Abstract
The present invention relates to a composition for coloring foods, beverages, animal feeds, cosmetics or drugs comprising 1) dissolved carotenoid emulsified as an oil-in-water emulsion using a first hydrocolloid and 2) crystalline carotenoid encapsulated in a second hydrocolloid, making it water-dispersible and thereby miscible with the oil-in-water emulsified carotenoid fraction, mixed in a ratio of between 1:10 to 10:1 and wherein the first hydrocolloid is native casein.
Claims11
A liquid coloring composition comprising:
- a) an oil-in-water emulsion comprising a carotenoid dissolved in an oil phase, wherein the oil phase is emulsified in an aqueous phase using a first hydrocolloid and wherein the oil phase is present in an amount of between 5% w/w to 25% w/w of the oil-in-water emulsion and wherein the first hydrocolloid is present in amount from about 1% w/w to about 20% w/w of the oil-in-water emulsion;
- and
- b) a formulation of water dispersible carotenoid particles encapsulated with a second hydrocolloid, wherein the second hydrocolloid is present in an amount of at least 2% w/w of the formulation;
- wherein the ratio of a):b) is between 1:10 to 10:1;
- wherein the total carotenoid content of a) and b) is between 0.1% w/w to 15% w/w, preferably between 1% w/w to 5% w/w of the resulting liquid coloring composition;
- and
- wherein the first hydrocolloid is native casein.
4 more elements
A method for preparing a liquid coloring composition comprising the steps of:
- a) preparing an oil-in-water emulsion of a dissolved carotenoid using a first hydrocolloid by:
- i) preparing an aqueous phase;
- ii) preparing an oil phase by heating a fat comprising the carotenoid to a temperature suitable for dissolving the carotenoid;
- and
- iii) mixing the oil phase in the aqueous phase;
- b) preparing a formulation of carotenoid particles encapsulated in a second hydrocolloid by milling process;
- and
- c) mixing the oil-in-water emulsion of a) with the encapsulated carotenoid particle formulation of b) in a ratio of between 1:10 to 10:1;
- wherein the first hydrocolloid is native casein.
