Smoothies make for a delicious and nutritious snack or light meal. With the right ingredients, they can be packed with fiber, protein, vitamins and minerals. Many smoothie recipes call for fruits like bananas, which provide potassium, vitamin B6 and vitamin C. However, bananas and other fresh ingredients can spoil quickly at room temperature. This leads to the common question – can you store a banana smoothie in the fridge?
Can banana smoothies be refrigerated?
Yes, you can keep a banana smoothie refrigerated. The cold temperature of the refrigerator will help prevent spoilage and extend the shelf life of your smoothie. This gives you more flexibility when preparing smoothies in advance or having leftovers.
When kept chilled in the fridge, a banana smoothie will usually stay fresh for up to 3 days. Just make sure to store it in an airtight container to minimize exposure to air and prevent the smoothie from absorbing fridge odors.
Tips for storing banana smoothies in the fridge
Here are some tips for storing your banana smoothie properly in the refrigerator:
Use an airtight container
Pour your smoothie into an airtight container, jar or bottle with a tight-fitting lid before refrigerating. This prevents oxidation and keeps outside flavors or odors from seeping in.
Fill container to the top
Leave as little air space as possible in the container – fill it to the very top with smoothie before sealing. The less air inside, the better.
Let it chill completely
Pop the sealed container straight into the fridge – don’t leave it out on the counter. Let the smoothie chill for at least 2-3 hours before drinking for best texture and flavor.
Don’t freeze
While you can freeze smoothies for longer storage, refrigerating is better for smoothies you plan to drink within 3 days. Freezing may compromise the texture.
Use within 3 days
For maximum freshness and nutritional value, aim to drink your refrigerated banana smoothie within 3 days. Discard any leftovers after 3 days.
Does chilling change the taste?
Storing a smoothie in the refrigerator won’t significantly change the flavor, though it may dull the taste slightly. Bananas in particular can take on a more starchy or mealy texture when chilled.
Here are some tips to help a refrigerated smoothie retain the best flavor:
- Add a squeeze of lemon or lime juice to brighten up the flavors.
- Stir in a pinch of cinnamon or vanilla extract before serving for a flavor boost.
- Add a handful of fresh ice cubes to chilled smoothies right before blending again.
- Let the smoothie sit at room temperature for 10-15 minutes before drinking to take the chill off.
How to tell if a refrigerated banana smoothie has spoiled
Banana smoothies stored properly in the refrigerator should keep for 2-3 days. However, there are some signs that indicate your smoothie may have spoiled:
- Change in color – Fresh smoothies are vivid in color. Discoloration to brown, gray or green can indicate spoilage.
- Separation – Separation of ingredients with clear liquid pooling on top.
- Off smells – An unpleasant sour, rotten or yeasty smell.
- Visible mold – The presence of fuzzy mold spots or webbing in the smoothie.
- Off tastes – Dramatically unpleasant flavors like bitter, sour or rotten when you take a taste test.
If you notice any of these warning signs, it’s best to discard the smoothie. Consuming spoiled smoothies can potentially cause food poisoning.
How to store banana smoothie ingredients
To make smoothies that last, you’ll need to store the ingredients properly too. Here are some tips:
Bananas
- Store unripe bananas out on the counter, then move to fridge once ripe.
- Leave bananas in their peel until you are ready to use them.
- Once peeled, soak bananas in lemon or pineapple juice to prevent browning until ready to use.
Leafy greens
- Rinse and dry greens, then store loosely wrapped in paper towels in an airtight bag.
- Do not seal greens when still wet – this promotes spoilage.
- Place greens in the crisper drawer of your fridge.
Fresh berries
- Check berries and discard any spoiled, moldy or damaged ones before storing.
- Put unwashed berries in a single layer on a paper towel lined container or baking sheet.
- Cover loosely and refrigerate for up to 3-4 days.
Yogurt, milk, juice
- Always refrigerate dairy products like yogurt, milk and kefir.
- Store juices and milks in tightly sealed containers.
- Check use by dates and use within 3-5 days of opening.
Chopped fruits/veg
- Prep smoothie ingredients like chopped fruit and vegetables in advance.
- Spread ingredients out on a sheet pan or plate lined with paper towels.
- Cover loosely and refrigerate for a day or two until ready to blend.
Should you add liquid to a refrigerated smoothie?
Refrigeration can thicken up blended smoothies – especially those made with frozen ingredients. If your smoothie seems too thick, you can thin it out before drinking by:
- Adding a splash of milk or juice
- Adding water or ice cubes
- Microwaving briefly to soften – about 20 seconds
Avoid over-diluting with too much liquid. Just add small amounts at a time until you achieve the desired consistency.
Benefits of making smoothies in advance
Preparing banana smoothies in advance and storing them in the fridge offers several advantages:
Saves time
Making a batch of smoothies ahead lets you grab and go for breakfast or a snack without having to blend every time.
Helps use ripe produce
Fridge storage gives you more flexibility with ripeness. You can prep smoothies with ripe bananas and berries before they spoil.
Makes morning routines easier
For busy mornings, having pre-portioned smoothies ready to grab simplifies breakfast.
Allows ingredient pre-prep
Wash and chop ingredients when you have time, then refrigerate until ready to blend.
Avoids waste
Blending a batch lets you use up ingredients while fresh, reducing food waste.
Top tips for smoothie meal prep
Here are some final tips for safely preparing several days’ worth of smoothies in advance:
- Wash and prep produce as needed, then store pre-portioned servings in airtight containers in the fridge.
- Wait to add wet or perishable ingredients like dairy, yogurt and leafy greens until ready to blend.
- Assemble full smoothies in individual serving jars or containers with lids.
- Label each container with the contents and date prepared.
- Refrigerate immediately after making and consume within 3 days.
- Give bottles a good shake or stir before drinking to recombine any separation.
- Add ice or liquid to adjust thickness as needed.
