Abstract:
The invention concerns a process for the preparation of flavoring components through non-enzymatic oxidative degradation at an elevated temperature below 250.degree. C. of p-hydroxy-styrene-type compounds of general formula (I), wherein R1 is hydrogen or a hydroxy or alkoxy group and R2 is an alkyl group or an organic functional group. Preferably R1 is hydrogen, hydroxy or methoxy and R2 is an alkyl group or an aldehyde or keto group, a carboxylic acid or ester group, or a carbinol, carbinol ester or an ether group. The oxidative degradation is conveniently carried out in an organic solvent at a temperature between 120 and 200.degree. C. The flavoring components are suitable for incorporation into flavoring or directly into foods. They have a phenolic and sweet-aromatic flavor character. ##STR1##
Abstract:
Flavorants are obtained by collecting differing volatile fractions evolved over differing periods of time from at least one fatty acid into which oxygen is introduced while being heated to a temperature of from 150.degree. C. to 475.degree. C.
Abstract:
A substantially oil free fried flavor food product having a fried flavor obtained by cooking a starch and/or a protein from grain flours, vegetable flours, food protein source materials and the like with fats and oils under controlled conditions for producing roux, extracting the oil from the roux resulting in a food product having a definitive fried or peak flavor as can be correlated by the color of the food product. The substantially oil free food product has enhanced fried flavor and is most suitable as an interface coating through enhanced adhesion properties for raw vegetables and consumable meats. The dry powder food product having fried flavor can be utilized in a variety of foods, either as an ingredient or coating, producing a consumable food having fried flavor without the food being fried in oil.
Abstract:
The invention concerns a process for the preparation of flavoring mixtures by heating of fatty acids or fatty acid derivatives with an oxidizing agent in the presence of at least 0.1% by weight of an antioxidant. Polyunsaturated fatty acids or animal or vegetable fats which are rich in such acids are preferred as starting materials. The preferred oxidizing agent is oxygen. The oxidation mixtures obtained are rich in aldehydes and can be used to improve the organoleptic properties of foods.
Abstract:
Flavorants are obtained by collecting at least one of differing volatile fractions evolved over differing periods of time from a liquid pool of at least one fat or one oil and mixtures thereof into which oxygen is introduced while being heated to a temperature of from 300.degree. C. to 475.degree. C.
Abstract:
Flavoring compositions are prepared by heating at least one fatty acid at a temperature of from 150.degree. C. to 475.degree. C. in the presence of oxygen.
Abstract:
A process is disclosed for obtaining a caramel butterscotch flavored aqueous phase composition comprising heating an admixture of an aqueous solution of sugar and butter in a ratio of 50:1 to 1:10 at a temperature of about 100.degree. F. to 250.degree. F. for about 0.5-5 hours. Heating is done in the presence of a base catalyst with the admixture held at a pH of at least 7. The resultant emulsion is separated to recover an aqueous phase having the caramel butterscotch flavor. When the aqueous phase is incorporated into a low calorie table syrup, the resultant product has excellent butterscotch flavor impact and the syrup maintains its clear composition.
Abstract:
A butter-like concentrate is provided, which concentrate is a mildly heated mixture of25-98% (w/w) of an oil or fat preferably containing butterfat,2-74% (w/w) of protein and carbohydrate taken together, and0-20% (w/w) conventional adjuvants.Preferably the fat contains at least 25% (w/w) butterfat and the ratio of protein to carbohydrate is between 3:1 and 1:3. The butter-like concentrate is heated mildly so that it contains 5-hydroxymethyl-furfural and maltol at levels which increase considerably upon further heating to 135.degree. C. for 10 minutes in a closed vessel.
Abstract:
FOOD FLAVORING MATERIALS ARE PREPARED BY REACTING HYDROGEN SULFIDE WITH CARBONYL COMPOUNDS IN A DIKUTE AQUEOUS MEDIUM. THE FLAVORING MATERIALS ARE STABLE IN THE AQUEOUS MEDIUM AND RETAIN THEIR HIGH POTENCY AND QUALITY WHEN COMBINED WITH AN EDIBLE FIXATION AGENT AND ARE DEHYDRATED
Abstract:
Processes for the production of alliaceous flavoring compositions comprising reacting specified mixtures of Bunte salts (S-alkyl and/or S-alkylene thiosulfates) wherein the alkyl and alkylene groups contain up to three carbon atoms, with an alkali metal sulfide at temperatures of 0* to 100* C. to obtain a mixture of dialkyl, dialkylene, or alkyl alkylene di- and trisulfides having an alliaceous flavor impression.
