A process for the production of a protected fat comprises reacting a fatty acid distillate with at least two metal oxides such that the metal oxides react with the free fatty acids present in the distillate to form a mixture of metallic soaps and removing any water from the resultant mixture of metallic soaps. Preferably, a palm fatty acid distillate is used and the metal oxides are magnesium oxide, calcium oxide or zinc oxide. The metal oxides are preferably reacted with at least 66% of the free fatty acids, the reaction is preferably performed at 70 {C and the water can be removed by heating the resultant mixture of metallic soaps to over 100 {C. The process produces an alkaline protected fat that is liquid at normal handling temperatures and can be used in the dairy feed industry to boost milk and/or butterfat yields. |
