Black currant anthocyanin-containing compositions for foods comprising 1 to 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 of improving visual function, a function of improving blood fluidity, and/or a function of 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 process 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 visual function, a function of improving blood fluidity, or a function of lowering blood pressure, can be provided.

Cette invention concerne des compositions pour aliments contenant de l'anthocyanine issue de conques de type <i>cassis</i>, lesquelles se caractérisent en ce qu'elles contiennent de 1 à 25 % en poids d'anthocyanine de cassis en termes de matières solides. Cette invention concerne également un procédé de production d'une composition pour aliments contenant de l'anthocyanine, lequel consiste à purifier et concentrer du jus de <i>cassis</i>, que l'on utilise comme matériau de départ, é l'aide d'une membrane à osmose inverse chargée. Cette invention concerne également des aliments et des boissons fonctionnels qui contiennent ladite composition pour aliments. Les compositions susmentionnées ainsi que les aliments et les boisson fonctionnels améliorent la fluidité du sang et/ou abaissent la pression sanguine. Les compositions traditionnelles à base d'anthocyanine de <i>cassis</i> ont une faible teneur en anthocyanine, une acidité élevée et une faible stabilité, ce qui les rend inutilisables en qualité d'additifs alimentaires. Le processus de production susmentionné permet toutefois d'obtenir des compositions pour aliments contenant de l'anthocyanine qui possèdent une teneur élevée en anthocyanine, une acidité adéquate et une grande stabilité, et qui peuvent être rajoutées à des aliments ou des boissons. On obtient ainsi des aliments et des boissons fonctionnels qui contiennent ces compositions et qui améliorent la fluidité du sang et/ou abaissent la pression sanguine.
