Physicochemical characterization, extraction and analysis of pectins from fruit of Campomanesia Xanthocarpa B. (Gabiroba)

Abstract

Campomanesia xanthocarpa Berg. (Myrtaceae) is a Brazilian native tree, with large range of wild natural distribution or as dooryard tree, in the de South Region. It presents enlarge fructification and grows in poor soils at hot or dry climates. The mature fruit is green-yellow, and the pulp is sweet and richest in vitamins, and are used to make juices or eaten fresh. The fruit contains macro and micronutrients: proteins (1.08 g/100 g), fats (0.12 g/100 g), reduces sugar (8.3 g/100 g, being fructose 4.0 g/100g; glucose 4.3 g/100g), mineral salts (iron 3.52, calcium 28.45, phosphorus 25.3 mg/100g, potassium 1.53mg/100g). The high contents of phenolic compounds (1616 ppm/100g) and vitamin C (233.56 mg/100g) is remarkable indicating this fruit as functional food. The succulent pulp and fruit characteristic flavor can be taken as advantage in the preparation of frozen pulp and an excellence raw material to preparation of juices, jellies, ice creams etc. The fruit texture can be attributed to pectin contents that was extracted and analyzed. This fruit has technological potential due to sensorial and nutritious properties.
