植物精油的纳米胶囊化及其在畜禽生产中的应用

Nanoencapsulation of Plant Essential Oils and Their Application inLivestock and Poultry Production

植物精油是从植物组织中经过蒸馏、超临界流体等方法提取得到的一类天然、易挥发、不溶于水的次生代谢物。将植物精油进行胶囊化处理可以一定程度改善植物精油在畜禽生产应用中强挥发、易降解等局限性,并提高其生物活性,以便更好地提高动物生长性能和健康水平。本文主要针对植物精油纳米胶囊的制备方法及其生物活性和在畜禽生产中的应用进行了综述,为未来制备植物精油胶囊并应用于畜牧生产提供理论依据。

Essential oil is a natural,volatile and water-insoluble secondary metabolite extracted from plant tissues by distillation and supercritical fluid.Encapsulation of essential oils can overcome the limitations of essential oils such as strong volatilization and easy degradation,as well as enhance their bioactivity,in order to improve animal performance and health in livestock and poultry production.This paper mainly reviews the methods of preparing nano-capsules of essential oils,their biological activity and application in livestock production,which provides a theoretical basis for the future preparation of essential oil capsules and their application in livestock production.
