Preservatives Overview
Natural Preservatives Defined
Natural preservatives are in many foods you eat. They come from plants or animals. People have used them for a long time. Salt, sugar, vinegar, and lemon juice are some examples. Citrus fruits like lemons and oranges have acids that stop bacteria. Honey and maple syrup keep food fresh by lowering water. Herbs and spices like rosemary, thyme, cloves, and cinnamon have oils that fight germs. Garlic helps stop bacteria, fungi, and yeast. Natural oils like olive oil and coconut oil stop food from going bad.
Tip: You can use natural preservatives at home to keep fruits, vegetables, and meats fresh for longer.
Here is a table that shows the main types of preservatives used in food:
Category | Examples |
|---|---|
Natural Preservatives | |
Artificial Preservatives | Sodium benzoate, Potassium sorbate, Calcium propionate, Sulphites |
Artificial Preservatives Defined
Artificial preservatives are made in labs. Scientists make these chemicals to keep food from spoiling. You find them in many packaged foods. Synthetic preservatives stop mold, yeast, and bacteria from growing. Potassium sorbate keeps mold away in baked goods and cheese. BHA and BHT keep fats and oils from going bad. Benzoates are in salad dressings and fruit juices. Nitrites and nitrates protect cured meats. Propionates stop mold in bread. Sulfites help keep dried fruits and wines fresh.
Artificial preservatives use chemical methods to make food last longer. For example, potassium sorbate mixes with water and makes sorbic acid, which stops spoilage. BHA and BHT help fats and oils stay fresh.
