A stable product containing an aqueous solution of one or more carotenoids for use in supplementing aqueous systems, such as foods, beverages, dietary supplements, and personal care products, with the carotenoid. An ester is dissolved in water and a source of the carotenoid is added to the solution. The concentrated product may be added to the aqueous systems or dried to form a powder that is readily dispersible in aqueous systems. The product may also include an antioxidant to preserve the activity of the carotenoid. Esters particularly suited for use include sucrose fatty acid esters. The product is produced without the use of organic solvents or elevated temperatures. The particles of carotenoids dispersed in the liquid form of the product will pass through a 0.2 micron (μm) sterile filter.
一种稳定的产品,包含一种或多种类胡萝卜素的水溶液,用于补充水性系统,如食品、饮料、膳食补充剂和个人护理产品,与类胡萝卜素。酯溶解在水中,然后将类胡萝卜素的来源添加到溶液中。浓缩的产品可以添加到水性系统中,或干燥成易于分散在水性系统中的粉末。产品还可以包括抗氧化剂,以保持类胡萝卜素的活性。特别适用的酯包括蔗糖脂肪酸酯。该产品在不使用有机溶剂或高温的情况下生产。分散在产品液态中的类胡萝卜素粒子将通过0.2微米(μm)的无菌过滤器。
