Abstract
The crystallization of maltopentaose from concentrated aqueous mixture s was studied by differential scanning calorimetry, X-ray diffraction and polarised light microscopy. Under the conditions of study it was o bserved that maltopentaose crystallized as a hydrate, with single crys tals assembling into spherulitic structures. The crystalline hydrate m elted at 78 degrees C with an enthalpy of fusion of 53 J g(-1). (C) 19 97 Elsevier Science Ltd.
