Migration of non volatile compounds from twenty six PP films used as food contact materials has been studied in four simulants (ethanol 95% and 10%, acetic acid 3% and Tenax ®) and analyzed by UPLC-MS/QTOF. Seventy six compounds have been identified, where 76% of them were non-intentionally added substances (NIAS) coming from degradation of additives used, such as methyl or ethyl or hexyl-3

UPLC-QTOF/MS-Based Nontargeted Metabolomic Analysis of Mountain- and Garden-Cultivated Ginseng of Different Ages in Northeast China. by. Hailin Zhu. ,.

Authors Camila 2020-11-23 2019-10-21 2019-11-26 The analyses were carried out by UPLC-MS-QTOF. The use of high resolution mass spectrometry allowed the structural elucidation of these compounds and their correct identification. The main oligomers identified were cyclic as well as lineal from the first, second, and third series. Accurate Mass Structural Elucidation of Biomarkers in Yeastolate by UPLC/MS (qTof) and Composition Profiling by Multivariate Analysis to Reduce Variability in Cell Culture Media Barry Drew, Kim Schrag, and Chandana Sharma Cell Sciences and Development, SAFC/Sigma … 2019-11-26 A benchtop QTof mass spectrometer incorporating the XS Collision Cell for enhanced sensitivity and selectivity, resulting in the highest quality, most comprehensive qualitative information together with the ultimate in quantitative performance.

Keywords: Dendrobium officinale; anthocyanin; UPLC-MS-QTOF; anthocyanidin synthase 1. Introduction Dendrobium officinale (Chinese name: Tie-pi-shi-hu) is an edible perennial orchid plant that has commonly been employed as a functional food in China and other Asian countries for …

Cyperus has been commonly used as a multi-use medicinal plant in folk medicine worldwide. The objectives of our study were to determine the different metabolites in the Cyperus conglomeratus Rottb. methanol extract, and to assess its in vivo gastroprotective effect in ethanol-induced gastric ulcer model in rats. An ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC–qTOF-MS/MS) method was developed and validated for the simultaneous determination of glycyrrhizin and glycyrrhetic acid. The Magnolia denudata flower is used to prepare tea and is often fermented to improve its flavor. Herein, fresh, aged, and browned M. denudata flower extracts were characterized using ultra performance liquid chromatography coupled with a hybrid quadrupole orthogonal time-of-flight mass spectrometer (UPLC-Q-TOF/MS/MS). Unlike any other exact mass MS/MS benchtop system on the market, Xevo QTof mass spectrometer from Waters Corp.

FREC SERVICES. The Flavor Research and Education Center (FREC) works to understand drivers of flavor perception and, ultimately, food choice. We have built a holistic analytical platform that combines our extensive expertise with modern and advanced instrumentation to investigate and address unique and challenging aspects of flavor discovery.
