Compositions comprising fat soluble substances in a glassy carbohydrate matrix
View Patent ↗The invention relates to compositions containing a fat soluble substance in a glassy carbohydrate matrix having maltose or a mixture of low-molecular weight carbohydrates, and, optionally, a high-molecular weight carbohydrate. The compositions can be used for multivitamin tablets, hard gelatin capsules, dry food and feed compositions and for enriching sugar.
1. A composition comprising from about 1 wt % to about 40 wt % of a fat soluble substance and from about 0.1 wt % to about 30 wt % of an emulsifier, encapsulated in a carbohydrate matrix comprising water and a carbohydrate source consisting essentially of maltose, maltose syrup, or a low-molecular weight carbohydrate selected from the group consisting of fructose, lactose, xylose, arabinose, ribose, sugar alcohols, and mixtures thereof.
2. A composition according to claim 1 wherein the fat soluble substance is a fat soluble vitamin selected from the group consisting of vitamins A, E, D and K and derivatives thereof, a carotenoid, a polyunsaturated fatty acid and mixtures thereof.
3. A composition according to claim 2 wherein the fat soluble substance is vitamin A acetate or vitamin A palmitate.
4. A composition according to claim 2 wherein the fat soluble substance is a carotenoid selected from the group consisting of beta-carotene, astaxanthin, apocarutenal, canthaxanthin, apoester, citranaxanthin, and zeaxanthin.
5. A composition according to claim 2 wherein the fat soluble substance is a polyunsaturated fatty acid selected from the group consisting of arachidonic acid (AA), docosahexaenic acid (DHA), and elcosapentaenic acid (EPA).
6. A composition according to claim 1 wherein the low-molecular weight carbohydrate is present in the composition in an amount of from about 30 wt % to about 95 wt %.
7. A composition according to claim 6 wherein the low-molecular weight carbohydrate is present in the composition in an amount of from about 50 wt % to about 85 wt %.
8. A composition according to claim 7 wherein the low-molecular weight carbohydrate is present in the composition in an amount of about 70 wt %.
9. A composition according to claim 1 wherein the emulsifier is selected from the group consisting of polyoxyethylene-sorbitan-fatty acid ester, a chemically modified starch and ascorbyl palmitate.
10. A composition according to claim 1 wherein the carbohydrate matrix further comprises an antioxidant in an amount of from about 0.1 wt % to about 15 wt %.
11. A composition according to claim 10 wherein the antioxidant is selected from the group consisting of sodium ascorbate, ascorbyl palmitate, dl-α-tocopherol, mixed tocopherols, lecithin, and mixtures thereof.
12. A process for preparing a composition comprising preparing an oil-in-water emulsion comprising water and from about 1 wt % to about 40 wt % of a fat soluble substance, from about 30 wt % to about 85 wt % of a carbohydrate source consisting essentially of at least one low-molecular weight carbohydrate, and from about 0.1 wt % to about 30 wt % of an emulsifier.
13. A process according to claim 12 wherein the composition further comprises an antioxidant in an amount of from about 0.1 wt % to about 15 wt %.
14. A process according to claim 12 further comprising drying the emulsion to form a dry powder.
