At the International Space Station, chocolate biscuits were baked in December, which is the first case of weightless food baking. According to the results of the experiment, preparing such a meal on long space expeditions will take much longer than on Earth.
Microgravity has an impact on many processes that, as a result, flow in it differently than on Earth. For example on crystal growth, cell action and - baking. While on the ground, the convection of air in the oven significantly helps in translating the heat into the food, but in the zero-gravity universe there is no classical convection. The Zero G Kitchen is surrounded food around and around with heating elements, much like a toaster. The device flew to ISS last November with funding for the DoubleTree hotel chain and NanoRacks, an example of a recent space station commercialization where privateers can rent astronauts' time.
