Abstract
Novel fractions of inulin are disclosed which have improved water solubility and/or water miscibility at ambient temperatures. The novel fractions are extracted from plant materials containing inulin and have molecular weights below about 2288. The process for preparing the novel fractions includes extracting inulin with water from subdivided plant materials, holding the inulin rich extraction water in a settling tank while maintaining the temperature from about 0° C. to 7° C. which causes higher molecular weight polysaccharides to separate from water soluble lower molecular weight polysaccharides, and separating the water soluble fractions from the higher molecular weight inulin fractions.
