especially those presenting in both boiled and autoclaved soybeans, exceeded
their threshold values. It is suggested that the volatiles might be liberated from autoxidation and enzymatic oxidation of unsatu-
rated fatty acids plus Strecker degradation and Maillard reactions (Hodge et al., 1972; Kato et al., 1981). Enzymatic oxidation of these
products might arise from the interaction of lipoxygenase and its substrates, linoleic and linolenic acid (Guss, Richardson, & Stah-
mann, 1967)
