A non-ionic seed-gum from cassia corymbosa

Carbohydrate Research, 1984
Abstract A polysaccharide has been extracted from Cassia corymbosa seeds with cold, acidulated water, and purified to give a water-soluble product containing d -galactose and d -mannose in 4:7 molar ratio. Acid-catalyzed fragmentation, periodate oxidation, methylation, and enzymic hydrolysis showed that the seed gum has a branched structure ...

Physicochemical Characterization of Seed Gum from Cassia Fistula

Key Engineering Materials, 2019
Cassia fistula gum was purified and modified by isopropanol precipitation and carboxymethylation process respectively. The physicochemical property of both purified and modified gums were evaluated and compared to their crude gum. The mannose to galactose (M/G) ratio of purified gum was altered by purification process.

Chemical modification of Cassia occidentalis seed gum: carbamoylethylation

Carbohydrate Polymers, 2005
Abstract The seeds of Cassia occidentalis, an annual weed occurring throughout India, is a rich source of galactomannan gum. The gum derived from seed endosperm can be potentially utilized in a number of industries to replace the conventional gums. With a view to utilize the gum for broader applications, carbamoylethylation of C.

Structural elucidation, modification and characterization of seed gum from Cassia javahikai seeds: A non-traditional source of industrial gums

International Journal of Biological Macromolecules, 2009
A water-soluble seed gum was isolated from seed endosperm of Cassia javahikai. The acid-catalyzed fragmentation, methylation, selective enzymatic degradation and periodate oxidation suggested a heteropolymeric structure for the polysaccharide. The polysaccharide was shown to have a linear chain of beta(1-->4) linked d-mannopyranosyls units with side ...

Determination of the optimal reaction conditions for the preparation of highly substituted carboxymethyl Cassia tora gum

Carbohydrate Polymers, 2017
Highly substituted carboxymethyl Cassia tora gum (CM-CTG) was prepared from CTG by treatment with monochloroacetic acid (MCA) in ethanolic aqueous solutions after alkalization under different reaction conditions. The influence of the etherification temperature, alkalization and etherification times, molar ratio of sodium hydroxide to MCA (nNaOH/nMCA ...

Valorization of Cassia tora Seeds: Extraction and Biofunctional Characterization of Cassia tora Seed Gum

Biopolymers
ABSTRACTCassia tora, an annual shrub, is a promising but underexplored source of galactomannan, comparable to widely used sources, such as fenugreek, guar, and locust bean. Galactomannans are heteropolysaccharides composed of galactose and mannose, valued for their role as dietary fibers and texture modifiers in food applications.
