Investigation of Southern Thailand Sweet Pickled Mango Metabolic Profiles Related to Deterioration

Congratulations to Dr. Niken Indrati and Assoc. Prof. Dr. Sakda Khoomrung of the Siriraj Center of Research Excellence in Metabolomics and Systems Biology (SiCORE-MSB), Faculty of Medicine Siriraj Hospital, Mahidol University, for their latest research publication in Food Chemistry on March 1, 2025.

Their study, “Investigation of Southern Thailand Sweet Pickled Mango Metabolic Profiles Related to Deterioration”, aimed to elucidate key metabolites linked to the deterioration of mango-based condiments (MBC) stored at 4°C (STR4) and 30°C (STR30). The results indicate that deterioration is associated with increased levels of ethyl acetate, isopropyl alcohol, trans-β-ocimene, isopentyl acetate, 2-phenethyl acetate, glucose, and fructose, alongside a decrease in sucrose. Notably, isopentyl acetate, ethyl acetate, and 2-phenethyl acetate were significantly higher in STR4 than in STR30, with log2[fold change (FC)] values of 3.2, 2.0, and 1.0, respectively. In contrast, sucrose levels in STR4 were lower than in STR30 (log[FC] -1.4), suggesting a longer storage-induced sucrose hydrolysis in STR4. Given the abundance of volatile metabolites in deteriorated MBC, the study proposes that applying odor- or flavor-absorbing films in MBC packaging could help prolong shelf life.
