Abstract

The invention discloses a method for degrading fumonisins, which uses gamma rays to radiate a sample containing the fumonisins to obtain the sample with reduced fumonisins content. The method can directly radiate finished products such as agricultural products, food, and feed, has simple operation and obvious effects, and makes the degradation rate of fumonisins B1 reach 63.47 percent.

Description

technical field [0001] The invention relates to a method for degrading fumonisins. Background technique [0002] Fumonisin (F) is a group of water-soluble metabolites produced by Fusarium monliforme Sheld discovered in the late 1980s. It is one of the most harmful mycotoxins to humans and animals. Fumonisin is a structurally similar double lipid compound (FB shown in formula I) composed of different polyhydric alcohols and tricarboxylic acid 1 , FB 2 , FB 3 or FB 4 ), where fumonisin B 1 (FB 1 , C 34 h 59 O 15 N, molecular weight 721) is the major component of fumonisins in contaminating maize or Fusarium moniliforme cultures and is the main cause of the toxic effects of fumonisins (Grelderblom W.C., Jaskiewicz K., Marasas W.F., et al. Fumonisins -novel mycotoxins with cancer promoting activity produced by Fusarium moniliforme. Appl Environ Microbio, 1988, 54(7): 1806-1811). [0003] (Formula I) [0004] Corn is an important global feed resource and starch resou...
