The FDA’s guidance to control the amount of lactose in food and supplements states lactose must not be present, so manufacturers are dependent upon the level of detection for analytical methods. Eurofins Food Chemistry Testing Madison, Inc. has recently optimized our High-Performance Anion Exchange Chromatography method for low lactose determination to improve upon the accuracy and specificity obtained across a variety of different product types when quantifying at low concentrations.
