I made red quinoa tonight. One cup (washed) quinoa, one cup beef broth, one-and-a half cups of water. After cooking, I put a portion in a cup and added a pat of butter. It has a delicate nutty flavor. I'll put it together with other foods tomorrow. I want to get away from any brominated flour or bleached flour. Sadly, most store-bought bread and noodles are made with brominated and/or bleached flour these days. Isn't my quinoa pretty?

Abstract
Unextractable phenolics from plant foods and their role in health benefits have become increasingly important. Meal residues of three quinoa seeds free of fat and extractable phenolics were subjected to acid, alkaline, and enzymatic hydrolyses. The total and individual phenolic compounds released were analyzed, and 19 phenolics, predominantly phenolic acids and several flavonoids, were identified. The concentration of bound phenolics was highest in black quinoa followed by red and white, regardless of the hydrolysis method. Higher phenolic contents also showed stronger antioxidant activities and inhibition of α-glucosidase and pancreatic lipase activities. Carbohydrases, that is, pectinase, xylanase and feruloyl esterase, which effectively liberated bound phenolics are known to be secreted by colonic bacteria, suggesting potential antioxidant and anti-inflammatory effects by these compounds in the large intestine during colonic fermentation. These results can also be applied to treat foods high in bound phenolics to enhance bioaccessibility.
