I didn't want to say anything but since you opened it up,
I have absolutely not doubt that there is a massive amount of air
in the blender and that the oxidizing action is going on like crazy.
There can be no living enzymes after being in a blender.
Still, Of a choice between a blender smoothie and a Milkshake
from a restaurant, I think that nutritionally the smoothie wins
hands down. Any blender drink probably.
