[0002] Mustard is a semi-dry non-fermented pickle. It is one of the famous special products in China. It is also known as the world's three famous pickles along with European pickles and Japanese pickles. Fuling mustard is one of them. Its origin is the hometown of Chinese mustard. - Fuling District, Chongqing City, since planting began in 1898, after more than 100 years of hard work, in 2009, the planting area of ​​cabbage head was 39,000 square kilometers, the output was 1.319 million tons, the total annual income was 3.1 billion yuan, and the profit and tax was 600 million yuan. It has become a traditional pillar industry that has driven nearly 160,000 farmers and 600,000 vegetable farmers to increase their income and become rich, and has obtained the protection of the region of origin. In 2009, about 700,000 tons of semi-finished products were processed in Fuling mustard, accounting for about 53.1% of the harvested output of the year. 47% of green cabbage heads are used for fresh sales and fresh consumption, but the freshness period of general fresh green cabbage heads is only 7 days at most, and the bottleneck problems of fresh-keeping and anti-corrosion of green cabbage heads have not been solved so far, which hinders the export of products, and the fresh food period is short. It restricts the stable and continuous development of its industry and directly affects the increase of farmers' income. At present, the commonly used fresh-keeping liquid components of green cabbage head include the following three types:
