I've checked my copy of MT: Starship Operator's Manual Vol. 1 and here is what was found:
Hull and Environment p. 28
Food/Fluids: Most starships incorporate at least a token galley for food storage and preparation. Here, a variety of food preserved foods is available from a computer controlled kitchen. Most meals are stored in a condensed state until selected by a crewman or passenger.
Waste/Recycle pp. 28 - 29: In large scale systems, these by-products can even be used to fabricate additional food stores when they are mixed in proper combinations and supplemented with various nutritional additives. p. 29
