Sodium Citrate (Trisodium Citrate) Chemical Formula
Description
Sodium Citrate is mainly used as an expectorant and a urine alkanizer. It is also used as a pharmaceutical aid and as a food additive in Dairy Industries which cater in Cheese Manufacturing and Beverages. It is also a water treatment chemical and as a Laboratory Reagent.
Applications and Effects
Our product helps in the storage of all the Dairy products especially cheese. It can prevent the dairy products from getting stale for 90 days than compared to other solutions. If it is used in water then can prevent the growth of bacteria for 15 days.
