The content of nitrate and nitrite in the components of newly sprouted Toona sinensis is low, but as the growth time of Toona sinensis is prolonged, the more this substance will accumulate, the worse it will be for health. Moreover, a large amount of nitrate will be converted into nitrite during the storage at room temperature after Toona sinensis is harvested, which will also bring security risks, and some people will have a series of poisoning reactions after eating this food. Therefore, Toona sinensis had better be soaked in water before eating, so that it will be more reassuring to eat.
2 How long does it take for Toona sinensis to be boiled in the pot 1 minute?
Toona sinensis can be blanched in boiling water for about 1 min, which can not only remove more than two thirds of nitrite and nitrate, but also better maintain the green color of Toona sinensis, and you don't have to worry that Toona sinensis will lose its special fragrance and taste bad after blanching, because the fragrance of Toona sinensis is mainly derived from water-insoluble essential oil, and the taste and aroma will not be affected by blanching.
3 Does Toona sinensis need cold water after drowning? It is recommended to have cold water.
After blanching, harmful substances such as oxalic acid, tannic acid and nitrite in Toona sinensis will be dissolved in water in large quantities, so that the surface of Toona sinensis will also be stained with oxalic acid. Washing with clear water after blanching can reduce the oxalic acid carried by Toona sinensis. In addition, if the Toona sinensis is scalded with hot water but not cold water, the high temperature will remain in the food, which will cause the Toona sinensis to be soft and rotten for a long time, and the taste will drop. Cooking again is likely to cause the Toona sinensis to be directly fried, which will not only make the taste worse, but also make it look bad.
How long can Toona sinensis be put after drowning depends on the situation.
If the Toona sinensis is blanched and placed directly in the normal temperature environment, it may be eaten on the same day and cannot stay overnight. If it is stored in the refrigerator and the quantity is not much, it can be stored in the refrigerator for about 1-2 days. If the quantity of Toona sinensis is relatively large, it is best to store it in the freezer of the refrigerator, which can last for about half a year. It is suggested that more Toona sinensis be packed in fresh-keeping bags, which is more convenient to eat at any time.
