Good explanation. I always enjoy watching your videos.

You should have cut it in half. Also, maybe test if the seed is still viable.

how do the results of this method compare to using a freeze dryer? Like on sliced banana or apple or other things people eat in a freeze dried form.

That is some next-level patience. Great explanation too!

Your explanations make sense but I don't really get where the pumpkin gets the energy from. The way I understand it, this process can only really work if you add heat energy to the pumpkin because if water sublimates from the pumpkin, it gets colder and as soon as the pumpkin has the same temperature as the cooling element, everything will be in equilibrium and the process stops. Maybe the fact, that the freezer temperature is not really that well regulated helps, it may even be possible to accelerate this by periodically lowering and increasing the temperature.... Anybody else got an idea where the sublimation energy is coming from?

It’s coming from the room surrounding the freezer, just ordinary heat leakage. The expansion coil is always colder than the rest of the freezer so water moves from anything inside to it.

I would assume that the flavor would be drastically impacted if the end intent was to eat it.

I always like the explanation that the temperature of an object is just an average. Individual molecules have higher or lower temperature by random chance. And sometimes a molecule near the surface has enough energy to turn into a gas and sublimate. It does happen in reverse as well which is why frost will form on things in the freezer under some conditions. Whether things freeze-dry or get covered in frost is all about the equilibrium between individual molecules randomly sublimating or depositing on the surface, so a statistical model is required.

please plant the seeds :) i wonder in 1% is still alive
