Abstract
Powdery crystalline maltose characterized by a high concentration of the beta-anomer of maltose monohydrate is produced by: (1) obtaining a high purity maltose solution containing not less than 90% maltose and not more than 2.5% maltotriose by enzymatic saccharification of a liquefied starch solution having a low degree of hydrolysis; (2) concentrating the high purity maltose solution to a solid content of 65 to 80%; (3) adding seed crystals of beta-maltose monohydrate; (4) precipitating maltose monohydrate crystals in a primary crystallization stage; (5) spray drying the resulting massecuite to obtain a powdery product with a water content of 5.5-7.5%; and (6) aging the powdery product at a temperature of 50.degree.-75.degree. C., relative humidity of 50-70% and absolute humidity of 45-185 g water/Kg dry air. A product having low hygroscopicity is produced by this method.
