Tamarind Kernel Powder (TKP) has a variety of industrial applications as thickener, stabilizer, gelling agent etc. in food and feed, pharmaceutical, textile, oil exploration etc. The quaternary ammonium compounds of Tamarind Kernel Powder (Q-TKP) were prepared by the reaction of TKP with triethylamine-epichlorohydrin condensate in presence of sodium hydroxide and sodium hypochlorite under different reaction conditions. Variables studied were concentration of TKP, sodium hydroxide, amine-epichlorohydrin condensate as well as reaction time and temperature. The nitrogen content and degree of substitution of the Q-TKP samples were determined. Rheological studies of quaternized Tamarind Kernel Powder solution exhibited non-Newtonian pseudoplastic behavior, cold-water solubility and solution clarity.
