PROBLEM TO BE SOLVED: To provide a composition having efficient water solubility, excellent effects on prevention of dye decoloration, prevention of deterioration of flavor or the lie, especially excellent in deterioration preventing effect of oil and fat-containing foods.SOLUTION: There is provided a rutin derivative composition containing enzyme treated rutin and an Ampelopsis cantoniensis extract. The enzyme treated rutin is an α-glycosyl rutin containing product obtained by transferring saccharide (glucose) from a saccharide donor to rutin with adding the saccharide donor to rutin and reacting a glucose transferring enzyme and preferably has the dihydro myricetin of 20 to 98 wt.% in the Ampelopsis cantoniensis extract.COPYRIGHT: (C)2015,JPO&INPIT【課題】十分な水溶性を有し、色素の退色防止、香料等の劣化防止等に優れた効果を有し、特に油脂含有食品の劣化防止効果に優れた組成物の提供。【解決手段】酵素処理ルチンと藤茶抽出物とを含むルチン誘導体組成物。前記酵素処理ルチンが、ルチンに糖供与体を加え、グルコース転移酵素を作用させて糖供与体からルチンに糖(グルコース)を転移させることにより得られる、α-グルコシルルチン含有物であり、前記藤茶抽出物中にジヒドロミリセチン量が20~98重量%含まれていることが望ましいルチン誘導体組成物。【選択図】なし
