0 1 Keep away from brightly colored dried zongzi leaves.
If there are no fresh zongzi leaves in our area, then we will buy some dried zongzi leaves, whether reed leaves or other zongzi leaves. As long as it is dried or dried, the color of zongzi leaves will become dull, and the original bright green will not be seen at all. The so-called green-turning leaves will have bright green and look attractive, but don't buy such leaves, because there is no technical means to keep the sun-dried leaves in their original colors, even brighter than the original ones.
02 odor recognition
Really healthy and good zongye can smell the fragrance of zongye from a distance, whether it is reed leaves or dried pineapple leaves. Pick up the Zongye and smell it. There is no other smell, only the faint aroma of Zongye. Such Zongye can be selected with confidence. Moreover, if you smell it, you will smell a particularly strong aroma, which is completely artificial. Some of them will smell of sulfur, mildew, or even beautiful colors without the slightest smell of zongzi leaves, so you must not buy it.
Distinguish by touch
When buying zongzi leaves, people usually identify the quality of zongzi leaves by their appearance and smell. In fact, you can also identify it with your hands. For example, if you touch the really healthy zongzi leaves with your hands, you will feel the softness of the normal dry zongzi leaves, but the soft and hard ones are not uniform, so try not to buy them. Most of these zongzi leaves are "manual".
Pay attention to check whether it is an old leaf.
The cost of the clan industry itself is not high, and all the larger businesses will not sell the clan industry in the next year. However, it is not excluded to bundle the accumulated leaves in the next year's inventory with the new leaves for sale. Therefore, when selecting zongye, we should pay attention to check the color of a whole bundle of zongye, and smell whether some zongye have a musty smell. If there are such leaves in a whole bundle of leaves, don't choose them.
05 Check the "thickness" of zongzi leaves.
Whether you buy reed leaves or dried pineapple leaves, these leaves have their own thickness. Without too much processing, their thickness is not particularly symmetrical. It is well understood that reed leaves are the same in nature as leaves, and it is impossible to grow as thick as a leaf. However, the thickness of the processed leaves is surprisingly consistent, and such leaves are very suspicious.
06 identify the authenticity after cooking
Although we can't use this method to distinguish the quality of zongzi leaves when we buy them, if we find the problem of zongzi leaves before we love to wrap them, then we can know it earlier. After the truly healthy leaves are boiled with clear water, the boiled water will appear dark yellow, while those leaves that turn green will turn light green or dark green, which is the result of "bleaching" the leaves with chemicals such as copper, arsenic and mercury.
It is best to choose dry leaves instead of fresh ones.
There are many areas where zongzi leaves are not produced, so many people like to buy some so-called vacuum-packed fresh zongzi leaves to wrap zongzi, thinking that zongzi wrapped with such zongzi leaves will definitely taste better. Actually, you are wrong. Compared with dried leaves, jiaozi wrapped with dried leaves tastes better. Besides, you don't know the sanitary condition of fresh zongzi leaves in the packaging process. The Dragon Boat Festival is hot and it is also a good season for bacteria to breed. Once the fresh zongzi leaves are polluted, it is easy to eat bad stomachs.
Finally, I will teach you a way to distinguish healthy zongzi. Many people don't make zongzi on the Dragon Boat Festival. On the one hand, Zongzi itself is too sticky, which is not good for gastrointestinal tract. On the other hand, they don't have the time and patience to make zongzi, so everyone will choose to buy some ready-made zongzi to adapt to this situation. Then, when buying zongzi, don't look at the color of the leaves. A really healthy zongzi is dark black or yellow, and it can't be that bright green. Smell it. Healthy zongzi has a strong brown flavor. Don't buy those zongzi with bad smell, such as those with unclear aroma and sulphur smell. Zongzi wrapped in green leaves may directly lead to copper poisoning after eating, so the possibility of death due to renal failure will increase.
