A process for producing a soy protein-containing composition and a soy protein-containing composition

摘要

PROCESS FOR PRODUCING A COMPOSITION CONTAINING SOY PROTEIN AND COMPOSITION CONTAINING SOY PROTEIN. The present invention relates to a novel process for treating soy proteins with multi-anionic reagents. Processes include treating an acid precipitated soy protein rennet with a multi-anionic species to modify the electrostatic charge on protein molecules to improve the functionality of the resulting soy protein containing composition when used in acidic environments. The resulting soy protein-containing composition has improved solubility, suspendability, and stability in acidic environments, and is highly suitable for use in acidic beverages. The processes may optionally include the steps for using a stabilizing agent and for a phytase treatment to further enhance the soy protein containing composition.
