Open the CIPO recordAbstract From the Canadian patent
Starch hydrolysates having a D.P. of about 20 to 200 and a D.E. of about 0.5 to 5 are used as fat replacements in food. The starch hydrolysates are prepared by heating granular starch containing at least about 20 weight percent amylopectin in an acidic slurry of water and a water-miscible organic solvent such as ethanol. The slurry is heated under conditions which do not gelatinize the starch but cleave at least about 20 percent of the terminal amylose groups from the amylopectin molecules.

Why it's free to use
- Filed May 10, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 10, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 10, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
