Claims
- 1. Process for preparing a flavour concentrate, comprising the steps of:
- (a) mildly oxidising triglyceride fat, which comprises at least 50 wt. % milk fat, to such a degree that the ratio of the anisidine value and the iodine value obtained exceeds 0.05, wherein the fat is oxidized by maintaining it at a temperature of at least 50.degree. C. for more than 30 minutes, and
- (b) hydrolysing the triglyceride fat in the presence of water at increased temperature of above 110.degree. C. and/or increased pressure exceeding 1.5 bar during a period of time sufficient to obtain a degree of hydrolysis exceeding 10%,
- wherein step (a) is carried out prior to or simultaneously with step (b).
- 2. Process according to claim 1, wherein step (a) involves oxidizing the fat to such a degree that the anisidine value of the fat is increased by at least a factor 1.5.
- 3. Process according to claim 1, wherein the step (a) the fat is oxidized in the presence of at least 0.1%, preferably at least 0.2% water by weight of the fat.
- 4. Process according to claim 1, wherein the hydrolysis of the triglyceride fat is effected by maintaining said fat at a temperature above 130.degree. C.
- 5. Process according to claim 1, wherein the hydrolysis is carried out in the presence of a gas phase containing less than 5 wt. % of oxygen.
- 6. Process according to claim 1, wherein the hydrolysis is initiated starting from a composition containing at least 1% of water by weight of the triglyceride fat.
- 7. A method of flavoring food products comprising incorporating in the products the flavour concentrate obtained according to claim 1.
- 8. The method according to claim 7 wherein the flavour concentrate is incorporated in the food products at a concentration in the range of 0.01% to 1.0% by weight of the food product.
