Composite design bioinspired by the mesocarp of Brazil nut (Bertholletia excelsa)

open access: yesBioinspiration & Biomimetics, 2022
Abstract The mesocarp of Bertholletia excelsa is a rich source of inspiration for strong, stiff and damage-tolerant composites. The bioinspired composites developed here are composed of an epoxy matrix with a 3D printed polylactic acid reinforced with 30% of carbon fiber (PLA-30CF) inspired in fibers, and syntactic foam inspired by ...

Aflatoxins in raw Brazil nut (Bertholletia excelsa H.B.K.)

open access: yesJournal of Agricultural Studies, 2023
The Brazil nut is a nutritionally rich food, produced and consumed in tropical regions. On the other hand, it may be suitable to toxigenic fungi and consequently contamination by aflatoxins (AFL), toxic substances to consumers. In this context, the objective of this work was to evaluate the occurrence of AFL in raw Brazil nuts, that is, before being ...
