Five selected fruits in Batangas namely banana (Musa lacatan), chico (Manilkarasapota),
papaya (Carica papaya L.), pomelo (Citrus grandis) and tamarind (Tamarindicusindica) were analyzed
for their proximate analysis, antioxidant properties and antioxidant activity. The study aimed to make a
baseline database using the information obtained which will be useful for further studies and
improvement of existing products and food processes and for development of new ones. Among the five
selected fruits, tamarind got the highest ash content of 12.51%, crude protein of 4.68%, crude fat of
3.39% and total carbohydrates of 46.67% but the lowest moisture content of 33.45%. Pomelo got the
highest moisture content of 91.74% while chico got the highest crude fiber content of 2.64%. Papaya had
the lowest total carbohydrates of 7.54% while banana had the lowest crude fiber content of 0.51%. For
the antioxidant properties, tamarind had the highest TFC of 0.007 mg quercetin / L, TPC of 0.223 mg
gallic acid / L, and Vitamin C of 1024.41 mg/100cm³ while papaya had the highest Beta-carotene content
of 286μg/100g. The selected fruits exerted remarkable antioxidant properties. Pomelowith 94.4% hadthe
strongest antioxidant activity followed by chico with 91.96%, then banana with 90.84%, papaya with
88.72% and lastly by tamarind with only 70.69%. Based on the statistical treatment of results, there were
significant differences in the antioxidant properties and antioxidant activity of selected fruits in Batangas.
