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 flavor generation. In particular the invention relates to a process for the preparation of a flavor composition. The process comprises combining glycerol with a quaternary ammonium compound, adding at least one flavor precursor to form a reaction mixture and heating the reaction mixture to form aroma compounds, wherein the glycerol is combined with a quaternary ammonium compound at a molar ratio ranging between 5:1 and 0.8:1. The flavor precursor comprises preferably an amino compound such as an amino acid. A further aspect of the invention is a food product comprising the flavor composition obtainable by the process of the invention.
Abstract:
A concentrated flavour base product, prepared by carrying out a thermal reaction between a tonality delivering ingredient and at least one thermal reaction precursor, and a method for preparing a culinary flavouring product from ingredients including a tonality delivering ingredient and other ingredients, comprising reacting the tonality delivering ingredient with at least one thermal reaction precursor to obtain an intermediate product and processing the intermediate product with the other ingredients to obtain the final culinary flavouring product.
Abstract:
Compositions are provided which contain immobilized flavorants, in the form of supramolecular complexes of flavorant compounds, for flavor delivery. One embodiment relates to the flavorant supramolecular complexes themselves; Other embodiments relate compositions which contain the flavorant supramolecular complexes and a substrate. In particular embodiments, the substrate is smokable, but in other embodiments may be non-smokable or comestible.
Abstract:
A flavor composition is formed by combining a first precursor composition with a second precursor composition to form a precursor flavor composition. The precursor flavor composition is then subjected to a sufficient temperature to cause one or both of the first and second precursor compositions to undergo at least a partial phase change to a gaseous material. Generally, the first and second precursor compositions are immiscible.
Abstract:
Oils or fats from plants and/or animals are chemically treated to create flavor/palatability enhancer (FPE) products for use with animal foods, such as dog or cat food. This method involves mixing triglycerides (from the oil or fat) with sulfur and/or nitrogen donor compounds, such as sodium sulfide. The mixture is cooked at a temperature close to boiling, or higher if pressure-cooking is used, for a period of time sufficient to break down large numbers of triglyceride molecules into their constituent fatty acids and other fragments. Under suitable cooking conditions, the organic fragments will react with sulfur and/or nitrogen atoms from the donor compound(s), to form relatively small organic molecules containing sulfur and/or nitrogen. These cooked products can be used as FPE's for pet foods for dry kibbles or biscuits, either alone, or mixed with a standard base compound such as a hydrolyzed liver digest. Two-bowl comparison tests indicate that these FPE's are effective, and they do not suffer from unpleasant odors that would disturb pet owners. This method can be used to process various types of fatty or oily wastes created by food-service or manufacturing operations, and because the cooking process will totally sterilize the ingredients, it can be used with contaminated, adulterated, or partially-spoiled food substances that are not adequately safe for human consumption.
