摘　　要：核辐照技术是近年来发展很快的一种非热力加工的新技术。它利用电离辐射（主要指钴-60的Y射线、加速器产生的电子束或x-射线）与物质的相互作用所产生的物理、化学和生物效应，对香料香精或其他化妆品进行加工处理，可修饰化妆品分子并降解化妆品中的有害物质，已经被证明是一种有效的提高化妆品安全性及延长保质期的“绿色加工”方法。研究表明，辐照仅引起化妆品分子的微小化学变化，并无放射性残留，对人体无害，安全可靠。与其他众多的加工方法相比，辐照技术具有很多突出优点。Irradiation technology is a novel non-thermal processing technology, which is developing rapidly in recent years. It uses the physical, chemical and biological effects produced by the interaction of ionizing radiation （mainly refers to Co60-y-rays, electron beams produced by accelerator, or X-rays） and materials to process fragrance, flavors or other cosmetics. Irradiation technology can modify molecules and degrade harmful substances in cosmetics, which having been proven to be an effective ＂green processing＂ approach to enhance the safety and to extend the shelf-life of cosmetics. Studies have shown that irradiation only causes chemical changes of cosmetic elements and there is no radioactive residue harmful to humans. Therefore irradiation technology is safe and reliable. Comparing with many other processing methods, it has many outstanding advantages
