Aromatic and nutritional profile of an Amazonian autochthonous species, Caramuri Pouteria elegans (A.DC.) Baehni

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.
