Before discussing whether Toona sinensis is poisonous, let's briefly introduce what Toona sinensis is. Toona sinensis is also known as Toona sinensis bud, Toona sinensis head, Toona sinensis tree and Toona sinensis day. Also called Chunmiao in Anhui. The root has two layers of bark, also known as white bark of Toona sinensis, which is native to China and widely distributed in the north and south of the Yangtze River. In ancient times, Toona sinensis was called Toona sinensis and Ailanthus altissima was called Ailanthus altissima. People in China have long been used to eating Toona sinensis, which has spread all over the country since the Han Dynasty. Toona sinensis bud is rich in nutrition and has dietotherapy effect. It is mainly used to treat exogenous wind-cold, rheumatic joint pain, stomachache and dysentery, so it is sought after by everyone.
However, Toona sinensis buds do contain a toxic substance, that is, sodium nitrite, which is a carcinogen. With the growth of buds, there are more and more such substances. After mid-April, the nitrate content in Toona sinensis buds in most areas exceeded the standards of the World Health Organization and the Food and Agriculture Organization of the United Nations. In addition, with the farther the transportation route, the longer the pick-up and release time, the more accumulation.
Therefore, we should pay attention to the following points when eating Toona sinensis: the first is to eat tender buds, the more tender the better, and generally do not eat them after mid-April; The second is to eat it immediately, don't leave it for too long after picking, and it is best not to buy Toona sinensis for long-distance transportation; The third is drowning. According to the determination, blanching can remove more than two thirds of sodium nitrite from Toona sinensis, so blanching can effectively ensure the safety of this kind of food.
We see that some food bloggers don't blanch when making Toona sinensis food, because it meets the first two conditions: tender and ready to eat, but in any case, blanching is the safest.
Do you know how to eat such delicious spring vegetables? Toona sinensis can be cold-mixed, boiled and fried, such as fried bacon. In addition, fried eggs with Toona sinensis is the most common way to eat them. The unique Toona sinensis and soft eggs make a delicious spring meal, which is worth a try ~
To sum up, it can be seen that Toona sinensis can be safely and correctly eaten, and the content of sodium nitrite, a carcinogen, is very low. This substance exists in many foods, such as sausages, so don't worry. Remember, just in case, you must blanch before eating, and because the aroma components of Toona sinensis mainly come from essential oils and are insoluble in water, blanching will not obviously affect the flavor of dishes. However, because Toona sinensis is a hair product, it is easy to induce the recurrence of chronic diseases, so patients with chronic diseases should eat less or not.
