Qian'an Glutinous Corn is a protected geographical indication product.

　　Qian'an County is located in the Jilin Corn Golden Belt, one of the world’s three major corn golden belts. The glutinous corn is a uniquely excellent product nurtured on this "Qian'an Plateau," characterized mainly by its weakly alkaline soil. For many years, the Qian'an County Party Committee and County Government have focused on developing glutinous corn as a leading industry for green and organic food production, and have already formed a trend toward specialization, scale, intensification, and industrialization. As of now, the county has developed two specialized glutinous corn villages, boosting the total planting area to 80,000 mu and an annual yield of 300 million ears. There are now 48 enterprises specializing in the production and processing of glutinous corn. With its superior quality, rich nutrition, and fragrant taste, Qian'an Glutinous Corn is exported to countries and regions including South Korea, Beijing, Shanghai, and Guangzhou.
