Abstract
The detoxicaltion method for aflatoxin in fodder features that the fermented bacterial strain is mixed with fodder material, after being crushed or directly, at the conditions of 25-70 deg.c, temperature, 20-80 % humidity and pH 6.0-8.5 for 20-120 min. The said process can degrade aflatoxin in fodder material effectively, mildly and safety, and is suitable for use in fodder producing industry.
Description
The present invention relates to the method that the aflatoxin in a kind of feedstuff carries out detoxification, the bacterial strain of energy aflatoxin degradation is used for the detoxification of the aflatoxin of feedstuff.Aflatoxin is that toxicity is the strongest a kind of in all mycotoxins, extensively is present in the grain type feedstuff, and animal is taken in aflatoxin and causes then that gently body weight decline heavily then can cause death.
In the prior art there be the method for feed aflatoxin detoxification: (1) ammoniation process (being the patented method of the U.S.), this method are used for the toxin of aqueous feed to be removed, and efficiently reaches 98%.(2) orange Flavobacterium method, this method are that this bacterium and feedstuff are cultivated aflatoxin degradation altogether, and this method can make the nutrition of feed descend greatly.(3) the yeast cell wall absorbs the method for aflatoxin.(4) the saccharomyces cerevisiae culture adds the method for combination aflatoxin wherein in the feed to.(5) hydrated aluminum silicate calcium is blended in the feed and forms the absorption of stable compound prevention animal and bird intestines to AFB1 with AFB1.The chemical anti mildew agent method prevents the pollution of mould to feedstuff with spray wine such as group propionic acid compounds or mould enemy, gram are mould in feed, this method is invalid to the toxin that has produced.(7) select mould grain method, this method is that the vulgarian that will go mouldy is chosen from raw material and removed.(8) use ultraviolet irradiation, this method is shone to decompose aflatoxin wherein feed with ultraviolet ray.
Purpose of the present invention is intended to overcome the deficiencies in the prior art and provides a kind of efficient, gentle, safety, the method for aflatoxin in the grain type feedstuff of degrading.
The poison-removing method of the aflatoxin in a kind of feed is characterized in that with Mechanical Crushing behind the strain fermentation or directly mixes with feedstuff that at 25～70 ℃, humidity is 20%～80%, and pH fully mixed 20～120 minutes under 6.0～8.5 conditions.
---described bacterial strain is meant Armillariella tabescens (Armillariella tabescens) or aspergillus niger (Aspergillus niger).
---described feedstuff is meant various grain type feeds.
Below by embodiment the present invention is further described:
1 kilogram of toxic grain trough raw material, add can aflatoxin degradation bacterium analyse fermentate 10g, be 35 ℃ in temperature, humidity is 20%～80%, it 50 minutes was aflatoxin in the degradable feedstuff that system pH7.0 fully mixes.
Claims (3)
1, the poison-removing method of the aflatoxin in a kind of feed is characterized in that with Mechanical Crushing behind the strain fermentation or directly mixes with feedstuff that at 25～70 ℃, humidity is 20%～80%, and pH fully mixed 20～120 minutes under 6.0～8.5 conditions.
2, the poison-removing method of the aflatoxin in the feed according to claim 1 is characterized in that bacterial strain is meant Armillariella tabescens (Armillariella tabescens) or aspergillus niger (Aspergillus niger).
3, the poison-removing method of the aflatoxin in the feed according to claim 1 is characterized in that feedstuff is meant various grain type feeds.
