Is Canned Tuna Gluten free: An overview

Tuna is basically a saltwater fish. Most of the canned Tuna that your kitchen probably has come down to you from the Pacific. Long journey, huh?

Fresh Tuna is honestly rare to find. Hence, most people do not have a choice other than canned fish. However, the canned version of Tuna is also quite fascinating. 

After catching fresh Tuna from the ocean, the fish are stored in cold storage. Following that, they are thawed. The pre-cooking phase starts here, and afterward, the fish’s skin is stripped away. This thing can save the canned fish from unwanted oil. Then the meat is deboned and sorted into light meat and red meat categories. 

Lighter meat is ideal for canning. The loins or the edible parts of the fish are cleaned before going into the canning procedure. 

Following the cleaning stage, the fish meat is stuffed in cans alongside stock, oil, or water, and some of the time preparing, like salt. The jars get tops and are vacuum fixed to forestall spillage and tainting.

The cans are then washed prior to being cooked and sanitized at high temperatures that should reach 240 degrees to guarantee the absence of live microbes inside the fixed holders. Of specific concern are spore-shaping anaerobic microorganisms, like Clostridium botulinum.

The cans are cooled, named, and checked for quality confirmation. This interaction includes evaluating harm to the jars, including imprints, enlarging, and failing seals, which could point to contamination. Canned Tuna is then delivered to distribution centers and conveyed to stores around the United States to stay on racks for 2–5 years.

Nutrition value of tuna


Canned Tuna tastes fantastic, and all of us know that. And probably there’s no debate about it. But apart from that, canned tuna is nutritious as well. It comes to us with a lot of minerals and vitamins. However, the fresh tuna fish contains more of it. 

Canned Tuna is considered to be a fantastic food for new moms and pregnant women. It contains iodine in it which helps in lactation. 

It also provides us with Omega 3, especially the DHA and EPA. Both of these are best friends for our brain and heart. Also, our eye health is ensured by it. 

However, there’s one specific point that you should be concerned about. The amount mercury present in canned or fresh tuna can be brought to a question. Excessive mercury consumption is not at all suitable for health. 

That said, one might avoid this problem if small fish are consumed. And canned Tuna is derived explicitly from smaller ones. Hence this issue is not much troublesome if canned one is consumed.
