“…In consideration of the ageing process, chances in the volatile profile of egg products can be expected. Therefore, among possible analytical techniques, gas chromatography–mass spectrometry could be used for the identification of these changes, in agreement with previous applications in the field of food frauds, ie, tomato cultivars discrimination, honey authenticity, or geographical origin of saffron …”

Egg products' freshness is a crucial issue for the production of safe and high-quality commodities. Up to now, this parameter is assessed with the quantification of few compounds, but the possibility to evaluate more molecules simultaneously could help to provide robust results. In this study, 31 compounds responsible of freshness and not freshness of egg products were selected with a metabolomic approach. After an ultrahigh-pressure liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) analysis, different chemometric models were created to select gradually the most significant features that were finally extracted and identified through HRMS data. Sample lots were collected directly from their arrival at the production plant sites, extracted immediately after, then left at room temperature, and extracted again after 24 and 48 hours (first day and second day, respectively). A total amount of 79 samples was used for the model creation. Furthermore, the same compounds were detected in seven new egg products sample lots not used for the model creation and treated with the same experimental design (total amount of samples, 21). The results obtained clearly demonstrate that these 31 molecules can be considered real freshness or not freshness chemical markers. Furthermore, this UHPLC-HRMS metabolomic approach allows for the detection of a larger set of metabolites clearly related to possible microbial growth over time, which is a relevant point for also ensuring food safety.

“…2. By National Institute of Standard and Technology (NIST) library search, peak 3 and peak 4 were identified to be methyl hexanoate [11] and methyl ( Z )‐3‐hexenoate [10,11], respectively. Considering that MS spectrum of peak 2 was very close to that of methyl ( E )‐2‐hexenoate (1), we assumed that peak 2 might be its Z ‐isomer, methyl ( Z )‐2‐hexenoate.…”

Edited by Ulf-Ingo Flügge Keywords:Methyl (E)-2-hexenoate (Z)-2-Hexenol (Z)-2-Hexenal Jasmonic acid Methyl jasmonate a b s t r a c tThe medicinal herbal plant Achyranthes bidentata (A. bidentata) produces the sweet-odor ester -methyl (E)-2-hexenoate (1) as the major volatile in response to methyl jasmonate (MeJA). Here, we investigated the biosynthetic pathway of methyl (E)-2-hexenoate (1). The common plant precursor (Z)-3-hexenal was only slightly metabolized into methyl (E)-2-hexenoate (1), and its application scarcely enhanced the production of this ester. By contrast, a structurally related alcohol, (Z)-2-hexenol, as well as a deuteride derivative thereof could be efficiently metabolized into methyl (E)-2-hexenoate (1). Thus, we hypothesize that A. bidentata possess a specific pathway for the production of methyl (E)-2-hexenoate (1) from (Z)-2-hexenol in response to MeJA.

“…It should be mentioned that using SPME for extraction of VOCs has many advantages which help to avoid possible derivatization of VOCs (low temperature, addition of additives) and that the conditions used in the present study were similar to those reported by other authors. 5,6,23 Taking into consideration the flavor quality of the Andean landraces, these results provide new VOCs as potential candidates involved in the good flavor perception of tomato fruit. In addition, it is well known that more abundant VOCs no necessarily contribute to the characteristic tomato flavor; 24 hence, these new VOCs must be more intensely studied to be considered relevant in the complex chemistry trivia associated with tomato flavor perception.…”

Traditional tomatoes (Solanum lycopersicum L.) have been mainly selected for their fruit quality and maintained by local farmers in Andean areas of Cuyo and Northwestern Argentina. Volatile organic compounds (VOCs) in mature fruits of Andean tomato landraces were evaluated for the first time using headspace solid phase microextraction (HS-SPME) and gas chromatographymass spectrometry (GC-MS) and combined with classical multivariate analysis. The data sets composed of 101 volatile metabolites were identified in 4 accessions of Andean landraces, one commercial variety and one wild tomato accession (Solanum pimpinellifolium L.). The metabolic profile showed typical VOCs of tomato and 21 new compounds never informed in S. lycopersicum. Andean traditional tomatoes have been shown to be metabolically different from wild species. In addition, some varieties of Andean tomatoes have a different profile of VOCs and are richer than the commercial variety. A different and original metabolic volatile composition found in fruits of Andean tomato landraces of Argentina, in comparison with commercial cultivars, might probably reveals selection based on quality attributes made by local farmers.
