摘要近年来，我国肉类加工行业发展迅猛，自动化和智能化水平逐渐提高，多种肥瘦比例检测技术被应用到肉制品加工和屠宰行业。双能X射线吸收法（dual energy X-ray absorptiometry，DXA）是解决肉制品在线肥瘦比例检测的最佳方法之一，具有精准度高、耗时短、可以对胴体全身进行检测的优势。本文比较当前各种肥瘦比例检测技术的特点，介绍DXA的概念、测量方式，重点探讨DXA在肥瘦比例测定中的应用和研究进展，通过对研究现状、设备类型和存在问题的分析，讨论未来该技术应用的发展方向。
Abstract：The meat processing industry in China has developed rapidly in recent years as it has become increasingly automated and intelligent. Various technologies for the measurement of fat-to-lean ratio have been applied to the slaughter and meat processing industry. Dual-energy X-ray absorptiometry (DXA) is one of the best methods for the online measurement of fat-to-lean ratio, which is highly accurate, efficient and also suitable for whole carcasses. In this paper, we compare the characteristics of the current methods for measuring fat-to-lean ratio, and introduce the concept and working principle of DXA with a special focus on recent progress in the application and research of this technology in the measurement of fat-to-lean ratio. Moreover, we discuss existing problems and future directions for the application of this technology.
