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.
含黑醋栗花青素的食品用组合物,以固体物质为基准,包含重量百分比为 1%至 25%的黑醋栗花青素;生产含黑醋栗花青素的食品用组合物的工艺,其特征在于使用带电反渗透膜纯化和浓缩作为起始原料的黑醋栗汁;功能性食品和饮料,其特征在于含有上述食品用组合物;以及上述食品用组合物和上述功能性食品和饮料具有改善视觉功能、改善血液流动性和/或降低血压的作用。传统的黑醋栗花青素组合物的黑醋栗花青素含量低、酸性强且稳定性差,因此不适合用作食品和饮料的添加剂。然而,根据本发明的生产工艺,可以提供含黑醋栗花青素的食品用组合物,这些组合物具有较高的黑醋栗花青素含量、足够的酸度和较高的稳定性,可以添加到食品和饮料中。此外,还可以提供含有这些组合物的功能性食品和饮料,它们具有改善视觉功能、改善血液流动性或降低血压的功能。
