Ketchup Expiration Dates

Let’s squeeze out the truth about expiration dates on ketchup bottles. In reality, they play a vital role in indicating when the quality and safety of ketchup are at their peak. But did you know there’s a difference between “best-by” and “use-bydates?

  • Best-by: This date signifies the peak freshness and quality of the ketchup. However, it’s not a hard and fast deadline. You can still consume ketchup beyond this date, though its taste, color, and consistency might not be as great.
  • Use-by: This date is more of a safety guideline. It tells you when the manufacturer recommends using the ketchup before its quality deteriorates.

Now, you might wonder what determines these dates. Here’s where the magic happens! Factors such as ingredients, preservatives, and packaging help establish the shelf life of our beloved condiment.

Shelf Life of Ketchup

So, how long does ketchup last? The answer to this thrilling question depends on whether the ketchup is unopened or opened.

But wait, there’s more! Several factors can impact the shelf life of ketchup, including storage conditions, temperature, exposure to light, and air. That’s why some ketchups can last longer or shorter than others.
