Oregano Essential Oils

Abstract

Essential oils (EOs) are aromatic products made from a combination of components extracted from plant materials used in food, cosmetics, and medicine, among several other applications. EOs are extracted using various extraction methods from the bark, seeds, leaves, peel, buds, flowers, and other components of medicinal plants. Techniques used to extract EO include steam distillation, solvent-assisted extraction, hydrodistillation, ultrasonic extraction, supercritical fluid extraction, and solvent-free microwave extraction. EO affects the intestinal health and growth efficiency of different animal species. EO has been reported to improve pancreatic amylase, trypsin, and maltase levels and increase digestibility. EO has antioxidant action, lowers lipid oxidation in meat, and enhances shelf-life. The present chapter summarizes some of the beneficial effects of oregano EO on poultry production and health.
