Description
Mustard oil creates an anaerobic environment that selects for beneficial LAB while inhibiting pathogens.
Technical
Allyl isothiocyanate from mustard oil suppresses Gram-negative bacteria while allowing Lactobacillus species to thrive. The β-sitosterol in mustard oil stabilizes cell membranes during fermentation.
Culinary Significance
Essential for creating shelf-stable achar pickles without refrigeration, with oil acting as both preservative and flavor carrier.
