Resumo
The objective of this work was to develop a recommendation for the chemical peeling of pequi fruit and characterize the flour obtained
from the external mesocarp of “Pequizeiro”, pequi tree (Caryocar brasiliense Camb.). The technology applied to obtain the external mesocarp
pequi flour included the epicarp removal with NaOH solution. The Response Surface Method was used to optimize the chemical peeling
process by applying the Central Composite Rotatable Design, with eleven trials including three replicates at the central point, varying the
NaOH aqueous solution concentration and fruit immersion time. The mass loss was evaluated through the analysis of variance and using
bi and three dimensional graphs. The chemical characteristics of the external mesocarp pequi flour evaluated were: moisture content, ashes,
proteins, lipids, total carbohydrates, dietary fiber, and some minerals. The best combination for an efficient removal of the fruit peel with the
lowest mass loss was reached with 7.05 minutes of immersion in a 5.08 g.L-1 NaOH aqueous solution. This study indicated that the external
mesocarp pequi flour is a food source rich in dietary fiber, carbohydrates, ashes, magnesium, calcium, manganese, and copper, but it is poor
in lipids, zinc, and iron.
