profiles of the volatile compounds in cooked non-fermented soybeans (CNF) and fermented soybeans (thua nao) are shown in
Table 1. Total volatiles in found autoclaved soybean (CNF2) were three times higher than those in boiled soybean (CNF1). Further-
more, volatiles in CNF2 were comprised of at least 42 components including 9 alcohols, 4 aldehydes, 6 ketones, 3 aromatics, 4 acids
and esters, 3 pyrazines, 4 furans, 2 sulphur-containing, and 7 mis- cellaneouscompounds. Volatiles in CNF1 consisted of only 36 com
