Correlations between wet-milling characteristics of amaranth grain

Relationships of acid wet-milling conditions (soaking temperature and sulfur dioxide concentration) to laboratory wet-milling characteristics (fraction yields, protein content of fractions, and recovery values) of amaranth seeds were determined. Based on correlation coefficients (Pearson matrix), it...
