Many people like to eat daylily, and the most they buy is dried daylily. After all, day lilies are not grown everywhere. The treatment method is: peel the day lily and remove all the stamens. Add cold water to the pot, bring to a boil, and put the washed day lily into the pot and take it out. The time should not be too long, otherwise the fresh day lily will be sticky. Soak the cooked day lily in cold water for later use, and just rinse it with water when you are ready to eat. If you can't finish eating, you can control the water to dry and put it in the refrigerator.
In the process of making fresh day lily into dried vegetables, in order to make the color beautiful and prolong the shelf life, some merchants use sulfur dioxide to smoke day lily. Under normal circumstances, the residual sulfur dioxide will not cause any harm to the human body, but the sulfur dioxide residues in several dried day lilies sold in the circulation field are seriously exceeding the standard, which may damage the esophagus and respiratory system and even lead to death.
Experts suggest that even if you eat dried daylily, it is better to soak it in water for at least 30 minutes before eating, change the water several times, and then rinse it repeatedly before eating to remove the residual sulfur dioxide, which is safer. In addition, add a few drops of vinegar when cooking, stir-fry for a few more minutes or stew for a few more minutes. In this way, even if there is a little sulfur dioxide residue, it will decompose quickly under acidic conditions and can be safely eaten.
