RESUMEN
Pterostilbene is a highly researched molecule due to its bioactivity. However, its hydrophobicity limits its application. For this reason, researchers have sought to encapsulate pterostilbene (namely, in oil-in-water emulsion) to increase its availability. Studies are lacking when it comes to the effects of pterostilbene and its concentration at the oil/water interface. This paper discusses the effects of oil types, storage temperature, and pterostilbene concentration on the stability of the emulsions, as well as the interactions between encapsulated pterostilbene and the oil and water phases. Results showed that pterostilbene is present at the oil/water interface, affecting the interfacial tension and consequently the droplet size. It was also shown that encapsulation efficiency is affected by the storage temperature and oil type. Finally, it was proven that, according to oil types and storage temperature, the stability of pterostilbene to light is affected.
