Popis: The production of safe foods with little or no artificial preservatives is one of the foremost leading challenges for food manufacturing industries because synthetic antimicrobial agents and chemical food additives can cause severe negative effects on human health. However, there is an ever-increasing interest by consumers towards natural sources that have been aroused recently, and this increased consumer demand for safe food products has forced the food industries to use natural herbal and plant origins preservatives instead of synthetic preservatives for the production of safe foods. Traditionally, essential oils (EOs) obtained from numerous plant sources have been extensively encouraged for their putative health-promoting biological activities. The EOs are composed of complex mixtures encompassing copious individual compounds, which have been extracted by many methods. These diverse compounds display significant biological activities such as antioxidant and antimicrobial through different mechanisms. Nevertheless, their poor solubility in water, oxidation susceptibility, and volatility limit their use. To overcome these constraints, encapsulation is one of the best approaches to preserve the biological activities of EOs and minimize their effects on food sensory qualities. Herein, we have comprehensively enlightened the micro/nanoemulsion loaded with EOs to improve the physical—chemical and microbiological stability of various EOs, and further application of these EOs loaded systems in the food systems. This review confers the importance of EOs in terms of their main components, chemical and biological properties, including mode of action, effectiveness, synergistic effects as antimicrobials, and potential applications in the food system as a preservative.
