How to eat Toona sinensis is safe?
1. Select the most tender Toona sinensis bud.
It was found that the contents of nitrate and nitrite in Toona sinensis in different regions, varieties and growth periods were different, but the contents of nitrate and nitrite in Toona sinensis were relatively low at the initial stage of germination, and the contents of nitrate in Toona sinensis increased with the continuous growth of Toona sinensis buds. After mid-April, the nitrite content may exceed the standards of the World Health Organization and the Food and Agriculture Organization of the United Nations, so it is safe to choose the most tender Toona sinensis bud.
2. Choose fresh Toona sinensis buds
Toona sinensis will produce more nitrite with the increase of storage time, and it has been a long time since Toona sinensis was picked from the tree and sold on the market, so the nitrite content is bound to increase, so try to eat fresh Toona sinensis if conditions permit. In addition, if the leaves fall off when buying Toona sinensis, it means that the nitrite content is high.
Toona sinensis should be blanched before eating.
After buying Toona sinensis, before eating, it is best to blanch Toona sinensis in boiling water for about one minute, which can remove two-thirds of nitrate and nitrite and better preserve the green color of Toona sinensis. Therefore, whether it is pickled, cold or stir-fried, you can blanch it with water, which will make it safer to eat.
4. eat with foods rich in vitamin C.
The content of vitamin C in Toona sinensis is higher than that in ordinary vegetables and fruits. If you can eat fresh Toona sinensis, vitamin C can help block the formation of nitrosamines, a carcinogen. If Toona sinensis is not fresh enough, it may be eaten with other fresh vegetables and fruits to avoid the hidden dangers caused by nitrite.
