Tan Dunci: 3 strokes select safe dry goods from North and South, and easily cook non-toxic New Year dishes.

The New Year Festival is approaching, and it's time to buy dry goods from North and South. But every year, preservatives and bleaches are always detected. How to choose them safely?

First of all, we must pay attention to whether the goods are kept dry and whether the packaging and labels are complete. The second is to observe carefully. For example, if the color of bacon is too red, it may be that too much nitrite preservative has been added; Scallops should be selected in a complete shape, which will not spread when squeezed, and pay attention to whether there are mold hyphae in the cracks. If so, I'm afraid it may produce aflatoxin. The third is to smell with the nose, such as mushrooms and squid, which better preserves the natural and rich fragrance. If there is a pungent smell, it may be that excessive sulfur dioxide has been added to prevent corrosion.

Preservatives of these dry goods can be removed, such as soaking in warm water at 60℃ for half an hour, or soaking in boiling water at 100℃ for 10 minute to wash off sulfur dioxide. However, although chemicals can be removed and human liver and kidney also have natural detoxification ability, it is suggested that fresh fruits and vegetables should be the main vegetables for the New Year, and a small amount of dry goods should be purchased as decorations.

Be careful not to step on the NG ingredient.

When cooking, we should also pay attention to the fact that some common dishes actually contain ng combinations. For example, it is not recommended to cook scallops with red and white radishes, because scallops are amine-containing foods, and radishes are rich in nitrate due to the application of nitrogen fertilizer in Taiwan Province Province, so nitrosamines are easily formed when cooking together.

For the same reason, squid (or mackerel, cod, saury and other seafood) contains amine, so celery with high nitrate content is not recommended.

However, these mines can be solved by a simple technique, that is, "scald them with water first." First, boil a pot of water, put down radish or celery, pick it up after the water boils again, and discard the soup to remove nitrate. Blanched radish and celery can be safely paired with seafood such as scallops.

In addition, mushrooms and scallops are usually soaked in water before cooking. Soup may contain washed dust, bacteria and sulfur dioxide. Don't pour it back into the pot to cook.
