Yes, Thai peanut sauce can go bad, but how quickly it spoils depends on several factors.
Shelf Life of Thai Peanut Sauce
- Unopened: Commercially produced Thai peanut sauce, when unopened and stored properly (cool, dark place), typically lasts for 12 to 18 months past the printed expiration date. [Source: Cooklist]
- Opened & Refrigerated: Once opened, the sauce should be refrigerated in a tightly sealed container. In the refrigerator, it will last up to one week. [Source: FoodByMaria, multiple other sources]
Factors Affecting Spoilage
Several factors influence how long your Thai peanut sauce remains safe to consume:
- Storage: Proper refrigeration is crucial. Leaving the sauce at room temperature significantly accelerates spoilage.
- Ingredients: The specific ingredients used can affect shelf life. For instance, the type of peanut butter or coconut milk used may influence its overall longevity.
- Contamination: Introducing bacteria through unclean utensils can reduce the shelf life.
Signs of Spoilage
Discard your Thai peanut sauce if you notice any of the following:
- Off-odor: A sour or rancid smell indicates spoilage.
- Mold: Visible mold growth is a clear sign of contamination.
- Changes in texture: Separation, thickening, or unusual texture changes can also indicate spoilage.
- Changes in color: Significant changes in the original color of the sauce.
Making Thai Peanut Sauce Last Longer
To maximize the shelf life of your homemade Thai peanut sauce:
- Use airtight containers: This prevents exposure to air and slows down spoilage.
- Refrigerate immediately: After opening, store it in the refrigerator as quickly as possible.
