Protein resequencer

From Memory Alpha, the free Star Trek reference.

Protein resequencers aboard 22nd century starships had limited capabilties compared to the food synthesizer or replicators in later centuries. As the name implies, this device transforms bulk protein matter into a variety of foods ranging from potatoes to ice cream. The quality of the food it prepares is debatable, but crewmembers appear to be able to taste the difference from the "real thing". As a supplement to the ship's galley it can lengthen supplies a great deal on long missions. (ENT: "Fight or Flight", "Oasis")
