AN72632: Fast and Sensitive Determination of Lactose in Lactose-Free Products using HPAE-PAD Be the first to rate this application

Description

The increased market demand for lactose-free products has created a need for a fast, reliable, and sensitive method to analyze these products. HPAE-PAD is one of the most powerful techniques for carbohydrate determinations. It is a well-established technique for lactose and lactulose determinations. In this work, we developed an HPAE-PAD method using the recently introduced Thermo Scientific™ Dionex™ CarboPac™ PA210-4µm column to separate lactose from other structurally similar milk sugars. Here we determined lactose in eleven lactose-free products (both dairy and baked) using HPAE-PAD.
