PREPARATION OF RAPESEED PROTEIN CONCENTRATE BY WASHING WITH ACETONE SOLVENT

摘要

From defatted and dehullted rapeseed meal, using mixed solvent optimized by Response Surface Methodology which consists of 78%―85% acetone water solution at pH4 and 7% sodium chloride to prepare rapeseed protein concentrate, the product could reach 70% in protein content and was light in color, bland in taste. Its nitrogen solubility, water absorption, oil absorption, whippability and foam stability were evaluated also. Compared to soybean protein isolate, it was same good in some aspects. These characters were fitting to be used as food additives.
