RAPID TRIGLYCERIDE ASSAY FOR USE IN PULP PITCH CONTROL

摘要

Enzymatic methods are provided for determining the surface triglycerides content in a sample of wood pulp. The methods preferably comprise reacting triglycerides which are present on the surface of the wood pulp fibers in th e sample in the presence of a lipase to form glycerol and fatty acids, and the n determining the difference between the amount of free glycerol present in th e sample and the amount of glycerol formed from said triglycerides. The method is useful as a quick, portable, accurate, and low cost assay for assessing t he amount of triglycerides present at various sample points in pulp and paper mills, which advantageously serves as a diagnostic tool for use in controlli ng the undesirable deposition of pitch during the papermaking process.
