However, for the cashew crop becomes a more profitable and sustainable activity, being necessary to take full advantage of the cashew co-products such as the cashew gum (resin), since it is cultivated in a large area and due to the similar aspect with Arabic gum.
Polysaccharides such as Arabic gum, cashew gum and others can still move numerous research papers, involving studies of extraction, identification and characterization processes, properties, biological activities and applications (Yang & Zhang, 2009).
Despite the fact that dwarf cashew is a semi-arid climate crop, with little water requirement, the use of irrigation allows the improvement in the cashew nut and peduncle production (Lima et al., 2010) and, perhaps, this water application can influence the production of cashew gum. Another important factor for improving productivity is soil fertility, that can define the conditions for the mineral nutrients supply, which, under appropriate conditions, provides higher yield and quality(Melem Junior et al., 2008).
(2001), evaluating chemical stimulants on the cashew gum extraction, observed higher gum exudation rates in the month of September, with the use of a combined solution of 15% of Ethephon with 5% of dimethylsulfoxide.
Interestingly, during the period that no exploration of Arabic gum at the producing areas (Sudan, Nigeria and Kenya) is realized; the production of cashew gum in Brazil is high, indicating that Brazil should be able to export the product.
