Sodium acetate (trihydrate) is widely used as a shelf-life extending agent, pH regulator, etc. as it has properties to solve in water well.
What is Sodium acetate (trihydrate) （CH3COONa･3H2O）？
Acetic acid has been said to prevent bacteria cultivation
and therefore has been used not only to add sour taste but to preserve food.
Sodium acetate is a food additive obtained by neutralization of acetic acid. When used as a food additive, sodium acetate can be indicated by its group name, substance name or abbreviated name according to the purpose of use.
|Purpose||Group name or abbreviated name|
|Keep the pH level of food in the appropriate level||pH regulator|
|Improve taste by adding or enhancing sour taste||Sour agent|
|Improve taste by adding or controlling taste||Seasoning (organic acid)|
|Other purposes (shelf-life extension, combined use with preservative, etc.)||Sodium Acetate|
What is pH regulator？
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.
