GB660611A - Process for preparing suspensions of solid triglyceride and liquid oil - Google Patents

Abstract

A substantially uniform suspension of finely divided normally solid triglyceride in normally liquid fatty ester is prepared by at least partially converting a solid triglyceride which is capable of existing in the beta crystalline form, suspending the converted triglyceride in the fatty ester and subdividing the triglyceride at any stage in the process to finely divided form so as to form a fluid to pasty suspension having pumpable consistency at a temperature of 70-100 DEG F. The triglyceride is preferably converted to at least 70\sB5 per cent beta form, the quantity being determined by X-ray analysis by methods specified. The particle size is preferably reduced to 60-200 mesh per inch. The triglyceride may be trilaurin, trimyristin, tripalmitin, tristearin or the material obtained by completely hydrogenating an oil such as sunflower seed oil, linseed oil, hazelnut oil, soybean oil, peanut oil, olive oil, corn oil and lard. The liquid constituent may be cotton seed oil, soybean oil, peanut oil, linseed oil, sunflower seed oil, corn oil, olive oil, rapeseed oil, fish oil, the monoglyceride of linolenic acid, diolein, dilinolein, sperm oil, methyl oleate, palmityl oleate, benzyl laurate, ethyl laurate or diethylene glycol monolaurate. In examples, peanut oil, cottonseed oil, or soybean oil each hydrogenated to about 8 iodine value, is rapidly chilled and flaked on cooled rolls, the flaked material is then stored at temperatures between 38 and 62 DEG C depending on the material until a partial or total conversion into the beta crystalline form is effected. The heat treated flakes are then ground in the presence of dry ice or solid carbon dioxide and then suspended in refined and purified peanut oil optionally with the addition of salt and sugar. Specification 660,610 is referred to.ALSO:A substantially uniform suspension of finely divided normally solid triglyceride in normally liquid fatty ester is prepared by at least partially converting a solid triglyceride which is capable of existing in the beta crystalline form, suspending the converted triglyceride in the fatty ester and subdividing the triglyceride at any stage in the process to finely divided form so as to form a fluid to pasty suspension having pumpable consistency at a temperature of 70-100 DEG F.
