The volatile off-flavour problems associated with soymilk havebeen characterised mainly as green, beany and grassy. Beany The offflavour development in soy milk is primarily due to the lipoxygenase
or the oxidative rancidity of unsaturated fatty acids (Wolf, 1975).
Therefore, soybean oil content and fatty acid composition play important roles in the flavour attributes, despite there limited amounts in soy milk. In our study, a significant positive correlation between oil content and soy milk overall acceptability was observed (r = 0.298⁄) (Table 4), suggesting the oil content benefitsthe soymilk flavour property.
