Artificial oil bodies

A method of producing artificial oil bodies, the method comprising

• i) obtaining an extract of a plant comprising oleosin, wherein the extract is plant meal,
• ii) at least partially purifying protein from the extract, wherein the protein comprises oleosin, and
• iii) mixing the protein comprising oleosin, with surfactant and oil comprising polyunsaturated fatty acids with four or more double bonds to produce the artificial oil bodies.
