A novel and efficient procedure named “reducing end modification method” was developed for manufacturing high purity maltooligosaccharides. By the method, high purity maltose and maltotetraose were prepared from starch. Starch was liquefied, debranched, and oxidized with sodium hypochlorite at the reducing end. The reaction mixture was treated with β-amylase or maltotetraose-forming amylase from Pseudomonas stutzeri IFO-3773, resulting in the production of high purity maltose or maltotetraose, oxidized maltooligosaccharides, and oxidized undigested dextrin. High purity maltose (maltose content, 99.9%) or maltotetraose (maltotetraose content, 95%) was obtained very effectively from the reaction mixture by chromatography on a strong acid cation exchange resin (Na ⁺).
