Tuna or canned fish process

When it comes to working with canned tuna or fish and determining how to heat it up without compromising flavor, you need to know what you’re working with.

For example, is the tuna or fish pre-cooked when it is canned? How might the canning process affect your cooking process when you use these products in your recipes?

Tuna and most canned fish are cooked before being canned. This means you could eat it straight out of the can without cooking it if you wanted to.

This is the process that canned tuna goes through before being canned.

Canned tuna is cooked long before it is canned. Some will say it’s overcooked because it’s overcooked.

Why is it cooked like this? Because the goal is to eliminate microorganisms that could cause bacteria and unwanted side effects. 

1. Tuna and other canned fish start out fresh at some point . The fish is caught by some type of fishing boat and delivered to canneries for further processing. Most of the time, the fishing boats freeze the tuna to keep it until it is delivered to the cannery.
2. The frozen tuna is then unloaded in the cannery and is also cold stored there until further processing. 
3. Tuna are graded by size and weight to keep similar fish together. This helps processing as there are specific rules and guidelines to follow. The classification by sizes and weights allows to obtain the best final results.
4. Before the tuna is prepared for canning, it is inspected for quality. In addition, many canneries also inspect the vessel the tuna was delivered on to determine that things were done correctly prior to delivery as well.
5. The tuna are then thawed in large tanks of water before being sent off for cleaning.
6. Before cleaning, the fish is steamed to remove excess fat and make it easier to clean.  The fish is then cooled and cleaned, separating the meat from the skin and bones.
7. Often the meat is boiled to kill microorganisms.  However, some companies do not boil it, since they pre-bake it. This allows the tuna to taste fresher at the end.
8. The tuna is then separated into cans and the cans filled with tuna go through the process of salting and adding broth, water or oil to the can.  The can is then vacuum sealed and passed through a water bath process for final sealing and sterilization.

After the canning process is complete, most tuna companies have quality control representatives who take samples from each batch the next day to ensure proper odor, texture, flavor, and cleanliness to determine whether the lot meets the standards.

Heat tuna and other canned fish

There is no exact science to heating canned tuna and other fish, but there are a few things to keep in mind. There are several tips and recommendations to ensure the best heating experience.

Since canned tuna is already cooked, you must be careful to heat it gently when you heat it for use out of the can.

If you’re not careful, you risk ruining the texture and flavor, which is what you’re probably trying to avoid by turning to this guide.

Risks of heating canned tuna or fish

The risks of heating canned tuna or fish do not lie in the safety of the food. Heating canned tuna does not cause health problems.

Tuna or any other canned fish has gone through specific sterilization processes to reduce any chance of bacteria in the canning process.

The only risk you should be concerned about would be if the contents of the can were left out in the open for some time and had a chance to cultivate or grow bacteria. This is an ultimate risk with any food left out in the open: canned, cooked, raw, or otherwise.

So what are the risks of heating canned tuna and other fish? Ultimately, the risks trace back to the quality of the food when heating it from the can. Remember that the canned product has already been cooked once.

These are some of the risks to be aware of:

• If it is not heated correctly, you can suffer from excessive cooking of tuna and other fish
• The heating process must be done carefully so as not to ruin the taste.
• If you heat in the microwave, use a low power
• Cooking time may vary, but it is important not to overcook or overcook
• The canned fish is already cooked. You are simply reheating the tuna - remember that
• Never boil tuna or other canned fish.  It has already been boiled once.
• Stir-frying canned tuna or fish is not recommended , as it can taste charred or overdone.

Canned tuna was designed to be used raw from the can for any purpose. This does not mean that it cannot be heated.

The key point to remember is that you are only reheating the canned tuna or fish and not cooking it. 

Canned tuna can be served cold, at room temperature, or it can be mixed into a warming dish to cook it. Each of these options is suitable and will work well for your tuna heating needs.

How to heat tuna and other types of canned fish

Are you ready for this? It’s super simple. If you are going to heat your canned fish or tuna just to eat it hot, you can heat it in the microwave, on the stove, or simply on your plate.

Here are some more detailed steps for each of those categories. 

1. Microwave - If you have a microwave, you can easily heat the tuna in it. In fact, this is the recommended heating method, unless you are adding the tuna to a hot dish that requires baking or cooking with the tuna on the plate. Microwaving tuna doesn’t take long, as you’re just heating it up. Place the tuna on a microwave-safe plate and cover with a paper towel.  In this way, the natural moisture of the canned tuna (or other fish) is preserved. Heat for just 30 seconds each time, stirring after 30 seconds and testing for heat.
2. On the Stove – If you just want to quickly heat up your tuna on the stove, it’s pretty easy. If you have used canned tuna that is in olive oil, it is best to heat on the stove. If you are heating canned tuna that is not in olive oil, add a couple of drops of oil to the pan to prevent it from drying out. You can season the tuna however you like. Just lightly sauté it over low heat until hot. You can also make a stir-fry and add vegetables or other ingredients if you feel like it. This is a great way to mix up your tuna and turn it into something delicious.
3. Heating as part of a dish - Finally, you can heat the tuna as part of another dish. If you are going to use the tuna in a hot dish, simply use the canned tuna as part of your recipe and it will heat up on its own as you cook.

For example, in a tuna casserole, you would add the canned tuna with the other ingredients in the casserole, and then proceed to bake the dish. This is just an example, but it would work like this in all cases.

Although our instructions mainly focus on the process for tuna, you can also use these same tips and guidelines when working with any type of canned fish. Follow the tips to make sure your canned tuna or fish still tastes delicious when you’re done.
