Although the consumption of Amazonian fruits has a regional predominance, these fruits present great possibilities for their use in agroindustry. Also, scientifc research that seeks to identify functional properties in fruits also promotes their commercial value and, as a consequence, can beneft family farming and contribute to the sustainable development of the region. Te most signifcant challenge for the exploration and commercialization of new fruit species, particularly in the most distant and hard-to-reach areas is the preservation of their organoleptic characteristics and their nutritional value, given the prospect of high perishability during transport [13]. Nowadays, the post-harvest loss of fruit in Brazil reaches 30%. Tese losses stem from the choice of inappropriate cultivars, improper postharvest techniques, poor transport conditions and inadequate storage for the products. On the other hand, there is a growing interest in processed fruits, both domestically and abroad the country, due to the demand for healthy foods that are convenient and ready for Nutritional composition of the pulp of Pajurá (Couepia bracteosa Benth.), an underutilized fruit from the Amazon Lais Tatiele Massing 1 , Rosa Helena V Mourão 1,2 , Leoneide Érica M Bouillet 2 , Regiane Sablina A Bernardes 2 , Eloisa Helena A Andrade 3 , Agnaldo Tremea 4 , Jesus Nazareno S Souza 5 and José Guilherme S Maia 3 * 1 Programa de Pós-Graduação em Biociências, Universidade Federal do Oeste do Pará, 68035-110 Santarém, PA, Brazil 2 Laboratório de Bioprospecção e Biologia Experimental, Universidade Federal do Oeste do Pará, 68035-110 Santarém, PA, Brazil 3 Programa de Pós-Graduação em Química, Universidade Federal do Pará, 66075-900 Belém, PA, Brazil 4 Instituto Nacional de Colonização e Reforma Agrária, 68040-060 Santarém, PA, Brasil 5 Faculdade de Engenharia de Alimentos, Universidade Federal do Pará, 66095-780 Belém, PA, Brasil Abstract Couepia bracteosa Benth. (Chrysobalanaceae), known as pajurá, is a native fruit that occurs spontaneously in the Amazon region, with an exotic favor and low commercial exploitation. Tis study describes the biochemical and nutritional composition and the antioxidant and hemagglutinating activities for the natural and lyophilized Pajurá pulps. Fruits are characterized by their high percentage of sugar and total fber content (34.7%), signifcant antioxidant capacity (DPPH, 53.42%; β-carotene/linoleic acid, 69.85%) and the absence of haemagglutinating activity. Te percentile of vitamin C (22.42 mg/100 g), total phenolic compounds (124.53 mgGAE/100 g) and total carotenoids (2898.76 μg/100 g) were also evaluated. Primary fatty acids found in its lipid fraction were oleic (30.2%), lauric (18.1%), palmitic (16.1%), and myristic (11.1%) acids. Also, the pulp presented a pleasant aroma with a high content of (E)-β-Ocimene (49.2%). It is presumed that results can contribute to a better fruit utilization, which may have potential application as a novel functional food. Introduction In addition to their organoleptic characteristics, many fruits have attracted the attention of the scientifc research and consumers due to the presence of minerals, vitamins, bioactive compounds, and fbers. Fruits with these properties can contribute to the risk reduction of chronic non-communicable diseases, such as cancer and cardiovascular diseases [1,2]. In Brazil, it is estimated that 44% of the native fruits are located in the Amazon region, considered a valuable natural reserve of food and medicinal plants worldwide. However, most of the native fruits from the Amazon are wild or cultivated only for the local markets, not having yet defned their economic potential. Tis fact is due to the absence of studies related to the conditions of crop growth, lack of data on the composition of the fruits, their nutritional value, lack of knowledge about the presence of bioactive compounds and the possibilities of commercialization [2,3]. Couepia bracteosa Benth. (Chrysobalanaceae), popularly known as Pajurá, is a fruitful species of the Brazilian Amazon, occurring in the Pará, Amazonas, and Roraima states. Te tree is between 12 to 25 meters long, produces globular fruit type drupe of brown epicarp and yellowish pulp, thick and granular, with a pleasant aroma and sweet taste. Te harvest occurs between November and May, and the fruit is consumed regionally in nature or as an ingredient in desserts [4]. Previously, the proximate composition, fatty acid and mineral content, and identifcation of some phenolic and carotenoid compounds were analyzed and determined in the pulp of C. bracteosa [5-7]. Also, there are records of bioactive compounds identifed in other Couepia species, such as the conjugated fatty acids in the seed oils of C. edulis Correspondence to: José Guilherme S.
