3.1. Distribution of lipid and protein in blanched and traditional soymilks
Soybean protein bodies are ground into fragments and extracted by water during processing. Upon cooking on the raw soymilk, the extracted soy proteins dissociate and reassociate to form particles that differ in size, composition, and morphology (Ono et al., 1991). The traditional and blanched soymilks were fractionated into the floating, soluble (40 nm) fractions by ultracentrifugation (156,000 × g, 30 min); their relative contents are shown in Table 1
