Dressings used for stuffing or as side dishes have expiration dates. This is because the ingredients are usually perishable and used for dressings. Moisture can cause bacteria to grow, so cleanliness is essential. Also, exposure to air can change the mixture over time.

3. Microbial Growth

Even when dressings are stored correctly, they can still be prone to contamination by germs. This issue can occur, especially if they’re prepared or handled in unsanitary conditions. These bad germs can multiply and ruin the dressing.

4. Oxidation

Oxidation is a natural process. Fats and oils in dressings react with oxygen, causing rancidity. This results in an unpleasant taste and smell. To prevent oxidation, store dressings in airtight containers and use fresh ingredients.

5. Temperature Matters

Temperature plays a crucial role in dressing longevity. If dressings are not stored at the right temperatures, particularly if left at room temperature for extended periods, it can accelerate the growth of bacteria, hastening spoilage. Proper preservation can assist in extending their freshness.
