What is Lactic Acid (E270)?
Lactic Acid (E270) is a naturally occurring organic α-hydroxy acid (AHA) with the chemical formula C₃H₆O₃. It is widely used as a food additive, acidity regulator, preservative, and flavor enhancer.
Lactic acid is typically produced by fermenting renewable carbohydrate sources such as glucose, sucrose, corn starch, or sugarcane, making it a sustainable and biodegradable ingredient.
Thanks to its mild acidic taste and strong antimicrobial properties, Lactic Acid E270 is one of the most widely used acids in the food, pharmaceutical, cosmetic, and chemical industries.

Structure & Isomer Information
Lactic acid is a chiral molecule and exists in two optical isomers:
L(+)-Lactic Acid (S-form)
D(−)-Lactic Acid (R-form)
A mixture of both forms is known as DL-Lactic Acid.
It is classified as an α-hydroxy acid (AHA) because it contains a hydroxyl group adjacent to the carboxyl group, enhancing its reactivity and functionality across multiple applications.
