Plasmatech was a device installed on space ships which allowed periodic rotation of desired food-stuffs, based on crew selection. After accumulation of interstellar organic materials during transit, biotransformation technology was utilized for food synthesis. Apparently, there were certain "Levels" of Plasmatech, although Level 4 Plasmatech is the only known Level.[1]

The USS Sheridan was equipped with Level 4 Plasmatech.[1]
