Detoxification of aflatoxin contaminated corn by methanol extraction. 1982

H M Stahr, and W O Obioha

Corn containing 500 ppb aflatoxin was decontaminated by methanolic extraction. Ninety percent of the aflatoxin was removed in one three-minute blending with a solvent to corn ratio of 4:1. Recycling methanol for additional extractions could be done by removal of aflatoxin by carbon or distillation of the methanol. Methanol costs per bushel of corn without recycling would probably be expensive. By recycling, the cost is estimated to be ten to twenty cents per bushel in a laboratory size experiment. A source of ethanol on the farm could make the process more feasible. Chicks fed decontaminated corn showed no signs of aflatoxin toxicity. Fatty degenerated livers were produced in chicks fed the nondetoxified corn. Other mycotoxins which are not affected by the ammoniation process used to decontaminate corn, can be removed by this process.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick

D000348	Aflatoxins	Furano-furano-benzopyrans that are produced by ASPERGILLUS from STERIGMATOCYSTIN. They are structurally related to COUMARINS and easily oxidized to an epoxide form to become ALKYLATING AGENTS. Members of the group include AFLATOXIN B1; aflatoxin B2, aflatoxin G1, aflatoxin G2; AFLATOXIN M1; and aflatoxin M2.	Aflatoxin

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
