Abstract

The aim of this study was to characterize Caramuri Pouteria elegans (A.DC.) Baehni, an exotic fruit of the Amazonian biome to highlight it is a new source nutritional potential. The nutritional (vitamin A, B, C, and E) and volatile composition of the fruits was determined by physical [mass, diameter (longitudinal and transverse), yield] and chemical characterization (pH, acidity, soluble solids, proximate and mineral compositions) using headspace solid-phase microextraction (HS-SPME) by gas chromatography-mass spectrometry (GCMS). The amount of vitamin C, potassium, and magnesium detected per 100 g of sample was 143.08 mg, 97.50 mg, and 14.75 mg, respectively. Volatile profile by HS-SPME revealed 87 peaks, however, only 26 peaks were noted due to the small peak area (<1.0). Arithmetic and Kovats retention indexes were calculated for compound(s) identification. The percentage of volatiles identification was 88.46%. The majority compound was α-Pinene with 21.77%. The study reveals that Caramuri is a great source of vitamins and minerals, especially vitamin C.
