Summary: This study aimed to perform the characterization of raw pine nuts from Curitiba and Guarapuava, cities of Paraná State. The pine nuts showed peculiar characteristics, being influenced by genetic inheritance and or environmental conditions of different cities. The main differences found between samples were in relation to starch content 45,16 ± 1,38 and 57,26 ± 3,15 (g/100g); average mass of seeds 5,35 ± 0,79 and 7,91 ± 0,57(g); and external hardness of almond 13,87 ± 0,57 and 24,11 ± 3,49, respectively for samples from Curitiba and Guarapuava. The pine nuts show as a good source of starch, with pH near to neutrality and a high activity of water so these factors may compromise your stability. Therefore, the regions of sample collection influence the characteristics of pine nuts.
