For many dairies, controlling and verifying the lactose concentration in lactose-free and low lactose dairy products is challenging because many of the methods available are not optimal. Current methods tend to be imprecise, slow and laborious or expensive – or any combination of these.

Without access to a fast and precise method for lactose concentration measurement, dairies may have to wait for days to get a result for product release – or release batches based on “typical” results and not have batch-specific concentration data available for all productions.

The LactoSens® test is a direct assay on a biochip that very specifically measures residual lactose in mere minutes in an expanded range of lactose-free and low lactose dairy products. The new LactoSens® supports testing with flavors like coffee and chocolate. Validated against the HPLC reference method, LactoSens® is available in the following three versions:

For use with Ha-Lactase™:

• LactoSens® 0.02% - concentration range 0.02-1% very useful for low-lactose products
• LactoSens®R - concentration range 0.008-0.2%, the product for lactose-free batch release

For use with NOLA® Fit lactase:

• LactoSens®R for NOLA® Fit - concentration range 0.008-0.2% , for batch release of NOLA® Fit produced lactose-free dairy products
