Wilkens and others (35) reported soy milk produced by hot grinding of soybeans at approximately 80 °C or higher could lower soy odor concentrations in soy milk products.
Endo and others (36) reported heating whole soybeans on hydroperoxide reduction in normal soybean.
They reported that under some steaming and boiling conditions, soybeans could produce soy milk with similar levels of hydroperoxides as that prepared from lipoxygenase-null soybeans.
Sensory evaluation showed that a dessert product prepared from soy milk that was made from heat-treated soybean gave lower beany flavor scores than that made from soybean without preheating treatment.
The low hexanal content in soy milk made from blanched soybeans was consistent with the low-hydroperoxide findings by Endo and others (36).
