EVALUATION OF THE USE OF ETHYLENE INHIBITORS ON PRODUCTION OF VOLATILE COMPOUNDS AND MANGIFERIN IN MANGO FRUIT

摘要

EVALUATION OF THE USE OF ETHYLENE INHIBITORS ON PRODUCTION OF VOLATILE COMPOUNDS AND MANGIFERIN IN MANGO FRUIT. Effects of two ethylene inhibitors, 1-methylcylopropene (1-MCP) and aminoethoxyvinylglycine (AVG), on production of volatile compounds and mangiferin (a bioactive xanthone) in 'Tommy Atkins' mango fruit were investigated. Volatile composition and mangiferin content, in treated and untreated fruits at three maturity, stages were determined by SPME-GC-MS and HPLC, respectively. These chromatographical analysis revealed that the volatile profiles and mangiferin concentrations were not significantly different, suggesting that the use of ethylene inhibitors does not affect the mango aroma and functional properties relative to this xanthone. Moreover, a simple, precise and accurate HPLC method was developed for quantifying mangiferin in mango pulp.
