SPECIFICATION

Features:

1. pH Regulator: Trisodium citrate dihydrate acts as a buffering agent and pH regulator in food and beverage products. It helps to stabilize the pH and prevent excessive acidity or alkalinity.
2. Emulsifier: Trisodium citrate dihydrate can function as an emulsifying agent, assisting in the formation and stabilization of emulsions between oil and water phases in food and cosmetic products.
3. Chelating Agent: Like citric acid, trisodium citrate dihydrate is a chelating agent. It can bind to metal ions, such as calcium or magnesium, preventing them from interfering with the stability and quality of certain products.
4. Preservative: Trisodium citrate dihydrate exhibits antimicrobial properties, which can help inhibit the growth of bacteria and extend the shelf life of processed foods and beverages.
5. Texture Modifier: Trisodium citrate dihydrate can enhance the texture and mouthfeel of certain food products, such as dairy desserts, by improving their emulsification and stabilizing properties.

Applications:

1. Food and Beverages: Trisodium citrate dihydrate is widely used in the food industry as an additive for its various functions. It is commonly found in dairy products (to control acidity and enhance emulsification), carbonated beverages (as a flavor enhancer and preservative), processed cheeses (for texture improvement), and jams/jellies (as a gelling agent).
2. Chemical Industry: Trisodium citrate dihydrate is used as an excipient in Chemical formulations to adjust the pH of medications, enhance stability, and improve the taste of oral solutions. It is also utilized in certain anticoagulants.
3. Cosmetics and Personal Care Products: Trisodium citrate dihydrate is employed in cosmetics and personal care products as a pH regulator, emulsifying agent, and buffering agent. It can be found in skincare products, shampoos, conditioners, and bath products.
4. Industrial Applications: Trisodium citrate dihydrate finds applications in various industrial processes, including water treatment to prevent scaling, as a component in detergents and cleaning agents, and as a buffering agent in electroplating solutions.
