Abstract From the Canadian patent

Compositions useful as high temperature media are disclosed which are blends of fatty acid esters and aliphatic ethers. the fatty acid esters have iodine numbers of at least about 10 and are preferably lipids derived from vegetable animal, or marine, sources. Reduced calorie high temperature cooking compositions suitable for frying applications and exhibiting greatly improved resistance to thermal degradation may be obtained by the use of an esterified alkoxylated polyol as the aliphatic ether component.

Why it's free to use

  • Filed December 10, 1990 and granted August 24, 1999. 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.
