Description
Oil preserves vegetables by forming a physical barrier that excludes oxygen, while herbs provide phenolic antimicrobial compounds.
Technical
The anaerobic environment created by the oil layer suppresses aerobic spoilage bacteria. Phenolic compounds such as carvacrol and thymol from oregano, thyme, and bay leaf lower pH and directly inhibit pathogens like *Listeria* and *E. coli*. The combination of oxygen exclusion and chemical hurdles ensures long‑term safety and flavor.
