Abstract

Abstract: Screening design was used in this study for estimating the extracted effects of external factors in protein isolate indouble-low rape-seed meal, with respect to the variables such as pH, ratio of materiel and water(g/ml), temperature, shakingtime, centrifuge time and centrifuge speed. Results showed that the pH, ratio of materiel and water(g/ml) and temperature werethe major affecting factors for extraction of protein isolate in double-low rape-seed meal while the shaking time, centrifuge timeand centrifuge speed were not.

Key words: rape-seed meal, protein isolate, screening design, external factor
