Can you cryovac prawns?

I have cryovaced green prawns , but had to wrap them in thick hand paper and put them in Waeco freezer.
Did them in small batches for individual meals.

If you have a freezer available just put the prawns in thick plastic bags, and freeze at home first, before transferring to travelling freezer.

as long as you do it humanely......but seriously cannot see a problem. The reasons cyrovac works for meat must work for fish.

On topic, I was once told by a friend he used to dip fillets in a home brew beer sterilizer before freezing. Good theory cos bacteria continues to grow in the freezer which why they recommend eat before three months is up.

I cryovac cooked prawns every year wrap them in one of the wife's tea towels to prevent them piercing the bag then cryovac. We put them in freezer and pull them out about two weeks later with no problem.

Carlin, some of those who have responded assume you have a freezer while travelling. If that is true, you have no problem, but I suspect you have asked as you don't have a freezer.

This site:Packaging of Sea Food

has much too much info to digest, but I did find that in their 'rules', any fresh seafood to be cryovaced for sale, must be packed with 5 days of catch and the use by date must be not more than 10 days after the packing date.

The site also noted that many home refrigerators run at temperatures well above the recommended level, so their recommendations take that into account.

IF you can buy prawns that are nice and fresh (couple of days old) and your camp fridge maintains a temp below 4 degrees C, I think you should be OK for a couple of weeks.

I am always suspicious of keeping seafood. We all know that it goes 'off' faster than many other foods.

We carry a lot of vacuum packed foods when we travel. We also keep some fish and vacuum pack while camped. But I always freeze seafood and have never tried to keep it fresh, even vac packed, for more than a few days. No reason for this, other than my suspicion of keeping seafood.

In your case, what I would do is cook the prawns first. Possibly shell them (or at least remove heads). Vac pack and put them in the bottom of the fridge (coldest part). I reckon this will be fine for 10 or 12 days if your fridge works well.

Have a good trip.
