Abstract(s)
Ozone is used in grains to guarantee mycotoxin degradation, microbial inactivation, and insect disinfestation. However, its oxidizing properties can promote changes in the grain constituents, affecting both product properties and process behavior. Even so, the effect of ozone processing on quality properties of grains and their process, was rarely studied. Consequently, this work studied the impact of ozonation processing on the hydration kinetics and selected nutritional
properties of Adzuki beans (Vigna angularis). As the ozone reactiveness increases at high moistures, three different levels of grain moisture were evaluated. The bean nutritional quality was evaluated considering the total phenolic content and antioxidant capacity (both radicals ABTS
and DPPH). The results showed that there was neither significant difference in the hydration kinetics nor in the phenolic compounds and antioxidant capacity after the processing with ozone. Consequently, ozonation is proposed as an alternative in the control of grain contaminants without affecting its quality.
