微胶囊化植物精油在果蔬保鲜包装中的应用

植物精油的天然抑菌性和抗氧化活性使其在果蔬保鲜领域有着广泛的应用前景。然而，植物精油具有强烈气味、易挥发等缺点，应用效果不佳。微胶囊技术可以掩盖精油的强烈气味，保持其化学稳定性，且具有缓释效果，可以更好地发挥植物精油在果蔬保鲜包装方面的优良性能。介绍了植物精油的抑菌活性、抗氧化活性以及植物精油微胶囊的芯材、壁材和常用的制备方法，对植物精油微胶囊保鲜剂控释包装、复合保鲜薄膜包装和可食性涂膜包装在果蔬保鲜包装方面的研究现状进行综述，以期为微胶囊化植物精油在果蔬保鲜包装方面的进一步研究与应用提供参考。

Application of Microencapsulated Plant Essential Oil in Fruit and Vegetable Preservation Packaging

The natural antibacterial and antioxidant activity of plant essential oil make it have a wide application prospect in the field of fruit and vegetable preservation. However, plant essential oil has some disadvantages such as strong odor and volatility, and the application effect is not good. Microcapsule technology can cover the strong smell of essential oils, maintain the chemical stability, and have a slow-release effect, which can better play the excellent role of plant essential oils in the preservation and packaging of fruits and vegetables. The antibacterial and antioxidant activities of plant essential oils were introduced, as well as the core materials, wall materials and common preparation methods of plant essential oil microcapsules. The research status of plant essential oil microcapsule fresh-keeping agent controlled-release packaging, composite fresh-keeping film packaging and edible film packaging in fruit and vegetable preservation packaging was reviewed and analyzed, in order to provide reference for further research and application of microencapsulated plant essential oil in fruit and vegetable preservation packaging.
