Comparison of rice bran protein through different methods of extraction

Protein content yield were determined and compared with three stages of different extraction treatments in defatted rice bran. These were : Single Stage process (ST), Double Stage process (DT), Multistage Process (MT) and pretreatment (PT). Results showed that the average amounts of protein ranged from 15.17g% to 25.36 g% in different treatments and reached the highest in yeast fermentation treatment. Thus, these indicated that yeast fermentation should be recommended to improve the protein content of extraction of protein from defatted rice bran.
