摘要：The cajá fruit stands out for its peculiar flavor, but little is known about its physical, physical-chemical and nutritional characteristics. The knowledge of fruit and seed biometrics, physicochemical and nutritional composition provides information for the conservation and exploitation of resources of economic value, and can be exploited by genetic improvement programs to obtain cultivars that provide fruits with important characteristics for commercialization. Thus, it aimed to evaluate the characteristics we sought to evaluate these characteristics considering samples from different trees / regions of the municipality of Montes Claros of Goiás. The cajá fruit biometry (density, volume, mass, fruit and seed size and pulp yield) was measured. Titratable acidity, soluble solids content, pH, vitamin C content and mineral content were also measured. Total phenolic compounds and antioxidant activity were evaluated by the Folin-Ciocalteau, ORAC and ABTS methods, respectively. With the results obtained, it was possible to infer that the fruits harvested in different trees of different places differed statistically. The fruits of Region 2 had the highest fruit and seed length and diameter, as well as the highest pulp thickness, macro and micronutrient content and total phenolic compounds content, compared to fruit from other areas probably influenced by type of soil. The knowledge of the characteristics of the fruits from different trees / regions is necessary because the industrialization needs parameters for standardization in the formulation of different foods.↓O fruto cajá se destaca por seu sabor peculiar, mas pouco se sabe sobre suas características físicas, físico-químicas e nutricionais. O conhecimento da biometria dos frutos e sementes, composição físico-química e nutricional fornece informações para a conservação e exploração dos recursos de valor econômico, podendo ser exploradas por programas de melhoramento genético para obtenção de cultivares que propiciem frutos com características importantes para a comercialização. Assim, teve como objetivo avaliar as características considerando amostras de diferentes árvores/regiões do município Montes Claros de Goiás. Foi mensurado a biometria do fruto cajá (densidade, volume, massa, dimensões dos frutos e sementes e o rendimento da polpa). Também foi mensurado a acidez titulável, teor de sólidos solúveis, pH, conteúdo de vitamina C e o conteúdo mineral. Os compostos fenólicos totais e a atividade antioxidante foram avaliados pelos métodos Folin-Ciocalteau, ORAC e ABTS, respectivamente. Com os resultados obtidos, foi possível inferir que os frutos colhidos em diferentes arvores de diferentes locais diferiram estatisticamente. Os frutos da região 2 tiveram o maior comprimento e diâmetro da fruta e da semente, bem como a maior espessura da polpa, o conteúdo de macro e micronutrientes e o conteúdo de compostos fenólicos totais, em comparação com os frutos de outras áreas provavelmente influenciado pelo tipo de solo. O conhecimento das características dos frutos oriundos de diferentes arvores/regiões é necessário pois a industrialização precisa de parâmetros para padronização na formulação de diferentes alimentos.
