(This sounds like an aggressive quibble, but it isn't. I am just interested.)

May I ask: how do you know soylent is shelf stable? Is it packed in a protective atmosphere? What testing have they done?

[ChuckMcM]

The current Soylent packaging comes with a one year shelf expiration date. I don't know the testing they have done to back that up. The USCG rations have a 10 year expiration date but other stuff in my earthquake kit is best rotated/replaced on an annual basis so it works for me.

It's dry, and the packages are sealed.

For comparison, an unopened and properly sealed tub of protein powder lasts well over two years.
