E507 – Hydrochloric Acid
AcidulantDescription
Clear, colorless or slightly yellow, corrosive liquid
Notes
Hydrochloric acid is a clear, colorless liquid that's made by dissolving hydrogen chloride gas in water. In industrial food production, it's manufactured by combining hydrogen gas with chlorine gas under controlled conditions. While this might sound intimidating, hydrochloric acid is actually the same acid that your stomach naturally produces to help digest food – though the food-grade version used in manufacturing is much more diluted than the strong laboratory type. In food production, hydrochloric acid works as an acidity regulator, helping to adjust and control the pH levels of various products. It's commonly used in the processing of corn syrups, gelatin production, and in refining various food ingredients. You won't typically see it listed on consumer food labels because it's usually neutralized during processing, but it plays an important behind-the-scenes role in creating many everyday foods. This is a synthetic compound, though it's identical to what your body produces naturally. Since it's typically neutralized during food processing (meaning it reacts with other ingredients and becomes something else), it doesn't pose dietary restrictions for vegetarians, vegans, or religious dietary laws. Food manufacturers must follow strict safety protocols when handling it due to its corrosive nature, but by the time it reaches consumers in finished products, it has been safely processed and regulated.
