ABSTRACT The primary alcohol groups of ten polysaccharides, with widely different structures and water solubilities, were oxidized to carboxyl groups using 2,2,6,6-tetramethyl-1-piperidine oxoammonium ion (TEMPO) at pH 10.8 and 0°C. The yield and selectivity for the primary alcohol group were high for all ten of the polysaccharides. The oxidation greatly increased the water-solubility of the polysaccharides. Water-insoluble polysaccharides such as amylose, cellulose, and chitin became water-solu

As the researches to utilize nanotechnology in food science are advanced, applications of nanotechnology in various fields of the food industry have increased. Nanotechnology can be applied to the food industry for production, processing, storage, and quality control of foods. Nanomaterials, unlike conventional microscale materials, having novel characteristics can improve sensory quality of foods by imparting novel texture, color, and appearance. Nanotechnology has been used to design nanosenso

Chromobacterium viscosum lipase which has adsorbed on liposome and solubilized in microemulsion droplets of glycerol containing a little amount of water could catalyze the glycerolysis of olive oil. Studies on the continuous glycerolysis of olive oil by the immobilized enzyme was done at 37 degrees C in continuous stirred vessel bioreactor with polysulfone membrane. The effect of the flow rate of substrate (olive oil) in isooctane on the conversion and composition of the outlet was investigated

Abstract In the present study, the Δbackscattering (Δ BS ) method was developed as a simple and sensitive tool for determining the emulsion stability index ( ESI ) by backscattering light detection. The backscattering light detection method uses emulsion‐scanning technology to monitor physical behavior in an emulsion as a function of storage time. Emulsions were prepared by the homogenization (8,000 rpm for 2 min at 25C) of distilled water and perilla oil containing Tween 60, and the sample was

Chromobacterium viscosum lipase, solubilized in microemulsion droplets of glycerol containing small amounts of water and stabilized by a surfactant, could catalyze the glycerolysis of triolein. Kinetic analysis of the lipase-catalyzed reaction was possible in the reversed micellar system. Among surfactants and organic solvents tested, bis(2-ethylhexyl)sodiumsulfosuccinate (AOT) and isooctane were respectively most effective, for the glycerolysis of triolein in reversed micelles. Temperature effe

Calotropis procera R. Br., a traditional medicinal plant in India, is a promising source of commercial proteases, because the cysteine proteases from the plant exhibit high thermo-stability, broad pH optima, and plasma-clotting activity. Though several proteases such as Procerain, Procerain B, CpCp-1, CpCp-2, and CpCp-3 have been isolated and characterized, the information of their transcripts is limited to cDNAs encoding their mature peptides. Due to this limitation, in this study, to determine
