QUALITY, BIOACTIVE COMPOUND CONTENT, AND ANTIOXIDANT ACTIVITY IN FRUITS OF BRAZILIAN ACEROLA CLONES

Acerola is a fruit with a high nutritional value, not only due to its vitamin C content, but also to -carotene and anthocyanins.
The aim of this work was to evaluate the quality and the total antioxidant activity in fruits of six commercial acerola clones.
Fruits were analyzed for total soluble solids (TSS), soluble sugars, total titrable acidity (TTA), pH, vitamin C, anthocyanins, yellow flavonoids, total carotenoids, total extractable polyphenols and total antioxidant activity by the DPPH, ABTS and FRAP methods.
The ‘II 47/1’ clone had the highest vitamin C and anthocyanin contents among all the clones tested.
Acerola fruits, evaluated by the DPPH method, had an average EC₅₀ of 697.1, with the clone II 47/1 having the highest value (461.5 g/g pulp). For the ABTS method, fruits from ‘Cereja’ and ‘II47/1’ had the highest values with 158.7 and 138.3 μM Trolox/g pulp, respectively.
There was a significant difference among samples.
For the FRAP method, the clone ‘Sertaneja’ showed the highest value of 306.9 μM Fe₂SO₄/g pulp.
