PROBLEM TO BE SOLVED: To provide sweetpotato fermented food comprising complex functional food, produced by fermenting sweetpotato with distilled rice spirit (Awamori) malt, monascus and Aspergillus oryzae, and having various kinds of preventive effects on circulatory system disease so as to correspond to a complex risk mechanism of lifestyle-related disease, and to provide a method for producing the functional food.SOLUTION: The malt food is obtained by mixing Monascus, Aspergillus oryzae and Awamori together, adding heated sweetpotato to the mixture, to make the mixture into paste and make the mixture paste cause enzymatic reaction. The method for producing the malt food is provided. The food can be taken as a health drink, since it is or diluted, is usable as dressing for salad or as a seasoning, also may be mixed with sugar, juice, various kinds of seasoning or the like, and is widely usable as a cooking material, confectionery raw material, drink raw material, health food raw material, or the like. The malt food contains &gamma-aminobutyric acid and/or lovastatin derived from Monascus. Starch in the Monascus or rice malt is subjected to enzymatic hydrolysis to present sweetness, and anthocyanin comprising Monascus pigment, and has high antioxidant power is extracted, to make the food express bright red-purple color.COPYRIGHT: (C)2009,JPO&INPIT【課題】泡盛麹、紅麹および黄麹と紅芋を発酵させてつくる機能性食品とその製造方法に関し、生活習慣病の複合的なリスクメカニズムに対応すべく、循環器系疾患の各種予防効果を奏する複合的機能性食品を実現する。【解決手段】紅麹と黄麹と泡盛を混ぜ、さらに加熱処理した紅芋を加えてペースト化した状態で、酵素反応させてなる麹食品とその製法であり、健康酒としてそのまま、または水などでうすめて摂取できる。サラダのドレッシングや調味料としても使用できる。糖類や果汁、各種調味料等と混合してもよく、調理用素材や製菓原料、飲料原料、健康食品原料など、用途も多い。この麹食品は、紅麹由来のγ-アミノ酪酸やロバスタチンを含有している。また、紅芋や米麹中の澱粉が酵素分解されて甘味を呈し、しかも紅芋の色素であり抗酸化力の高いアントシアニンが抽出され、あざやかな赤紫色を呈する。【選択図】なし。
