Rapid triglyceride assay for use in pulp pitch control

Abstract

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 the sample in the presence of a lipase to form glycerol and fatty acids, and then determining the difference between the amount of free glycerol present in the 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 the amount of triglycerides present at various sample points in pulp and paper mills, which advantageously serves as a diagnostic tool for use in controlling the undesirable deposition of pitch during the papermaking process.
