The encapsulation of bioactive compounds in nanoemulsions is an innovative technique that aims to improve the solubility, stability and bioavailability of substances with functional properties, such as antioxidants, antimicrobials and anti-inflammatories. Nanoemulsions, formed by droplets with sizes smaller than 200 nm , are capable of increasing the absorption of bioactive compounds by the organism and protecting these compounds from degradation during storage and processing. This article reviews the methods of preparing nanoemulsions, such as high-pressure homogenization and ultrasound, and...

A review of the literature on the antioxidant activity of essential oils reveals their significant potential in protecting against oxidative stress. Several studies demonstrate that bioactive compounds present in these oils, such as flavonoids and terpenes, have antioxidant properties that neutralize free radicals. Furthermore, antioxidant efficacy varies according to the origin and chemical composition of the essential oils. Applications include not only food preservation, but also benefits in pharmacological and therapeutic contexts. Thus, research on essential oils shows promise,...
