What is pH regulator？
[Close]
pH regulator is a food additive added to maintain the pH level of food in a suitable range so as to prevent deterioration of food quality or food color or to enhance the effect of other food additives. By adding pH regulator, food is maintained under slightly acidic conditions within the pH level of four to five, to prevent the decay of food by suppressing bacteria proliferation for extending a shelf-life of food.
