Study TitleUntargeted Metabolomics for fruit juice authentication
Study SummaryUse of Information Dependent Acquisition mass spectra and Sequential Window Acquisition of all Theoretical fragment-ion mass spectra for fruit juices metabolomics and authentication. LC-MS based untargeted metabolomics are the main untargeted methods used for juice metabolomics to solve the authentication problem faced in fruit juice industry. Objectives To evaluate the performances of different untargeted metabolomics methods on fruit juices metabolomics and authentication, orange and apple fruit juices were selected for this study. Methods IDA-MS and SWATH-MS based on UHPLC-QTOF were used for the metabolomics and authenticity determination of apple and orange juices, including the lab-made samples of oranges (Citrus sinensis Osb.) from Jiangxi Province, apples (Malus domestica Borkh) from Shandong Province, and different brands of commercial orange and apple juice samples from markets. Results IDA-MS and SWATH-MS could both acquire numerous MS1 features and MS2 information of juice components, while SWATH-MS excels at the acquisition rate of MS2. Distinctive separation between authentic orange juice and not authentic orange juice could be seen from principal component analysis and hierarchical clustering analysis based on both IDA-MS and SWATH-MS. After analysis of variance, fold change analysis and orthogonal projection to latent structures discriminant mode, 53 and 46 potential markers were defined by IDA-MS and SWATH-MS (with 77.4% and 100% MS2 acquisition rate) separately. Subsequently, these potential markers were putatively annotated using general chemical databases with 6 more annotated by SWATH-MS. Furthermore, 7 of the potential markers, l-asparagine, umbelliferone, glucosamine, phlorin, epicatechin, phytosphingosine and chlorogenic acid, were identified with standards. For the consideration of model simplicity, two determined makers (umbelliferone and chlorogenic acid) were selected to construct the DD-SIMCA model in commercial samples because of their good correlation with apple adulteration proportion, and the sensitivity and specificity of the model were 100% and 95%. Conclusion SWATH-MS excels at the MS2 acquisition of juice components and potential markers. This study provides an overall performance comparison between IDA-MS and SWATH-MS, and guidance for the method selection on fruit juice metabolomics and juice authenticity determination. Two of the potential markers determined, umbelliferone and chlorogenic acid, could be used as apple juice indicators in orange juice.

MS ID:MS002138
Analysis ID:AN002294
Instrument Name:ABI Sciex 6600 TripleTOF
Instrument Type:QTOF
MS Type:ESI
MS Comments:Mass spectrometric analysis was performed with a Q-TOF MS (TripleTOF 6600, SCIEX, Redwood City, CA, USA) operating in the positive ion mode using a DuoSpray ion source. TOF MS scan and product ion scan for each sample were acquired by two different methods (including the QC samples): IDA-MS and SWATH-MS. The instrument was operated in the high sensitivity mode for product ion scan, and automatically calibrated every 6 sample injections using APCI positive calibration solution delivered via a calibration delivery system (SCIEX, Redwood City, CA, USA). The other experiment parameters for TOF MS scan were set as follows: curtain gas, 25 (arbitrary units); ion source gas 1, 50 (arbitrary units); ion source gas 2, 50 (arbitrary units); temperature, 500 °C; ion spray voltage floating, 5.5 kV; declustering potential, 60 V; collision energy, 10 eV. The IDA (cycle time 545 ms) was composed of a TOF MS scan (accumulation time, 50 ms; CE, 10 eV) and 15 dependent product ion scans (accumulation time, 30 ms each; CE, 35 eV) in the high-sensitivity mode with dynamic background subtraction. The SWATH (cycle time 545 ms) was composed of a TOF MS scan (accumulation time, 50 ms; CE, 10 eV) and a series of product ion scans (accumulation time, 30 ms each; CE, 35 eV) of 15 Q1 windows of 60 Da from m/z 100−1000 in the high-sensitivity mode. Mass ranges of TOF MS was m/z 100-1000 and product ion scans was m/z 50−1000 for both these two methods. QC samples were acquired throughout the run to monitor the instrument stability. The LC−MS data was acquired using Analyst TF 1.7.1 (SCIEX, Redwood City, CA, USA). For the fruit juice metabolomics study evaluation, UHPLC-Q-TOF data of apple juices and orange juices were processed by MarkerView 1.3.1 (SCIEX, Redwood City, CA, USA). The parameters were set as follow: RT tolerance 0.5 min, mass tolerance 10 ppm, minimum RT peak width 6 scans, noise threshold 100. And the list of MS1 features was exported for further analysis using Microsoft Office Excel 2016 (Microsoft Corporation, Redmond, Washington, USA). The extracted MS1 feature with detection rate greater 80% among the five replicate injections of QC sample were defined as detected ones. To compare the MS2 quantity and quality acquired by IDA-MS and SWATH-MS in the fruit juice metabolomics study, the data files were processed by PeakView 2.2 for in-house MS/MS phenol library matching, and the freely available MS-DIAL software Version 3.40 (http://prime.psc.riken.jp/Metabolomics_Software/MS-DIAL/) for MassBank of North America (MONA, http://mona.fiehnlab.ucdavis.edu/) library (after filtering based on instrument type) putative annotation. And the annotation level is level 2 (Putatively annotated compounds) according to Metabolomics Standards Initiative standards. MS-DIAL is designed as a universal program for MS data processing that supports any mass spectrometry approach. It is vendor independent and supports data conversion from file formats of many instrument manufacturers. It also supports any data acquisition method, from nominal or accurate mass analysis to data-dependent or data-independent MS/MS. For the fruit juice authenticity study comparison, the UHPLC-Q-TOF data of orange juices, apple juices and orange juices adulterated with different proportions (1%, 2%, 5%, 10%, 15% and 20%) of apple juice acquired by IDA-MS and SWATH-MS were processed by MarkerView Version 1.3.1, and the parameters were set as in the fruit juice metabolomics. The exported MS1 peak list was analyzed by Microsoft Office Excel 2016 to filter the MS1 features whose detection rate were lower than 80% or relative standard deviations of the quality control group were higher than 30%. Then the table was uploaded to Metaboanalyst (https://www.metaboanalyst.ca/), and the missing values were replaced by a small value, none filtering for features was used. After log transformation and auto scaling, principal component analysis (PCA) and hierarchical clustering analysis (HCA), student’s t-test, as well as fold change analysis were conducted. And SIMCA 14.1 (Umetrics, Sweden) was used for the orthogonal projection to latent structures discriminant analysis (OPLS-DA) mode construction. The MS2 spectra of potential markers were exported from MarkerView 1.3.1 to MS-FINDER software (version 3.16) for the potential marker annotation by matching with the in-built databases, such as Massbank, GNPS, HMDB and FooDB. And the MoNA database from Massbank of North American (http://mona.fiehnlab.ucdavis.edu) was downloaded and searched by the MS-FINDER simultaneously. The METLIN database was searched using MassHunter PCDL Version B.07.00 (Agilent, USA). The parameters, MS1 tolerance and MS2 tolerance, were set as 10 ppm and 15 ppm. The standard confirmation of potential markers was conducted by comparing the retention time as well as the MS2 fragments. For the potential marker test and model construction/validation in commercial samples, the peak area table of the potential markers was exported from MultiQuant 3.0.3 (SCIEX, Redwood City, CA, USA), and imported to the Excel tool, DD-SIMCA, for model construction and validation.
