When buying zongzi, don't covet the bright green color. Although the color of zongzi wrapped with traditional air-dried zongzi leaves is old and dim, it is more natural and safe. In addition, it is best to buy zongzi produced by regular manufacturers that have been sealed and packaged.

Recognition method of "seeing, smelling and distinguishing"

1. Look at the appearance. "Green-returning Zongye" has a uniform turquoise color and looks beautiful; While the primary color leaves are dark and yellow.

2. smell it. The dumplings wrapped with "green leaves" are not fragrant enough after cooking, and some of them will have a faint sulfur smell.

3. distinguish boiling water. After chemical treatment, the color of "green-returning zongye" is relatively stable. After heating, the boiled water will appear faint green. If the green color is obvious, it means that the chemical raw material content is high. However, the boiled water of zongzi made of primary color zongzi leaves will appear pale yellow.
