Storage method

1, the leaves of zongzi are all green, and after a period of time, they will gradually turn yellow-green or yellow-brown. Experienced old people will soak the leaves in water for preservation, or hang them to dry, and then soak them in water for recovery when eating, but neither of these methods can keep the leaves green all the time.

2. In recent years, some zongzi manufacturers have added industrial copper sulfate and industrial copper chloride to the water when soaking zongzi leaves, so that the zongzi leaves can achieve the effect of "turning green".
