According to the Records of Sansui County, ducks have been raised in Sansui County for 600 years. Sansui duck, formerly known as Ma duck, is said to have a history of 300 years. During Jiaqing period of Qing Dynasty, a man named Song from Xiushan, Sichuan Province, drove more than 30 kinds of ducks to Sansui. He saw beautiful scenery, clean soil and clear spring water, fertile farmland dams, endless cross-country and mild climate, which were especially suitable for duck breeding and growth, so he settled down in Dong Qing and decided to develop duck farming here ... He was humble, sincere and helpful, and taught local villagers duck farming techniques. Within a few years, more and more people raise ducks, and the reputation of Ma Duck is getting bigger and bigger. Many villagers in China come here to buy ducks for breeding.

In the past, due to the lack of leading enterprises to drive and cultivate the market, the deep processing of ducks and the development of series products were weak, and farmers mainly sold them in bulk, which led to the industrial climate of "three-eared ducks". The brand of "Sansui Duck" has not started, and the outside world knows little about it except Sansui County and surrounding counties and cities. At the same time, several other famous local ducks in China are making a big fuss in the market, deeply processing and developing a series of products, especially Beijing roast duck, because "Beijing roast duck" is famous far and near, and roast duck shops are all over the country.

However, most of its pickling methods are traditional folk methods, and there is no standardized production system, which is not conducive to standardized production in factories and limits the production and development of Sansui plasma duck products. Therefore, it is of great significance to standardize the pickling processing technology to improve the quality and stability of Sansui plasma duck products. Pickling is a widely used processing method in duck meat processing and storage. Pickling duck meat can not only significantly improve the color, flavor, water retention and texture of duck meat, but also inhibit the growth of microorganisms and prevent their deterioration, thus achieving better storage effect of Sansui plasma duck products.
