E500ii - Natriumhydrogencarbonat

Origin

Sodium hydrogen carbonate, also known as sodium bicarbonate or baking soda, is an inorganic salt composed of sodium cations and bicarbonate anions. It is naturally occurring as the mineral nahcolite and is produced synthetically on a large scale.

Usage

Sodium hydrogen carbonate has numerous applications in the food industry. It is primarily used as a leavening agent in baked goods, where it reacts with acidic components to release carbon dioxide, causing the dough to rise. It is also used as an acidity regulator, buffering agent, and to control pH in various food products. Specific applications include its use in baking powder, self-rising flour, and as an ingredient in beverages to create effervescence. Furthermore, it can be used to tenderize vegetables during cooking and to neutralize excess acidity in certain recipes. It is also used in some processed foods as a component of various formulations.

Side Effects

Sodium hydrogen carbonate is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. Excessive consumption can lead to metabolic alkalosis, characterized by elevated blood pH, which can cause symptoms such as muscle weakness, spasms, and irregular heartbeat. Individuals with sodium-restricted diets should be mindful of their intake, as sodium bicarbonate contributes to overall sodium consumption. There is no established ADI (Acceptable Daily Intake) for sodium bicarbonate, as it is considered safe at levels typically consumed in food. However, excessive intake should be avoided, particularly by individuals with underlying health conditions such as kidney or heart problems.

Regulatory Status

Sodium hydrogen carbonate 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 as E500ii. Regulatory bodies such as the EFSA (European Food Safety Authority) and the FDA (U.S. Food and Drug Administration) have evaluated its safety for use in food. It is generally recognized as safe when used in accordance with good manufacturing practices and at levels consistent with its intended function.
