Hydrogen Peroxide Bleaching to Wine Corks with a Novel Catalyst

Abstract:

A novel catalyst CF-R for hydrogen peroxide bleaching to wine cork stopper was chosen to substitute the traditional imported item, and the corresponding bleaching process was studied. The influence of catalyst CF-R dosage, H₂O₂ concentration, bleaching temperature and time on cork whiteness and capillary effect were discussed. The optimized bleaching process for wine corks was obtained as follows: H₂O₂ concentration 14%, catalyst CF-R dosage 80g/L, bleaching temperature 70°Cand bleaching time 60 min. Comparing with the expensive imported catalyst, the amount of catalyst CF-R is greatly decreased, as is significant for not only cutting down the expenditure of chemicals, but also minimizing the burden on bleaching sewage disposal.
