Effect of Ozone Treatment on the Degradation of Ochratoxin A and Fatty Acids in Corn

doi:10.7506/spkx1002-6630-201121003

Abstract

Abstract: The feasibility of applying ozone in corn storage was analyzed in the present study with the purpose of solving food safety issues caused by mycotoxin contamination during the storage of cereal grains. In the present study, the effects of ozone treatments at the concentrations of 10, 30 g/m3 and 60 g/m3 and exposure time (1－10 h) on the degradation of ochratoxin A (OTA) in corn and its fatty acid composition were explored. The results indicated that OTA at 80μg/L was completely degraded after ozone treatment at 30 g/m3 for 120 min or at 60 g/m3 for 90 min. Corn contaminated with 80μg/kg OTA was degraded to less than 5μg/kg after being treated by 60 g/m3 ozone for 10 h. Ozone had little effect on the fatty acid compostion in corn. Therefore, ozone can be used for the storage of corn as a result of effective degradation of OTA by it.

Key words: ozone, corn, ochratoxin A(OTA), fatty acids
