CARACTERIZACAO FISICO QUIMICA DE GABIROBA (Campomanesia lineatifolia) E MURTA (Blepharocalyx salicifolius) NATIVAS DA REGIAO SERRANA DE IBIAPABA CE
In Brazil, consumer preference of tropical native fruits has increased; however, many fruits are not commercially exploited, such as gabiroba (Campomanesia lineatifolia) and myrtle (Blepharocalyx salicifolius) from the Myrtaceae family. The present study aimed to evaluate the physical, physico chemical, and functional characteristics of gabiroba and myrtle, harvested from native plants in the mountainous region of Ibiapaba CE. The following characters were analyzed: pH, soluble solids, total acidity, total extractable polyphenols, ascorbic acid, and antioxidant activity by using the ABTS method. After pulping, the samples were divided into two groups. From the results, it was found that gabiroba had a low total acidity value (0.12 0.01% indicating a higher level of sweetness relative to myrtle. Myrtle presented values of longitudinal (0.94 cm) and transverse(1.35 cm) diameters, fresh weight (0.85g) pulp yield (68.0% pH (4.5 0.0) and total soluble solids (23.6 1.7 degBx) similar to those obtained in other studies. Bioactive compounds in gabiroba and myrtle included phenolics (GAE 229.37 1.04and 511.65 1.34mg/100g) ascorbic acid (74.44 0.03 369.1 0.28 mg/100g) and antioxidants (14.54 1.0 and 16.05 0.63 m Mtrolox/g) Therefore, these fruits have the potential to be used as functional foods characterized by various health benefits.
