E507 - Salzsäure

Origin

Hydrochloric acid (HCl) is a strong, corrosive mineral acid. In the food industry, it's typically produced synthetically by dissolving hydrogen chloride gas in water. The hydrogen chloride gas is often a byproduct of industrial chemical processes. It is a naturally occurring substance found in gastric acid in the stomach of mammals, where it aids in digestion.

Usage

In food processing, hydrochloric acid serves multiple purposes. It's used as an acidity regulator, helping to control the pH of food products. It can be used in the production of hydrolyzed vegetable protein (HVP), corn syrups, and various other food ingredients. It is also used in the refining of sugar and in the brewing industry to adjust the pH of the mash. Furthermore, it can be used as a cleaning agent for food processing equipment. The concentration used in food is carefully controlled to ensure safety and efficacy.

Side Effects

Hydrochloric acid is a strong acid and can be corrosive in concentrated form. However, when used in food processing at appropriate concentrations, it is generally considered safe. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 'not limited', meaning that at the levels used in food, it does not pose a health risk. Direct contact with concentrated hydrochloric acid can cause burns and irritation, but this is not a concern when it is used as a food additive under controlled conditions. There are no known significant side effects associated with the consumption of foods containing hydrochloric acid at the levels typically used.

Regulatory Status

Hydrochloric acid (E507) is permitted for use as a food additive in many countries, including those in the European Union and the United States. Its use is regulated to ensure that it is used safely and effectively. Regulations specify the maximum levels that can be used in different food products. In the EU, it is listed as an acidity regulator. In the US, it is Generally Recognized As Safe (GRAS) when used in accordance with good manufacturing practices.
