Abstract

AbstractShort‐chain fatty acids are frequently responsible for off‐odours in unprinted paperboard. They are formed as microbiological metabolic products in the circuit water of the paper mill and are absorbed on the paperboard. A gas chromatographic method for detecting these organic acids is described which seems to be suitable for quality control of unprinted paperboards. The various off‐odours associated with paperboard can be explained via the specific composition of the fatty acids.
