| Titratable acidity (%) | 0.65 ± 0.03b | 0.87 ± 0.03a |
| pH | 4.12 ± 0.01b | 4.83 ± 0.03a |
| Phenolic extract | ||
| Content of total phenolic compounds (mg GAE/g of pulp or seed) | 1.56 ± 0.01b | 22.59 ± 0.79a |
| Antioxidant activity (EC50 g of fresh sample/g of DPPH) | 5301.95 ± 96.28a | 211.75 ± 10.99b |
M ± SD, Means ± standard deviation, Means followed by different superscript letters in the same line differ among themselves at 5% probability (p ¡ 0.05) by Tukey’s test. n.d., not determined; GAE, gallic acid equivalent; EC50, corresponds to the sample concentration required to reduce the initial DPPH radical concentration by 50%. DPPH – (2,2-diphenyl-1-picrylhydrazyl).
