Technical Abstract: Currently, the activities or strengths of commercial dextranases in the U.S. cannot be directly compared because there is no uniform method used by vendors and/or distributors to measure the activity. A very wide variation exists in the activities of commercial dextranases, and this is compounded by the fact that activities and prices change regularly. Moreover, the factory storage characteristics of commercial dextranases differ enormously, which further highlights the need for not only a uniform method to (a) measure and economically compare the activities of different commercial dextranases, but (b) one which can be used simply at the sugarbeet factory to measure the activity of factory delivered batches of enzymes, and their changing activities on factory storage. A dextranase activity method, based on simple titration, was identified and modified for easy use a the sugarbeet factory. This method does not need any sophisticated equipment and there is no need for standards and a standard curve.
