But smoothies are to be made and consumed fresh. Why would anyone make it beforehand?
Well, you are mistaken!
Here are some very valid reasons why we may need to make smoothies beforehand:
- There are times when you have work at hand and it helps to have it made beforehand so that you do not waste time trying to make it during work hours.

Things Needed to Prepare Smoothie in Advance
- Choose healthy and fresh ingredients – This is the first step as making a healthy smoothie is way better than going the other way and going close to having ingredients as fresh as possible that are packed with nutrients. This would not get any better. So, you need to select the combinations of vegetables and fruits which is appealing to you and blend a smoothie out of it.
- Mason jars or popsicle molds– When you need to store smoothies for later use, then you definitely need to freeze them. You can choose the option of mason jars and freeze the smoothie in those jars. In this way, you can use the smoothie whenever you need it. At times, try having a smoothie in popsicle molds. It is a refreshing change to have a smoothie popsicle once in a while. Another option is using containers. You can freeze the cut fruits or smoothie in it, as another to opt for, in case a mason jar or popsicle mold is unavailable.
Why is it Happening?
Certain fruits like bananas, strawberries, and apples have more sugar than others. The brown color that you see is the result of a chemical reaction between the fruit’s natural sugars and oxygen in the air, which produces an enzyme called polyphenol oxidase, or PPO for short. It’s this enzyme that causes those smoothies to turn brown.
Why does my smoothie turn green?
If you make your smoothies with leafy greens, then the chlorophyll in them can turn them green. The best way to avoid this is by adding a teaspoon of lemon juice before blending everything together. It will help break down those proteins which are causing that color change.
Why does my smoothie turn gray?
Smoothies can turn brown for many reasons.
The most common reason is oxidation due to exposure to oxygen, such as when the smoothie has been sitting out on a countertop or in a fridge too long and air hits it. Oxygen reacts with some of the natural color-giving ingredients like chlorophyll, and the result is browning.
Molecules in some smoothies are more susceptible to oxidation, such as bananas and strawberries. So if you want to prevent your smoothie from turning brown make sure not only time but also ingredients will be taken into account when making it.
How to Prevent smoothies from Turning Brown?
- Keep ingredients ready for the smoothie – The ingredients for a smoothie can be kept in one mason jar and frozen. This can be done for various smoothies at a time by keeping the respective ingredients for that respective smoothie in a jar followed by cut vegetables or cut fruits for another smoothie in another jar and so on. In case, jars are not available then go for Ziploc bags for each smoothie or container. Do make sure the jar and the containers are air-tight. So, when you prefer to have a smoothie, you can take that mason jar and just blend the ingredients.
- Another way is making a smoothie ahead and storing it in the manner suggested above and freezing it. In that manner, you can have already made a smoothie and just have it without scrambling to blend one which is as easy as possible. So blend the frozen ingredients whenever you want and freeze them. Have the smoothie as and when required. This, in a way, reduces your work and gives you time to relax.
- Ensure the containers are air-tight when freezing – This is important as you need the ingredients or the prepared smoothie to stay longer. Also, make sure you fill the jar or container up to the top so that no air gets trapped. Trapping of air can deteriorate the nutrition of the smoothie or ingredients stored and oxidizes the smoothie or ingredients which causes the smoothie or ingredients to go brown. So, choose an air-tight pack or container or a mason jar and fill it to the top and close it tightly along with sealing it. Then once you ensure there is air trapped on the top, freeze it.
For example – my favorite container is the Rubbermaid Brilliance Food Storage Container
- Addition of lemon juice – adding lemon juice to the prepared smoothie or the ingredients can help prevent it from browning. As we already know, lemon juice is vitamin C which is an added benefit. When adding lemon juice, make sure the ingredients are coated in it, and in the case of smoothie, just stir it well till it is properly mixed, and then store. This keeps your smoothie well and good. The flavoring of the lemon juice gives a great citrusy taste which will not make you feel monotonous drinking the smoothie or get bored with it.
- Don’t add berries in the smoothie until it’s time to drink – There may be browning of berry smoothies if kept for long. So you can avoid the berries or keep them ready for later. In the latter case, get your berries for that particular smoothie and freeze them in a freezer bag. You can use it whenever you want to consume the smoothie. Just add the berries from the bag, blend, and drink.
Do note that after taking your required berries for a smoothie, keep the freezer bag containing the remaining berries in the freezer for later use or use whenever you want.
How to Prevent Banana Smoothies from Turning Brown?
Banana smoothies are rich in natural sugars and iron so they likely turn brown more quickly than other fruits.
One way to prevent this is by adding a teaspoon of lemon juice before blending everything together. The acidity will help break down those proteins which are causing that color change.
You also can use the methods mentioned above which will definitely work!
What to Do if your Smoothie Turned Brown Overnight?
If your smoothie turned brown overnight, it could be because you combined the fruits with milk which will produce an enzyme that causes reactions. It also might mean you added ice to a blender and let it sit for too long before blending.
To fix this problem just add more of whatever ingredients are left over so that everything is blended together well enough to not have any ice chunks or brown pieces.
Will Banana Smoothie Keep Overnight?
If you follow the tips in this blog post, most likely not.
– The milk might curdle and ruin your smoothie – so it’s better to use water instead of milk if you want to keep the smoothie overnight.
– The bananas will go brown with time, which is natural as they are being exposed to oxygen in the air but if you want a good color when you drink it next, add some lemon juice before blending everything together and store in an airtight container.
How long can you keep a banana smoothie in the fridge?
This is a huge question. A lot of variables go into it and the answer will be different for every person. For instance, does your yogurt have any live cultures in it? If so, then you can keep that smoothie up to one day in the fridge before bacteria starts multiplying and you should throw it out.
If you have a pureed banana in your smoothie, it will last about one day in the fridge because of enzymes that start to break down proteins when exposed to oxygen. If you want to keep your bananas fresher for longer than this, then freeze them and they’ll retain their color as well as be much more resistant to browning.
Will Avocado Smoothie Turn Brown?
The color of the smoothie will turn brown if you add any fruit that contains natural pigments or vegetables with a high beta-carotene content. The only way to prevent this is by adding more fruits and veggies in order to dilute it, but then your smoothie won’t be as tasty.
Avocado smoothie is a healthy drink. People are always worried about the color of their smoothie, but most people don’t know how to keep it from turning brown.
Will avocado smoothie turn brown? A smoothie is made from water, fruit, and other ingredients. When the natural sugars in a fresh, ripe avocado are blended, chemical reactions can occur that turn it brown faster than a banana or apple juice would.
