Thoughts on flash freezing DIY food?

[ichthyogeek]

I've been tossing this idea around in my head, but if you're really doing your best to shred large seafood (bivalves, shrimps, fish fillets, etc.) into bite sized pieces for your fish, and then freezing the product, why not just go the whole mile and buy dry ice to flash freeze the food again?


This video gives a pretty good lay explanation on flash freezing. Of interest to me, is the ice nucleation bits. It might or might not still be applicable if you're making fish goop (pulverizing everything then binding it with gelatin), vs. shredding the food into bite sized pieces...

Interesting.

I collect small shrimp in an estuary and put the shrimp in a Ziplock baggie and just freeze it. Then pull it out and just cut/saw off some slices and put it in the mix of food I'm preparing for the tank.

I’ve thought about doing this. Im guessing it would work with liquid nitrogen as well?

I would think that liquid nitrogen would be the best and fastest method, as long as you have access to it anyway.

I’m willing to assume liquid nitrogen would be best because it’s colder, but dry ice might be more practicable since it’s easier to access. Unless Amazon has started selling liquid nitrogen?

Should work well

You can get bottles of liquid nitrogen at any welding supply store that sells gasses.
