The story of fermented vinegar powder begins with a natural “experiment” driven by microorganisms. Using non-GMO corn and rice as raw materials, selected acetic acid bacteria and lactic acid bacteria break down sugars and produce acetic acid, lactic acid, succinic acid, and other organic acids.
These organic acids play a dual role in food preservation:
- Environment adjustment: by lowering pH, they make survival harder for acid-sensitive microbes such as Staphylococcus aureus and E. coli.
- Cell penetration: undissociated organic acid molecules can enter microbial cells, disrupt internal pH balance, and halt metabolism.
Importantly, different organic acids can work in
synergy: acetic acid is strong against Gram-positive bacteria, while lactic acid can be more effective against Gram-negative bacteria. Together, they can deliver broader antimicrobial coverage than a single synthetic preservative.
