E335ii - Tartrate disodique

Origin

Disodium tartrate is the disodium salt of tartaric acid, a naturally occurring organic acid found in many plants, particularly grapes. It is produced commercially as a byproduct of winemaking, specifically from the tartrate-containing lees and argols that precipitate during fermentation. The tartaric acid is then neutralized with sodium hydroxide or sodium carbonate to form disodium tartrate.

Usage

Disodium tartrate is primarily used as an acidity regulator, antioxidant, and sequestrant in the food industry. It helps to control the pH of food products, preventing spoilage and maintaining desired texture and flavor. It can also act as an antioxidant, preventing oxidation and discoloration in certain foods. As a sequestrant, it binds to metal ions, preventing them from reacting with other components in the food and causing undesirable changes. It is found in a variety of products, including baked goods, processed fruits and vegetables, jams, jellies, and beverages. It is also used in some pharmaceutical applications.

Side Effects

Disodium tartrate is generally considered safe for consumption at levels typically used in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has not established a numerical Acceptable Daily Intake (ADI) for tartaric acid and its salts, including disodium tartrate, indicating a low level of concern regarding its toxicity. However, excessive consumption of tartrates may have a laxative effect in some individuals. Individuals with kidney problems should exercise caution, as tartrates are primarily excreted through the kidneys. Allergic reactions are rare but possible.

Regulatory Status

Disodium tartrate is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. In the EU, it is designated with the E number E335ii. The FDA considers it Generally Recognized as Safe (GRAS) when used in accordance with good manufacturing practices. Regulations specify the permissible levels of disodium tartrate in various food products.
