Patent GB-366909-A (GB)
Title: Improvements in or relating to the production of margarine and like edible fat emulsions
IPC: A23D7/005
Filed: 1930-08-01
Abstract: The Specification as open to inspection under Sect. 91 (3) (a) states that substances having hydrophile and lipophile groups in "substantially balanced" relation, and employed primarily as antispattering agents for margerine, also possess emulsifying properties.  Specific substances referred to are: cholesteryl ester of betaine chloride, cetyl dimethyl aminoacetate hydrobromide, cetyl hydrogen sulphate, ceryl potassium sulphate, dicholesteryl phosphate, melissyl calcium phosphate, calcium triricinolein phosphite, sodium stearyl glycollate, sodium monostearine sulphoacetate, cetyl potassium sulphoacetate, cholesteryl sodium sulphoacetate, cetyl sodium sulphonate, ceryl calcium sulphonate, butyl sodium sulphate, octyl sodium sulphate, stearyl glutamic acid, palmityl glycine, monostearyl glucose, monosteary, mannitol, sulphonated cacaobutter, sulphonated beef stearinel digitonin, cholesterol digitonide.  This subject-matter does not appear in the Specification as accepted.ALSO:Sulpho-acetic acid esters are prepared by boiling the corresponding esters of chloracetic acid with sodium sulphite.  Cetyl dimethylamino-acetate hydrobromide is prepared by warming cetyl bromacetate with dimethyl amine in alcoholic solution.  Triricinolein phosphite is prepared by the reaction of phosphorous trichloride on castor oil in ethereal solution.  The Specification as open to inspection under Sect. 91 (3) (a) states that substances having hydrophile and lipophile groups in "substantially balanced" relation, and employed primarily as antispattering agents for margarine, also possess wetting properties.  Specific substances referred to are: cholesteryl ester of betaine chloride; cetyl dimethyl aminoacetate hydrobromide; cetyl hydrogen sulphate; ceryl potassium sulphate; dicholesteryl phosphate; melissyl calcium phosphate; calcium triricinolein phosphite; sodium stearyl glycollate; sodium monostearine sulphoacetate; cetyl potassium sulphoacetate; cholesteryl sodium sulphoacetate; cetyl sodium sulphonate; ceryl calcium sulphonate; butyl sodium sulphate; octyl sodium sulphate; stearyl glutamic acid; palmityl glycine; monostearyl glucose; monostearyl mannitol; sulphonated cacaobutter; sulphonated beef stearine; digitonin; cholesterol digitonide.  The reference to wetting properties does not appear in the Specification as accepted.ALSO:Margarine and other edible fat emulsions (other than butter) are treated by the addition of a small proportion of a substance having hydrophile and lipophile groups and capable of reducing the spattering of the emulsion when fried by at least 10 per cent.  In substances having these properties the hydrophile and lipophile groups are stated to be in "substantially balanced" relationship in the molecule.  The substances employed do not include casein or substances liberating objectionable nitrogenous compounds on storage such as lecithin.  Suitable substances referred to are:-cholesteryl ester of betaine chloride; cetyl dimethyl aminoacetate hydrobromide; cetyl hydrogen sulphate; ceryl potassium sulphate; dicholesteryl phosphate; melissyl calcium phosphate; calcium triricinolein phosphite; sodium stearyl glycollate; sodium monostearine sulphoacetate; cetyl potassium sulphoacetate; cholesteryl sodium sulphoacetate; cetyl sodium sulphonate; ceryl calcium sulphonate; butyl sodium sulphate; octyl sodium sulphate; stearyl glutamic acid; palmityl glycine; monostearyl glucose; monostearyl mannitol; sulphonated cacaobutter; sulphonated beef stearine; digitonin; cholesterol digitonide.  The proportion of substance employed is preferably between 1/40 per cent and 2 per cent of the emulsion, but up to 10 per cent may be used if desired.  The substances are stated also to prevent the separation of water from the emulsions.  Sulpho-acetic acid esters are prepared by boiling the corresponding esters of chloracetic acid with sodium sulphite.  Cetyl dimethyl amino-acetate hydrobromide is prepared by warming cetyl bromacetate with dimethyl amine in alcoholic solution.  Triricinolein phosphite is prepared by the reaction of phosphorus trichloride on castor oil in ethereal solution.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the spattering-reducing substances as also possessing wetting and frothing or foaming properties.  This subject-matter does not appear in the Specification as accepted.
