Black currant anthocyanin-containing compositions for foods comprising 1 t o 25% by weight of black currant anthocyanin on the basis of solid matters; a process for producing a black currant anthocyanin-containing composition for foods characterized by purifying and concentrating black currant juice employed as a starting material by using a charged reverse osmosis membrane; functional foods and drinks characterized by containing the above compositions for foods; and the above-described compositions for foods and the above-described functional foods and drinks having an effect o f improving visual function, a function of improving blood fluidity, and/or a function o f lowering blood pressure. The conventional black currant anthocyanin compositions have a low black currant anthocyanin content, strong acidity and poor stability, which makes them unsuitable as additives for foods and drinks. However, the production proces s according to the present invention makes it possible to provide black currant anthocyanin-containing compositions for foods which have a high black currant anthocyanin content, an adequate acidity, and a high stability and can be added to foods and drinks. Moreover , functional foods and drinks containing these compositions, which have an effect of improving visualfunction, a function of improving blood fluidity, or a funct ion of lowering blood pressure, can be provided. |
