Open the CIPO recordAbstract From the Canadian patent
To produce evaporated whole milk sterilized without non-lactic additives, the standardized milk is subjected to homogenization or a natural lactic emulsifier is added to the standardized milk, followed by two heat treatments before and after concentration by evaporation. The evaporated milk is sterilized after packing in containers or online before packing, in which case the containers are filled under aseptic conditions. The evaporated milk obtained keeps at room temperature without forming deposits, without gelling and without any separation of fats.

Why it's free to use
- Filed December 10, 1990 and granted October 2, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 10, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 10, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
