1. Quality characteristics Zheng'an ice powder seeds are shaped like rapeseeds and are brown in color. The flour becomes sticky when exposed to hot water and has strong viscosity, so it can replace agar. The processed ice pink color is bright, pure in taste and refreshing.

2. Historical origins and human relations Zheng'an ice powder seeds are perennial or annual herbaceous or vine plants. They are widely distributed in the ravines and valleys of Tuping, Liudu, Xieba, Shiping and other towns. There are wild species and artificially cultivated species. Local people have the traditional habit of cultivating ice powder seeds, which has a history of more than 400 years. During the long production and life, the local people discovered the seeds. After being processed and made into ice powder, it has a pure taste and is refreshing and refreshing. It is a high-quality snack that can quench thirst and cool down in summer. As a result, unique snacks have been formed in various parts of the county. The ice powder snacks are widely favored by food lovers and have attracted the attention of some experts and scholars from the Food Science Department of Beijing Agricultural University. In July 1985, they reached an agreement with the former technical cadres of Zheng'an County Agricultural Bureau who went to Beijing Agricultural University to study. The agreement to develop ice powder seeds, in an attempt to replace agar through in-depth research, attracted great attention from those who went to study. After the technical cadre returned to the bureau, he organized four technical cadres to conduct research on ice powder in Tuping, Linxi, Alliance, and Liaoyuan. A survey was conducted on seed production, and more than 10 germplasm resources were collected, and experimental research was conducted the following year. However, due to personnel changes, this work could not be carried out in depth. To this day, the people still practice self-planting and self-harvesting as small farmers, with more than 130 acres of sporadic planting area.

3. The work of the local government so far. Although people like to eat ice powder, Zheng'an ice powder seeds are still grown and harvested by themselves, which has not attracted the attention of the local party committee and government. , so this characteristic industry failed to exert its due economic benefits.
