Afficher plus [+] Moins [-]anglais. The reduction in the salt content of foods without affecting their production methods and sensorial properties is a current challenge for the food industry. In foods, sodium ions can adopt various motional states through interactions with macromolecules such as hydrocolloids or exchange between two phases in heterogeneous systems. A correlation between sodium ion mobility and the saltiness perception has been suggested, the role of sodium ions with restricted motion or "bound" sodium being of particular consideration. There is therefore a need to investigate the mobility states of the different pools of sodium ions and to quantify these fractions to develop a better understanding of their respective roles on salt perception. In this context, as it is one of the most salted foodstuffs and as it is consumed worlwide, cheese is a target of choice for investigations on reducing sodium content...
