Wet Milling of Cereal Grains - NALDC

known as the Alsatian process, consists of steeping, grinding, and out the starch, without pre-vious fermentation. The methods have replaced by the Martin process the batter process, both of which are wet-separation, not wet-milling, methods. Wheat starch was also made during the Second World War by a modification of the corn wet-milling
