YEAST PROTEIN ISOLATE WITH REDUCED NUCLEIC ACID CONTENT AND PROCESS OF MAKING SAME

摘要

This disclosure relates to a yeast protein isolate (IYP) with less than 9% nucleic acid (RNA) and a Protein Equivalence Ratio (PER) of greater than 1. The yeast protein is made by a process which involves rupturing yeast cells, removing the cell wall residue from an alkaline medium, incubating in such a manner that the endogenous nuclease contained in the solubles portion degrades the nucleic acid present to a soluble form, insolubilizing the protein to separate it from the hydrolyzed nucleic acid, and separating the insoluble protein from the fraction containing soluble nucleic acid.
