Furthermore, an oleosin band was observed in the particulate fraction of blanched soymilk (Lane 9) but not in the traditional soymilk counterpart. Soymilk lipids exist in the form of an oil body and are released from the particulate fraction of raw soymilk accompanying the denaturation and dissociation of proteins (Guo et al., 1997). In consequence, only trace amounts of lipids or oleosins are found in the particulate protein of traditional soymilk. By contrast, when the blanching treatment is applied, the 7S is denatured within the soybean seed, thus decreasing protein solubility and entrapping/associating with part of the oil bodies. Accordingly, the considerable lipid content in the particulate fraction of blanched soymilk could be tentatively attributed to the entrapping or associating effect of the protein aggregates formed from the heat-denaturation occurring within the seeds.
