Hydrolysis of resin in pulp

Abstract From the Canadian patent

Resin can be hydrolyzed enzymatically during the peroxy bleaching (e.g. with hydrogen peroxide) commonly used in pulp manufacture and the use of lipase in the manufacture of CTMP-fluff will afford several significant advantages, such as a pronounced reduction in fats, low time-consumption, since the process can be carried out in less than one calendar day, no losses in brightness or yield, or only marginal brightness and yield losses and low handling, costs. The enzyme treatment during bleaching necessitates little or no change of commonly used bleaching conditions. As a further advantage, the peroxy bleaching is mostly made at alkaline pH whereby the liberated fatty acids remain ionized …
