First Space-Baked Cookies Took 2 Hours In Experimental Oven (go.com) 93

pgmrdlm shares a report from ABC News: The results are finally in for the first chocolate chip cookie bake-off in space. While looking more or less normal, the best cookies required two hours of baking time last month up at the International Space Station. It takes far less time on Earth, under 20 minutes. And how do they taste? No one knows. Still sealed in individual baking pouches and packed in their spaceflight container, the cookies remain frozen in a Houston-area lab after splashing down two weeks ago in a SpaceX capsule. They were the first food baked in space from raw ingredients.

Italian astronaut Luca Parmitano was the master baker in December, radioing down a description as he baked them one by one in the prototype Zero G Oven. The first cookie -- in the oven for 25 minutes at 300 degrees Fahrenheit (149 degrees Celsius) -- ended up seriously under-baked. He more than doubled the baking time for the next two, and the results were still so-so. The fourth cookie stayed in the oven for two hours, and finally success. Parmitano cranked the oven up to its maximum 325 degrees F (163 degrees C) for the fifth cookie and baked it for 130 minutes. He reported more success. As for aroma, the astronauts could smell the cookies when they removed them from the oven, except for the first.

    Chocolate chip cookies need 350 degrees f for 10-12 minutes. Baking at 300 for 20 changes how they come out.

    You have to cook the interior of the cookie no wonder why they were coming in under baked.

        I'm willing to bet that there was a uniform air temperature throughout the oven, especially after 2 hours.

        Since convection is not possible or difficult in zero gravity, heating is accomplished through electric heating elements (similar to that found in a toaster oven), powered by electricity drawn from the International Space Station’s internal power system. Heating elements are placed such that a sufficient pocket of heat is created around the food sample.

          The raw cookie dough will continuously absorb a humongous amount of energy turning water into water vapor. Only when most of the water is gone will the cookie heat up significantly.

          Since there's no convection, the oven is depending on infrared emissions and the thermal conductivity of air to heat up the cookie. The first of which is very limited at 325 degrees, and the second of which has always been very low. Just think of a winter jacket. All that's doing is putting a bunch of unmoving air between you and

          • The heating elements will not be anywhere near 325 degrees. 1600 F is the likely approximate temperature, the elements will be glowing red, and that heats the oven interior to 325 given time.

            Many earth-bound ovens have a "broil" element located above the food. It's not going to be heating the food by rising hot air.

      Generally, you don't want burning hot stuff in a space station. That it reaches temperatures sufficient to bake anything in a way that is considered safe is impressive by itself.

      And that oven doesn't work like anything we have on earth. Because there is no gravity, there is no natural convection. They could have used a fan, if hot stuff is bad, what about spinning hot stuff that blows hot air and cookie crumbs? So no fan. They designed their oven so that there is a static pocket of hot air in the middle, wh

      Here's the caveat, this baking is done at 1 atmosphere and 1 "g" (in theory) with an average temperature of 20 C/70 F. Even while at high altitudes, there are different baking instructions so the same is not hard to factor when thinking on a space station.

    TFA says a difference in baking time was to be expected, but they were not expecting it to be so *big*, and that degree of variance is certainly not a result I'd have even considered if posed this as theoretical exercise. Clearly we've just discoverd that there's a lot more to baking than just heat, so what difference might microgravity be making that causes such an extended baking time? Ingredients not able to mix properly in low G? Everything being "on the float" while in the oven causing issues with thermal transference within the cookie?

    Or maybe it's just the use of the individual sachets - the hot air isn't in direct contact with the actual ingredients, so the heat must be transferred throughthe sachet to the ingredients rather than just convection to the exposed surface of the cookie? That seems most plausible to me, and is probably linked to why fan ovens need less baking time than convention ones at the same temperature, so maybe they could start there.
    • Convection probably doesn't work properly, so heat has to propagate strictly by warming the air nearest the heating element? We'd have to know the design of the oven, but if it doesn’t have a fan to circulate the air, I’m sure it takes much longer to get the whole system up to temperature.

      • by Zocalo ( 252965 )
        TFA does mention issues with convection in microgravity, so you would indeed need a fan. Not sure whether or not the oven has one though as they seem to have taken more "surround the food with radiators" approach, which they liken to a toaster. That combined with the use of the sachets makes me think no fan is likely, but it's not specifically ruled out by the article.

        I'm still going with convection (or lack thereof) being the main cause of the difference. (And to address the air pressure issue mention

    • Also, what is the atmosphere like in the ISS? It is Sea-Level pressure, or is it like a mountaintop in there? Altitude and the corresponding air pressure there makes a difference in the time it takes for an egg to boil, so that may be a big factor.

    • Heat rises and those temperatures are already on the low side for baking, presumably constrained for fire safety reasons.

      • When there is no gravity, what direction is âoerisesâ?

        1). The temperature was not high enough to induce the chemical reaction to âoebakeâ the sugars in the batter in the same time as on earth. What microreaction in the semiliquid batter is influenced by gravity?

        2). Heat transfer through the baked portion to the interior batter is apparently worse in space.

        3). The air flow was limited due to lack of forced convection (no fan), and we learn natural convection isnâ(TM)t so great in sp

      > Or maybe it's just the use of the individual sachets

      That and 300*F. The Maillard Reaction is necessary for baking cookies and that starts about 360*F external temperature. Most ovens set for 350 have surges above that so we use 350 as a standard temp for baking the plurality of foods.

      The pouches also prevent evaporation, unless they were exotic material. Imagine if on earth you put dough in pouches in 360*F steam - that's not going to make a crisp cookie. If it's not crisp it's not really cookie. Technically I think they made bad muffins.

      I wonder if they had any food scientists involved or just mechanical engineers. They can't have tasted like cookies on Earth.

      Try a 350*F hot plate with a slow revolution to create some gravity for them to spread.

    • Too bad they didn't actually measure the temperature inside the cookie. So much bickering could have been avoided.

    From the "Space oven" info - it relies on infrared radiation to heat the cookies, similar to toasters. Using a toaster to bake a cookie is not a good idea - it will scorch the outermost layer, leaving the inside unbaked. An oven similar to the popular air fryers will work much better, but it will open another can of worms - you have to firmly secure the cookies in place and filter the air from small particles. An air fryer with a centrifuge and an air filter around it may do the job. After opening the air filter should continue to suck air.
    • by GeLeTo ( 527660 )
      ... actually forget the centrifuge, the hot air current should be enough to secure the cookies and small particles to the bottom. The air is filtered, reheated and blown from above.

      So... It was a big Easy Bake oven? Maybe they needed a higher wattage bulb.
    • It's essentially a toaster, so instead of cranking up the heat to (deliberately) burn the sides of the toast, it's got a lower temperature to allow the heat to move through the food - a bit like sous vide, but in air instead of water.

      It does seem rather mean to send a batch of cookies/biscuits/biscotti up there, make them cook them and then send them home again *without leaving them at least one*!! I'm sure it's because they're expensive, and because they want to science out of them, but really, how much mo

  • No surprise there. 150 degrees C is too low. 180 would be better.

    • I suspect they went on the conservative side of things to avoid having to dump waste heat in space station, which is a non-trivial problem if you get carried away baking.

      If you can keep most of it contained by taking it up in the phase changes, you've got less to worry about beyond the inevitable losses.
