Advantages

Isoelectric point reduced from 4.46 to 3.91 (SPI-STP) and 4.14 (SPI-STMP)

Emulsifying stability (ESI) and activity (EAI) of phosphorylated SPI significantly improved

Smallest variation in mean particle size observed for STPE-C

STPE-C exhibited best resistance to pH and temperature variations
