Publisher Summary This chapter discusses plant gums and mucilages. Plant gums is defined as those substances of plant origin that are obtained as exudations from the fruit, trunks, or branches of trees spontaneously, after the mechanical injury of the plant by the incision of the bark or by the removal of a branch, or after invasion by bacteria or ...

The Analysis of Plant Gums and Mucilages
1955The gums and mucilages are hydrophilic colloids of high molecular weight. Some are completely soluble in water, forming viscous solutions of gels, others swell and absorb considerable quantities of solvent without dissolving. They are not soluble in the common organic solvents.

Studies on bacterial capsular poysaccharides and on a plant gum.
1981The structure of the capsular polysaccharides from Klebsiella serotype K60 and K26 have been determined using the techniques of methylation.periodate oxidation,partial hydrolysis, and β-elimination. ¹H- and ¹³C-n.m.r. spectroscopy was used to establish the nature of the anomeric linkages in both polysaccharides and also in the oligosaccharides obtained

Differential thermal studies on plant gums
Journal of Polymer Science, 1962AbstractDifferential thermal analysis studies have been done on nine different gums belonging to different families and genera and differing in their chemical constituents and structure, along with their respective gum acid and hydrolysis products. The gums studied include gum sterculia urens, gum azadirechta indica, gum acacia catechu, gum limmonia ...

Effect of plant gums on thermal polymerization of acrylonitrile
Journal of Applied Polymer Science, 2002AbstractThe effect of some plant gums on the polymerization of acrylonitrile (AN) using ceric ammonium nitrate (CAN) as an initiator in the presence of air (containing 21% oxygen) was studied. The induction period and percent conversion were determined. The induction period in the presence of gum was comparatively lower than that under a N2 atmosphere.

Plant gums of the genus Khaya. Part V. Further studies on Khaya senegalensis gum
Journal of the Chemical Society C: Organic, 1970The fractionation of deacetylated Khaya senegalensis gum has been re-examined. The main component of the gum, polysaccharide A, has been converted into the carboxy-reduced derivative, and oligosaccharides formed on acetolysis of the modified polysaccharide have been shown to include 4-O-rhamnopyranosylgalactose (I), 4-O-galactopyranosylgalactose (II ...

Industrial gums from plants: Guar and chia
Economic Botany, 1982Water soluble gums of plant origin represent an enormous quantity of industrial material supplied by plant growing areas in most parts of the world (Whistler, 1973). Gums come from a variety of plants and are separated by a variety of methods. Their use began before recorded history, starting in all probability as thickeners for foods in gruels, long ...
