How long can you keep a banana smoothie in the fridge?

A freshly prepared banana smoothie can be kept for up to 2 days in the fridge. For prolonged storage, consider refrigerating your banana smoothie in either blended or ready-to-blend-pack form. 

The frozen banana smoothie will last 3 months in the freezer if stored correctly. Never refreeze a thawed banana smoothie. 

Smoothies with frozen ingredients

Smoothies that contain frozen ingredients in their recipe will last a little bit longer than those with fresh fruits. This is because freezing is a preservation technique that prolongs the shelf life of the product.

Keeping such a smoothie in the fridge will also result in a change in consistency and flavor as the frozen ingredients melt. So if you don’t have a problem with that, you are free to store them in the refrigerator.

Smoothies with bananas and other fruits

Now, this is where it can get tricky. As for homemade smoothies, you already know which fruit you used and how old was that fruit. Unfortunately, you can not tell if the store-bought fresh fruit smoothies did actually contain “Fresh” fruits in them. 

If you’re thinking about putting such a smoothie in the fridge, you can not be sure that it will last for 2 days. This is where you need to know the signs of spoilage so you do not fall victim to their cheap selling tactics. 

Most fruit juices are prone to oxidation, so when you make them a part of your smoothie, you need to be cautious about the oxidation process. Storing these smoothies in an airtight container is the best practice to stop the oxidation process. 

You might have seen bananas and apples going dark in color when exposed to environmental air. This is due to the oxidation process that you need to stop when you store your smoothie in the fridge.
