The fatty acid residues of the fat have a ratio of C16 carbon and shorter chain fatty acids to stearic, oleic and linoleic acids C18 fatty acids of about 7.9 : 83.5 or less. The triglycerides present in the fat comprise at least 30% H2U triglycerides in which H indicates stearic and palmitic acids and U indicates oleic and linoleic acids. This allows production of an edible spread in which the fat phase is essentially a single, natural, vegetable fat or fat blend.

Why it's free to use
- Filed November 15, 1989 and granted February 11, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
