•A sequential extraction of proteins and arabinoxylans from BSG with increasing alkali strength was performed.•A ratio of 1:2 (w/v) at room temperature for 24h saves reagents and energy.•A yield of 82–85% of the BSG total proteins and 66–73% of total AX were obtained.•Alkaline extracts were acidifie...
