Mass spectrometry-based metabolomics study for delay tomato fruit ripening by sound waves

Abstract Tomato ( Solanum lycopersicum L.) is one of the most consumed vegetables worldwide. The ripening tomato performed for its freshness and represented by color gene expression. In our previous study, we molecular analyses on with without sound-wave treatment. present metabolomics analysis tomatoes treatment to expand knowledge ripening. To achieve this goal, at 7, 10, 14 d were selected analyzed via liquid chromatography–mass spectrometry (LC–MS) gas chromatography–MS (GC–MS). A total 33 major metabolites, including LC–MS- 19 GC–MS-derived assigned based variable importance projection p values subjected statistical analysis. Apparent morphology partial least squares–discriminant consistent general process color. Moreover, showed similar experimental results those studies. quantification metabolites LC–MS decreasing levels adenosine, tryptophan, phytosphingosine upon GC–MS analysis, 4-Aminobutanoic acid aspartic decreased On other way, quantity malic acid, citric sucrose was increased findings study can assist in application delaying improving their market value.
