In addition to being used in food, fuel and lubricants, vegetable oils are promising in many other applications such as food additives, nutritional supplements, cosmetics and biomedicine; however, their low oxidative stability can limit their use. Microencapsulation is a well-established method for the preservation of oil against degradation, controlled release of active ingredients, protection against external factors during storage, and enhanced durability. In this article, microencapsulation methods for vegetable oil are reviewed, including physical methods (spray-drying and freeze-drying), physicochemical methods (complex coacervation, ionic gelation and electrostatic layer-by-layer deposition), and chemical methods (interfacial/in situ polymerization). This article also provides information on the principles, parameters, advantages, disadvantages and applications of these methods., Biljna ulja se osim u prehrani te kao goriva i maziva, mogu koristiti kao dodaci hrani, nutraceutici, u proizvodnji kozmetike i biomedicini, no primjena im je ograničena zbog slabe oksidacijske stabilnosti. Mikroinkapsulacija je uobičajena metoda zaštite ulja od razgradnje i vanjskih čimbenika tijekom skladištenja, kojom se kontrolira otpuštanje aktivnih sastojaka i produljuje trajnost ulja. U ovom je radu dan kratki pregled metoda mikroinkapsulacije biljnih ulja, uključujući fizikalne (sušenje raspršivanjem i zamrzavanjem), fizikalno-kemijske (kompleksna koacervacija, ionsko geliranje i slojeviti elektrostatski premazi) i kemijske (međufazna i in situ polimerizacija) postupke. Osim toga, ovaj rad donosi informacije o principima, parametrima, prednostima i nedostacima, te mogućim primjenama ovih metoda.
