INTRODUCTION
A. Background of the Study The energy value per 100 g (3.5 oz) is 250 kJ (60 kcal), and that of the apple mango is slightly higher (79 kcal per 100g). Mango contains a variety of phytochemicals and nutrients. Mango peel and pulp contain other compounds, such as pigment carotenoids and polyphenols, and omega-3 and -6 polyunsaturated fatty acids. Although not confirmed scientifically, mango peel pigments may have biological effects, including carotenoids, such as the provitamin A compound, beta-carotene, lutein and alpha-carotene, polyphenols such as quercetin, kaempferol, gallic acid, caffeic acid, catechins, tannins, and the unique mango xanthonoid, mangiferin, which are under preliminary research for their potential to counteract various disease processes. Phytochemical and nutrient content appears to vary across mango cultivars. Up to 25 different carotenoids have been isolated from mango pulp, the densest of which was beta-carotene, which accounts for the yellow-orange pigmentation of most mango cultivars. Peel and leaves also have significant polyphenol content, including xanthonoids, mangiferin and gallic acid.
The mango is a juicy stone fruit belonging to the genus Mangifera, consisting of numerous tropical fruiting trees that are cultivated mostly for edible fruit. The majority of these species are found in nature as wild mangoes. They all belong to the flowering plant family Anacardiaceae. The mango is native to South and Southeast Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. The highest concentration of Mangifera genus is situated in western part of Malesia (Sumatra, Java and Borneo) and in Burma and India. While other Mangifera species (e.g. horse mango, M. foetida) are also grown on a more localized basis, Mangifera indica – the 'common mango' or 'Indian mango' – is the only mango tree commonly cultivated in many tropical and subtropical regions.
