1. Pourable water and oil containing emulsion comprising a continuous fatty phase and a dispersed aqueous phase, and gas bubbles, characterised in that said gas bubbles are substantially dispersed in the aqueous phase. 2. Pourable water and oil containing emulsion according to claim 1, comprising 20 to 98 wt% of a fatty phase, and 80 to 2 wt% of an aqueous phase comprising 5 to 20 vol% gas such that the average density of the aqueous phase differs at most 5% from the density of the oil phase. 3. Pourable water and oil containing emulsion according to any of claims 1-2, wherein the gas is nitrogen or air or a combination thereof. 4. Pourable water and oil containing emulsion according to any of claims 1-3 characterised in that said product has a stability against sedimentation as defined in this specification of at least 4 weeks. 5. Method for the preparation of a pourable water and oil containing emulsion according to any of claims 1-4, characterised in that the method includes the following steps: a) providing an aqueous-foam solution; b) mixing said aqueous-foam solution with said fatty phase; c) dispersing said aqueous-foam solution in the fatty phase when stirring, wherein the water droplets with adequate, approximately oil matching density, are separated from other water droplets. 6. Method according to claim 5, wherein the separation includes a centrifugation step. 7. Method to enhance the stability of a pourable water in oil emulsion whereby gas bubbles are incorporated in the aqueous phase of said liquid margarine. |
