The present invention relates to a use of a dipeptide comprising proline and alanine as salty taste enhancer in an edible article comprising salt, to an edible composition comprising the dipeptide proline-alanine, and to the edible article that comprises it. In addition, the invention also relates to a method for enhancing salty taste and reducing content of salt in food and beverages.

Sweetener and flavor compositions with improved taste profiles are disclosed. Also disclosed are methods of making and methods of using such sweetener and flavor compositions.

A method for making a taste modifying ingredient is provided. The method includes a) subjecting a rice protein to enzymatic hydrolysis to obtain a reaction mixture; b) separating the reaction mixture to obtain a supernatant; and c) recovering the supernatant of the reaction mixture.
