摘　　要：作为四大重要木本油料之一,油茶具有高产量和营养价值等优点。油茶籽油的组成不仅由油茶树品种和种植环境决定,油脂提取条件也会导致茶油成分的差异。由于不饱和脂肪酸含量高,茶油在加工过程中易发生氧化而导致品质下降,因此有必要了解提取方法对茶油成分和品质的影响,并选择合适的包埋技术对茶油进行保护。本文全面概述不同地区和品种茶油组成和含量方面的差异。总体而言,海拔高的地区茶油油酸含量更高,中国西南地区茶油中油酸含量平均水平高于华南、华东和华中地区。通过对不同茶油的提取技术进行分析和比较,发现新兴技术对茶油的提取率较高且对活性成分保留较好,但存在成本昂贵等问题。最后,总结茶油包埋技术的研究进展,对茶油包埋技术的不足之处进行讨论并提出未来展望,以期为茶油的应用和发展提供参考。As one of the four important woody oilseeds,camellia seeds have the advantages of high yield and nutritional value.The chemical composition of camellia seed oil is determined not only by camellia variety and the planting environment but also by extraction conditions.Due to its high content of unsaturated fatty acid,camellia seed oil is prone to oxidative degradation during processing,which leads to quality degradation.Therefore,it is necessary to understand the effects of different extraction methods on the chemical composition and quality of camellia seed oil and choose the suitable encapsulation method to protect it.This paper provides a comprehensive overview of the differences in the composition and content of camellia seed oil from different regions and varieties.In general,the oleic acid content of camellia seed oil is higher in high-altitude regions.The average level of oleic acid in camellia seed oil from Southwest China is higher than that in South China,East China,and Central China.Compared with traditional extraction techniques for camellia seed oil,emerging extraction techniques are superior in terms of extraction efficiency and retention of bioactive constituents but have some drawbacks such as higher costs.Finally,this review summarizes the latest advances in encapsulation technologies for camellia seed oil,discusses their deficiencies,and concludes with an outlook on future prospects,with a view to providing a reference for the application and development of camellia seed oil.
