NASA has granted 125.000$ to a company that is developing food printers. They use powders for carbohydrates and proteins, mix water and oil in to produce a variety of foods. Because everything is dry the powdershave a shelf life of 30 years. That is why NASA is interested. Dry food with long shelf life will enable long duration flights and low food weight with recycled water.
Among the easiest to print would be pizza, they claim, using among others powdered tomato.
