Hello - I am a newcomer to Soylent. I have a batch of 1.4 that expires 03/2016. I noticed that the cup I poured this AM (and mixed this AM) formed some green dots after I let it settle for a bit between sips. Is that normal? I’ve been paranoid about it being rancid but the optimistic part of me figures it’s the oil settling. Is this a common appearance of Soylent or should I be worried? Is there any visual signs of it being rancid or is smell the best way to detect that?
