However, these methods involved the uses of sodium azide and mercury(II) chloride, and may raise safety issues. Acidic solution with small amounts of lactic acid (e.g., 15 g/L) and/or sulfur dioxide (e.g., 0.5 g/L or 0.15%) addition was used to isolate starch from proso (Yanez & Walker, 1986) and black and white fonio (Jideani & Akingbala, 1993)millets. Alkaline solution with low concentration of sodium hydroxide (e.g., 0.1%) or sodium borate buffer (pH = 10, 12.5 mM) containing SDS (0.5%) and Na2S2O5 (0.5%) was employed to extract starch from proso
