I add 3 scoops of casein powder to each bottle (one bag) of Soylent. Normally I make it at night and then eat it for breakfast and dinner the following day and breakfast the day after that. This gives me a total time of about 32 hours in the fridge for the last meal. However, I’ve noticed that if that is stretched out to something more like 48 hours, the taste changes and it seems to be more bitter.
I’m wondering if this is a problem (i.e. the fats went rancid or the protein spoiled) or whether it’s ok to drink but just tastes worse. I know that Soylent is ok to be kept for 48 hours, so I’m guessing it must have to do with the protein? It doesn’t smell bad, that’s the only reason I think it may just be fine. And the taste is certainly worse and is bitter, but I can still drink it and have done so a couple times without any consequences that I know of. I don’t really have time to mix individual meals separately, mixing 3 at once is one of the things I enjoy most about Soylent.
Any insight into whether this is a problem?
