"Hunting tuna to prevent burns" is actually rhabdomyolysis caused by the crazy struggle of tuna. Tuna acidification refers to the process from raw tuna to mature tuna. By acidification, the stiff reaction of tuna after death can be alleviated, and the fish can be changed back to soft taste. This is because once the fish reaches the stage of rigor mortis, it is no longer delicious, and it bites very rough.

Acid-discharged meat, also known as chilled meat, is a post-ripening technology advocated by modern meat hygiene and nutrition. Fresh meat has different edible values in different periods after a series of chemical and biochemical changes such as stiffness, maturity and corruption.

Tuna:

Tuna is tapered at both ends, with a moderate mouth and well-developed teeth. The branchial membrane is not attached to the pharyngeal isthmus. Scales are cycloidal, usually small, and their body color is metallic, usually blue and silver. Tuna has dark stripes and fins. The dorsal fin consists of 9 ~ 27 closely arranged fins, and the ventral fin has 6 fins.

Tuna is a species that can keep its body temperature higher than the surrounding water temperature. They are active and agile carnivores with smooth and streamlined bodies, and they are also one of the fastest swimming pelagic fish.

Tuna can be found in warm waters, which has become a popular fish in a large number of commercial fishing and fishing activities. Due to overfishing, some tuna species, such as bluefin tuna, are close to extinction.
