Sodium Citrate E331, Food Additives Sodium Citrate Description
Sodium citrate is colorless or white crystal and crystalline powder. It is inodorous and taste salt, cool. It will loss crystal water at 150° C and decompose at more high temperature. It dissolves in ethanol.
Sodium Citrate E331, Food Additives Sodium Citrate Application
Sodium citrate is used to enhance flavor and maintain stability of active ingredients in food and beverage in detergent industry, it can replace Sodium tripolyphosphate as a kind of safe detergent it can aloe be used in fermentation, injection, photography and metal plating.
Sodium citrate is sometimes used as an acidity regulator in drinks, and also as anemulsifier for oils when making cheese. It allows the cheeses to melt without becoming greasy.
