New thickening agents based on tamarind seed gum and karaya gum polysaccharides

A review study on chemical composition and molecular structure of newly plant gum exudates and seed gums

“…They explained that the emulsifying property of KG might be due to the presence of fatty acids in the gum structure. KG has been used in pharmaceutical, leather, bakery and dairy products due to specific functional characteristics such as suitable water holding capacity (WHC), oil holding capacity (OHC), foam capacity and stability, thickening properties, emulsification capacity and bulk density (Anderson, McNab, Anderson, Braown, & Pringuer, 1982;Ibrahim, Abo-Shosha, Allam, & El-Zairy, 2010;Galla & Dubasi, 2010). It can be also utilized as a thickener in textile printing (Davidson, 1980) and drug release controlling agent (Munday & Cox, 2000).…”

“…KG is a partially acetylated complex polysaccharide gum involving high molecular weight strcuture. The chemical structure of KG is composed of 55-60% of neutral monosaccharide residues (namely galactose and rhamnose), 8% acetyl groups and 37-40% uronic acid residues (galacturonic and glucuronic acid) (Davidson, 1980;Ibrahim, Abo-Shosha, Allam, & El-Zairy, 2010;Stephen & Churns, 1995). Vinod et al (2010) also reported the presence of the aspartic acid (64.2 ± 2.44 lg/g), proline (30.5± 1.86 lg/g), glutamic acid (34.2 ± 1.44 lg/g), threonine (25.2 ± 1.06 lg/g) and glycine (4.8± 0.45 lg/g) and leucine (3.9 ± 0.28 lg/g) in the chemical structure of KG.…”

Activated carbons derived from tamarind seeds for hydrogen storage

“…10 hydrogen uptake. In addition, these activated carbon materials also show a high hydrogen uptake of 7.7 wt% at 77 K and at 1 MPa [26]. This may be attributed to the high specific surface area and micropore volume of the samples which adsorbs hydrogen by physisorption, while the metal hydrides adsorb hydrogen by chemisorption process [36].In order to confirm the hydrogen storage capacity of these samples, two batch samples of MWTSC-50-3-700 were prepared and hydrogen adsorption capacity was measured and found to be in good agreement with previous batch sample as shown in Fig.…”

“…The Tamarind Kernel Powder is normally used in industries like textile, dying and Printing, jute, card board, mosquito coil, food additive, oil well drilling, paper industry etc. [25,26]. The botanical name is Tamarindus indica L. and India is the major producer of tamarind on a large scale.…”

New Thickening Agent Bases on Aloe Vera Gel for Disperse Printing of Polyester

“…This reflects the positive effect of urea component on enhancing the swellability of the fabric structure, retarding the evaporation of water during drying, overcoming the moisture sensitivity, in addition to increase water condensation of the prints during the steaming step thereby enhancing both the extent of dye interaction and fixation on and/or within the fabric structure. [11][12][13] Beyond 50g urea/kg paste there is a noticeable decrease in the depth of shade, which could be discussed in terms of side interactions with the used thickener thereby altering their rheological properties and facilitating undue penetration of the used disperse dye, i.e. lower extent of dye fixation.…”
