Abstract: According to an example aspect of the present invention, there is provided a method of producing films from nanocellulose based raw materials having high consistency and thereby providing low energy consuming and feasible manufacturing process of CNF films and film materials.

Abstract: The present invention provides a method for producing fibrillated cellulose, the method comprising providing pulp, treating said pulp at a consistency of at least 10% with a cellulase, and fibrillating said pretreated pulp to obtain fibrillated cellulose. The present invention also provides a nanofibrillar cellulose product.

Abstract: The present invention provides a method for determining carbonyl ratio and/or concentration of oxidized nanofibrillar cellulose in a sample. In accordance with the invention oxidized nanofibrillar cellulose comprised in the sample is enzymatically hydrolyzed into oxidized cellobioses which are specific markers to oxidized nanofibrillar cellulose. The cellobioses may be then analyzed and quantified to reveal the amount of oxidized nanofibrillar cellulose in the sample. A method for determining the concentration of oxidized nanofibrillar cellulose in a sample comprises steps of providing an analytical sample of material comprising oxidized nanofibrillar cellulose; hydrolyzing the analytical sample to breakdown products of oxidized nanofibrillar cellulose in presence of one or more enzymes; subjecting the breakdown products to a separation analysis to reveal the relative amounts of the breakdown products; and determining the concentration of oxidized nanofibrillar cellu-lose.

Abstract: The present invention relates to a process for producing a fibrillated cellulose material. In the invention fibrillated cellulose is produced enzymatically by using a low energy demanding mechanical mixer such as plough share mixer, to enhance the fibrillation. Enzymes and process conditions are chosen so that the cellulose degradation is as low as possible, while obtaining a high yield of nanofibrils. Sugars that are produced into the end-product may also be furthermore exploited.
