The yogurt also contained isoXavones (genistein,
55 g/g F.W.; daidzein, 11 g/g F.W.; glycitein, 21 g/g F.W.)
and several free amino acids (Fig. 2), which have rarely
been detected in other conventional yogurts. Sensory scores on a 5-point scale were higher for high-GABA soya yogurt than conventional yogurt. The scores of GABA soya yogurt in color, flavor and acceptability were over 3.5, whereas the scores of conventional yogurts were around 2.5. The p values of it were less than 0.001 in color, flavor and acceptability and less than 0.05 in taste, respectively, which was helpful to weigh the significance of difference.
