Abstract: The present invention in a first aspect relates to taste improvement of foodstuffs, beverages, pharmaceutics, tobacco products and oral care products, using a substance according to formula (I), or edible salts thereof: formula (I): R1—CR2(OR3)—CO—X. It was found that substances represented by formula (I) are capable of modifying and complementing, the sensory impact of taste imparting substances. Thus, the present taste improving substances are advantageously applied in flavour compositions, foodstuffs, pharmaceuticals, tobacco products and oral care products. Typical examples of taste improving substances according to the present invention include N-lactoyl GMP, N-lactoyl AMP, N-lactoyl CMP, N-lactoyl IMP, N-gluconyl GMP, N-gluconyl AMP, N-gluconyl CMP, N-gluconyl IMP, O-lactoyl-GMP, O-lactoyl AMP, O-lactoyl CMP, O-lactoyl IMP, O-gluconyl GMP, N-gluconyl AMP, O-gluconyl CMP and O-gluconyl IMP and the mixtures thereof.

Abstract: The present invention in a first aspect relates to taste improvement of foodstuffs, beverages, pharmaceutics, tobacco products and oral care products, using extremely small amounts of a substance according to formula (I), or edible salts thereof: R1—CR2(OR3)—CO—X (I). It was found that at very low concentrations, substances represented by formula (I) are capable of modifying and complementing, the sensory impact of taste imparting substances. Thus, the present taste improving substances are advantageously applied in flavour compositions, foodstuffs, pharmaceutics, tobacco products and oral care products. Typical examples of taste improving substances according to the present invention include N-lactoyl GMP, N-lactoyl AMP, N-lactoyl CMP, N-lactoyl IMP, N-gluconyl GMP, N-gluconyl AMP, N-gluconyl CMP, N-gluconyl IMP, O-lactoyl-GMP, O-lactoyl AMP, O-lactoyl CMP, O-lactoyl IMP, O-gluconyl GMP, O-gluconyl AMP, O-gluconyl CMP and O-gluconyl IMP and mixtures thereof.

Abstract: NEW MATERIAL: A compound of formula I (R is 1˜6C alkyl other than ethyl, 2˜6C alkenyl). EXAMPLE: 2-Methyl 2-mercaptopropionate. USE: A durable flavor and taste imparting agent usable for foods, drinks, cosmetics, healthy and hygienic use, medicines, etc. PROCESS: A 2-mercaptopropionic acid of formula II (R? is H, 1˜6C alkyl or 2˜6C alkenyl) is esterified with an aliphatic alcohol of the formula R?(OH) in the presence of a catalyst, e.g. an inorganic acid such as sulfuric acid or organic acid such as acetic acid, in an azeotropic solvent, e.g. benzene, at 60˜100° C. to give the compound of formula I easily in high purity and yield. The molar amount of the aliphatic alcohol to be used is 1˜20 times, preferably 2˜5 times, that of the compound of formula II. The amount of the catalyst to be used is 0.1˜10 wt % based on the compound of formula II.

Abstract: A process for flavouring foodstuffs includes incorporating therein a flavoring effective amount of at least one compound represented by R1-S-R2 wherein R1 and R2 represent (a) a hydrogen atom and a 1-(1-methoxycarbonyl)ethyl group or represent (b) a hydrogen atom and a 1-(1-propyloxycarbonyl)ethyl group. Foodstuffs and concentrates containing at least one of the R1-S-R2 compounds are provided.

Abstract: The present invention in a first aspect relates to taste improvement of foodstuffs, beverages, pharmaceutics and oral care products, using a compound according to formula (I), or edible salts thereof: R1—CR2(OR3)—CO—X ??(I). It was found that compounds represented by formula (I) are capable of modifying, especially enhancing, the sensory impact of taste imparting substances. Thus, the present taste modifying compounds are advantageously applied in flavour compositions, foodstuffs and oral care products. Typical examples of flavour modifying compounds according to the present invention include N-lactoyl guano sine monophosphate (GMP), N-lactoyl adenosine monophosphate (AMP), N-lactoyl cytosine monophosphate (CMP), N-lactoyl inosine monophosphate (IMP), N-gluconyl GMP, N-gluconyl AMP, N-gluconyl CMP and N-gluconyl IMP.
