Abstract: This work presents a methodology for the extraction of galactomannans from seeds of four different species of Leguminosae (Adenanthera pavonina, Caesalpinia pulcherrima, Gleditsia triacanthos and Sophora japonica) to be used e.g. in the food and biomedical industries. The galactomannans were obtained by aqueous extraction followed by a precipitation with ethanol. This methodology is simpler and easier to perform than other existing extraction and purification methodologies, and because it avoids the use of org… Show more

“…FAO (1995) reported yield values for tara of 38-40%, 22-27% and 26-40% for these fractions. The yield obtained in honey locust was similar to that obtained by Cerqueira et al (2009) in gum extracted with ethanol, and somewhat superior to that reported by Sciarini et al (2009) for purified gum.…”

“…In algarrobo, tara, honey locust and other species different mechanical, physical and chemical methods have been studied for the removal of the seed coat and for separating the coat, the endosperm (gum) and the cotyledons (Wielinga, 2000;Cerqueira et al, 2009). Chemical extraction methods studied include sodium hydroxide 0.75% w/v and 72% w/v sulfuric acid with different temperatures and contact times (Escobar et al, 1987;Vásquez et al, 1988, Cruz, 1999Estévez et al, 2004;Vega, 2006 andMartínez, 2007).…”

“…Its seeds are popularly known as "carolina" or dragon eye and draw attention due to their bright red color. Galactomannans extracted from the A. pavonina seed endosperm has attractive properties for applications in the food and biomedical industries [4]. The A. pavonina plant, its seeds, and the biopolymer extracted from the same can be seen in Figure 1.…”

“…In Latin America, the number of known sources of galactomannans is small, despite the rich biodiversity of the local flora and the favorable climate for their production. [31][32][33][34][35][36][37][38][39][40][41][42][43][44] In 2008, Brazil imported approximately US$ 142,000 of total polysaccharides but exported only U$ 68,000. Guar imports represented US$ 18,000 over the five-year period of 1993-2007 and around 10,000 tons, at a price of U$ 1.9/kg.…”

“…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. 5,11,12,19,21,[60][61][62][63][64][65][66] Srivastava and Kapoor 6 described, in their overview of galactomannans, chemical screening of more than 300 Indian species of water-soluble gums.…”
