Abstract

A process for making a fructose polymer mixture containing chiefly inulin and inulides with minor amounts of impurities is based on the finding that inulin is in a soluble metastable state at room temperature as it exists in the dahlia tuber. Novel steps in the process are the separation, without the use of heat or adding water, of the water soluble from the ground dahlia tuber within about 10 minutes after grinding, followed by separation by coagulation of protein color and flavor bodies by heating at the boiling temperature from 3 to 10 minutes. No chemical defecating agent, such as lime water is used or required. The resulting clear extract is concentrated to 40% to 70% solids. Dry product is recovered by crystallizing the concentrated extract at 1.degree. to 15.degree. C. The product differs from inulin in that the product, in addition to inulin, also contains inulides, protein, color, flavor bodies, and minerals.
