A low density, ready-to-serve frosting is provided that can be stored for extended periods of time with little or no separation of the aqueous and shortening phases and with minimal volume changes. The frosting is stablilized by the formation of an aqueous phase gel rather than by manipulation of the composition of the shortening phase. The aqueous phase gel comprises water and maltodextrin, water and inulin, or water and a mixture of maltodextrin and inulin.

Why it's free to use
- Filed October 31, 2002 and granted April 30, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 31, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 31, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
