With regards to the blending, what is more detrimental to the Vitamin C, HEAT or OXYGEN.
I ask this because I just did a test with my blender and at 950ml it creates a massive vortex sucking massive amounts of air into the mixture. I have nitrogen and CO2 so I was thinking of filling the blender with either before I fill it and turn it on. I also have a small cooling coil that I use for other purposes that sits perfectly inside the blender to keep the heat down.
Any input here welcome.
