Origin
Salt acid naturally occurs in the human organism in gastric juice and is essential for digestion, as it can break down proteins and starches and thus make them digestible. E 507 is an inorganic mineral acid whose salts include sodium chloride - that is, table salt. Salt acid is a pungently smelling liquid and is produced for industrial production from concentrated sulfuric acid and table salt. Actually, the salt acid is an aqueous solution of hydrogen chloride gas.
Usage
E 507 can be used without maximum quantity restrictions in all food products. E 507 is mainly used for water treatment or production of bottled water. Additionally, it is used in the manufacture of spices. Similarly, E 507 is used to obtain glucose syrup and maltodextrin from corn starch.
Risks
In its capacity as a food additive, E 507 is considered harmless for the human organism. Therefore, an ADI value (Acceptable Daily Intake) has not been set so far. However, through E 507 as a technical auxiliary substance, reaction products are formed that can be contained in the food and may not be harmless.
