10 Nov 2022 --- Researchers from Macquarie University, Sydney, Australia, are looking into ways of creating a nutritious food system with three components: a 3D printer, yeast and science. Their vision, published in Nature Communications, focuses on nutrition for space travelers through the innovation of meals with the same texture, taste and nutrients as those produced on Earth. By using modified yeast cells, scientists believe that 3D-food printing technology can be used to customize nutritious and environmentally sustainable meals for astronauts.
