CL-10 Milk: Lactose

Lactose is a ß-galactoside. It is found at high concentration in milk
(≈130 mM) and milk products. It is one of the parameters defining the quality of the product and in many countries in the world, it enters the payment scheme.

International Dairy Federation (IDF) is the wordwide federation of the dairy sector which collaborates with ISO and AOAC International in the development of standard methods of analysis and sampling for milk and milk products.

IDF has published ISO 26462/IDF 214 Standard specifying an enzymatic method for the determination of the lactose content of milk and reconstituted milk by measurement of the difference in pH (differential pH measurement).

Advantages of Differential-pH automated method
With this enzymatic detection kit, stable and ready-to-use reagents, used in differential-pH technique (exclusively with CL-10 Plus instrument), results are obtained with operative simplicity and with the following benefits:

  • Improved accuracy and precision compared to the other methods
  • Objective reading of results
  • Results are stored on computer
  • Ready to use reagents
  • No sample preparation
