The moisture, crude ash, protein, fat, and carbohydrate contents of ungerminated black soybean flours were 8.72, 5.71, 36.08, 16.82, and 32.67 g/100 g, respectively.
All values are expressed as the mean ± SD of triplicate determinations. Means with different superscripts within a column (a l) are significantly different at p < 0.05 by a Duncan’s multiple range test.
