GB378372A - Improvements in or relating to the production of margarine and like edible fat emulsions - Google Patents

Abstract

For producing improved margarine and like edible fat emulsions there is added thereto a relatively small quantity of one or more compounds having the capacity of preventing spattering of the margarine during frying and a relatively small quantity of one or more "antiweeping" compounds of the type defined in Specification 378,373. The antispattering compound may be lecithin or nitrogenous lecithin-like extracts or antispattering compounds of the kind defined in Specification 366,909. Antispattering compounds of the kind defined in Specification 366,909 but not specifically referred to in that Specification are: mono sodium stearyl sulphate, palmityl hydrogen sulphate, potassium palmityl sulphate, sulphonated beef tallow, mannitol mono-palmitate, stearyl malic acid, the sodium salt of stearyl diethyleneglycol sulphoacetate, "stearic acid ester of sucrose," carbocholesteroxys methyl quinaldylium bromide, cholesteryl dimethyl aminoacetate hydrobromide, compounds having the formulae:- <FORM:0378372/I/1> and sulphonic acid derivatives of substances possessing lipophile groups, e.g. carboxylic esters of sulpho acetic acid, such as salts of monostearyl sulphoacetate. The additional substances may be emulsified directly with the principal oleaginous and aqueous ingredients of the margarine in the liquid stage or they may be formed with a liquid substance into a paste which is kneaded into the margarine after the oleaginous and aqueous substances have been formed into an emulsion and the emulsion has been stabilized to form a solid plastic product. The additional substances may be mixed together prior to the introduction thereof into the emulsion; thus a mixture of the two may be produced by treating one of the antiweeping compounds to increase the hydrophyllic character of the hydrophile group or groups to obtain a mixture of an antiweeping substance with a substance having substantially balanced hydrophile and lipophile groups, e.g. stearic acid may be esterified with glycerol to produce monostearin, an antiweeping substance, and this may then be treated with sulphuric acid to convert a portion thereof to monostearyl sodium sulphate. Reference has been directed by the Comptroller to Specification 339,558, [Class 1 (i), Chemical processes &c.].
