Hydrolysis of plant seed gums by microwave irradiation

Carbohydrate Polymers, 2003
Abstract Under microwave irradiation (MW), the seed gums, guar and Ipomoea quamoclit were hydrolyzed to constituent monosaccharides and oligosaccharides in very mild conditions and short reaction time. Under MW both the seed gums could be completely hydrolyzed using very dilute acid (0.00625N H2SO4) within two minutes.

Studies on bacterial capsular poysaccharides and on a plant gum.

1981
The 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, 1962
AbstractDifferential 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, 2002
AbstractThe 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.

Studies on plant gums of the acacia group

2018
Although structural work has been carried out on gums from other Acacia species, including A.mollissima (Stephen, 1951; CHAPTER V - 125 - Young, 1963), A.pycnantha (Hirst & Perlin, 1954; Aspinall, Hirst & Nicolson, 1959), A.karroo (Charlson, Nunn & Stephen, 1955a), A.cyanophylla (Gharlson, Nunn & Stephen, 1955b), A.catechu (Hulyalkar, Ingle & Bhide ...

Industrial gums from plants: Guar and chia

Economic Botany, 1982
Water 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 ...
