Use of metabolomics data analysis to identify fruit quality markers enhanced by the application of an aminopolysaccharide.

ABSTRACT: Chitosan is a biostimulator that has a great effect either on plant physiology, productivity, or fruit quality. However, the metabolic mechanism regulated by chitosan still remains unknown. Untargeted metabolomics analysis, using LC-MS/MS mass spectrometry, was used to investigate fruit quality markers. Thus, this study was focused on the identification of untargeted metabolites of tomato fruits produced under the application of five doses of chitosan at different concentrations (0, 0.25, 0.50, 0.75, and 1 mg ml^-1) that was extracted from Parapenaeus longirostris shrimp shells. The identification was carried out using two ion modes (ESI^-/ESI⁺), a web application "Metfamily" to analyze signals, and reference libraries. The analysis of data using parti
