Hydroxypropyl guar is one of the industrially significant biopolymers. In the present study, hydroxypropylation of guar gum was investigated using Taguchi's L9 orthogonal array design of experiment. Reaction conditions were optimized to obtain higher hydroxypropyl content (%) in the derivatized sample. The optimized conditions comprised 7 mL and 0.12 g of propylene oxide and NaOH respectively, keeping the methanol: water ratio 7 : 3, and reaction time 3 h at 60°C. The hydroxypropyl content of the derivative synthesized under optimized reaction conditions was determined as 0.830 %. The structural changes introduced by the modification were corroborated by FT-IR, 1-D ( 1 H, 13 C, and DEPT-135), and 2-D (HSQC, HMBC, and COSY) NMR spectroscopic analysis. Thermal studies of the hydroxypropyl derivatives vis a vis native guar using TGA, DSC, and DTG indicated better thermal stability of the hydroxypropyl derivative in comparison to the native guar gum. The studies demonstrate that Taguchi's L9 orthogonal array is a statistically sound approach for hydroxypropylation of guar gum involving lesser number of experiments than the conventional approach.

“…The hydroxypropyl group is also utilized to prepare cross-linked [6] products. However, the introduction of new groups is significantly influenced by different reaction factors including, temperature, concentration of etherifying and catalyzing reagent, [7,8] composition, [8] reaction time [9] and state of the reaction medium, [10] etc.…”

Novel nanocomposites reinforced fibrous casing of sugarcane bagasse containing with nanocarbon and nanoclay (0.5 and 1% wt) were developed to evaluate the adsorption effects of 4 carcinogenic polyaromatic hydrocarbons [benzo[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene(PAH 4)] during the smoking process of dried sausage. The mechanical, water vapor permeability (WVP), migration, film opacity, thermal properties, morphology, and the adsorption efficiency of produced films were assessed. It was observed that additions of nanocarbon and nanoclay to the film formulation led to significant improvement in tensile strength, elongation at break, maximum load stress, and elastic modulus values compared to control film. WVP in the nanocomposite was reduced by 40% along with the addition of nanoparticles. Film opacity, melting temperature, crystallization temperature, crystallinity degree, and glass transition temperature were remarkably increased. The migration levels of neat nanomaterials in ethanol and isooctane ranged from 45 to 107 mg kg–1. These improvements were more highlighted when nanoclay nanoparticles (1% wt) were used compared to nanocarbon. The nanoclay nanocomposite indicated uniform and well-distributed nanoparticles. Based on the GC–MS analysis, reinforced sugarcane bagasse fibrous casing with nanoclay particles efficiently adsorbed the PAH 4 compared to control and nanocarbon reinforced nanocomposite film.
