Interpretive Summary: Mango (Mangifera indica L.) is one of the most important tropical fruits, grown commercially in more than 87 countries. Mango currently ranks fifth in total production among major fruit crops worldwide. The world production of mango was 50,650,000 metric tons in 2017. The fruit possesses attractive aroma, delicious taste, and high nutritional value, due to its high levels of vitamin C, beta-carotene and minerals. This study examined the physicochemical properties and antioxidant composition of four mango varieties (Tommy Atkins, Apple, Keitt, and Kent) grown in Ethiopia. This study confirmed that mangoes are a good source of vitamin C, carotenoids, and minerals and that their composition is similar to mangoes grown in other countries.
Technical Abstract: The objectives of this study were to determine the phytochemical properties and antioxidant composition of four mango varieties (Tommy Atkins, Apple, Keitt, and Kent) grown in Ethiopia and to compare their composition to previously reported results on mangoes grown in other parts of the world. The Keitt variety had the highest fruit weight, fruit length, fruit diameter, and juice volume content. The pH, TSS, TA, and TSS/TA and proximate composition (moisture, ash, fat, fiber, and protein) showed significant differences among the varieties at p = 0.05. Minerals such as Na, Mg, K, Ca, Fe and Zn were also evaluated and potassium had the highest concentration among the minerals with the grand mean of 267.445 mg/100 g. Varieties also differed in antioxidant content such as total carotenoids and vitamin C with values ranging from 0.6 to 4.8 µg/g and 14.2 to 36.4 mg/100 g respectively. Apple, Kent and Keitt mango varieties are good sources of vitamin C. The four mango varieties had similar physicochemical properties and antioxidant content compared to mangoes grown in other countries.
