Water-dispersible colouring agents useful as yellow colouring material for fruit juices, ice-cream, yoghourt, caramels, mayonnaise etc. which are not decomposed by ascorbic acid which e.g. occurs naturally in fruit juices, etc. contain one or more crocetine esters of formula (wherein R1 and R2 are alkyl, together having 16-40C atoms) and a physiologically acceptable emulsifier, e.g. palmitoyl ascorbate sodium salt. Esp. good results are obtained with crocetine, di-n-dodecyl ester. |
