The use of model systems containing purified anthocyanins, chlorogenic acid (CG), and blueberry polyphenol oxidase (PPO) and of different analysis methods (HPLC and polarographic methods) have allowed the study of the mechanism of anthocyanin degrada

Wood preservatives based on protein borates, both obtained by just mixed water solutions of protein and boric acid, as well as in the case of premanufactured protein borates salts are shown to be a good method to greatly retard the leaching of boron

Beech wood (Fagus sylvatica L.) condensate from a steaming operation was studied. The objective of our work was to study the precipitation of these wood extracts in presence of calcium ion after autoxidation at basic pH (8). The autoxidation was carr

In the present work, beech wood condensates are separated from the aqueous phase. Experimental results reveal an electrostatic interaction between the oppositely charged wood extracts after oxidation and Ca(OH)2. The increase in aqueous phase pH resu
