对氧化作用稳定的β-胡萝卜素和其它类胡萝卜素的水包油分散体，该分散体即使在多磷酸盐存在下，特别是六偏磷酸钠存在下仍是稳定的。这些水包油分散体的典型制备方法是将含有至少约5％的胶体类胡萝卜素的水分散性珠粒同水相接触以形成类胡萝卜素小滴，这些小滴同足够的油相密切接触，从而使类胡萝卜素对氧化作用是稳定的，甚至在没有例如抗坏血酸那样的有效抗氧化剂存在下仍是稳定的。本发明的水包油类胡萝卜素分散体特别有用于稀果汁饮料以提供维生素A强化和色彩，以及其它要求维生素A强化和/或色彩的油/水食品和饮料中。 Oil-in-water dispersions of beta -carotene and other carotenoids that are stable against oxidation, even in the presence of polyphosphates, especially sodium hexametaphosphate. These oil-in-water dispersions are typically prepared by contacting a water-dispersible beadlet comprising at least about 5% colloidal carotenoid with the water phase to form droplets of the carotenoid that are in intimate contact with sufficient oil phase such that the carotenoid is stable against oxidation, even in the absence of an effective antioxidant such as ascorbic acid. The oil-in-water carotenoid dispersions of the present invention are especially useful in dilute juice beverages for providing vitamin A fortification and color, as well as other oil/water food and beverage products where vitamin A fortification and/or color are desired.
