Application of ultrafiltration in recovery of protein from brewer's spent grain (BSG) was studied In this work. The effectiveness ill removing water and salts was evaluated Results indicated that increasing of cross-now rate could improve the limiting flux More than 92% of the protein was retained by (lie membranes with both MWCO of 5 and 30 kDa The protein contents in the final product were 2009:1: 140% and 15 98 +/- 0 58%, respectively by 2 and 30 kDa membranes compared with that of 4 86 +/- 0 6
