“…Xyloglucan in tamarind seeds is a water-soluble, edible polysaccharide; with high viscosity, broad pH tolerance [7], high thermal stability [2], and adhesivity [4]. These properties, lead to its applications as an emulsion stabilizer [9], food thickener, gelling agent, and a binder in the food and pharmaceutical industries [3].…”

“…Xyloglucan is used in the preparation of confectionery products, salad dressings, frozen desserts, beverages, and sweets [4], [9]. Xyloglucan normally forms a gel in the presence of alcohol, sugar, and @ @ @ polyphenols, even in cold water or milk [7], [9]. Unlike fruit pectin which undergo degradation on boiling, xyloglucan is not affected by boiling in neutral aqueous solutions [7].…”

“…Xyloglucan is used in biotechnological processes, due to its characteristics such as non-Newtonian flow behavior, water-holding ability, and resistance against heat, salt, and pH regions, making it a suitable biomaterial in tissue engineering [9]. Due to the extraordinary similarity of xyloglucan with mucins, it is used in producing artificial tears for ophthalmic application as an effective treatment for dry eye syndrome and also for ocular administration of both hydrophilic and hydrophobic antibiotics [2].…”

Natural polymers have captivated the food, cosmetic and medical industries lately, due to their much desired properties such as non-toxicity, non-carcinogenicity, biodegradability, and biocompatibility. Xyloglucan is one of the natural polymers, with a wide array of applications. Tamarind seed which is mostly a wasted product in the tamarind pulp industry is highly rich in xyloglucan. The tamarind kernel powder obtained from tamarind seeds can be used to extract the natural tamarind xyloglucan polymer. In this study, eight treatments were used: with two solvents based on; methanol and ethanol, and four different pH values; 5, 6, 7, and 8; to determine the most efficient protocol for tamarind xyloglucan extraction. Three replicates were used for each treatment and the yield and extractability were recorded. All the parameters were tested with one-way ANOVA, and the means were compared with Duncan’s Multiple Range Test. Methanol was found to be a better solvent than ethanol and resulted in a higher xyloglucan yield. The highest extractability was obtained at pH 7 (52.90±2.41%) and 8 (49.07±1.17%) which had no significant difference (p<0.05) between each other. Fourier-transform infrared spectroscopy spectrum was obtained to confirm the presence of the specific functional groups in the extracted xyloglucan. X-ray diffraction pattern indicated the diffraction peak at 2θ value of 20.05o confirming the extraction of high-quality xyloglucan which was in amorphous nature.

In an offshore system, hydrocarbon fluids are produced at deeper depths in the oceans, and extended pipelines delivering fluids over long distances are common. Subsequently, these practices increase the tendency of unprocessed water-containing hydrocarbon fluid to be exposed to lower temperatures and higher pressures conditions where hydrate formation is favourable. One of the solutions to resolve this problem is by introducing hydrate inhibitors preferably low dosage hydrate inhibitors (LDHIs). The more versatile LDHIs; Kinetic Hydrate Inhibitors (KHIs) could further be optimised in cost and its biodegradation properties. The current study used an ionic, neutral, hydrophilic, mucoadhesive and highly branched Tamarindus indica L. polysaccharide (TSP). TSP as a new natural kinetic hydrate inhibitor due to its high methoxyl content. In this study, the polysaccharides were extracted using water-based extraction method which resulted in 61.3% yield. The performance of TSP in delaying the clathrate hydrates formation was evaluated based on the induction time recorded from the thermogram generated by a high pressure micro-differential scanning calorimeter device (HP-μDSC) at pressure of 5 MPa with subcooling degree of 17.3 °C. Three TSP concentrations (0.10 wt%, 0.25 wt%, and 0.50 wt%) were tested to determine the optimal concentration used to increase the delay time at the prescribed conditions while comparing it to a condition when there is no addition of TSP. The outcomes shows that TSP is able to delay hydrates formation at high degree of subcooling. The TSP works well at low concentration at high degree of subcooling while remain relatively economical and biodegradable.
