摘要:
The present invention aims to provide a particulate composition containing pullulan, which can be produced without employing any complicated purification step such as solvent precipitation and, when formed into a film, exhibits a higher rupture strength compared to conventional ones; a process for producing the same; and uses thereof. The present invention solves the above object by providing a particulate composition containing pullulan which is produced from a culture obtained by culturing a mutant of a microorganism of the species Aureobasidium pullulans in a culture medium containing glucose and maltose as carbon sources, without employing a step of removing concomitant saccharides; contains a pullulan fraction and a concomitant saccharide fraction that are respectively insoluble and soluble in 75% by volume of methanol in water; has a percentage of 3% by weight or lower of the content of concomitant saccharides contained in the concomitant saccharide fraction against the content of total saccharides contained in the whole particulate composition, when determined based on the anthrone sulfuric acid method; and contains mannitol; and by providing the process of the same and uses thereof.
