“I bought a $20 blender from Target and began blending green smoothies. I really enjoy them but I am wondering how do I reduce the foam (bubbles) that forms on top? I’m not sure if the reason I get the foam is because it is a cheaper blender, fruit/veggie choice, or something else. I can easily pour or scoop the foam out but wanted to know if there was a way to prevent this?” – Jazmine
Jazmine, I’m afraid your foamy green smoothies might be caused by your $20 blender. It sounds like what is happening is that your blender is somehow sucking air into your smoothie and these air bubbles are causing the foam to appear.
Another possible cause might be that you have too much liquid in your blender and it’s whipping the ingredients with the air in the pitcher to make a frothy drink.
What I would do is this:
In your next smoothie, be sure to use a good base fruit like banana or mango. Add no more than 4-6 ounces of water (if using two bananas) and steer clear of watery fruit like citrus, watermelon and grapes. If your smoothie turns out frothy, it’s probably your blender design.
If your smoothie comes out normal, then you were probably adding too much liquid.
My only concern about using a blender that makes foamy smoothies that are filled with air bubbles is that you are oxidizing your fruit and greens during the blending cycle. Of course, oxidation is inevitable when you chop fruit and even chew it, but a blender that sucks too much air into the pitcher to create bubbles is, in my view, over-oxidizing the food. This can lead to a slight decrease in nutrient content, but I wouldn’t say it’s detrimental to your health.
If you can swing it, I highly recommend getting a high-end blender, especially if you are committed to making green smoothies a daily part of your life. Even though they are a bit pricy, they are worth it and then some.
I use the Vitamix and it’s my main kitchen appliance.
