Abstract Baijiu, a conventional fermented beverage with thousands history, plays a crucial part in physical health of people and social culture in China. The application of high-throughput screening and confirmation of flavor components in the field of authenticity identification and potential function has attracted more and more attention and interest of researchers. With more attention to health, pesticides residues, phthalates, biogenic amines and other hazardous substances remained in Baijiu...

Abstract A precise and unambiguous quantitative strategy for six biogenic amines in dry fermented mutton sausage with liquid chromatography tandem quadrupole Orbitrap mass spectrometry was developed to investigate the inhibitory effects of star anise, amomum tsao-ko, clove, cassia, fennel, bay leaf, and nutmeg on the accumulation of biogenic amines. Compared the data-dependent MS2 fragmentation (dd-MS2), variable data-independent acquisition (vDIA), and multiplex data-independent acquisition (mD...

Abstract Classification of Feng-flavor Baijiu considering aging category was furnished with a comprehensive fingerprinting strategy which used UPLC-Orbitrap and foodomics, and the most discriminant 29 compounds related to aging, 15 organic acids, 8 esters as well as some carbonyl compounds were discovered. Increase of aromatic organic acids, decline of carcinogenic dibutyl phthalate and generation of numerous aromatic substances in Baijiu were caused by irradiation until the system reached a rel...

Abstract During a microbial fermentation process, the chemical composition of Fu brick tea changed substantially. To better profile the unique changes of metabolites and lipids in Fu brick tea at different fermentation stages, a multifaceted strategy combining untargeted foodomics with UHPLC-Q-Orbitrap analysis was developed. The discriminative tea metabolites and lipids were determined by statistical analysis and online database matching. A total of 12 characteristic components (3 metabolic and...

Abstract Antioxidant nutraceuticals functional characteristic science is a challenging field for combining sensitivity and comprehensiveness. A untargeted screening and quantification method based on ultra-high performance liquid chromatography coupled to Quadrupole-Orbitrap high resolution mass spectrometry has been developed for determination of multiple classes of flavonoids in eight-three nutraceuticals samples. The data acquisition is based on a non-target approach of sequential full scan a...

Abstract Cordyceps sinensis is a traditional Chinese food. A high-throughput screening and quantitative method based on hydrophilic interaction chromatography coupled to quadrupole/Orbitrap high resolution mass spectrometry has been proposed for the joint measurement of nucleosides and their corresponding nucleotides in thirty-two Cordyceps sinensis samples. A total of thirty-two natural samples from six regions were enrolled. A multiple-step analysis strategy, including features extraction, noi...

Abstract A dynamic headspace (DHS) with DVB/CAR/PDMS trapping materials was coupled to a gas chromatography-mass spectrometry for the separation and identification of volatile-flavor compounds in bos grunniens (yak) milk. The principal components analysis coupled with response surface methodology optimized the main variables of the device (10 g sample quality, 5 min desorption time, 3.0 g adding sodium chloride, 72 °C extraction temperature, 28 min pre-equilibrium time and 86 min extraction time...

Abstract A reliable Fisher discriminant model was established which was able to analyze the aroma component in milk, dairy products, flavors and fragrance, and applied on its variety identification. Foodomics was applied on screening of flavor components in 1093 dairy products and flavor samples in this study. Stepwise discrimination was used to screen the components of the dairy products and flavor samples that had a significant effect on the classification results, and discriminant function an...

Abstract A new multi-analytical strategy was developed to screen mycotoxins and their transformation products in nutraceuticals from green tea. Seven class mycotoxins were determined using a fully automated on-line extraction procedure followed by ultrahigh-performance liquid chromatography coupled to high resolution mass spectrometry. This multi-analytical methodology has been explored providing an entire spectrum of fragment ion peaks for each mycotoxin, which allows unbiased high-throughput s...
