Therefore, the two-phase UHT heating method with
the equipped vacuum chamber was very effective to reduce soy
odor. As compared to the literature, Sun et al. found hot
temperature grinding, followed by a 95 °C and 10 min of
heating, gave a similar hexanal content (242 ppb) as compared
to that (264 ppb) ground at 25 °C. Lv et al.16 were able to
reduce the hexanal level to 20−70 ppb after hot grinding at 80−100 °C and followed by heating at 93−95 °C for 5 min.
