E640ii - Sodiumglycinate

Origin

Sodium glycinate is the sodium salt of glycine, an amino acid naturally occurring in the human body and many foods. It is produced by reacting glycine with a sodium base, such as sodium hydroxide or sodium carbonate. Glycine itself is found in protein-rich foods and is a key component of collagen.

Usage

Sodium glycinate is used in the food industry as a flavor enhancer, buffering agent, and stabilizer. It can modify the taste of food, often imparting a slightly sweet or umami flavor. It is also used to improve the texture and stability of certain food products. Specific applications include its use in processed meats, sauces, soups, and beverages. It can also be found in some dietary supplements and pharmaceutical products. It is also used as a metal complexing agent.

Side Effects

Glycine, and by extension sodium glycinate, is generally recognized as safe (GRAS) by regulatory bodies like the FDA. No significant adverse effects have been reported with its use in food at typical concentrations. High doses of glycine (much higher than those found in food) have been associated with mild gastrointestinal discomfort in some individuals. However, such effects are rare with normal food consumption. There is no established ADI (Acceptable Daily Intake) for glycine or sodium glycinate, reflecting its low toxicity.

Regulatory Status

Sodium glycinate is approved for use as a food additive in many countries, including the United States and the European Union. In the EU, it is designated as E640. Regulatory bodies like the EFSA (European Food Safety Authority) have evaluated the safety of glycine and its salts and have found them safe for use in food at current levels.
