Title: Permanently pumpable oleaginous suspensions and method for making the same
IPC: A23L25/10
Filed: 1948-12-30
Abstract: A substantially uniform pumpable suspension of normally solid finely divided triglycerides in normally liquid fatty esters is prepared by forming the triglyceride into a finely divided crystalline form whose phase is other than the beta phase, and thereafter converting at least 70\sB5 per cent of the triglyceride by solid phase transformation to the beta crystalline form. Preferably a mixture of 15-60 per cent of normally solid fatty acid triglyceride in a normally liquid fatty ester is agitated at a temperature above 21 DEG C but not more than 2 DEG  C above the minimum beta crystallization temperature of the triglyceride so as to produce the triglyceride in the beta crystalline form without interlacing of the particles.  The triglyceride may be tristearin, tripalmitin, palmito-distearine, the substances obtained by the complete hydrogenation of soybean oil, sunflower seed oil, linseed oil, hazelnut oil, peanut oil, olive 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, and diethylene glycol monolaurate.  In Example 1 a mixture of 50 parts hydrogenated peanut oil with an iodine value of 8 and 50 parts of refined and filtered peanut oil of iodine value 90, was heated to 65 DEG C completely to liquefy the mixture, it was then cooled with mechanical stirring successively to specific temperatures to cause crystallization of the triglyceride in the beta phase.  In further examples hydrogenated soybean oil is used as the triglyceride and olive oil, diolein, corn oil or sperm oil as the liquid fatty ester.  In addition ground peanuts, pecans, almonds, walnuts, cashew nuts, sesame seeds and soya beans may be added to form nut butters, which may be modified by vitamins, sugar and salt. Specification 660,611 is referred to.ALSO:A substantially uniform pumpable suspension of normally solid finely divided triglycerides in normally liquid fatty esters is prepared by forming the triglyceride into a finely divided crystalline form whose phase is other than the beta phase, and thereafter converting at least 70 \sB 5 per cent of the triglyceride by solid phase transformation to the beta crystalline form.
