Abstract
NEW MATERIAL:A yeast glucan having the following physical property values. Elemental analysis; (C:39.1%, H:5.7%, O:54.9%, ash:0.3%). A molecular weight; 50,000W120,000. The decomposition point; carbonized at 270°C. [α]D24; -20W 40°C. Absorption spectrum; no absorption in ultrairolet wave length region, an absorption caused by β-type glycoside bond in infrared region (890cm-1). Solubility; insoluble in water at normal temperature, alcohols, acetone, etc., soluble in hot water (not lower than 75°C), alkaline aqueous solution (pH of not less than 9.5), dimethyl sulfoxide, etc. Colorimetry; positive in anthrone reaction and negative in ninhydrin reaction. Composition; glucose consisting mainly of β-1,3-glucoxy bond. Color; white. A water suspension is neutral. Specific properties; a water suspention gels thermally reversely at not lower than 75°C.
USE: Thicking agents for foods and cosmetic materials, shaping agents for medicines. Carcinostatic agents.
PROCESS: A solid substance obtained by decomposing a yeast fungus by enzyme is dissolved into an alkaline solution having a pH of not less than 12. The pH of the solution is made about 7W9 to precipitate a yeast glucan.
