“…Microwave irradiation using only hot water allows milder reaction conditions, which offer lower production costs, minimization of wastes when compared with the use of alkalis, and maintains the physicochemical characteristics of crude polysaccharides. It has been reported for a variety of matrices including corn pericarp, wheat bran, flax shives, tamarind kernel, mulberry leaves, brewers' spent grain, watermelon rinds, tea flower, mushrooms, or traditional Chinese medicinal plants . The control of MWE extraction conditions is important to limit hydrolytic cleavage of polysaccharide chains or alter the compositions that would enrich in some monomers .…”

The development of environmentally friendly processes with limited generation of polluting streams to attain sustainable utilization of raw materials is encouraged. The implementation of novel extraction technologies more efficient, selective and with lower energy consumption than conventional ones, can help in achieving this objective. Particularly promising are aqueous based methods, since water is a cheap, safe and abundant solvent and the limited use of toxic organic solvents is a consumeŕs, ecological and processing demand. The benefits and the limiting aspects of microwave assisted water extraction, either adding water as the only solvent or in solvent free processes, using the naturally present water in vegetal materials for the extraction of valuable components from renewable vegetal sources are highlighted and the potential of this technique for industrial applications is discussed.Microwaves (MW) are radiation of the electromagnetic spectrum ranging in frequency from 300 MHz (radio radiation) to 300 GHz J Chem Technol Biotechnol 2015; 90: 590-607

“…From our previous work, it was found that these two types of tamarind seed had a slightly different extent of the husk and the kernel components [8]. The dye powder which was to be used for dyeing the cotton and silk fabrics, was the soluble part accounting for about 55% by weight of both tamarind seed husks.…”

“…In our previous work [8], the extracted tamarind kernel which composes mainly of the hetero-polysaccharide compound, xyloglucan, was studied to use as a thickener for pigment printing on cotton fabric. The results found that the prepared tamarind gum had desired thickening properties for textile printing, providing color yield and rubbing fastness of the print comparable to those of the commercial synthetic thickener printing.…”

Abstract-This research studied the extraction of the natural dye from two different types of tamarind seed viz. sour-tamarind seed (TF) and sweet-tamarind seed (TO). The extracted dye solutions were prepared into a powder form and subsequently used for dyeing cotton and Bombyx Mori silk and Eri silk fabrics. From the experiment, the TF dye powder was easier soluble in water and could render a higher color strength than the TO dye powder. It was found for the tamarind-seed dyes that they could better exhausted on the silk fabrics than the cotton. Between the two silk fabrics, the dyes illustrated a higher degree of exhaustion on Bombyx Mori silk fabric than the Eri counterpart. The tamarind-seed dyes provide a reddish brown shade on the fabrics. This reddish brown shade could be altered when the dyed fabrics were put through the washing process. After washing, the shade of the dyed fabrics was more intense. The color fastness to washing of the dyed fabrics was in a good-excellent level. Even after experiencing 5-time washing, no significant shade change was observed on the dyed fabrics. The effect of mordants on the dyed fabrics was studied using three different mordants which were ZnSo 4 , K 2 Cr 2 O 7 and FeSo 4 . The ZnSo 4 mordant was found to enhance the color fastness to washing to the dyed fabrics without causing any shade change, while using K 2 Cr 2 O 7 as a mordant led to a shade alteration into a yellow brown but helped to stabilize the dye molecule, so such shade obtained was not sensitive to the washing condition. For the FeSo 4 mordant, it also caused the shade change on the dyed fabrics to a dull grey shade but providing an excellent color fastness to washing.

“…Its molecular weight ranges from 720 to 880 kDa (Freitas et al, 2005). Xyloglucan contains the major soluble sugars such as pentose (20%), mannose (17%-35%), and glucose (11%-80%) (Tepparin et al, 2011). When dissolved in water, it forms a viscous solution (Sumathi & Ray, 2002) and is utilized as an emulsifier, fiber, and rheology modifier in various applications (Gupta et al, 2010).…”

Tamarind (Tamarindus indica L.) is mostly cultivated for its fruits, which is consumed fresh or processed and used as a seasoning or spice component in various food formulations. It is well known for the pulp (40%), which is a good source of vitamin C and acids such as citric, malic, and tartaric, as well as sugars, which are responsible for its sweet-sour flavor (Caluwé et al., 2009). Pulp mostly contains tartaric acid (8% to 18%) and is extensively used in formulations of tamarind based drinks, curries, sweet meats, and chutneys (Rao et al., 1999).It is believed that tamarind is native from Africa, but currently it is cultivated all over South East Asia, America, and Australia (Indiaagronet, 2021). India is one of the leading producers of tamarind and its products. It is grown mainly under rainfed conditions and cultivated throughout India, mostly in Tamil Nadu (30.12%), Karnataka (23.94%), Kerala (16.26%), Andhra Pradesh (12.23%), Telangana (8.79%), and Maharashtra (2.86%) (Table 1).The various parts of the tamarind tree, such as leaves, shells, pulp, fiber, and seeds, apart from their domestic use, find application in several industries such as food, pharmaceuticals, fuel, electrochemical, textile, construction, agriculture, automobiles, packaging, treatment of industrial effluents, and composite industries (Ghaffaripour et al., 2017). The raw material obtained from the tree must be processed, extracted and modified before it is used in industrial applications: 90% of its production is consumed directly, with the remaining 10% exported as fresh, dried, or processed products (Israel & Murthy, 2019).
