Expiration & Storage Tips
When does vinaigrette expire?
An unopened bottle of commercially prepared vinaigrette can last for up to a year past the printed date on the package if stored properly. Once you open it, you should consume it within three months to maintain the best quality, even though it's generally safe to use up to six months. Homemade vinaigrette has a shorter shelf life. It's safe to consume it for about one week if refrigerated properly. Freezing is not recommended for vinaigrette as it may alter its texture and consistency.
How do you tell if vinaigrette is bad?
Detecting a spoiled vinaigrette can be done through smell, look, and taste. If it has an off-smell or the oil has a rancid odor, it's time to toss it. Similarly, inspect the vinaigrette for color changes or mold. Lastly, if the taste is significantly different from when you first made or opened it, it's probably gone bad. Remember, it's always best to err on the side of caution when it comes to food safety.
Tips for storing vinaigrette to extend shelf life
• Always seal the container properly after use.
• Store the vinaigrette in the refrigerator, whether it's store-bought or homemade. Cold temperatures slow down the oxidation process and prevent bacteria growth.
• If made with ingredients like garlic or herbs, consumption should be faster because these items can spoil more quickly.
• In the case of homemade vinaigrette, use fresh ingredients. The better the ingredient quality, the longer the vinaigrette will last.
• Avoid introducing contaminants by not dipping used utensils into the vinaigrette bottle or jar. Always use clean utensils when serving.
