一般描述

来自阿拉伯胶树的阿拉伯胶,是从阿拉伯胶树塞伊耳相思树的枝条中提取的。它是一种可食用的干燥胶状渗出物。阿拉伯胶具有高溶解度,可用作食品工业中的稳定剂、乳化剂、调味剂、增稠剂和表面处理剂。它会引起糖的混浊或阻碍糖的结晶。阿拉伯树胶抑制葡萄酒生产中的色素沉着和蛋白质沉淀。

应用

来自阿拉伯胶树的阿拉伯胶已被用作:
  • 用作确定虾中脂肪酶活性的乳化剂
  • 用于苔藓纤维发芽的可视化
  • 作为一种免疫原,并在板捕获抗原 ELISA(PTA-ELISA)中包被微量滴定孔
  • 用于免疫组织化学的银增强
  • 作为Timm 染色解决方案的一个组成部分
  • 在基于硝酸纤维素的土壤粘附测定中
  • 将少量石墨烯(FLG)与块状石墨层分离

其他说明

被认为是半乳糖、鼠李糖、阿拉伯糖和葡糖醛酸的分支聚合物的钙、镁和钾盐,分子量约为250,000。

  5. Can Product G9752, Gum arabic from acacia tree, be used to extract nuclei from ciliate cells?

    This product has been cited for use in a lysis buffer to extract nuclei from ciliate cells.  The reference is J. Eukaryotic Microbiology, 43(3), 198-202 (1996).

  6. Can you provide a description of the polysaccharide in Gum arabic from acacia tree, Product G9752?

    The polysaccharide in gum arabic is branched with a main chain of (1->3) linked β-D-galactopyranosyl units, with side chains of (1->3) β-D-galactopyranosyl units joined to it by (1->6) links. The side chains are two to five units in length. Both main chains and side chains have attached units of α-L-arabinofuranosyl, α-L-rhamnopyranosyl, β-D-glucuronopyranosyl and 4-O-methyl-β-D-glucuronopyranosyl units.

  7. What is the solubility of Product G9752, Gum arabic from acacia tree?

    According to the chemicals encyclopedia published by the Royal Society of Chemistry, 12th ed., Entry# 11, gum arabic is insoluble in alcohols. It is almost completely soluble in twice its weight of water. It is soluble in glycerol and in propylene glycol, but prolonged heating may be necessary for complete solution.
