INTRODUCTION

Lumex Instruments proposed the method for determination of lactose content in lactose-free milk processing products by capillary electrophoresis (CE).

For the determination of lactose, fructose, glucose, and saccharose content in other types of products (including determination of lactose in products with lactose content of less than 1 %), it is recommended to use Lumex Instruments set No. 0300002753.

MEASURING METHOD

The method is based on extracting the component from samples with distilled water, obtaining derivatives, further separation, identification and determination of the mass concentration of lactose by capillary electrophoresis.
The component is detected at a wavelength of 305 nm.
