Liquid nitrogen ?

I have access to liquid nitrogen supercooling and I was wondering if any of you have experimented with this for bait preservation.

I am thinking mainly of Mackerel, where I culd take the fillets off, cut into usable strips and then feeze them in liquid nitrogen.

This should mean that when the baits are defrosted they maintain a much firmer flesh than if you slow freeze them in a domestic freezer.

Anyone played around with this at all ?

I figured I'd ask before goofing around with something that could make my fingers drop off...

:rolleyes:
 
It would work mate, the reason bait turns mushy when frozen in a domestic freezer is all due to ice particle size. The quicker it freezes the smaller the particles. This method would mainly benift peeler crab, and all soft baits really. Most bait companies blast freeze their mackerel (Dragon baits i think do) and you can tell the difference. Aslong as it hasnt been defrosted and refrozen.

I've made ice cream with liquid nitrogen. Nicest ice cream ive ever made. So smooth, its the perfect family amazment moment. As you can make ice cream before their eyes! :)

But i do belive you need a licence to handle liquid nitrogen? Or am i mistaken? If not fancy getting me some ;) ?
 
Yeah sounds like a good idea but you would need quite a bit of liquid nitrogen to immerse several mackies and the boil off would be quite spectacular :) If you know what you are doing and can be safe (cryo gloves, safety glasses, heavy clothing) then give it a go. I once immersed a cactus in liquid nitrogen and left it a few minutes to freeze then put it back on the windowsill. People walking past looked in amazement as the cactus smoked away in the sunlight. It disintegrated when it thawed out into a pile of mush. Great fun :D
 
Don't know how many litres the dewar holds, but it's external dimensions are about the size of a small car...

:D

So, a lot, I'm guessing. Enough to do some baits now and then anyhow :p

Don't think you need a license mate but if out happens the company would need to proove that adequate training had been given, nowt worse than a cryogenic burn apparently.
 
Yeah, ive heard some nasty stories about it. I had to learn how to handle it before i went near it. Seen what it did to a rose during the demonstration. Never in my life have i smashed a rose into peices, untill that day :)
 
Why stop at N2, get yourself some liquid He, bit more expensive and you might lose your fingers, but hey if gets your bait flash frozen!!!

Only joking mate! Stay safe, should work a treat if done properly!!

dont see why it wont work . thats how there freeze prawns in factory's. ever wonder how there not frozen in a block wen you get them from Iceland exct .there put them in a tube and blast them with nitrogen as the tube is shaken.

Small splashes sting a bit but it isn’t too bad as the nitrogen boils turning to gas that gives some insulation between you and the liquid.

Very true mate but if you get a glug of it yer in big trouble. Very painful burn and severe scaring and it's even worse when there's no pain, that means that the flesh has been totalled and the only remedy is surgical removal:o

Forgot to add that the gas is also an asphyxiant, two lung fulls and yer brown bread.

a used 2 work in a chemical plant, what your talking about is not nice stuff, be very careful m8. alreet 4 the locks on bank safe`s though. !
 
forgot to mention side fillets do freeze quicker in the freezer waste time hoying full mackerel in takes a lot longer probs why they go mushy when defrosted :(
 
All joking aside, this facility is in a bioengineering lab with fully shielded 'hands off' access.

I wouldn't consider it if there was a risk involved for the sake of a few baits
