Title:
高度不飽和脂肪酸のカルシウム塩の製造方法
Document Type and Number:
Japanese Patent JP3950047
Kind Code:
B2
Abstract:
A method for the preparation of free-flowing calcium salts of highly unsaturated fatty acids, which includes the steps of:(a) providing a fatty acid feedstock consisting essentially of:(i) from about 50 to about 95% by weight of unsaturated C:16-C:22 fatty acids;(ii) from about 5 to about 40% by weight of saturated C:14-C:22 fatty acids; and(iii) no more than about 6% by weight of moisture, insolubles and unsaponifiables,with no more than about 20% by weight of the unsaturated feedstock being in the form of glycerides;(b) adding to the unsaturated feedstock from about 1.0 to about 2.5 equivalents of calcium oxide relative to the unsaturated feedstock, so that a reactive admixture is formed; and(c) adding to the reactive admixture from about 2 to about 5 equivalents of water relative to the calcium oxide, so that the calcium oxide hydrates and neutralizes the fatty acids to form the calcium salts;provided that when less than 1.75 equivalents of calcium oxide is added, the unsaturated feedstock comprises at least 25% by weight of the saturated fatty acids and is heated to a temperature above its melting point before the step of adding the calcium oxide.
