“…Under low-temperature stress, the metabolome L. vannamei hepatopancreas were significantly altered, and the changes of significant differential metabolites showed a influence on the cold tolerance of L. vannamei. Chang et al [4] found 37 metabolites markers in Chilean and Norwegian salmon through untargeted metabolomics that can be used for food traceability. Yu et al [5] investigated the metabolic changes in Solenocera melantho during refrigerated storage after electron beam irradiation, there were two potential biomarkers, namely phosphatidylcholines and hypoxanthine, were obtained in the shrimp muscle.…”

Quality deterioration induced by microbial community in Litopenaeus vannamei during superchilling storage were demonstrated in this study. In this study, 6 microorganisms were identified as the biomarkers by 16S rDNA sequencing and 71 differential metabolites were identified by untargeted metabolomics. The correlation analysis between microorganisms and differential metabolites revealed that Oceanicaulis, Aliihoeflea, Prauserella, Chelativorans and Pseudoalteromonas had the potential to be the important microorganisms of deterioration of superchilled shrimp. Moreover, the spearman correlation analysis revealed that L* value had highly significant correlation with Shewanella (P < 0.01), and TBA value, TVC value total sulfhydryl content, TCA-soluble peptide and Ca 2+ -ATPase activity showed significantly correlation with Oceanicaulis, Prauserella, Chelativorans, Aliihoeflea and Pseudoalteromonas (P < 0.05). This study offers a better understanding for mechanisms behind quality degradation induced by microorganisms, which may help the quality maintaining of Pacific white shrimp during superchilling storage.

“…Fingerprinting is an untargeted method to screen all unexpected chemicals, offering fast, cost-effective, and reliable characterization of overall chemical compositions of complex sample matrices. As fingerprints of different samples summarize numerous unspecific targets or data points, limiting the possibility of random similarities, subtle but important deviations of complex matrices can be discriminated. , Nonetheless, fingerprinting methods are still taking initial steps to meet the practical needs. To succeed in the application of fingerprinting methods, substantial efforts must be invested to establish adequate fingerprint databases and threshold limits that could correlate similar fingerprints and delimitate different fingerprints …”

Biogenic Solution Map Based on the Definition of the Metabolic Correlation Distance between 4-Dimensional Fingerprints

Accurate discrimination and classification of unknown species are the basis to predict its characteristics or applications to make correct decisions. However, for biogenic solutions that are ubiquitous in nature and our daily lives, direct determination of their similarities and disparities by their molecular compositions remains a scientific challenge. Here, we explore a standard and visualizable ontology, termed "biogenic solution map", that organizes multifarious classes of biogenic solutions into a map of hierarchical structures. To build the map, a novel 4-dimensional (4D) fingerprinting method based on data-independent acquisition data sets of untargeted metabolomics is developed, enabling accurate characterization of complex biogenic solutions. A generic parameter of metabolic correlation distance, calculated based on averaged similarities between 4D fingerprints of sample groups, is able to define "species", "genus", and "family" of each solution in the map. With the help of the "biogenic solution map", species of unknown biogenic solutions can be explicitly defined. Simultaneously, intrinsic correlations and subtle variations among biogenic solutions in the map are accurately illustrated. Moreover, it is worth mentioning that samples of the same analyte but prepared by alternative protocols may have significantly different metabolic compositions and could be classified into different "genera".
