Polissacarídeos da biodiversidade brasileira: uma oportunidade de transformar conhecimento em valor econômico

Abstract: Recebido em 21/1/09; aceito em 3/3/09; publicado na web em 17/3/09 POLYSACCHARIDES FROM BRAZILIAN BIODIVERSITY: AN OPPORTUNITY TO CHANGE KNOWLEDGE INTO ECONOMIC VALUE. A brief comment about general characteristics of polysaccharide was presented. Brazilian trade of polysaccharides was obtained from the "Ministério de Desenvolvimento, Indústria e Comércio Exterior" -Brazil. A list of these products was prepared and their price and amount analyzed in the period of 1998-2007. Some chemical properties and applicat… Show more

“…7 Brazil has approximately 680,000 ha planted with the cashew nut tree (Anacardium occidentale ) and the average production of gum/tree/year is 700 g, 8 with a potential annual cashew gum (CG) production of 50,000 tons. 9 The gum from Ceará State has been characterized as a heteropolysaccharide containing (by wt.%) the following neutral monosaccharides:galactose (72-73%), glucose (11-14%), arabinose (4.6-5.0%) and rhamnose (3.2-4.0%).…”

“…Essas características fazem aumentar sua expressão e dispersão pelos mais variados contextos, aumentando a importância do desenvolvimento de métodos analíticos, que permitam determinar, identificar e quantificar os açúcares presentes numa determinada matriz. 1 No que se refere à identificação e quantificação de compostos orgânicos, as técnicas cromatográficas gasosas hifenadas com a espectrometria de massas são ferramentas de eleição, mas, no caso particular da análise de glicídios, revelam-se pouco úteis. A análise desses compostos através dessas técnicas é dificultada porque, sendo os glicídios e os seus derivados compostos polihidroxilados, apresentam elevada polaridade, baixa volatilidade e ausência de grupos cromóforos.…”

“…Thus, the country suffers a commercial deficit in this field. 45 Over the last few decades, many reports have appeared on the composition and physiochemical properties of galactomannans from different plant sources. 6,33,[36][37][38][40][41][42][43][44][46][47][48][49][50][51][52][53][54][55][56][57][58][59] However, only guar, locust bean, tara and cassia gum are manufactured on a large scale, and these are being extensively investigated by various researchers.…”
