Studies of Decolourization of Cane Juice Using TiO2 Pellets

Abstract

Prototype expert system has been developed for decolourization of cane juice. Though much work has been done in the direction of removing colour in the clarification process during sugar manufacture but much success has yet not been achieved. Conventional clarification process cause environmental problem. TiO₂ catalyst has emerged as an effective alternative method. In the present study, attention has been paid decrease the pigments, which causes sugar colouration, cane juice treated with TiO₂ pellets during clarification process. The experiment supported that the TiO₂ pellets work achieve significant decrease of polyphenols due to their reduction in to derivatives. The decolourization efficiency was found to be in the range the 64-40 % at 470 nm for TiO₂ pellets. Most attention has been given to TiO₂ because of its high catalytic activity resistance to corrosion, biological immunity low cost and no formation of toxic intermediate products.
