The present invention anti-cariogenic activity of erythritol. The invention further discloses the use of erythritol in food preparations as an at least partial replacer of sugar or other cariogenic sweetening agent. Erythritol is used in combination with normally employed sweetening agents and the favourable characteristics of the erythritol are preserved while the amount of erythritol used is much less than what would be needed to replace the sugar completely.

Why it's free to use
- Filed April 18, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 18, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 18, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
