Abstract

Abstract: To supplement the currently used methods for poultry meat shelf life assessment, it might be necessary to develop a technique for rapid headspace analysis of volatiles with no prior sample preparation step. Biogenic amines, in particular cadaverine, are considered meat spoilage indicators. Described in this article are the results of a preliminary investigation of the applicability of proton transfer reaction mass spectrometry in the determination of cadaverine concentration in the volatile fraction of poultry meat samples stored in aerobic conditions. Dispersive liquid-liquid microextraction-gas chromatography-mass spectrometry and determination of total viable bacteria were used as reference methods. It was determined that there is a good correlation (Pearson correlation of 0.96) between the concentration of cadaverine in the headspace of chicken meat samples stored over a period of 5 days and the total viable bacteria count. Based on the results, it can be concluded that the changes of cadaverine concentration in the meat samples' volatile fraction can be successfully monitored with a short time of a single analysis and with no sample preparation.

有氧储存鸡胸肉样品挥发性成分中尸胺的直接测定。

摘要：为了补充目前使用的禽肉保质期评估方法，可能有必要开发一种无需事先准备样品的快速顶空挥发性分析技术。生物胺，特别是尸胺，被认为是肉类腐败的指标。本文介绍了质子转移反应质谱法在测定好氧条件下储存的禽肉样品挥发性成分中尸胺浓度中的适用性的初步研究结果。采用分散液-液微萃取-气相色谱-质谱法和活菌总数测定法作为参考方法。经测定，在储存5天的鸡肉样品的顶部空间中尸胺的浓度与总活菌计数之间存在良好的相关性（Pearson相关性为0.96）。基于这些结果，可以得出结论，在不进行样品制备的情况下，可以在短时间内成功地监测肉类样品挥发性组分中尸胺浓度的变化。图形摘要：

期刊介绍： "Monatshefte für Chemie/Chemical Monthly" was originally conceived as an Austrian journal of chemistry. It has evolved into an international journal covering all branches of chemistry. Featuring the most recent advances in research in analytical chemistry, biochemistry, inorganic, medicinal, organic, physical, structural, and theoretical chemistry, Chemical Monthly publishes refereed original papers and a section entitled "Short Communications". Reviews, symposia in print, and issues devoted to special fields will also be considered.
