Effect of atmospheric pressure cold plasma (ACP) treatment on the hydration properties of quinoa flour

This study is aimed to determine the effect of atmospheric pressure cold plasma treatment on hydration properties of quinoa flour and gel. Regarding, whole quinoa grains were subjected to a dielectric barrier discharge contained plasma reactor for ۵min/ ۵۰ kV, ۱۰ min/ ۵۰ kV, ۵ min/ ۶۰ kV and ۱۰ min/ ۶۰ kV known S۱, S۲, S۳ and S۴ respectively. Increase observed in water holding capacity value of S۱ compared to control with ۳.۷۰-۰.۰۳ g/g and ۳.۴۲-۰.۰۴ g/g respectively verify the increased hydrolytic depolymerization of starch induced by ACP treatment. As treatment parameter determine the technological characteristics and consequently the applicability of quinoa flour, an optimization is required.
