A stable and non-separable composition comprised of starch and oil can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the oil into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat.

Why it's free to use
- Filed April 21, 1995 and granted June 25, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 21, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 21, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
