10057299 Abstract of the Disclosure Alpha-glycosyl rutin is formed at a high concen- tration by allowing a saccharide-transferring enzyme to act on a high-rutin content liquid in suspension or solution to effect saccharide-transfer reaction. The resultant alpha-glycosyl rutin is easily recovered from the reaction mixture by allowing it to contact with a synthetic macroreticular resin. Alpha- glycosyl rutin is superior in water-solubility, resistance to light and stability to intact rutin, as well as having the physiological activities as intact rutin has. Thus, alpha- glycosyl rutin is favorably usable as a yellow coloring agent, antioxidant, stabilizer, fading-preventing agent, quality- improving agent, preventive, remedy, uv-absorbent and deterio- ration-preventing agent in foods, beverages, tobaccos, cigarets, feeds, pet foods, pharmaceuticals for susceptive diseases, cosmetics including skin-refining agent and skin- whitening agent, and plastics, in addition to the use in vitamin P-enriching agents.
