  • Publication number: 20090098261
    Abstract: The present invention relates to a preparation method of protein extracts from rice bran which is comprising a process of pre-treating rice bran; producing de-fatted rice bran by removing fat from the pellet; a process of extracting protein from the de-fatted rice bran, generating protein solution; and a process of precipitating protein from the protein solution to obtain final protein extracts from rice bran. The method of the present invention makes it possible to obtain lipid from rice bran, which has been wasted and used only as feed or compost due to fast rancidity and low stability, and to ultimately develop proteineous materials of high quality, non-GMO and no-allergy by extracting protein from the rice bran. In addition, the present invention provides a method of recycling rice bran, which is wasted as a by-product, by adding values to the rice bran.
