Abstract: A method is disclosed for preparing a parting composition for facilitating the release of foodstuffs from cooking utensils, the composition containing an edible oil, lecithin, water, a organic, non-soap fluidizing agent. The water is present in an amount sufficient to partially, but not fully, hydrate the lecithin so as to render the partially hydrated lecithin insoluble in the edible oil. The method includes combining at least the lecithin and fluidizing agent and homogenizing the ingredients to reduce the size of the lecithin platelets. The composition, which may further include a suitable normally gaseous propellant to discharge the composition from a conventional aerosol spray can, provides a substantially clear and smooth spray coating on cooking utensils at ambient temperatures, without the need for ethyl alcohol in the composition. The composition may optionally include conventional modifying agents such as suspending agents, anti-oxidants, preservatives, flavorants, etc.

Abstract: A parting composition for facilitating the release of foodstuffs from cooking utensils contains an edible oil, lecithin, water, a carbonaceous, non-soap fluidizing agent. The water is present in an amount sufficient to partially, but not fully, hydrate the lecithin so as to render the partially hydrated lecithin insoluble in the edible oil. The composition, which may further include a suitable normally gaseous propellant to discharge the composition from a conventional aerosol spray can, provides a substantially clear and smooth spray coating on cooking utensils at ambient temperatures, without the need for ethyl alcohol in the composition. The composition may optionally include conventional modifying agents such as suspending agents, anti-oxidants, preservatives, flavorants, etc. The fluidizing agent, is either a glycerol ester of a fatty acid or a free fatty acid material, fluidizes the lecithin so that if the lecithin settles, it can easily be re-dispersed in the oil.

Abstract: A foodstuffs parting composition for coating cooking surfaces composed of a water-in-oil emulsion prepared from lecithin, an edible oil component, 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, and water. The lecithin is preferably acetylated lecithin, and the preferred emulsifying agent is monocalcium phosphate and is present in an amount of at least about 1 percent by weight of the composition. In alternative embodiments, mono- and diglycerides, including, e.g., phosphated mono- and diglycerides, are used as substitutes for the lecithin. Medium chain triglycerides are sometimes used with or in place of the edible oil as part of the edible oil component.

Abstract: A parting composition for facilitating the release of foodstuffs from cooking utensils contains an edible oil, lecithin and water and, optionally, a humectant such as glycerol. The water is present in an amount sufficient to partially, but not fully, hydrate the lecithin so as to render the parially hydrated lecithin insoluble in the edible oil. The composition, which may further include a suitable normally gaseous propellant to discharge the composition from a conventional aerosol spray can, provides a substantially clear and smooth spray coating on cooking utensils at ambient temperatures, without the need for ethyl alcohol in the composition. The composition may optionally include conventional modifying agents such as suspending agents, antioxidants, preservatives, flavorants, etc.

Abstract: 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.

Abstract: A parting composition for cooking foodstuffs includes a release agent which is a phosphate salt derivative of mono- and di-glycerides of edible fats, oils and/or fat-forming fatty acids, together with an edible oil and a pulverulent blocking agent. The edible oil may be any suitable vegetable or animal oil or shortening, and the blocking agent may be any edible clay, magnesium aluminum silicate, sodium bicarbonate, baking powder, ground limestone, calcium carbonate, calcium or magnesium stearate, flours or edible starches. For example, the blocking agent may comprise cereal flour or cornstarch, or a pharmaceutical kaolin, a food grade benetonite, calcium carbonate, or a mixture of two or more thereof. Preferably, the release agent is a mono-sodium glyceryl oleate phosphate. The composition may also include one or more of water, a suitable suspending agent such as fumed silica, and ethanol; a pressurized hydrocarbon propellant may be added when packaging the composition in a pressurized aerosol container.

Abstract: The invention provides a combustion device such as a stove which may include a pressurized fuel mixture, such as an aerosol container containing alcohol and a propellant which may comprise a normally gaseous hydrocarbon, such as a liquified petroleum gas. The propellant and air are fed to a combustion zone as a combustion mixture, which is combusted therein in a cold start period to pre-heat the liquid fuel and vaporize it. When the liquid fuel is vaporized by the heat provided by combusting the propellant gas, combustion is continued by combusting the vaporized liquid, e.g., alcohol, fuel. The pressurized fuel composition may comprise a major proportion of alcohol together with a minor proportion of the hydrocarbon propellant starter fuel. The method therefore includes carrying out an initial, cold-start phase of combustion utilizing the propellant as fuel, and a subsequent stage of combustion utilizing the vaporized liquid fuel.
