Essential Oils in Food Applications

Abstract

Historical use of essential oils (EOs) from Australian native plants for therapeutic and food purposes, both by the indigenous people and the early colonial settlers, have been reported. The use of EOs in food applications is based on the needs of today's consumer looking for wholesome food without chemical preservatives. This green consumerism has also spread to agricultural practices and increasingly there is a demand for the use of environmentally friendly alternatives to replace conventional insecticides. There is also an increasing demand for new flavors in the food and beverage sector and EOs, with their unique and exciting aromas and flavors, can contribute to this market need. However, it is important to note that each geographical region has considerable variability in the types of plants from which EOs are derived. This chapter illustrates this with reference to Australia and covers trends in the use of Australian native EOs in food and agriculture applications.
