longli fish and pangasius: a "fake" in the food world

in fact, the longle is not the "marine aristocrat" you imagine. it belongs to the order plaiceriformes, lives on the seabed near the coast, and is generally over 70 cm in size. the basa fish comes from the mekong delta in vietnam and the chao phraya river in thailand. it is more like an "imposter" - a giant catfish (pangasius bocourti) mainly found in southeast asia, which can reach a size of 1.5 meters and a weight of 15 kilograms.

the difference in appearance between the two is obvious: the longli fish is larger and flat, while the basa fish is fatter and smaller. however, due to the huge difference in market prices, disputes often arise due to "counterfeiting". especially when you see "longli fish" in the supermarket, you are often attracted by the low price, but it is difficult to identify its true identity.

the fate of cod and oil fish is completely different from that of basa fish and sole. cod refers to four species of fish in the genus arctogadu of the family gadidae. they are widely distributed in the ocean. they have delicious meat and high nutritional value. oil fish is called lepidocybium flavobrunneum, which is also a deep-sea fish. its meat is also delicious and tastes similar to cod, but the taste and fat content are different, and it is easy to cause diarrhea.

"fake" ingredients play an important role in the food industry. they not only affect consumers' taste but also cause health problems.

however, no matter what, when faced with these "fake" ingredients, we need to remain vigilant and improve our ability to distinguish so that we can truly enjoy the pleasure of food.
