Abstract

An oil in water (o/w) micro-emulsion comprising:
a. water; b. from about 3% up to about 30% oil; c. from about 0.1% up to about 10% lecithin; d. sucrose monoester as an emulsifier wherein the ratio of the combined amount of a lecithin and sucrose monoester to oil is less than 1; e. propylene glycol wherein the propylene glycol to water ratio by weight is greater than 1; and f. from about 14% up to about 40%, by weight, a sugar selected from the group consisting of fructose, glucose, and sucrose, and combinations thereof; wherein the mean droplet size of the o/w micro-emulsion is about 10 to about 80 nm.

First claim

The invention claimed is:

1. An oil in water (o/w) micro-emulsion comprising:
a. water;
b. from 3% up to 30%, by weight oil, of the total weight of the emulsion;
c. from 0.1% up to 10% of a lecithin;
d. a sucrose monoester as an emulsifier wherein the ratio, by weight, of the combined amount of the lecithin and sucrose monoester to the oil is less than 1;
e. propylene glycol wherein the propylene glycol to water ratio by weight is greater than 1:1; and
f. from 14% up to 40%, by weight, of a sugar selected from the group consisting of fructose, glucose, sucrose, and combinations thereof, by total weight of the emulsion;
wherein the mean droplet size of the o/w micro-emulsion is about 10 to about 80 nm.

2. The emulsion as recited in claim 1 further comprising from 0.1% up to 20% by weight glycerin of the total weight of the emulsion.

3. The emulsion as recited in claim 2 comprising from 10% up to 20%, by weight, glycerin of the total weight of the emulsion.

4. The emulsion as recited in claim 1 , further comprising from 0.08% up to 1%, by weight, of the total weight of the emulsion, a C 2-6 alcohol soluble alcohol.

5. The emulsion as recited in claim 4 further comprising 0.1-0.5% of a soluble C 2-6 alcohol.

6. The emulsion as recited in claim 5 wherein the alcohol is selected from the group consisting of ethanol, a propanol and a butanol.

7. The emulsion as recited in claim 6 wherein the butanol is selected from the group consisting of n-butanol, sec-butanol, isobutanol and tert butanol.

8. The emulsion as recited in claim 1 , wherein the droplet size is 10 to 80 nm.

9. The emulsion as recited in claim 8 wherein droplet size is 10 to 50 nm.

10. The emulsion as recited in claim 1 , wherein the emulsion is provided in the substantial absence of sucrose.

11. A beverage comprising from 0.002% to 0.1% of the emulsion as defined in claim 1 .

12. A process for making an oil/water (o/w) emulsion comprising:
a. mixing a sucrose monoester into propylene glycol at temperature of 40° C. up to 70° C. to form a sucrose monoester solution;
b. mixing water and sugar into the sucrose monoester solution;
c. dissolving a lecithin into the oil to form an oil phase,
wherein the ratio of the combined amount, of sucrose monoester and the lecithin, to oil is less than 1; and
d. mixing the oil phase into the sucrose monoester solution to form a clear micro-emulsion,
wherein the micro-emulsion is formed without a homogenization step.

13. An oil in water (o/w) micro-emulsion comprising:
a. 10.7 to 17% water;
b. 20% by weight oil, of the total weight of the emulsion;
c. 1.5% to 1.8% of a lecithin;
d. 9% to 15% of a sucrose monoester as an emulsifier;
e. 20 to 25% propylene glycol;
f. 17% fructose;
g. 10% to 12.5% glycerin; and
h. 0.5% butanol,
wherein the mean droplet size of the o/w micro-emulsion is from 10 to 80 nm.

14. The emulsion as recited in claim 1 , wherein the sugar selected from the group consisting of fructose, glucose, sucrose, and combinations thereof is from 17% up to 40% by total weight of the emulsion.
