| Research Abstract |
In this research project, the formation of lipid-origin compounds during processing and cooking of soybean foods and their effects on flavor were investigated. Gas chromatograph-mass spectrometry (GC-MS) and gas chromatograph-olfactometry (GC-O) were used for analysis. Head space gas were concentrated by solid-phase microextraction (SPME) method.
In the preparation of soybean milk, hexanal predominantly contributed to the beany flavor, however, other lipid-origin compounds also contributed to the flavor. In the heating of soybean oil and soy protein isolate, many compounds other than hexanal contributed their flavor. Though most of the compounds were thought to be derived from lipids, some of them may be from other food components.
