Nanocapsule technology is a very prospect emerging technology
which have its own uniqueness and superiority in different fields. summarize domestic and foreign literature review of nanocapsule technology in plant essential oils in recent years. Nano-microcapsule technology transforms liquid plant oils to solid and effectively controls aromatic plant oil to slow release propertie to extend the fragrant time. it's widely used in food
cosmetics and textiles industries. The application of nanocapsule technology in plant essential oils shows that plant essential oils have great potential market value. However
a great deal of work needs to be devoted to the research of new preparation methods of plant essential oil nanocapsules
and a complete and practical system is established to evaluate the properties of nanocapsules. The purpose of this study is to find low price environmental friendly and non-toxic wall materials to obtain more application value of nanocapsule material.
