The world of meat faces a permanent need for new methods of meat quality evaluation. Researchers want improved techniques to deepen their understanding of meat features. Expectations of consumers for meat quality grow constantly, which induces the necessity of quality control at the levels of slaughtering, meat cutting, and distribution. This article is focused on techniques intended to predict technological and sensory qualities from measurements carried out on fresh intact meat. pH has been measured for a long time, but its on-line determination still progresses through automation. In the laboratory, NMR provides new insights on WHC mechanisms. Image processing has considerably improved the assessment of meat appearance. Developments of techniques for prediction of toughness are in progress, either directly, through ultrasonic analysis or NIR reflectance, or indirectly, through determination of connective tissue content by fluorescence probes. Control of authenticity benefits from the last developments of molecular biology and analytical chemistry. However, implementation of methods for meat quality evaluation has been very limited in the industry. The reasons for that situation are analyzed. Among the techniques recently described, the most promising for large-scale meat quality evaluation are considered to be ultrasonic analysis, image processing and NIR spectroscopy.
肉类行业面临着对肉类质量评估新方法的永久需求。研究人员希望改进技术,以加深对肉类特性的理解。消费者对肉类质量的期望不断增长,这促使在屠宰、肉类切割和分销等层面进行质量控制。本文专注于旨在通过对新鲜完整肉类进行测量来预测技术和感官质量的技术。pH 值已经测量了很长时间,但在线测定仍在通过自动化进行改进。在实验室中,NMR 提供了对水分保持能力机制的新见解。图像处理极大地改进了对肉类外观的评估。通过超声分析或近红外反射率直接进行韧性预测的技术发展,或通过荧光探针测定结缔组织含量间接进行韧性预测的技术发展正在进行中。真实性控制得益于分子生物学和分析化学的最新发展。然而,肉类质量评估方法的实施在行业中非常有限。分析了造成这种情况的原因。在最近描述的技术中,最有希望用于大规模肉类质量评估的技术被认为是超声分析、图像处理和近红外光谱。
