What You Need to Know
During lacto-fermentation, lactic acid bacteria convert sugars into lactic acid, reducing pH to 3.5–4.0 and creating a hostile environment for pathogens. Vinegar pickles introduce acetic acid directly, achieving immediate preservation by setting pH below 3.5. Salt concentration and temperature modulate microbial kinetics, influencing flavor, texture, and safety.
The Science
Primary Reaction
Fermentation of sugars to lactic acid (and acetic acid in vinegar pickles) by lactic acid bacteria
