Notes:
AflatoxinB1 was extracted from rice contaminated artificially with Aspergillus flavus byusing methanol-water (50:50 v/v). As for experiment group, sodium chloride was added into theextracted solution of AfB1, the excitation wavelength of 365 nm under the fluorescence mode, andthe emission spectrum peak at 440nm were observed. To study the detoxification of AflatoxinB1 inseveral alkaline solutions, the solution of alkaline with difference concentration was added into thesolution of AfB1 respectively. The results showed that all of three alkaline solutions could decreasethe 440nm emission spectrum peak of solution of AfB1 in varying degrees, the effect to decreaseemission spectrum peak of AfB1 was very obvious in sodium hypochlorite (NaClO), and sodiumhydroxide (NaOH) took second place, whereas in ammonia (NH3·H2O), the effect was the weakestamong three alkaline solutions. Moreover, the effects were different in the same alkaline solutionswith different concentration, as hydrochloric acid (HCl) in low concentration was added to thiscomplex AfB1 alkaline solutions, detoxification efficacy of AfB1 were found to be obviouslyincreased. It was concluded that the detoxification of AflatoxinB1 may be affected by alkalinesolutions according to their concentration and be degraded greatly by acid addition
