The invention provides a process for the production of yeast extracts which exhibit novel and interesting flavours. The process comprises the enzymatic hydrolysis of a mixture of yeast protein and non-yeast protein. Suitable non-yeast protein sources include soya bean meal and whey solids. The hydrolysis may be effected by the enzymes responsible for the autolysis of yeast or additional enzymes may be added to the mixture. The water-soluble fraction from the hydrolyzed mixture is concentrated to form pastes for use in foodstuffs.

Why it's free to use
- Filed April 19, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 19, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
