Abstract
A process for preparing an aqueous composition for the preparation of optically clear products, especially beverages, having enhanced stability in syrup and bioavailability for human or animal healthcare. The compositions include an oil soluble ingredient and a primary and a secondary surfactant which match the fatty acid profile of the oil soluble ingredient and follow specific ratios of oil soluble ingredient to emulsifier and specific ratios of primary to cosurfactant.
Claims13
A process for preparing an aqueous composition for the preparation of optically clear products having enhanced stability in syrup and bioavailability for human or animal healthcare comprising
- a) mixing 0.001-2.0% of an oil soluble ingredient or 0.1-2.0% w/w of an oil soluble ingredient as a 20-30% dispersion in a suitable oil with 2-10% of an emulsifier mixture having an HLB (hydrophilic lipophilic balance) value of between 10 and 18 and heating to between 25 and 150° C. so as to yield a transparent mixture
- b) combining the mixture with water while continuously stirring to provide a transparent composition
- characterised in that the emulsifier mixture is a combination of a primary surfactant and a secondary or cosurfactant, wherein the fatty acid profile of the emulsifier mixture matches the fatty acid profile of the oil soluble ingredient or the dispersion of the oil soluble ingredient, the HLB of the primary surfactant is greater than the cosurfactant and the weight ratio of oil or oil dispersion to emulsifier mixture is between 1:1 and 1:7 and the ratio of primary to cosurfactant is between 10:1 and 200:1.
