This volume details cutting-edge approaches to harnessing the potential of essential oils (EOs) extracted from food by-products, transforming waste into valuable resources for food preservation, enhanced nutrition, and functional food product development. This comprehensive guide takes readers through a variety of modern extraction techniques, including microwave-assisted, ultrasonic-assisted, enzyme-assisted, and supercritical fluid extraction methods. Written in the format of the Methods and Protocols in Food Science series, chapters list necessary materials and methods for readily reproducible protocols.Authoritative and cutting-edge, Essential Oil Extraction from Food By-Products aims to provide protocols that ensure high yields of essential oils while preserving their bioactive properties, making them ideal for a wide range of food applications.
