... and after 24hrs?

As it happens, I’ve been running this experiment this weekend. I mixed up some Huel on Saturday morning and I had some yesterday and some more today (Monday morning). It had seperated a little, but a short shake rectified that. Taste-wise there was no change that I noticed. This means, that 48 hours is fine.
