Sure will. If you seal it and put it in a bowl of ice it will be even better.


This. Fillets/loins/steaks will last much longer in ice. Just be sure to seal or put the fillets in bags to keep the ice from ruining the meat.

You could put saltwater in a bowl, put lkots of ice in the bowl, blot the tuna with a paper towel then seal it in a ziplock and submerge in the sub 32 degree water in the fridge for probably 10 days, but you are better off just eating it within 7. the drier you keep it in the bag, the longer it will keep without discoloring.

know you think I'm messing with you because it's you, but this is entirely too long for tuna. I deal with a lot of tuna. On ice, it will not last more than a week, even in the bottom of the fridge.


It really depends on how it is stored. If it was whole tuna (H&G - headless and gutted so ice could go in head/gut cavity) kept in a vat of ice, it can easily last 2.5+ weeks. The color and freshness will suffer but it will still be good to eat.

Now fillets/loins, do not last as long as whole gutted and iced fish. I find the color changes on fillets (bloodline/flesh) much quicker once filleted/loined. I'm sure bacteria breaks the meat down quicker once filleted also.

that's been my experience. A loin will not safely last 2 weeks in a fridge.

Is there an acid constituent in poke that effects the tuna?
Nope. A little sea salt to start it out for about an hour. Then it gets dressed (my way anyway) with garlic chili paste, soy, sesame oil, scallions, Ogo (pickled red seaweed) and some masago. Heaven on earth.

I made some last night that I should have taken a picture of.

Mildly. It's function in poke is nothing like the function of lime juice in ceviche.

We vacuumed sealed the portions we did not eat in the first three days and froze it. Would I have been better off just icing it in the fridge for the next weekend? Does freezing in vacuumed sealed bags have a negative?

I would say yes, but would like to see what Jason has to say.

Maybe you should get a better fridge because it has lasted in mine and about ten minutes ago I seared two thick steaks off it and we had lunch. I believe I can tell when something is bad.

Try oil poaching it. Everyone seems stuck on seared or grilled...but oil poaching makes it velvety and delicious.

Oh damn. I get it fresh from time to time and this is next. Make small batches, or will it sit up in the fridge?

I'll eat it three days after I've made it but that's about as far as I go. I take a yearly 7-day long range trip and catch enough to last all year. I get it processed into 1.5lb packs so I only really make small batches.

I was given some tuna that was caught this weekend. How long can I keep it in the fridge without freezing


Probably already too long. You should just give it to me and I'll feed it to the neighborhood stray cats. I promise.

What would you say the negative is? Not disagreeing. Just wondering your opinion.

Commercially, all tuna is vacuum packed. All over the world it is done the same. They do have a frozen nitrogen process that is better but it is very expensive. Requires a restaurant to have a special freezer that gets way colder than a regular freezer.

If it is in the fridge, I would say keep it wrapped in paper towels and vacuum sealed or wrapped in at least 3 layers of saran wrap. Keep it on ice and change daily. Change the paper every day or every other day. I have had good success with just keeping the tuna on ice in an ice chest for a week, wrapped up of course.

Thanks everyone. I just decided to eat it again last night. Which leads me to another question regarding mercury levels in tuna. Is this an issue and how much can you eat safely? Thanks,

I hope not. But pregnant women should probably be careful.

I am probably pulling this out of my arse, but I thought I read somewhere that by freezing a protein it disrupts the cell wall and therefore changes the texture? Is frozen and thawed tuna good, hell yes, I eat it all the time, but is it as god as fresh? Also I would think that the commercial flash freezers are able to preserve things much better than my frigidaire .
