コハク酸ナトリウム

Origin

Sodium succinate is the sodium salt of succinic acid. Succinic acid is a naturally occurring dicarboxylic acid found in plant and animal tissues. It is also produced during the metabolic breakdown of glucose and other nutrients. Industrially, sodium succinate can be produced by the neutralization of succinic acid with sodium hydroxide or sodium carbonate. Succinic acid itself can be derived from petroleum-based sources or through fermentation processes using microorganisms.

Usage

Sodium succinate is used in the food industry as a flavour enhancer, buffering agent, and pH regulator. It can contribute a slightly salty and umami taste to foods. It is often found in processed foods, soups, sauces, seasonings, and meat products. As a buffering agent, it helps to maintain a stable pH, preventing undesirable changes in acidity during processing and storage. It can also be used in pharmaceutical formulations and as a chemical intermediate in various industrial processes.

Side Effects

Sodium succinate is generally considered safe for consumption at levels typically used in food. Succinates are natural components of the human metabolism. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has not established a numerical Acceptable Daily Intake (ADI) for succinic acid and its salts, indicating its low toxicity. However, as with any food additive, excessive consumption may lead to mild gastrointestinal discomfort in sensitive individuals. No significant adverse effects have been reported in the scientific literature at normal usage levels. People with specific sensitivities to sodium should be mindful of their overall sodium intake.

Regulatory Status

Sodium succinate is approved for use as a food additive in many countries, including those following European Union regulations. It is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) under specific conditions of use. Its use is regulated to ensure that it is used at levels that are safe and effective for its intended purpose.
