Linking geographical origin with nutritional, mineral, and visual proprieties of pinhão (Araucaria angustifolia seed) from the south of Brazil.

The effect of harvest location on cooked pinhão seeds (Araucaria angustifolia) was investigated with regard to its centesimal composition, minerals, and color, and later correlated with environmental and soil variables. Significant differences between cooked pinhão from various harvesting locations were seen; also, principal component analysis was performed for the minerals, protein, moisture, total starch, and color parameters. The geographic location was one of the most important factors.
