Introduction. The mangaba is
an exotic fruit from the Brazilian Cerrado that presents high antioxidant
activity and may benefit human health. Its antioxidant activity
may be associated with the presence of bioactive compounds such
as carotenoids and antioxidant vitamins. The physical and chemical
characteristics, nutritional value, carotenoids and antioxidant
vitamins were evaluated in mangaba from the Cerrado of Minas Gerais,
Brazil. Materials and methods. Titratable acidity was
determined by volumetric neutralization, pH by potentiometry, soluble
solids by refractometry, moisture by gravimetry after oven drying,
ash by calcination in a muffle furnace, proteins by the micro-Kjeldhal
method, dietary fibers by the gravimetric non-enzymatic method and
lipids by gravimetry after extraction in ethyl ether. Vitamin C
(ascorbic and dehydroascorbic acids) and carotenoids (α-carotene,
β-carotene, β-cryptoxanthin and lycopene) were analyzed by HPLC-DAD.
Vitamin E (α-, β-, γ- and δ-tocopherols and tocotrienols) and folates
(tetrahydrofolate, 5-methyltetrahydrofolate and 5-formyltetrahydrofolate)
were analyzed by HPLC with fluorescence detection. Results
and discussion. Mangaba showed a high pulp yield (80.08%), moisture (83.0 mg×100 g–1) and
dietary fiber content (2.3 g×100 g–1). Mangaba presented β-carotene,
β-cryptoxanthin, ascorbic acid, α-tocopherol; α-, β- and γ-tocotrienols; tetrahydrofolate,
5-methyltetrahydrofolate and 5-formyltetrahydrofolate, and it can be
considered an excellent source of vitamin C (165.8 mg×100 g–1) and
folates (98.3 μg×100 g–1). Carotenoid and vitamin E contents were 0.12 mg×100 g–1
and 2,732.5 μg×100 g–1, respectively. Conclusion. Mangaba
presented a high pulp yield, and several carotenoids and antioxidant vitamins,
and can be considered an excellent source of vitamin C and folates.
