Do microplastics end up in your food when you blend in a plastic blender?
Whether plastic blenders release microplastics into your food or drink cannot be answered with the available study. If you want to reduce the risk, you can opt for a blender with a glass or stainless-steel jar.
The only study provided (on street-vended fruit juice in Tanzania) describes how kitchen blenders are used in juice preparation. However, this study does not measure microplastics and makes no claims about whether plastic blenders release particles into food or drink.
Based on this research, nothing can therefore be said about whether blending in a plastic blender introduces microplastics into your food or drink. The question has simply not been investigated in the provided literature.
