A flavour composition comprising a compound of formula (I) and edible salts thereof, wherein R.sub.1 is an alkyl residue containing 2 to 18 carbon atoms, or an alkene residue containing from 9 to 25 carbon atoms with 1 to 6 double bonds, R.sub.1 together with the carbonyl group to which it is attached is a residue of a carboxylic acid.

The present invention relates to a method for releasing an unsaturated aldehyde or ketone represented by the general formula (2) by irradiating the compound represented by the general formula (1) with light, in which the compound represented by the general formula (1) is used as a flavor or fragrance precursor: ##STR00001##

The present disclosure discloses a production method of normal-temperature instant cooked rice and belongs to the technical field of food processing. The method of the present disclosure comprises the main steps of rice washing and soaking, flavor blending, sub-packaging, cooking, sterile vacuum sealing, cooling and crystallization and normal-temperature storage, wherein an aqueous solution containing flavor substances is adopted to perform flavor blending, and a fast cooling mode is adopted to perform cooling and crystallization. The normal-temperature instant cooked rice obtained through the production method provided in the present disclosure can keep the original flavor after being stored for 90 days.

A flavour composition comprising a compound of formula (I) and edible salts thereof, wherein R.sub.1 is an alkyl residue containing 2 to 18 carbon atoms, or an alkene residue containing from 9 to 25 carbon atoms with 1 to 6 double bonds, R.sub.1 together with the carbonyl group to which it is attached is a residue of a carboxylic acid.

A method of improving flavor of a combination of a composition for increasing circulating ketone levels is disclosed. A composition containing (D)-?-hydroxybutyric acid (D-BHB), (D)-?-hydroxyvaleric acid (D-BHV), and (D)-1,3 butanediol (D-1,3BD) is disclosed. Exemplary compositions may be incorporated into food, supplement, and beverage products.

The present disclosure provides a novel sweetener composition of improved taste of the sweetener (e.g., reduced bitterness and/or astringency, and improved overall sweet quality of the composition); food and beverage products containing the same; and methods of making the same.

Provided are a sweetness and/or saltiness enhancing agent and a method for enhancing sweetness and/or saltiness. This sweetness and/or saltiness enhancing agent includes, as an active ingredient, an oxidized oil or fat that has a peroxide value of 15 to 180 and contains 10 to 100 mass % of milk fat. This method for enhancing sweetness and/or saltiness of a food product is characterized by adding to a food product an oxidized oil or fat that has a peroxide value of 15 to 180 and contains 10 to 100 mass % of milk fat.

The present invention relates to a method for releasing an unsaturated aldehyde or ketone represented by the general formula (2) by irradiating the compound represented by the general formula (1) with light, in which the compound represented by the general formula (1) is used as a flavor or fragrance precursor:

##STR00001##

Described is a flavor-imparting agent, based on oils and/or fats, with an improved flavor, particularly a sweet scent and/or milky scent presented by lactones having 6 to 14 carbon atoms. The flavor-imparting agent with a sweet scent and/or milky scent is obtained by producing a specified quantity of lactones having 6 to 14 carbon atoms through oxidizing and heating glycerides, having specific constituent fatty acids, at 140? C. or above.
