Production of Gum from Cashew Tree Latex
نویسنده
چکیده
This research is aimed at producing gum from cashew tree latex, which can act as substitute for gum Arabic. The method used include drying and size reduction of the exudates gum, sieving of the gum to remove impurities, dissolution of the gum in distilled water, filtration to remove polysaccharide waste and finally concentration and stability of the gum. Glycerine, starch and Zinc oxide are some of the additives used in stabilizing the gum. The pH and Viscosity on addition of various percentage concentration of stabilizing agent were determined. Gum of the best quality was obtained with viscosity and pH of 4.52 Ns/m and 4.2 respectively; this is because the natural pH of gum from Acacia Senegal ranges between 3.9 4.9. The gum can be used as an alternative for synthetic adhesive used presently for stamps and envelopes.

Water flux in a young, 4-year old, cashew (Anacardium occidentale L.) plantation was studied over a dry season, from November 2001 to March 2002, in the forest-savannah transition zone of Ghana, West Africa. The temperature-difference method was used over this five-month period to quantify the diurnal and day-to-day whole-tree sap flow (Qt) and hence the canopy scale transpiration (Ec). M...

Food allergy affects many young children and tree nut allergy is accountable for a large number of severe, life-threatening anaphylactic reactions. Cross-reactivity can occur not only with foods that are in the same biological family but also between certain fruits or vegetables and latex (latex-fruit syndrome). We present the case of a previous healthy 5-year-old girl referred to Pediatric/All...
