1,252,264. Food spread. UNILEVER Ltd. 3 Dec., 1968 [4 Dec., 1967], No. 57439/68. Heading C5C. A food spread comprises an unworked cooled emulsion containing 70-90% edible fat, having a dilatation value at 25?? C. of 100-400, which is dispersed in the emulsion together with part of the aqueous component in a continuous phase constituted by the remainder of the aqueous component, the emulsion being maintained in a destabilized condition of 0??15-0??75 (defined) by an emulsifier system. The emulsifier system comprises an emulsifier for stabilizing the fatty emulsion and an emulsifier for maintaining the spread in the destabilized condition. These functions may be fulfilled by a single emulsifier such as polyoxyethylene monostearate, stearyl alcohol ethylene oxide ether and polyoxyethylene sorbitan monostearate or by a mixture of stabilizing and destabilizing emulsifiers selected from proteinaceous colloids, glycerol or sorbitol partial esters of C 16 -C 24 fatty acids of HLB factor 3??5-7 and non-ionic emulsifiers of HLB factor 12-18. The fat phase preferably comprises vegetable oils rich in polyunsaturated fatty acids optionally mixed with butter oil, and/or interesterified hard fats. Optional ingredients are NaCl, and sorbic acid. The proteinaceous colloid may be a phospholipid, egg-yolk or sodium caseinate.
