ABSTRACT:
Maltopentaose is crystallized from a supersaturated solution of a high-purity maltopentaose, obtained by fractionation of a feed solution, containing maltopentaose along with additional higher and lower maltooligosaccharides, using a strongly-acidic cation exchange resin in a salt form (e.g. alkali- or alkaline-metal form). Crystalline maltopentaose is non-hygroscopic and non-deliquescent. A pulverulent solid containing crystalline maltopentaose is found substantially non-hygroscopic. Crystalline maltopentaose is favorably usable as the substrate to assay serum amylase. Crystalline maltopentaose and pulverulent solid containing the same are favorably usable to produce foodstuffs, pharmaceuticals, cosmetics, and chemicals.
