In the spring season, the green toona buds will fill your dining table with fragrance.

While satisfying the spiritual enjoyment, people also absorb more micronutrients.

Toon has thick leaves and tender buds, green leaves with red edges, like agate or emerald. It has a strong fragrance and is much more nutritious than other vegetables. It is a precious delicacy for banquet guests.

According to nutritional analysis, every 100 grams of toon contains 9.8 grams of protein (the highest among community vegetables), 143 mg of calcium, 115 mg of vitamin C (second only to peppers), 135 mg of phosphorus, 1.36 mg of carotene, and 1.50 mg of riboflavin.

, iron 4.5 mg, crude fiber 1.56 g.

It contains vitamin E and sex hormone substances, which have anti-aging, nourishing yang and yin effects, and has certain curative effects on infertility, so it is known as the "gestational aid".

Like many things in life, toon brings beauty to people, but at the same time, there are also people who misunderstand ailanthus.

Today, we specially invited Professor Weng Weijian, an expert in dietary therapy and health care in my country, to write an article to help readers increase their ability to discern.

In the days when vegetables are not harvesting in spring, you may think of eating toon again.

As the saying goes: "A chun in front of the house will always produce spring vegetables." There is a poem "Lin Ting Chun Ode" in the Yuan Dynasty that begins: "In the sun of Yanshan Mountain, there is a big tree on the shore of Nanming, and its name is chun..." It seems that,

From the next sentence: "Now, the words of the disciple are big and useless." You may say, I didn't see the tree, but bought toon in the market to eat, so is there any way to identify toona or ailanthus.

We say that toon or ailanthus can be identified even from the appearance of the leaves.

The roots of Toon leaves are light green and the leaf tips are yellow-brown; while the roots of Ailanthus leaves are dark green and the leaf tips are gray-green.

In addition, the edges of Toon leaves have sparse serrations; while Ailanthus leaves do not.

In addition, a bigger feature is that the number of leaves on each branch of Toon is always an even number.

For example, six pairs, seven pairs, eight pairs, etc.

The number of leaves on each branch of Ailanthus ailanthus is an odd number. It is always in addition to several pairs, and one more leaf grows on the upper end, forming six and a half pairs, seven and a half pairs, eight and a half pairs, etc.

In addition, Toon and Ailanthus can also be identified from their smell.

You can take a leaf, rub it with your hands, and smell it with your nose.

From ancient times to the present, this kind of tree can often be seen in the mountains and fields of Beijing, in front of and behind houses.

When around the Qingming Festival, the fragrance of the chun tree buds floats in the wind, it seems to be telling people: "Come and pick me, I guarantee that you will have a good meal." But then again, there has been a kind of plant since ancient times.

The tree called "樗" is commonly known as Ailanthus altissima.

It looks like toon but smells weird and unacceptable.

If you pick or buy toon leaf buds in the market without distinguishing between true and false, and do not know the quality of the product, and you mistake ailanthus for toon, it will definitely turn off your appetite.

How to identify toon and ailanthus seems to be a matter not only for traditional Chinese medicine practitioners, but also for gourmets.

Toona Toona and Ailanthus are both perennial trees, but they are not in the same family.

The former belongs to the Meliaceae family; while the latter belongs to the Sophora family.

Therefore, although the two are similar in appearance, there are still differences.
