Metabolomics for empirical delineation of the traditional Korean fermented foods and beverages
Singh, D.,Lee, S.,Lee, C.H. Elsevier Trends Journals 2017 Trends in food science & technology Vol.61 No.-
<P>Key findings and conclusions: This review outlines the metabolomic perspectives for the traditional Korean fermented foods and beverages. We discuss the current trends towards the application of metabolomics and related methodologies to probe their metabolite contents and functionality. Moreover, the crucial bottlenecks associated with fermentative bioprocess and microbial transformations are also addressed in the context of artisanal and industrial manufacturing processes. Further, the article proposes a rational metabolomic approach towards the discernment of palatability and insalubrities associated with fermented foods. (C) 2017 Elsevier Ltd.

Analytical capabilities of mass spectrometry imaging and its potential applications in food science
Li, B.,Dunham, S.J.B.,Dong, Y.,Yoon, S.,Zeng, M.,Sweedler, J.V. Elsevier Trends Journals 2016 Trends in food science & technology Vol.47 No.-
<P>Background: Mass spectrometry imaging (MSI) is an untargeted and label-free chemical imaging technique that allows for the analysis of hundreds to thousands of molecules in a single experiment. Over the last two decades, MSI has become common in the medicinal, pharmaceutical, and botanical research communities, but has been applied less frequently in food science research. As an emerging 'molecular microscope', MSI offers unparalleled advantages for exploration of the spatio-chemical information from various food materials. It allows researchers to localize biomarkers of food origin and authenticity, characterize nutrients or chemical contaminants affecting human health, and ultimately, extend our understanding of food factors at the molecular level. Scope and approach: This review focuses on the predominant MSI ionization technologies and summarizes their application to studies involving food science, including the imaging of food metabolites, elements, naturally occurring toxic constituents, and exogenous contaminates. Technical considerations associated with sample preparation, MALDI matrix choice and application, data processing, analyte identification, and spatial resolution are discussed, as are the future outlooks for MSI in food science. Key findings and conclusions: MSI offers unparalleled chemical specificity for multiplexed analysis of the spatial distribution of nutrients, elements, and contaminants in food; information that is difficult or impossible to acquire with traditional staining or label-based methodologies. The unique spatio-chemical insights acquired with MSI have proven essential for understanding metabolic origin and change, and for visualization of exogenous substances having relevance to food quality and safety.

Applications of cold plasma technology for microbiological safety in meat industry
Misra, N.N.,Jo, C. Elsevier Trends Journals 2017 Trends in food science & technology Vol.64 No.-
<P>Key findings and conclusions: Majority of the studies have demonstrated the successful application of cold plasma for decontamination of meat and meat products. With rapid on-going developments in plasma science, plasma technologies could be used to replace conventional decontamination technologies in meat industry in the near future. (C) 2017 Elsevier Ltd.
