迷迭香提取物的制备及抗氧化、抑菌活性研究进展

迷迭香是重要的经济作物，其提取物中含有酚酸类、黄酮类、萜类等多种生物活性物质，具有抗氧化、抑菌等重要的生理功能，因此可作为天然抗氧化剂、天然抑菌剂应用于生产中。本文综述了迷迭香提取物目前采用的提取、纯化方法，提高提取物稳定性所应用的微胶囊技术、纳米颗粒载体技术和复合涂膜技术。重点讨论了迷迭香提取物的抗氧化、抑菌活性，以及在肉类制品、蔬菜水果、油脂、饮料等加工过程中的具体应用。最后对迷迭香提取物的不足和后续研究进行了讨论与展望，为迷迭香提取物的进一步推广应用提供参考。

Research Progress in Preparation,Antioxidant and Antibacterial Activities of Rosemary Extract

Rosemary is an important economic crop. Its extract contains phenolic acids, flavonoids, terpenes and other biologically active substances. It also has antioxidant and antibacterial functions, so it can be used as a natural antioxidant and bacteriostatic agent in production. In this paper, extraction and purification methods of rosemary, microcapsule technology, nanoparticle carrier technology and composite coating are reviewed, in order to improve the stability of the extract. The antioxidant and antibacterial activities of rosemary extract and its application in meat products, vegetables, fruits, oils and beverages are discussed. Finally, application deficiencies and potential for future research and promotion of rosemary extract are discussed.
