It would be interesting to make the best of both worlds. Buy frozen or dry foods in bulk, process them into a smooth, freeze dry it and reduce it to powder. Seal that in a moisture tight package and it should have a substantial shelf life and be easily reconstituted. | It would be interesting to make the best of both worlds.

Freeze drying is the challenge. Temperature is easy, basically anything below freezing is ok. But the pressure needs to be below -0.006 atm. Actually, the temperature should be kept very close to 32F, colder temperatures makes sublimation more difficult. | Freeze drying is the challenge.

Stephen made an interesting point about soylent, it's highly processed, and we keep discovering new aspects to vegetables that make them healthy.
It would be interesting to make the best of both worlds. Buy frozen or dry foods in bulk, process them into a smooth, freeze dry it and reduce it to powder. Seal that in a moisture tight package and it should have a substantial shelf life and be easily reconstituted.
