Relationship between Secondary Structure and Surface Hydrophobicity of Soybean Protein Isolate Subjected to Heat Treatment
Figure 4
Effects of the heat treatment on the secondary structures of SPI (nonheated SPI sample regards as 0). (a) SPI heated at 70°C with a 2% protein concentration; (b) SPI heated at 70°C with a 5% protein concentration; (c) SPI heated at 80°C with a 2% protein concentration; (d) SPI heated at 80°C with a 5% protein concentration; (e) SPI heated at 90°C with a 2% protein concentration; (f) SPI heated at 90°C with a 5% protein concentration.
