DESCRIPTION:
Sodium tartrate (Na2C4H4O6) is a salt used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings.
As a food additive, Sodium tartrate is known by the E number E335.
Because its crystal structure captures a very precise amount of water, Sodium tartrate is also a common primary standard for Karl Fischer titration, a common technique to assay water content

Sodium tartrate is a disodium salt of l-( + )-tartaric acid that is identified by transparent, colorless, and odorless crystals.
Sodium tartrate is obtained as a byproduct of wine manufacturing.
Sodium tartrate is generally recognized as safe (GRAS) as a direct human food ingredient.
Sodium tartrate acts as an emulsifier and pH control agent in food products.
Sodium tartrate is commonly used as an emulsifier in cheese/cheese spread products and is not to exceed 4% concentration, according to Health Canada regulations.
Sodium Tartrate is a pH-Regulating agent with antioxidant activity.
Sodium Tartrate is particularly effective retarding hydrolysis while heating at high temperatures, resulting in increase of acid values (AVs) of vegetable oils.
Disodium 2,3-dihydroxybutanedioate belongs to the class of organic compounds known as beta hydroxy acids and derivatives.
Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom.
Based on a literature review very few articles have been published on disodium 2,3-dihydroxybutanedioate.
