Abstract Syagrus coronata known as licuri, ouricuri, or uricuri is a palm tree from dried areas in Brazil and it is an important resource for the local population. The objective of this work was to evaluate the nutritional value of licuri kernels from the Territory of Sisal (State of Bahia) and to develop cookies prepared with licuri kernels and cassava flour. The licuri kernel showed high content of total dietary fiber (13 -15%) with values equivalent to that observed for coconut kernel. The content of minerals such as zinc, magnesium, phosphorus, manganese, iron, and copper was similar to those recorded for commercial nuts and superior to coconut kernel. The licuri kernel presented an oil content of 61-66%, with a predominance of lauric acid. The main sterols were Sitosterol, Campesterol and Δ5-avenasterol. The formulations of cookies with licuri kernel (5 and 10%) and commercial cassava flour (4.5 and 9%) showed no differences in general acceptance, aroma, flavor, and texture. The kernel of Syagrus coronata represents an important source of dietary fiber, lipids, and minerals and the results indicate that besides its traditional application, this use represents the increasing the nutritional value of cookies in compliance with global trends.

RESUMO O uso de lenha e carvão vegetal produzido a partir de plantios florestais tem apresentado tendências de crescimento na matriz energética brasileira. Essas fontes de energia renováveis têm sido foco de estudos e políticas públicas, visando à reestruturação das cadeias produtivas para o suprimento da demanda. O objetivo desse trabalho foi analisar a dinâmica mercadológica da lenha e carvão vegetal da silvicultura no Brasil, considerando a evolução da produção e dos preços, a concentração da produção e sua localização geográfica nos municípios e estados brasileiros. Utilizou-se como base de dados, a produção e o valor da produção municipal, obtidos junto ao Instituto Brasileiro de Geografia e Estatística (IBGE) e da Pesquisa da Extração Vegetal e Silvicultura (PEVS), considerando o período entre os anos 2001 e 2011. A taxa de crescimento da produção, a curva de Lorenz, o índice de Gini e a distribuição espacial em mapas da produção de lenha e carvão vegetal no Brasil foram as ferramentas de análise utilizadas. Os principais resultados evidenciam uma concentração da produção de lenha nos três estados do Sul do Brasil e do carvão vegetal em Minas Gerais. O aumento dos preços indica que a demanda não está sendo suficientemente suprida, sobretudo nos estados em que a produção ainda é insipiente.

ABSTRACT The use of firewood and charcoal produced from forest plantations has presented growth trends in the Brazilian energy matrix. These renewable energy sources have been the focus of studies and public policies aimed at restructuring of production chains for the supply of demand. The aim of this study was to analyze market dynamics of firewood and charcoal of forestry in Brazil, considering the evolution of production and prices, the concentration of production and its geographical location in the municipalities and in Brazilian states. It was used as a base data, production and value of the production hall, obtained by the Brazilian Institute of geography and Statistics (IBGE) and the Extraction Vegetal and Forestry Research (PEVS), considering the period between 2001 and 2011. The growth rate of production, Lorenz Curve, Gini index and the spatial distribution maps of production of firewood and charcoal in Brazil were the analysis tools used. The main results show a concentration of the production of firewood in the three states of southern Brazil and charcoal in Minas Gerais state. The rise in prices indicates that the demand is not being sufficiently supplied, especially in the states where the production is still incipient.
