Metabolic profiles alteration of Southern Thailand traditional sweet pickled mango during the production process

Abstract

Sweet pickled mango named Ma-Muang Bao Chae-Im (MBC), a delicacy from the Southern part of Thailand, has a unique aroma and taste. The employed immersion processes (brining 1, brining 2, and immersion in a hypertonic sugar solution, sequentially) in the MBC production process bring changes to the unripe mango, which indicate the occurrence of metabolic profiles alteration during the production process. This occurrence was never been explored. Thus, this study investigated metabolic profile alteration during the MBC production process. The untargeted metabolomics profiling method was used to reveal the changes in volatile and non-volatile metabolites. Headspace solid-phase micro-extraction tandem with gas chromatography quadrupole time of flight (GC/QTOF) was employed for the volatile analysis, while metabolites derivatization for non-volatile analysis. In conclusion, a total of 82 volatile and 41 non-volatile metabolites were identified during the production process. Terpenes, terpenoids, several non-volatile organic acids, and sugars were the major mango metabolites that presented throughout the process. Gamma-aminobutyric acid (GABA) was only observed during the brining processes, which suggested the microorganism’s stress response mechanism to an acidic environment and high chloride ions in brine. Esters and alcohols were abundant during the last immersion process, which had an important role in MBC flavor characteristics. The knowledge of metabolites development during the MBC production process would be beneficial for product development and optimization.

Anti‐Cancer Activity of Ethanolic Extract from ‘Bao’ Mango (Mangifera indica) Peel and Its Nanoencapsulation Against Triple‐Negative Breast Cancer Cell Lines

“…It can be used as a substitute for lime and lemon in cooking. [1] While anecdotal evidence suggests potential health benefits, there was no scientific investigation on the properties of this 'Bao' mango. Notably, various components of different mango varieties such as 'Nam Dok Mai' including the bark, kernel, leaves, peel, and pulp have been extensively studied for their potential anticancer, anti-inflammatory, antimicrobial, antioxidant, and immunomodulatory properties in vitro and in vivo.…”
