Is it possible to cook food by freezing it? Like, get it cold enough that any bacteria dies, then defrost? You could enjoy meat like it was raw without the risk.

That fancy gastronomy bullshit uses a lot of liquid nitrogen to make shit have a break-glass effect, but that's for more ready to eat foods like desserts.
Freezing fish before serving it raw kills the tapeworm, and provided it's of a high quality, that's all you need to do before serving it. Don't quote me, but I believe most raw beef dishes like steak tartare require the beef to be brought below a certain temp to ensure safety. "cooking" through protein denaturation is a thing; acids, bases, and even alcohols can be used for this. Ramen noodles are made with lye, and ceviche is a raw seafood dish using lime juice to "cook" it.

But by definition, you can't "cook" food without heat, even if you can prepare it for consumption.

Nah man you could send your beef into the far reaches of the solar system like Pluto or something and there would probably still be dangerous bacteria still alive on it. Sorry.

No, freezing doesn't really kill bacteria apparently. It works for killing parasites in fish but the bacteria is still there. If lab-grown meat is going to be produced in sterile conditions then it should be safe to consume all of it raw as long as it was kept refrigerated and eaten soon after production.

>>	Anonymous Sun Jul 14 23:21:09 2019 No.12635962 >>12635520 Yes. A majority of fish fit for raw consumption has been flash frozen to kill potential parasites/bacteria. >>12635541 Provided the source is not infected.

Bacteria and parasites are killed by cooking because it denatures enzymes they require to survive, or outright destroys them (turns to ash). Freezing does not do this. It cannot denature or destroy many single celled organisms because they are not as susceptible to water crystalization damage.
In short, no you cannot freeze food to kill microorganisms.

>The average temperature of empty space between celestial bodies is calculated at 3 kelvins (minus 270.15 degrees Celsius or minus 457.87 degrees Fahrenheit). Absolute zero, the temperature at which absolutely all activity stops, is zero kelvins (minus 273.15 degrees Celsius or minus 459.67 degrees Fahrenheit).

The only way to lose heat in space is via radiation, so thats why humans can survive the temperature. It takes ages for your skin to freeze.
The problem for humans is pressure, you get divers sickness and die from gasses in your body phase changing.
And you die from asphyxiation after 5 mins.

Tards survive being fully frozen tho, they hibernate and water doesnt mechanically destroy their cell walls.

provided you're not shielded from sunlight and you're also alive, you'll boil before you freeze.
Your body has literally zero way to vent heat faster than the sun and your own bodily processes can give it to you.
