臭氧熏蒸对玉米赤霉烯酮降解效果研究

RESEARCH ON DEGRADATION EFFECT OF ZEARALENONE BY OZONE FUMIGATION

研究了利用臭氧气体降解玉米籽粒中玉米赤霉烯酮毒素(ZEN)效果。通过室内试验研究不同处理方式、温度以及玉米水分条件下,臭氧降解玉米籽粒中玉米赤霉烯酮毒素(ZEN)的效果情况。结果表明,臭氧能够降解玉米中的玉米赤霉烯酮毒素(ZEN),臭氧对水分高的玉米籽粒的毒素降解率效果较低水分的好,且在低温条件下臭氧降解效率将会下降。本研究为后续实仓开展臭氧降解真菌毒素实验和臭氧消解储粮中真菌毒素提供了数据支撑。

Our research aims at the degradation of zearalenone(ZEN)in corn kernel by ozone gas.Through laboratory test,our research analyses the degradation effect of zearalenone by ozone on condition of different treatment methods,temperature and corn moisture.As the results show,that ozone gas can degrade zearalenone in corn kernel,and the ozone degradation efficiency is higher in high moisture of corn kernel than that in low moisture of corn kernel.Our result also proves that the efficiency of ozone degradation will decrease at low temperature by contrast of that at normal temperature.Our analysis provides test data that will support warehouse experiment on ozone degradation of mycotoxin and mycotoxin degradation in stored grain.
