Ozone to Overcome Aspergillus flavus and Aflatoxin in Grains: Opportunities and Challenges of Implementation

Ozone can be used as an alternative to control mold and aflatoxins in grains that is more eco-friendly because it does not leave residues that are harmful for humans, animals and environment. The use of ozone was quite effective in reducing mold and aflatoxin in grains such as barley, whole wheat, corn and rice. In Indonesia, ozone was limited used for sterilization of fruit and vegetable. Therefore, the comprehensive review on the potential of ozone in grains is needed, especially on the priority commodities of agricultural development in Indonesia, such as rice and corn. The objective of this review was to examine the opportunities of ozone to reduce Aspergillus flavus and aflatoxin in grains, so that it can improve its quality and shelf life. Many studies showed that the use of ozone reduced Aspergillus flavus and aflatoxin in grains by 50-90%
