Abstract
Laevulose is obtained by hydrolyzing inulin obtained by extracting with water inulin-containing vegetable matter, e.g. chicory, dahlia bulbs, or sweet potatoes, which has been previously heated to at least 80 DEG C., passing through the range 50-70 DEG C. as rapidly as possible to destroy the inulase present, precipitating and removing the impurities by the addition of an alkaline substance such as milk of lime to produce a pH not greater than 11, and then crystallizing the inulin. The vegetable matter, after drying and before extraction, is preferably softened in water at a temperature below that of solution of the inulin. During extraction, which is preferably effected by counter - current diffusion with water at 75-85 DEG C. vegetable acids may be precipitated, and then, while maintaining the temperature, the milk of lime is added. The liquid, before or after filtration, is saturated with carbonic acid or other acid to precipitate the lime, and the inulin is crystallized out and hydrolysed in the normal way.ALSO:Laevulose is obtained by hydrolyzing inulin obtained by extracting with water inulin-containing vegetable matter, e.g. chicory, dahlia bulbs, or sweet potatoes, which has been previously heated to at least 80 DEG C., passing through the range 50-70 DEG C. as rapidly as possible to destroy the inulase present, precipitating and removing the impurities by the addition of an alkaline substance such as milk of lime to produce a pH not greater than 11, and then crystallizing the inulin.
