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: R&#x2014;CR(OR)&#x2014;CO&#x2014;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.

Taste improving substances
