The present invention relates to a water-in-oil emulsion, comprising a continuous hydrophobic phase in which the hydrophilic phase is dispersed, wherein: (i) the emulsion has a total water content in the range of 30% to 95% (w/w); (ii) the emulsion does not comprise an emulsion stabilizer; (iii) the hydrophobic phase has a ratio of lipids to oils in the range of 50% to 96% (w/w); and (iv) the continuous hydrophobic phase is made of lyotropic liquid crystalline nanostructures including 5% to 40% (w/w) water. Furthermore, the present invention relates to a corresponding method for preparing such water-in-oil emulsion, the method comprising: (a) pre-mixing of the hydrophilic phase and the hydrophobic phase at a rotation speed of at least 4.000 rpm and at a temperature of at least 40°C, thus forming a raw emulsion; (b) positioning the raw emulsion in a shear device; and (c) applying a shear rate of at least 4.500 s -1 ; and cooling the emulsion to ambient temperature, thus forming a continuous hydrophobic phase of the emulsion that is made of lyotropic liquid crystalline nanostructures. |
