What are 3 common ingredients which act as preserving agents in food?

1. Salt: Salt (sodium chloride) has been used for centuries to preserve food. It draws water out of microorganisms, inhibiting their growth and preventing spoilage. This is why salt is used in curing meats, pickling vegetables, and preserving fish.

2. Sugar: Sugar, like salt, acts as a dehydrating agent, making it difficult for microorganisms to thrive. It's commonly used in jams, jellies, and fruit preserves to inhibit mold growth and extend shelf life.

3. Vinegar (Acetic Acid): Vinegar is a natural acid that inhibits bacterial growth. It's commonly used in pickles, sauces, and marinades. The acidic environment created by vinegar slows down the spoilage process.
