Abstract
Abstract Edible, liquid, cold-stable glycerides are prepared by (a) hydrogenating soya oil with a nickel catalyst at 110* to 150*C. to an iodine number of 90 to 115, (b) controllably transesterifying the soya oil at 25* to 30*C. with a transesterification catalyst to produce higher melting glycerides, (c) fractionating the material from (b) by slowly cooling it to 0* to 10*C. and keeping it there for 2-20 hours and then separating the solids from the liquid, or (d) mixing the material from (b) in equal proportions with the cold stable oil prepared in (c) and cooling to 10* to 18*C. to crystallize out high melting triglycerides and then keeping the mixture at 25*C. until the solids are converted into the stable crystal form and then cooling or (e) converting the material from (b) optionally after admixing with solids obtained from (c) into margerine.

335 words
A process for the manufacture of at least one of (ii) edible, flowable suspensions of solid glycerides in liquid glycerides, and (iii) mixtures of liquid and solid glycerides, which mixtures are suitable for the manufacture of margarine, which process comprises: 1a. hydrogenating soya oil with a nickel contact catalyst, at 110* to 150* C., to an iodine number of 90 to 115; b. subjecting the hydrogenated soya oil to controlled trans-esterification with a trans-esterification catalyst at 25* to 30* C., to produce higher-melting triglycerides; and c. fractionating the material from step (b) by slowing cooling it to a temperature of 0* to 10* C. and keeping it for at least 2 hours at this temperature, and then separating the solid constituents and recovering the liquid, cold-stable constituents (i); and d. mixing the material from step (b) in about equal proportions by weight with the cold-stable oil obtained from step (c) and then cooling the mixture to a temperature of 10* to 18* C., so that the high-melting triglycerides crystallize out almost completely, and then keeping the mixture at a temperature of about 25* C. until the solid constituents have been converted into the stable crystal form, said crystal form being the Beta ''-modification or Beta -modification and then cooling to produce edible, flowable suspensions, (ii) of solid glycerides in liquid glycerides; or 2a. hydrogenating soya oil with a nickel contact catalyst, at 110* to 150* C., to an iodine number of 90 to 115; b. subjecting the hydrogenated soya oil to controlled trans-esterification with a trans-esterifications catalyst at 25* to 30* C., to produce higher-melting triglycerides; and c. fractionating the material from step (b) by slowing cooling it to a temperature of 0* to 10* C. and keeping it for at least 2 hours at this temperature, and then separating the solid constituents and recovering the liquid, cold-stable constituents (i); and e. combining material from step (b) with solid constituents obtained from step (c) to produce glyceride mixtures (iii) suitable for the manufacture of margarine.
