    • This invention relates to a coloring agent which is soluble and stable in low pH aqueous food systems. The food colorant, Food, Drug and Cosmetic Red No. 3, which contains a carboxylic group, is predominantly in the unionized form below pH 4.5 and is, therefore, at a concentration required for red coloring virtually insoluble. Red No. 3 is rendered soluble by mixing it with water and a hydrophilic surfactant selected from the group consisting of polyoxyethylene (20) sorbitan monostearate, polyoxyethylene (20) sorbitan tristearate and polyoxyethylene (20) sorbitan monooleate and mixtures thereof. The resulting mixture is added directly to an aqueous foodstuff or after first fixing it on or in a carrier.
    • 本发明涉及一种在低pH水溶性食品体系中可溶和稳定的着色剂。 含有羧基的食品着色剂“食品,药物和化妆品红3号”主要以低于pH 4.5的工会化形式,因此红色着色所需的浓度几乎不溶解。 通过将水与水和选自聚氧乙烯(20)脱水山梨糖醇单硬脂酸酯,聚氧乙烯(20)脱水山梨糖醇三硬脂酸酯和聚氧乙烯(20)脱水山梨糖醇单油酸酯及其混合物的亲水性表面活性剂混合,使红色3变得可溶。 将所得混合物直接加入到含水食品中,或者首先将其固定在载体上或载体中。
