Abstract
Abstract A procedure for preparing a palatable aerosol foam of unpleasant edible oil containing up to 80% oil is disclosed. This has been achieved by incorporating an inorganic complexing agent, water, a sweetening agent, a sensory masking agent and a propellant present in an amount sufficient by itself to function as the whipping agent and propellant into the oil to form a pleasant tasting suspension without an oily mouthfeel, unpalatable taste and unpleasant odor. Each teaspoon of aerosol foam will contain from about 2 to 4 grams of oil.

Claim 1
Independent Claim
154 words
A palatable aerosol foam composition of unpleasant edible oil comprising: about 20% to about 80% of an unpleasant edible oil; about 4% to about 30% of an inorganic complexing agent insoluble in oil; about 3% to about 30% of water; a sensory agent present in an amount sufficient to sensory mask the unpleasant edible oil resulting in a pleasant edible oil; a sweetening agent; and an edible propellant in an amount of about 5% to about 50%; wherein said inorganic complexing agent is selected from the group consisting of magnesium trisilicate, calcium carbonate, calcium silicate, a codried gel of aluminum hydroxide and magnesium carbonate, magnesium carbonate, ground limestone, ground oyster shells and mixtures thereof forms a viscosity increasing complex with the oil and the sensory masking agent masks the taste and odor of the oil and the propellant is present in an amount sufficient by itself to function as the whipping agent and propellant.
