Application of Proton Transfer Reaction Mass Spectrometer in Analyze of Volatile Organic Compounds in Food

Abstract

Abstract: Volatile organic compounds (VOCs) are the main component of food flavor. Analysis of food VOCs, which reveals a lot of information, is an easy and convenient method and has been a main study trend in food science and technology. As a VOCs detection technique that is gradually becoming an important tool in food analysis, proton transfer reaction mass spectrometry (PTR-MS) has following advantages: the sensibility is relatively high; it has fast responding time; there is no need for pretreatment of the samples and it is very easy to operate. With the help of this innovative technique, measurements of absolute concentration of VOCs can be easily and quickly acquired. The on-line trace gas analysis of VOCs can be achieved in order to monitor fundamental and industrial processes. It facilitates effectively food security supervision, food quality control, and new product development and so on. Firstly, this paper presents the working principle, the basic structure and the development of PTR-MS. Secondly, the application and research status of full mass spectral scanning and real-time monitoring in China and abroad in food industry are summarized in details. Thirdly, in the last part of this paper, a prediction of its development prospect for the further study is carefully made.

Key words: volatile organic compounds(VOCs), food detection, proton transfer reaction mass spectrometry (PTR-MS), full mass spectral scanning, real-time monitoring
