Economical Evaluation of the Direct Enzymatic Manufacturing of Starch Saccharification Products from Dry‐milled Maize. Dry degermed maize can be used as starting material for the production of glucose syrups, glucose sugar, and dextrose monohydrate. The conversion of starch, contained in maize, into soluble carbohydrates takes place by means of amylases, which act specifically and selectively on starch, while protein and cellulose are not effected. Dry degermed maize can be manufactured at a lower cost than an equivalent quantity of refined starch. Therefore it is possible to produce hydrolysis products at a lower cost price, with maize flour as raw material. The investment and operating costs for a “wet milling‐traditional hydrolysis plant” are compared with the corresponding costs for a “dry milling‐enzymatic hydrolysis plant”.
