Effect of steviosides and system composition on stability and antimicrobial action of sorbates in acidified model aqueous systems

The effect of steviosides on sorbate stability and on its antimicrobial action was studied in aqueous systems (pH 3.0). The use of steviosides decreased sorbate destruction in all the systems. Its effect on nonenzymatic browning (NEB) depended on the system composition. From the point of view of mic...
