Lozano and others (2007) likewise analyzed the FD value of
soymilk flavor. In their research, the soybean was predried at
93.3 ◦C for 10 min to separate the hull, and then the hulled
soybeans were soaked with odorless distilled water. A double “hotgrinding”
step was to create an emulsion and limit LOX activity
by keeping the temperature at about 80 ◦C. They also obtained
12 types flavor compounds using a DHDA-GCO method, the
FD values of these compounds were greater than or equal to 25.
However, although the procedures of obtaining soymilk varied, the
contributions of flavor compounds (n-hexanal, trans-2-octenal, 1-
octen-3-ol, and trans,trans-2,4-decadienal) to soymilk flavors all
existed in the 2 soymilk products. These results suggest that the
beany and non-beany compounds were all in soymilk processed
with different technologies. Furthermore, this shows that different flavor compounds can exist in the soymilk with various processing
methods.
