Since the very beginning, people have been captivated by the possibilities that microgravity in space holds, envisioning both the extraordinary and the restricted aspects of such an environment.
One question that could have stuck with many is: "Can we fry food in space?" Scientists, in particular, have been intrigued by the physics involved in cooking with oil in space.
Is Frying in Space Possible?
Surprisingly, recent research by the European Space Agency (ESA) has revealed that frying food in space is possible, debunking concerns that gravity might be essential for effective frying.
Frying has been a popular cooking method worldwide for centuries. It is known for quickly transferring heat, reaching 375 degrees Celsius, and creating a crispy exterior while keeping the interior moist.
However, frying involves more than just oil, heat, and food. Here on Earth, when frying food products like potatoes for French fries, bubbles form on the surface and rise due to buoyancy created by gravity.

This IFLScience report notes that in the special environment that is space, it was uncertain whether the absence of gravity would affect the formation of bubbles and hinder the frying process.
The researchers aimed to investigate this potential kitchen nightmare scenario and shed light on the complex physics and chemistry of food.
How ESA Did the Experiment
Surely, scientists cannot conduct experiments involving cooking oil and extremely high temperatures in space laboratories - it is a recipe for disaster. Here is how they did it.
A specially constructed automated fryer was used to conduct the experiment safely. The fryer, which is outfitted with high-speed cameras to track the movement of bubbles, could operate without human assistance.
The experiment was done during an ESA parabolic flight, which induces periods of weightlessness similar to microgravity.
The study measured the oil and potato temperatures and observed how the bubbles behaved.
Encouragingly, the results demonstrated that the bubbles detached easily from the surface of the potatoes, even in microgravity conditions.
In short: this means that astronauts embarking on long-duration missions, such as those to Mars, could potentially enjoy the delight of having fries in space.
More Than Just Fries in Space
However, the implications of this research extend beyond culinary indulgence. "Apart from nutrition and comfort, studying the process of frying in space could also lead to advancements in various fields, from traditional boiling to producing hydrogen from solar energy in microgravity," noted John Lioumbas, the study's lead author.
The findings of this experiment, published in the journal Food Research International, provide valuable insights into the fundamental science of cooking in space.
Professor Thodoris Karapantsios from the Aristotle University of Thessaloniki, a research team member, emphasized the complexity and fascination of the physics and chemistry behind the food. The study demonstrates how this knowledge can extend beyond cooking and impact other scientific disciplines.
While more research is necessary to refine certain parameters, this breakthrough paves the way for astronauts to enjoy a more diverse menu during their space missions.
Gone are the days of rehydrated meals as the sole option.
In related news, NASA unveiled the 11 finalists for its Deep Space Food Challenge back in February. Interestingly, most of these finalists have directed their best efforts toward developing healthy food options that can significantly extend their shelf life.
