Enhanced functionality of pea-rice protein isolate blends through direct steam injection processing

Washington State University students researched the effects of direct steam injection on pea-rice protein.

A summary of their findings:

  • The study demonstrated that using Hydro-Thermal’s Direct Steam Injection (DSI) technology, that the functional properties of Pea and Rice Protein isolates are enhanced while not degrading, but maintaining the amino acid composition and overall protein quality.
  • The high shear and temperature in combination with high pH resulted in creation of modified proteins that become more hydrophilic and improve solubility. Therefore, allowing food processors to have components that disperse better and more easily.
  • DSI also improved emulsifying activity, foam stability, and oil holding capacity. All of which are crucial for food companies requiring natural methods of creating stability in complex food systems that customers constantly demand.
