Description
Osmotic dehydration via salt creates crisp texture while encouraging selective lactobacillus growth.
Technical
NaCl disrupts microbial competition, allowing halotolerant Lactobacillus species (L. brevis, L. plantarum) to metabolize sugars into lactic acid (C₃H₆O₃) at 2-5% salinity, lowering pH to 4.5-5.2.
Culinary Significance
Preserves vegetable crunch without vinegar's sharpness, creating umami-rich glutamate accumulation.
