Abstract

The objective of this study was to determine the proximal composition, the physical and chemical characteristics and the in vitro antioxidant capacity (DPPH, ABTS and FRAP) of the pulp of the wild passion fruit ( Passiflora glandulosa Cav.) from Cariri region, Ceara, Brazil. The results showed that the proximal composition and the caloric value of this passion fruit are similar to other species, but with a high ascorbic acid content. The fruit pulp showed low level of antioxidant activity and low level of polyphenolic compounds followed by three methodologies used. Due to high levels of titratable acidity (3.52) and total soluble solids (17.80° Brix), this fruit can be considered as a high value fruit for commerce. However, it is a species of passion fruit with few studies described in the literature, and more research is needed to assess its nutritional and functional potential.

Highlights

Tropical countries produce a large number of edible fruits, and Brazil has suitable climatic conditions for growing many fruit species, native and exotic, that are of potential interest to the agricultural industry and possible sources of income for the local population (Rosso, 2013)
The chemical composition of wild passion fruit pulp is described in Table 1 and it was compared with the average values found in the literature for the species Passiflora alata and Passiflora edulis f. flavicarpa
The average content in the wild fruit observed for dietary fiber was 2.03%, and its ash content was 0.72%

Summary

Introduction

Tropical countries produce a large number of edible fruits, and Brazil has suitable climatic conditions for growing many fruit species, native and exotic, that are of potential interest to the agricultural industry and possible sources of income for the local population (Rosso, 2013). Worldwide fruit consumption has increased due to its nutritional potential and effects on health promotion (Vasco, Ruales, & Kamal-Eldin, 2008) In addition to their refreshing flavors and delicious aroma, fruits are sources of antioxidants, such as phenolic compounds, vitamins, carotenoids and minerals, which contribute chemo-preventive effects on human health (Vasco et al, 2008). The fruits are globose, 4-5 cm in diameter, with an average weight of 22 g, yellow-orange when ripe and with white pulp. It is much appreciated by the locals, being consumed as a fresh fruit or as a juice. P. glandulosa Cav. is not cultivated, and the fruits are collected directly from forest during the fruiting period, hindering access to and knowledge of the fruit by the majority of the population (Figure 1)
