In the case of bitter quinoa, this
result could be attributed to the loss of phenolic in cookingwater. In
fact, the sum of antioxidant activities of post-cooking seeds and
cooking water was similar to that of pre-cooking seeds. As far as
sweet quinoa seeds are concerned, the decrease in their phenolic
content could be due to phenolics breakdown, since the sum of
antioxidant activity of post-cooking seeds and cooking water
consistently differed from antioxidant capacity of pre-cooking seed.
