Open the CIPO recordAbstract From the Canadian patent
A reduced calorie dairy mix for use in frozen dairy desserts and yoghurt is made from milk and/or milk products that have been treated with a lactase/beta-galactosidose enzyme which hydrolyzes lactose to glucose and galactose. This increases sweetness reduces lactose crystallization problems and creates a greater freezing point depression. Aspartame or other high potency sweeteners may be added without the need for additional bulking agents and/or bulk sweeteners.

Why it's free to use
- Filed August 1, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 1, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 1, 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.
