6% of tea polyphenols, 0.1-0.3% of trace elements, 8-12% of a mildew removing agent, and 10-15% ofmildew removing bacteria, wherein the mildew removing agent comprises the following components in parts by weight: 6-12 parts of glucomannan, 11-15 parts of modified attapulgite, 12-16 parts of sorbic acid, 8-14 parts of sodium propionate, and 13-15 parts of quercetin; and the mildew removing bacteria are prepared by mixing bacillus subtilis with lactobacillus casei and orange flavobacterium in the weight ratio of the bacillus subtilis to the lactobacillus casei to the orange flavobacterium being (1.5-2.5) to (2-3) to (1.8-2.6). According to the aflatoxin-removed feed, the growth and the propagation of mould can be effectively restrained, the metabolic pathway generating AFB1 can be restrained, the removing rate of AFB1 can achieve 91.7%, the removing rate of AFB2 can achieve 83.5%, the removing rate of AFG1 can achieve 61.8%, the removing rate of AFG2 can achieve 86.2%, the content of aflatoxins in the feed can be obviously reduced, and the safety and the feasibility for treating thekitchen waste for the feed can be improved.

Description

technical field [0001] The invention belongs to the technical field of turning kitchen waste into feed, and in particular relates to aflatoxin-free feed prepared from kitchen waste and a production process thereof. Background technique [0002] Aflatoxin, classified as a Class 1 carcinogen by the World Health Organization, is 68 times more toxic than arsenic and 10 times more toxic than potassium cyanide. It is extremely destructive to liver tissue. AFB1 is one of the known aflatoxins The most carcinogenic one. At present, most feeds are produced by microbial fermentation of food waste. Under the action of mold, it is easy to cause a large amount of aflatoxin to accumulate in the feed. AFB1 can reach up to 80μg / kg, which is four times higher than the national standard. Therefore, how to produce Aflatoxin-free feed is an urgent problem to be solved. [0003] The patent application number is CN201410125531.3, which uses cutinase, neutral protease, polyphenol oxidase, hemicel...

Problems solved by technology

At present, most feeds are produced by microbial fermentation of food waste. Under the action of mold, it is easy to cause a large amount of aflatoxin to accumulate in the feed. AFB1 can reach up to 80μg / kg, which is four times higher than the national standard. Therefore, how to produce Aflatoxin-free feed is an urgent problem to be solved

[0003] The patent application number is CN201410125531.3, which uses cutinase, neutral protease, polyphenol oxidase, hemicellulase, glucose oxidase, Polygonum cuspidatum extract, vitamin A and vitamin D to prepare aflatoxin Detoxification enzyme, the detoxification enzyme can not only degrade aflatoxin B1 in the feed, but also hydrolyze macromolecular substances, but the enzyme has strict requirements on the environment, and when the conditions are not suitable, it will be volatile and inactivated, and the cost of the enzyme is relatively high. and reduced practical value

The patent with the application number CN201610602469.1 uses a variety of microorganisms to ferment food waste, but does not degrade aflatoxin and toxic substances. Therefore, the feed produced by this method has a large safety problem
