    Question

    Why can packaged pickles be stored for longer durations?

    A Harmful microorganisms cannot enter the pickle jar. Correct Answer Incorrect Answer
    B High salt concentration prevents the growth of microorganisms Correct Answer Incorrect Answer
    C Beneficial microorganisms can easily grow in pickles. Correct Answer Incorrect Answer
    D Oil and salt help prevent spoilage. Correct Answer Incorrect Answer

    Solution

    Sol. Packaged pickles have high salt content, which prevents the growth of microorganisms by reducing water availability. Microbes need moisture to thrive, and salt absorbs water through osmosis, dehydrating and killing them. Information Booster:

    • Salt acts as a natural preservative.
    • Oil creates a barrier to oxygen, slowing oxidation.
    • Acids in pickles inhibit bacterial growth.
    • Airtight jars minimize contact with air.
    • Proper storage in clean, dry jars enhances preservation.
    ---:
    • (a): Microorganisms can enter but fail to grow.
    • (c): Beneficial microbes are not typically present in packaged pickles.
    • (d): Oil and salt work together, but salt is the primary agent.
