Jimmy from sunny Palm Bay Florida mailed our webmaster the following question. What is the shelf life of fresh carrot juice? The shelf life for all fresh homemade carrot juice is roughly 48 hours if refrigerated in a sealed container or juice jar. If you plan to store your carrot juice up to the 48 hour marker, then it's a very good idea to stir into it a heaping tablespoon or two of fresh squeezed lemon or lime juice. The citric acid will not only keep the juice from oxidizing, it will also prevent any bad bacteria from growing in the juice during the short term. I do not recommend drinking carrot juice after the 48 hour period. Due to the juice's high natural sugar level it can become a breeding ground for unhealthy types of bacteria. There are however very healthy ways of extending the shelf life of the juice, but they included either freezing or canning the juice, two recipes which are available here on our website. Thank you again for the great question.
