Previous issue date: 2014-07-31 / O feij?o caupi (Vigna Unguiculata L. Walp) ? uma das principais culturas
alimentares do nordeste brasileiro. No Rio Grande do Norte, o feij?o caupi, feij?o vigna ou
feij?o macassar, como ? conhecido, tem grande import?ncia socioecon?mica como fonte
de nutrientes na alimenta??o humana, com grande destaque entre os produtos agr?colas.
Para melhorar a produtividade e resist?ncia contra pragas, duas cultivares foram
desenvolvidas, exclusivamente pela EMPARN (Empresa de Pesquisa Agropecu?ria do Rio
Grande do Norte), por melhoramento gen?tico. As amostras foram fornecidas pela
EMPARN, sendo duas melhoradas (Potiguar e Riso do ano) e duas crioulas (Costela de
vaca e Canapu). As sementes foram trituradas e transformadas em farinhas e com as
amostras foram realizadas as determina??es de umidade e cinzas por m?todos
gravim?ticos, lip?deos por extra??o com Soxhlet, fibras com determinador de fibras,
carboidratos por diferen?a e minerais por ICP-OES, exceto o f?sforo analisado por UVvis.
Os resultados mostraram um alto conte?do de fibras (55,55% e 55,32% amostras
melhoradas e 50,04% e 50,32% amostras crioulas) e prote?nas (25,52% e 25,27% amostras
melhoradas e 27,23% e 24,99% amostras crioulas). Comparando os resultados dos teores
de minerais, as cultivares melhoradas se destacaram em rela??o a Ca, Co, P, Mg, Mo e Na.
As cultivares crioulas apresentaram melhores resultados de Cu, Cr (baixo teor), Fe, Mn,
Ni, K e Zn. Os resultados obtidos ser?o importantes em futuras pesquisas nutricionais e
para constru??o de uma tabela brasileira de composi??o qu?mica de alimentos. / The cowpea (Vigna unguiculata L. Walp) is a major food crops in northeastern Brazil. In
Rio Grande do Norte, the cowpea, vigna beans or cowpea, as it is known, has great socioeconomic
importance as a source of nutrients in food, with great emphasis among
agricultural products. To improve productivity and resistance to pests, two cultivars were
developed exclusively by EMPARN (Agricultural Research Corporation of Rio Grande do
Norte), for breeding. The samples were provided by EMPARN, two improved (Potiguar
and Laugh year) and two landraces (Rib of beef and Canapu). The seeds were ground and
made into flour samples and the determination of moisture and ash by gravim?ticos
methods, lipids by Soxhlet extraction, fibers with determiner fiber, carbohydrates by
difference and minerals by ICP-OES were performed except the match analyzed by UVvis.
The results showed a high fiber content (55.55% and 55.32% and 50.04% improved
samples and 50.32% creole samples) and protein (25.52% and 25.27% improved and 27
samples, 23% and 24.99% creole samples). Comparing the results of the mineral content,
the improved cultivars stood out in relation to Ca, Co, P, Mg, Mo and Na. Creole cultivars
showed better results for Cu, Cr (low), Fe, Mn, Ni, K and Zn. The results will be important
in future nutritional research and to build a table of Brazilian chemical composition of
foods.
