| description | Vegetable tannins are found in several forest species. Actually, the Northeast Brazilian tanners have,
on Anadenanthera colubrina var. cebil, their only source of vegetable tannins. This study aimed to evaluate
the tanning capacity of tannins extracted from four vegetable species of Brazilian Semi-arid region, seeking
to make possible the diversification of species to be used in tannings in the region. Thus, physical and
mechanical characteristics of bovid treated skins with extract tannic of Anadenanthera colubrina var. cebil,
Anacardium occidentale, Mimosa tenuiflora and Mimosa arenosa were analyzed. The bovid skins were
tanned with extracted tannins of those species and compared to tanned skins by tannins of Acacia mearnsii
(Seta Natur commercial tannin). The samples of tanned skins were submitted to tension, lengthening and
progressive tear resistance tests. Good results were verified to tanned skins by Mimosa tenuiflora and
Mimosa arenosa. Due to the abundance of these species in Brazilian Semi-arid region, they showed potential
to exploration of tannins. However, researches are necessaries to indicate the best forms of application of
obtained tannins. |
