In an experiment the first of its kind, astronauts baked chocolate cakes.

Pioneers baked cakes in special conditions in an unattractive oven at the International Space Station last month.

Three pieces of baked goods, especially wrapped, were sent to Earth aboard the SpaceX Dragon spacecraft.

The experiment aims to study cooking options for future space trips.

And revealed the results of the experiment carried out by astronauts Luca Parmitano and Christina Koch this week.

What is the taste of baked goods? The answer is unknown until now.

A spokesman for the "Double Tree" company, which supplied the pioneers with the dough, told "BBC" that the cakes will be subject to additional examination by food experts to assess the final result of the operation.

It will be known from the results of the checks whether the baked goods are suitable for consumption.

Five pieces of cake were baked over a few days to reach the appropriate temperature and time for baking.

On Earth, it takes twenty minutes to bake cakes at a temperature of 150 degrees Celsius, but astronauts have concluded that the process takes much longer in space.

The first cake that was baked for 25 minutes was immature, but the second, which baked for 75 minutes, smelled cakes freshly baked in the atmosphere of the vehicle.

And it turned out that the fourth and fifth cakes were the best (the first was baked for 20 minutes and left to cool for 25 minutes, while the second baked for 130 minutes, and left to cool for 10 minutes).

While the buns were baking, Parmitano, an Italian astronaut from the European Space Agency, was watching the process.

Astronaut Koch posted a tweet on social networking site "Twitter" that she sent from space saying, "We baked cakes and prepared milk for Santa Claus this year. Happy holidays to everyone from the space station."

And bake cakes in a special oven designed specifically to work in the Space Center and transport the oven and cakes making supplies on board a special vehicle that left Virginia last November.

The company that designed the oven describes its shape as a "cylindrical, insulated packaging, specially designed to be suitable for baking inside in conditions of gravity in the center of space."

Food is heated in the oven with electrical heating elements similar to those used in a toaster, the company said.

"While we have reports of the smell and appearance of astronauts on the space station, we are eager to examine the results of the baking process," said Mary Murphy, of the NanoRax shipping company.

Double Tree stated that it plans to display the baked goods for visitors to watch and gain information about the experience.

The results will help experts in their future efforts to make long-haul space flights more pleasant, the company said. (BBC)
