The soybean seed chemical quality traits (including protein content, oil content, fatty acid composition,
isoflavone content, and protein subunits), soymilk chemical character (soluble solid), and soymilk sen-
sory attributes were evaluated among 70 genotypes to determine the correlation between seed chemical
quality traits and soymilk sensory attributes. Six sensory parameters (i.e., soymilk aroma, smoothness in
the mouth, thickness in the mouth, sweetness, colour and appearance, and overall acceptability) and a
seven-point hedonic scale for each parameter were developed. Significant positive correlations were
observed between overall acceptability and the other five evaluation parameters, suggesting that overall
acceptability is an ideal parameter for evaluating soymilk flavour. The soymilk sensory attributes were
significantly positively correlated with the characteristics of the glycinin (11S)/beta-conglycinin (7S) protein ratio, soluble solid, and oil content but negatively correlated with glycitein and protein content. Our
results indicated that soymilk sensory attributes could be improved by selecting the desirable seed chem-
ical quality traits in practical soybean breeding programs.
