What is the additive E280?
E280 is the food additive Propionic Acid CAS 79-09-4. Propionic acid e280 is a naturally occurring organic substance. It is a transparent liquid with a pungent odor. Its main function is as an antibacterial preservative, inhibiting the growth of mold and bacteria, and it is sometimes used as a flavoring agent. Its chemical formula is CH₃CH₂COOH.
What is Propionic Acid E280 used for?
As a common food additive, CAS 79-09-4 propionic acid (E280) is widely used in various foods. It prevents baked goods such as bread slices, rye bread, and pastries from molding. In the dairy industry, it is used in certain cheeses and dairy products. E280 is also found in fermented fish and traditionally fermented foods.
How Propionic Acid works as a Preservative?
Propionic acid's mechanism of preservation is similar with that of benzoic acid and sorbic acid. The optimal pH range for its antimicrobial effectiveness is from 2.5 to 5.5.
It is the undissociated form of propionic acid that has antimicrobial activity. The undissociated propionic acid penetrates into the microbial cell membrane and enters into cytoplasm.
And then, it accumulates and dissociates prone which decreases the internal pH of the microbial and finally prevents the growth of the microbial or even kills them.
