The Use of Cation-exchange Resins for the Hydrolysis of Sucrose in Plant Extracts.

Effects of Weak and Strong Cation Exchange Resins on Moisture Uptake Behavior of Ranitidine Hydrochloride

     The aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable H+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. Drug resin complexes (DRC) were prepared and evaluated for the percentage of moisture gain when placed in a humidity c...

Method for immobilizing invertase by adsorption on Dowex® anionic exchange resin

This communication describes a method for adsorbing the invertase (EC.3.2.1.26) on DOWEX® anion exchange resin. Among the types of DOWEX® resins studied (1x8:50-400; 1x4:50-400 and 1x2:100400), 1X4-200 was the most suitable, because it adsorbed the invertase molecules completely and the complex 1X4-200/invertase retained 100% of the catalytic activity. Moreover, no leakage of enzyme from the su...

Softening of Clear Juice

The removal of calcium and magnesium ions (softening) from clear juice can be beneficial to downstream processes. Such benefits include reduced evaporator scaling and the improved potential for the application ofion exclusion chromatography for additional sucrose recovery. The results of experiments in the laboratory and on a pilot plant scale are presented. These show that it is possible to so...

Comparison of adsorption equilibrium of fructose, glucose and sucrose on potassium gel-type and macroporous sodium ion-exchange resins.

Adsorption equilibrium of fructose, glucose and sucrose was evaluated on sulfonated poly(styrene-co-divinylbenzene) cation-exchange resins. Two types of resins were used: potassium (K+) gel-type and sodium (Na+) macroporous resins. Influence of the cation and effect of the resin structure on adsorption were studied. The adsorption isotherms were determined by the static method in batch mode for...
