Abstract/Summary

Among the main fruit crops in the Philippines, mangoes (Mangifera) are comparatively understudied when it comes to their physicochemical characteristics, metal content, and volatile compounds. Recent studies have mostly concentrated on mango illnesses causing a gap in what we know about the content of these fruits. This research addresses this gap by investigating the physicochemical attributes, metal content, tannin content, and volatile compounds of seven mango varieties: Carabao mango, which includes subvarieties Guimaras Super and Sweet Elena, Red mango including subvariety Keitt, Paho, Indian, Golden Queen, Kinabayo, and Millennium mangoes, sourced from diverse regions across the country. Comparative analyses of physicochemical properties, including titratable acidity and moisture content, were conducted to discern variations among the different mango varieties. Atomic absorption spectroscopy (AAS) was employed to determine the metal content in each mango variety. Furthermore, gas chromatography-mass spectroscopic (GC-MS) analysis was utilized to identify and compare the profiles of volatile compounds present in each mango variety. The outcomes of this study contribute valuable scientific insights into Philippine mangoes, particularly their physicochemical composition, tannin and metal content, as well as volatile compound profiles, offering practical implications for post-harvest processing and enhancing the overall understanding of this vital fruit crop.
