Directed-interesterified glyceridic oils having a high linoleic acid content and process for their production
Abstract
Abstract GLYCERIDIC OILS HAVING A HIGH LINOLEIC ACID CONTENT, AND HAVING INSUFFICIENT SOLID TRIGLYCERIDES TO FORM A PLASTIC MARGRINE, ARE SUBJECTED TO A DIRECTED INTERSTERIFICATION PROCESS AT TEMPERATURES OF 0* TO -15*C. USING AS A CATALYST AN ALKALI METAL ALKOXIDE ALONG WITH AN APROTIC SUBSTANCE, NAMELY DIMETHYL SULFOXIDE, DIMETHYL FORMAMIDE, DIMETHYL ACETAMIDE, DIMETHYL CYANAMIDE, OR 3,3-DIMETHYLAMINOPROPIONITRILE. THE COMBINATION CATALYST ALLOWS THE INTERESTERIFICATION TO PROCEED AT A HIGHER RATE THAN WHEN AN ALKOXIDE ALONE IS USED, FORMING SUFFICIENT SOLID TRIGLYCERIDES, IN SEVEN DAYS OR LESS, THAT A PLASTIC MARGARING HAVING A LINOLEIC ACID-TO-SATURATED ACID RATIO OF 8-TO-1 CAN BE MADE THEREFROM WITHOUT THE PRESENCE OF ANY HYDROGENATED STOCK, OR HAVING A LINOLEIC ACIDTO-SATURATED ACID RATIO OF 6-TO-1 WITH A SMALL PROPORTION OF HARDSTOCK.
