Sodium Citrate Supplier

Sodium Citrate Chemical Formula

Description

Sodium Citrate primarily functions as an expectorant and urine alkalizer. It is additionally employed as a pharmaceutical aid and a food additive within Dairy Industries involved in Cheese Manufacturing and Beverages production. Furthermore, it serves as a water treatment agent and a Laboratory Reagent.

Applications and Effects

Our solution aids in the preservation of various dairy products, particularly cheese. It effectively extends the shelf life of dairy items, preventing them from becoming stale for a duration of 90 days, surpassing the efficacy of alternative methods. When applied in water, it inhibits bacterial growth for up to 15 days, contributing to improved product safety and longevity.
