Abstract: The present invention relates to a process for preparing a flavour concentrate, involving the steps of:(a) mildly oxidising triglyceride fat, and(b) hydrolysing the triglyceride fat to a degree of hydrolysis exceeding 10%.It was found that flavour concentrates of improved quality are obtained if prior to or simultaneously with the hydrolysis of triglyceride fat, said fat is mildly oxidised.

Abstract: The present invention is concerned with a flavor concentrate mainly consisting of glyceride fat and containing at least 0.6 ppm n-pentanal and/or at least 0.1 ppm n-nonanal and anti-oxidant at a concentration level in the range of 1 to 100 times c*. The present flavor concentrate may suitable be used to flavor food products.Another aspect of the present invention is a process for preparing a flavor concentrate by mildly oxidizing a fat-containing composition, comprising:(a) adding anti-oxidant to a fat-containing composition at a concentration level, calculated on the fat, of at least 1 to 100 times c*,(b) keeping the composition, in the presence of water, at a temperature of more than 50.degree. C. and at most the boiling temperature of the water under the conditions applied, during a period of time ranging from 0.5 hours to 1 week. The present process may not only beneficially be employed in the preparation of flavor concentrates from a butterfat containing composition but also by the oxidation of materials containing animal and/or vegetable fat.Other aspects of the present invention are a process for flavoring food products and a flavored food product obtainable by such a process.

Abstract: The present invention relates to a method for improving the flavor of starch by incubating the starch with an enzymatically active peptidase containing cell preparation under such conditions that enzymatic peptidolysis of a substantial amount of oligopeptides in the starch is the result, which incubation is, optionally, preceded or followed by a non-enzymatic purification step such as steam stripping or solvent extraction. The starch is suited for incorporation into food products, such as spreads.

Abstract: The invention relates to a method for the preparation of a yeast by degrading yeast with enzymes having RNA degrading activity leading to 5'-ribonucleotides, wherein oxidizing conditions are maintained during the enzymatic degradation. Preferably the proteolytic degradation is carried out under anaerobic conditions, and the RNA degrading activity leading to 5'-ribonucleotides under oxidizing conditions, such as an oxygen saturated incubation medium. The invention also relates to the yeast extract obtained, to the use of the yeast extract and to a flavouring and a food composition comprising it.
