Many oil encapsulation techniques in which particles are used to effectively inhibit oxidation of unsaturated fatty acids have been reported. We have developed a new process using an inkjet nozzle which allows easy control of particle size and morphology and free from oxidation concerns. This process was used to prepare particles of rutin and composite particles composed of glycine and rutin. All particles were spherical in shape and had a relatively uniform particle size distribution. Rutin hollow particles or particles with a bilayer structure of glycine and rutin were selectively produced, depending on the solution used. The particles inhibited the oxidation of the oil, and the retardation effect was constant regardless of the oil. Furthermore, the oxidation rate differed depending on the structure of the particles, which suggests the importance of improving stability by complexation.
