Pickling refers to which process?

Pickling refers to which process?

• A. The process of drying foods by sun
• B. The process of preserving or extending shelf life by anaerobic fermentation in brine or immersion in vinegar
• C. The process of heating and sealing foods
• D. The process of removing moisture by sublimation

Answer: (B)

Pickling preserves food by creating an acidic, low-oxygen environment that slows spoilage. It works by two main routes: fermentation in brine, where salt encourages lactic acid bacteria to produce acids that lower pH, and immersion in vinegar that directly acidifies the food. This acidity inhibits spoilage microbes and pathogens, extending shelf life while adding flavor. Other preservation methods involve drying to remove moisture, heating and sealing as in canning, or removing moisture by sublimation (freeze-drying). Those approaches rely on different mechanisms and don’t hinge on anaerobic fermentation or acidification like pickling.
