DON reduction of wheat grain without compromising the lab-scale milling properties of flour

摘要

cqvip:Wheat branwas investigated to be themost commonly contaminated raw material by mycotoxins.However,there are no economical and practical pretreatment methods for industrial on-line application until now.The effect of light debranning on deoxynivalenol(DON)removal,polyphenol oxidase(PPO)activity and flour quality from lab-scale milling were performed.For on-line production,the DON concentration in wheat decreased 15.89%at debranning ratio of 1.2%.For lab experiment,the maximum DON removal for wheat and flour was 23.35%and 21.95%,respectively.However,the PPO activity,browning of dough sheet and flour qualities in lab scale exhibited no significant variation.Light debranning(1.2%)prior to milling could be efficiently applied to on-line wheat production.
