Trisodium Citrate

Trisodium citrate is the sodium salt of citric acid. It is chiefly used as a food additive, usually for flavor or as a preservative. As a conjugate base of a weak acid, it can perform as a buffering agent or acidity regulator, resisting changes in pH.Trisodium citrate is used to control acidity in some substances, such as gelatin desserts. It can be found in the mini milk containers used with coffee machines. It is used as an anticoagulant in blood transfusions. It is also used to relieve discomfort in urinary tract infections, such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative.

sodium erythorbate

Sodium Erythorbate is a kind of antioxidant, which acts as preservatives by inhibiting the effects of oxygen on food, and is beneficial to human health.


It has been confirmed as a statutory food additive by FAO and WHO. Taking starch as its main ingredient, it is produced by the fermentation of microorganism. Sodium Erythorbate could keep food color and natural flavor, and prolong the shelf time, without any side effects. It is widely used in the production of foods, such as meat products, beer, beverages, canned fruits and vegetables, confiture, frozen fish and so on.
