How to choose good fish

The pangasius comes to our supermarkets not in the whole look, and generally in the form of the fillet sealed in vacuum packing. More rare in the form of a stake and a carcass.

They are considered as the most suitable for the use.

But if you can buy only fillet, remember the following:

1. Fillet of a pangasius happens four flowers: white, white-pink, red and yellow. Color of meat depends on with what fed an animal and in what conditions it was grown up. It is better to give preference to white or poorly pink meat as red says that the pangasius lacked oxygen, and yellow color appeared from behind unbalanced food and the close habitat.
2. Give preferences to pieces of the small size. They are more gentle, they contain less ice. Ice glaze will be surely present, but in number of no more than 10% of all weight of fillet.
3. Ice has to be transparent. If also it is a lot of it with a yellowish shade, means — goods peremorozhen.

Important! Distributors often give a pangasius for sole. But it is absolutely other species of fish and it is much more expensive. Their main difference: color of meat and availability of fat. Sole fillet thin, transparent and without fat layer.

Harmful properties and contraindications

All harm of a pangasius of which shout from all directions is connected only with production. The fact is that the Mekong River and its pool cannot brag of purity of the waters.

It proceeds through densely populated areas with the developed industry because of what in waters of the river a number of hazardous substances merges. Therefore a conclusion logically arises that all caught fish is not suitable for the use.

But large enterprises for production of a pangasius do not catch it in open reservoirs, and grow up on special farms where carefully watch purity of water.

In addition, because of refusal of the USA of a pangasius because of his discrepancy with sanitary standards, the main producers toughened quality control of products at all production phases, beginning from cultivation of fish and finishing it with cutting. Therefore only fish from small producers and underground firms can be mean. Such products will hardly filter on counters of large hypermarkets which carefully watch the goods.

Important! Fish can be contraindicated only to allergic persons. They are recommended to use her small pieces to check reaction of an organism.

Consumption rate

Fish has to be present at the menu of any person. Nutritionists persistently insist on what it is very useful to arrange weekly fish day. Even if you not the supporter of fish, it is necessary to eat at least 100-140 g a day.

Aged from 10 up to 12 months it will be useful for the formed children's organism to eat 40 g. In one and a half years the kid has to eat 80 g, and in two years — on 100 g of a pangasius. Further, if the child's organism normally reacts to a product, it is possible to include it in a diet with a frequency of times a week.

How to store

In the fridge of fillet it can be stored at a temperature about 0 °C within 8-10 days. The period of storage increases in the freezer where it is possible to lower temperature to -17 °C, up to three months. For this period neither useful, nor tastes disappear.

It is possible to keep a product in a salty and dried look.

Thus, we were convinced that a pangasius — tasty and useful fish. You should not be believed blindly in all rumors about its harm. Follow the rules of the choice of goods and do not refuse to yourself a fine dish.
