Classification of carcasses at the slaughter line allows an optimisation of its processing and differentiated payment to producers. Boar taint is a quality characteristic that is evaluated in some slaughter plants. This odour and flavour is mostly present in entire males and perceived generally by sensitive consumers as unpleasant. In the present work, the methodologies currently used in slaughter plants for boar taint classification (colorimetric method and sensory quality control-human nose) and the methodologies that have the potential to be implemented on/at the slaughter line (mass spectrometry, Raman and biosensors) have been summarized. Their main characteristics are presented and an analysis of strengths, weaknesses, opportunities and threats (SWOT) has been carried out. From this, we can conclude that, apart from human nose, the technology that arises as very promising and available on the market, and that will probably become a substitute for the colorimetric method, is the tandem between the laser diode thermal desorption ion source and the mass spectrometry (LDTD-MS/MS) with automation of the sampling and sample pre-treatment, because it is able to work at the slaughter line, is fast and robust, and measures both androstenone and skatole.
在屠宰线上对胴体进行分类有助于优化其加工过程，并实现对生产者的差异化支付。公猪异味是一些屠宰厂会评估的一项质量特性。这种气味和风味大多存在于未阉割的公猪中，敏感的消费者通常会觉得它令人不悦。在本研究中，总结了目前屠宰厂用于公猪异味分类的方法（比色法和感官质量控制——人工嗅觉）以及有可能在屠宰线上实施的方法（质谱分析、拉曼光谱和生物传感器）。介绍了它们的主要特点，并进行了优势、劣势、机会和威胁（SWOT）分析。由此我们可以得出结论，除了人工嗅觉外，市场上出现的非常有前景且可用的、可能会替代比色法的技术是激光二极管热解吸离子源与质谱联用（LDTD-MS/MS）并实现采样和样品预处理自动化，因为它能够在屠宰线上工作，速度快且性能稳定，并且能够同时检测雄烯酮和粪臭素。
