Toon is one of the traditional "tree head vegetables" that folk like to pick and eat, and it is also a seasonal famous product, with a strong aromatic smell, the young shoots and young leaves of toon are fragrant and delicious, divided into two kinds of purple toon and oil toon. The usual recipes are also relatively simple, such as toon scrambled eggs, toon tofu mixed with tofu, fried toon cakes, cold toon and other ways to eat.
There is almost a week to go, which is this year's Guyu solar term, which is also the sixth of the 24 solar terms, representing the end of spring.
Before the valley rain, the toon is as tender as silk, and after the valley rain, the toon gradually begins to get old, and the taste becomes bad, so if you want to eat toon, you can still eat the tender toon before the valley rain solar term, keep in mind that after the valley rain solar term, don't buy toon to eat.
March is the season of eating toon, which has a unique flavor and high nutritional value, rich in potassium, calcium, magnesium, and vitamin B content is also more than other vegetables. However, you should know that the nitrate and nitrite content in toon is also much higher than that of ordinary vegetables, so eating toon also has potential safety hazards, and the following principles need to be followed.
1. Edible toon has potential safety hazards, and the following principles need to be followed?
As a seasonal vegetable, the price of toon is still expensive, and everyone understands the truth that scarcity is expensive, even if the price is expensive, everyone still flocks to it. But when eating toon, to understand such a thing, you must first eat fresh and tender toon. When the toon is picked, the shelf life is very short, and it will age in 1-2 days. Moreover, after the solar term of Guyu, the growth cycle of toon is also coming to an end, and the toon after the Guyu solar term may no longer be as tender and delicious as in early spring.
The unique flavor and nutritional value of toon is the most abundant in early spring, with the passage of seasons, its taste and nutrients will change, the toon after the valley rain not only tastes poor, but also accumulates more nitrite, in order to ensure the safety and deliciousness of the diet, we need to understand some safety hazards of eating toon?
Principle 1: Choose the most tender toon buds, the nitrate and nitrite content of toon will vary in different regions, due to different varieties and growth cycles.
The most important thing you should understand is that the nitrate content of toon is low in the early stage of germination, and as the toon buds continue to grow, the nitrate content in it is also rising. It is important to note that after mid-April, the nitrate levels in toon buds in most areas exceeded the standards of the World Health Organization and the Food and Agriculture Organization of the United Nations.
You can understand it this way, toon buds are the most tender in early spring, which is naturally less nitrate, and the nitrate content of toon in April is higher, especially after mid-April, when you eat toon, you should know the potential safety hazards.
Principle 2: The safety hazard in the toon bud refers to the nitrate content and nitrite content, after the toon is picked, stored at room temperature for a period of time, a large amount of nitrate will be converted into nitrite, thus bringing safety hazards.
Everyone should understand that if the toon in your home is picked from a fresh tree, relatively speaking, the nitrate contained in the toon, because it is fresh, is not stored at room temperature, there is not enough time for the toon to convert its nitrate into nitrite.
However, it should be noted that the toons you buy in the vegetable market, because of the transportation process, the picking process, through logistics and transportation to the hands of the terminal retail vendors, in this process, the toon will be stored at room temperature for at least 1-2 days. Such toon, because there is enough time, even if it is in a fresh state, but the nitrate it contains has been converted into nitrite, which is actually a safety hazard, and the easiest state to judge is that the toon leaves will fall off as soon as they are touched, and such a toon must contain a large amount of nitrite.
Principle 3: Blanching can remove nitrate and nitrite, blanching in boiling water for about 2 minutes, can remove more than two-thirds of nitrite and nitrate, and at the same time can better retain the green color of toon, whether it is cold dressing, stir-frying, as long as it is edible toon, you may wish to blanch the water first, which can greatly improve the safety of edible toon.
The aroma in the toon is mainly derived from the essential oil, which is an insoluble ingredient in water, and the blanching process is actually to remove the nitrate and nitrite in the toon, but it will not let the toon lose its original fragrance.
Principle 4: The eating season of toon is shorter, so some housewives are willing to freeze it, we must blanch it before refrigerated storage, and the toon is blanched in boiling water for more than a minute before cryopreservation, which can actually greatly improve the food safety of toon, and then put it into a sealed fresh-keeping bag after blanching.
Principle 5: Toons are salted for two or three days before eating, which is actually a very unsafe eating habit, after the toon is pickled, the nitrite content will rise rapidly, reaching a peak after the fourth day of pickling.
Blanching before pickling can greatly reduce the nitrate content and also reduce the danger of pickling toons, but the safest way is to marinate the blanched toons for more than 7 days and wait for the nitrite content to decrease before eating.
Toon is best eaten with foods rich in vitamin C, as vitamin C blocks the formation of nitrosamines.
2. What should be known about the "taboos" of eating toon?
Toon is a seasonal vegetable in spring, the main reason why we like toon, the main reason is the unique aroma and tender taste of toon, but although toon is good, it does not mean that it can be eaten casually, and many "taboos" when eating toon should be understood.

Eating toon is actually a match, and it can be matched with a variety of ingredients to reflect the beautiful taste of toon, and the most common can be paired with eggs, tofu, meat ingredients, etc.

In addition to not adding a variety of seasonings, you can not forget to blanch the toon, blanching can remove nitrate and nitrite, blanching in boiling water for about 2 minutes, can remove more than two-thirds of nitrite and nitrate, at the same time, it can also better retain the green of the toon, whether it is cold dressing, stir-frying, as long as it is edible toon, you may wish to blanch the water first, which can greatly improve the safety of edible toon.
