As the soymilk was blanched and ground with hot water from 2
to 10 min, the peak area ratio of 3 non-beany aroma compounds
and 5 beany flavor compounds were 0.07, 0.12, 0.09, 0.05, and
0.03, respectively (Figure 2). It increased to 4-, 6-, 5-, 3-, and
2-fold compared with those without hot water treatment between
80 and 100 ◦C. The diversification was from high to low. From
2 to 6 min, the peak area ratio of non-beany flavor compounds
represented a relatively large proportion of the total. These results
suggest that when the appropriate treatment time is selected, nonbeany
compounds will be maintained while beany compounds
will be eliminated or at least reduced.
