Nan'an salted duck is a local famous product of Jiangxi Province. It has beautiful appearance, white color, thin skin and tender meat, plump tail oil, crisp and chewable bones, delicious flavor and tempting appetite. It has become a cured meat treasure in domestic and foreign markets. As early as the Qing Dynasty (1850), salted duck was produced in Nan'an Prefecture (that is, in the Fangwu Mine area of ??Nan'an Town, Dayu County). At that time, it was processed by each household, and the name was: "Paoyan". In order to improve the processing quality and export value, we continue to explore the color, aroma, taste and shape of "pickling", sum up experience, reform the production process, pay attention to the fattening of feathered ducks, and use auxiliary plates to shape the duck body. It becomes a peach-shaped shape, flat and dry, hence the name: "Sandwich Duck". Since the production of salted duck originated in Nan'an Prefecture, it was named Nan'an salted duck, which has a history of nearly 500 years. Nan'an salted duck won the gold medal at the first Panama Pacific International Exposition in 1915. Well-known trademark in China.
