Abstract - Before performing a " reductimétric "" determination of lactose in milk, it is essential to ascertain whether there was no more than 0;5 g of broken down lactose by litre.
That verification, which is till now carried out in about 40 hours by paper chromatography, can be completed in 2 hours, in the easier and the more inexpensive way, thanks to chromatography of silicagel in thin layer, whose process is described and discussed
