“…A peak at 5.14 ppm and another very small peak at 4.72 ppm were assigned to α- d -mannopyranose and β- d -galactopyranose units, respectively. 19 , 50 The 1 H NMR spectrum of CTG and CCTG showed characteristic chemical shifts clustered between 3.52 and 4.08 ppm for ring protons of mannose/galactose units. A prominent peak at δ 3.19 ppm, corresponds to the nine hydrogens of quaternary methylammonium groups ( + N(CH 3 ) 3 ), appeared in the spectrum of CCTG, which was found missing in the spectrum of CTG, clearly indicating the incorporation of quaternary ammonium groups onto the galactomannan backbone.…”

There has been a cumulative interest across the globe in substituting the synthetic materials with sustainable, economical, and biobased green alternatives for utilization in diverse industrial applications. Galactomannans are among the most important sustainable, biodegradable macromolecules abundantly produced by plants, which can be exploited for a range of end-use applications. Functionalization of the galactomannans may improve the physicochemical properties for diverse industrial applications. In the present study, the cationic derivative of Cassia tora gum, a 1:5 galactomannan, was synthesized under heterogeneous alkaline conditions using CHPTAC. The effect of each reaction parameter on the degree of substitution (DS) was investigated using Taguchi L 16 orthogonal array. The optimized cationic product with DS 0.28 showed promising results as a biopolymeric flocculant for wastewater treatment and as a wet strength additive for improving the physical strength of paper prepared from old corrugated carton for its recycling. The optimized product was characterized by advanced spectroscopic methods.

“…2) werer ecorded in order to confirm the incorporation of carboxymethyl substituent and quaternary ammonium groups onto CTG. In 1 H-NMR spectra, corresponding to α-and βanomeric confirmers of galactose and mannose units, signals were observed in the region from 4.8 to 5.3 ppm (Bigand et al, 2011;Tako et al, 2018). The 1 H-NMR spectrum of CTG (Fig.…”

Biopolymeric materials have been utilized for water treatments since ancient times.Consequently, there is a cumulative and persistent interest in the study of novel sustainable, inexpensive and natural biobased alternatives. Amphoteric derivatives of galactomannans are still unexplored and rarerly used materials to treat industrial wastes. The study was explored to synthesize and characterize amphoteric derivative of Cassia tora gum, a 1,5 galactomannan for its application as a potential adsorbent for mitigation of cationic (Malachite green) and anionic (Congo red) dyes by applying 'Taguchi design' (L9). The derivative was also studied for the conditioning of water using kaolin suspension. The results indicated that amphoteric derivative (anionic DS ~ 0.52 and cationic DS 0.197) is effective in maximum adsorption of Malachite green (73%) and Congo red (17 %) dyes and as a flocculant at a minimum dose of 10 ppm. The amphoteric derivative was characterized by Xray-diffraction, TG analysis and spectroscopic techniques.

“…The mix B stabilizer was dissolved in water while heated at 40°C because galactomannan can dissolve in water forming highly viscous and stable aqueous solutions (Dos Santos et al, 2015). The physicochemical properties of galactomannan depend on the proportion of mannose and galactose in the galactomannans (Tako et al, 2018). Mix A and B are mixed and stirred until they became homogeneous.…”

In the last decade, increasing trends towards the consumption of healthier foods have forced processors of high-fat products (ice cream) to shift their formulations to higher proportions of unsaturated or “healthier” fats. Vegetable oils such as sunflower oil and VCO can be used as a substitute for milk fat, milk solids not fat (skim milk powder), sweeteners, stabilizers and emulsifiers, and mineral water in making ice cream. A study was carried out to determine the effects of the use of the ratio of sunflower oil: virgin coconut oil with palm fruit as a stabilizer in the production of ice cream on physicochemical properties (pH, proximate, overrun, viscosity, and melting rate). The use of palm fruit is based on the content of galactomannan in palm fruit. Premium ice cream with five different ratios of SO and VCO (15:0), (10:5), (7.5:7.5), (5:10), (15:0). The ice cream production involves mixing, pasteurization, homogenization, aging, and freezing. The physicochemical result shows ice cream sample with a ratio SO:VCO (5:10) obtained good physical properties, the lowest first-time drop/ shape retention, and a low melting rate compared to the others. The rheological behavior of ice cream is the non-Newtonian fluids with a pseudoplastic behavior. The apparent viscosity decreased with increasing shear rate.
