An aerosol-dispensable foodstuffs parting composition for coating cooking surfaces comprising a water-in-oil emulsion containing natural lecithin, refined lecithin or a chemically modified lecithin selected from the group consisting of acylated, preferably acetylated lecithin, hydroxylated lecithin, and acetylated-hydroxylated lecithin, or mixtures thereof; an edible oil; an emulsifying agent; water; and a pressurized, normally gaseous propellant suitable for discharging the composition as an aerosol spray. A procedure for preparing the water-in-oil emulsion comprises mixing together the aforesaid ingredients except the propellant with about 7 to 21% of the total water, to form a concentrate. The remainder of the water and the propellant are added later. The emulsion may also contain one or more of a humectant, a suspending agent, a release agent and a blocking agent.
An aerosol-dispensable foodstuffs parting composition for coating cooking surfaces comprising a water-in-oil emulsion comprising lecithin, an edible oil, an emulsifying agent selected from the group consisting of one or more of monocalcium phosphate, calcium chloride dihydrate, dibasic magnesium phosphate trihydrate and potassium chloride, water, and a pressurized, normally gaseous propellant suitable for discharging the composition as an aerosol spray.
An aerosol-dispensable foodstuffs parting composition for coating cooking surfaces comprising a water-in-oil emulsion comprising from about 4.5 to 20 percent by weight of a fluid chemically modified lecithin, sufficient added edible oil to provide total oil content of from about 20 to 45 percent by weight of edible oil, an emulsifying agent comprising from about 0.1 to 8 percent by weight monocalcium phosphate, water and a pressurized, normally gaseous propellant suitable for discharging the composition as an aerosol spray.
A process for preparing a parting composition comprising a water-in-oil emulsion comprising a total of from about 13% to 67% water by weight of the composition, the process comprising forming a pre-emulsion concentrate by mixing an edible oil with one or more chemically modified lecithins selected from the group consisting of acylated lecithin, hydroxylated lecithin, and acetylated-hydroxylated lecithin, adding an emulsifying agent comprising a monocalcium phosphate with from about 7 to 21% of the total water, homogenizing said ingredients together to form a pre-emulsion concentrate, and then adding the remainder of the total water.
