1. An emulsion comprising an internal phase dispersed in a continuous external phase and cellulose filaments located at the interface of the internal phase and the external phase, wherein the emulsion comprises 50% in volume or more of the internal phase at 25° C., wherein the cellulose filaments are heterogeneous in mass and dimension consisting of fine fibrils ranging from 44 microns to 70 microns in length and 30-100 nanometers in width, and large fragments ranging from 496 microns to 3520 microns in length and 9-23 microns in width.
