Scientists from University of Hull in UK and Unilever Research in The Netherlands have developed novel micro‐ampoules made from edible materials, having multiple compartments loaded with oils. The micro‐ampoules are prepared using a single‐step, in‐shear solvent‐attrition liquid–liquid dispersion technique, allowing control of particle morphology, as described by V. N. Paunov et al. on p. 2599. Due to their shape, size and surface properties they can adsorb at oil–water or air–water interfaces and could have a dual functionality for foam or emulsion stabilization and encapsulation and delivery simultaneously. Such micro‐ampoules can find applications in the pharmaceutical, nutraceutical, personal care and food industries.
