Fish is rich in nutrients, high in protein and low in fat, and is very popular on the table of ordinary people. Now in addition to some fresh fish, some frozen fish are also very popular, such as " Longli. fish ". In some supermarkets or aquatic markets, you can often see this white "Longli fish". This kind of dragonli fish is already processed fish fillet , without fish bones and fish bones. It can be eaten, which saves the trouble of handling fish, and tastes delicious and tender. Many parents often buy this kind of fish for their children.
Is this tender and thornless "dragon fish" really a dragon fish? The editor chatted with a friend a few days ago and found out that the dragon fish that I often buy is not the real dragon fish, but the basa fish produced in Vietnam.
So what are the differences between Longli fish and Basa fish ? In fact, there are no small differences in terms of appearance, taste or nutritional value, but because these two kinds of fish have similar shapes after being processed into fish fillets, they are easily confused by people. Inexpensive pangasius are sold as dragon fish.
The difference between pangasius and longli
pangasius
pangasius is a kind of freshwater fish produced in Vietnam Mekong , output is very large, so the price is very cheap, because of the growth environment of the Mekong River, so the The sand fish itself has a relatively heavy earthy smell. The basa fish that are salvaged ashore are generally processed into fish fillets, and then subjected to special treatment to remove the earthy smell from the fish; the nutritional value of the basa fish is relatively simple, and many nutrients The ingredients are lower than ordinary fish. Because of its single nutritional value, it is a low-grade freshwater fish that is restricted from importing in some European and American regions.
Longli fish
Longli fish is a kind of offshore fish. Because it is picky about the living environment, it is difficult to cultivate artificially. Most of the longli fish on the market are wild, so the output of longli fish is also less. The meat of Longli fish is delicious and has almost no fishy smell, and its nutritional value is also very high. It is rich in protein , amino acid and DHA, and it is very good for the body when eaten regularly. Because there are too many fake longli fish on the market, many real longli fish on the market are now processed into fish fillets, so that they can be better distinguished from basa fish .
Try to give your children less basa fish.
The editor found that you can see basa fish in many restaurants, canteens, and even kindergartens around you, and this kind of fish is still very popular, but you must eat it as little as possible. Children eat this fish. Because the basa fish on the market are treated with ice, the surface is actually covered with a layer of "preserving water", also called tripolyphosphate. If this substance exceeds the standard, it may affect children's perception of calcium , iron Absorption of trace elements such as , , zinc , etc.
How to distinguish between basa fish and dragon fish?
When buying dragon fish, just remember one thing, only buy fresh, fresh dragon fish is pedal-shaped, so it is also called pedal fish.
