“…All mass peaks found significantly different at least in one of the time point ( P < .01) were reported by starting from m / z = 41.038 and by taking a concentration threshold of at least 0.1 ppbV. Twenty‐eight mass peaks were tentatively identified on the basis of their sum formula, fragmentation pattern, and literature data …”

Rapid and noninvasive quality control of anhydrous milk fat by PTR‐MS: The effect of storage time and packaging

et al. 2018

In this study, proton transfer reaction-mass spectrometry (PTR-MS), coupled with a time-of-flight mass analyzer and a multipurpose automatic sampler, was evaluated as a rapid and nondestructive tool for the quality control of anhydrous milk fat. Anhydrous milk fats packed in cardboard and bag-in-box were compared during refrigerated shelf life at 4°C for 9 months. Anhydrous milk fat samples were taken at 120, 180, and 240 days and measured by PTR-MS during storage at 50°C for 11 days. Univariate and multivariate data analysis were performed in order to classify samples according to the packaging type and compare aromatic profiles. Markers related to both packaging and storage duration were identified, and all stored samples were clearly distinguishable from reference fresh samples. Significant differences in some key butter aroma compounds such as 2-pentanone, 2-heptanone, 2/3-methylbutanal, acetoin, and butanoic acid were observed between different types of packaging. During the refrigerated storage, differences related to packaging are more evident, while during the storage at 50°C, the fat oxidation induced by the high temperature becomes the most relevant phenomenon independently of the packaging type. These results indicate the importance of avoiding anhydrous milk fat storage at 50°C for long times during industrial production processes. All together data demonstrated the viability of PTR-MS as a rapid and high-sensitivity tool in agroindustry quality control program.

“…In addition, this technique does not require any sample pre-treatment such as drying or pre-concentration and is thus well suited for oxygenated VOCs, which cannot be quantified from canister samples used in a traditional chemical analysis method. PTR-MS has been widely used in atmospheric, food, environmental science, forensic investigation and medical research (Blake et al, 2009;Boscaini et al, 2004;Filella and Penuelas, 2006;de Gouw and Warneke, 2007;Granitto et al, 2007;Hewitt et al, 2003;Jobson et al, 2005;Kato et al, 2004;Lindinger et al, 1998Lindinger et al, , 2001Lindinger et al, , 2008Lirk et al, 2004;Mayr et al, 2003;Steeghs et al, 2004;Van Ruth et al, 2007;Wang and Stout, 2007;Warneke et al, 2003;Wehinger et al, 2007;Whyte et al, 2007). On the other hand, there have been rare studies in the field of indoor air quality utilizing this technique with a few exceptions (Bunge et al, 2008;Fang et al, 2008;Weschler et al, 2007;Wisthaler et al, 2007).…”

Determination of material emission signatures by PTR-MS and their correlations with odor assessments by human subjects

et al. 2010

View full text Add to dashboard Cite

The study shows that unique emission patterns may exist for different types of building materials. These patterns, or signatures, can be established by using PTR-MS, an online monitoring device. The sum of selected major individual VOC odor indices determined by PTR-MS correlates well with the acceptability of air quality assessed by human subjects, and hence provides a feasible approach to assessing perceived indoor air quality. This online assessment will open a new gate in understanding the role of VOC emissions from building materials on perceived air quality, forming a good foundation to develop real-time or near real-time methods for standard material emission testing and labeling, quality control of emissions from materials, and assessing the acceptability of air quality in buildings.

“…The application of this technique usually leads to a fingerprint of the emission of VOCs profile from food samples for the study of quality, fermentation, ripening, and processing. As an example, PTR-MS has been used to investigate volatile fingerprints of orange juices subjected to different thermal and pressure treatments [35], classification of milk fats of different qualities [36], prediction of freshness of bread [37], classification of infant formulas according to different brands and physical forms [38], and prediction of sensory profiles of coffee [39]. Special importance has been given to wine [40,41] owing to the economic importance of this industry.…”

The role of direct high-resolution mass spectrometry in foodomics

et al. 2015

View full text Add to dashboard Cite

Foodomics has been defined as a global discipline in which advanced analytical techniques and bioinformatics are combined to address different questions in food science and nutrition. There is a growing number of works on the development and application of non-targeted omics methods in foodomics, which reflects that this emerging discipline is already considered by the scientific community to be a valuable approach to assess food safety, quality, and traceability as well as for the study of the links between food and health. As a result, there is a clear need for more rapid, high-throughput MS approaches for developing and applying non-targeted studies. Nowadays, direct MS analysis is one of the main choices to achieve high throughput, generating a set of information from the largest possible number of samples in a fast and straightforward way. The use of high- and ultrahigh-resolution MS greatly improves the analytical performance and offers a good combination of selectivity and sensitivity. By using a range of methods for direct sample introduction/desorption/ionization, high-throughput and non-target analysis of a variety of samples can be obtained in a few seconds by HRMS analysis. In this review, a general overview is presented of the main characteristics of direct HRMS-based approaches and their principal applications in foodomics.
