Where is the largest mustard planting area in China?

Since the early 1980s, mustard introduction experiments have been carried out in Hebei, Sichuan, Guizhou and Heilongjiang provinces. At present, the planting area of mustard in China is 800 mu in Sichuan Province and 200 mu in Guizhou Province. Because Dalian has a history of planting mustard for more than ten years, the planting area is more than 654.38+0. 1 10,000 mu. The mustard seed produced is divided into black mustard seed, yellow mustard seed, white mustard seed and brown mustard seed. The content of allyl isothiocyanate produced by light yellow hydrolysis is the highest, so mustard seeds with large yellow seeds should be selected as raw materials when producing mustard sauce. At present, the raw materials of mustard sauce in China are all produced in Shaanxi, and the quality is the best. Although mustard seed production in China is very large, it has not been fully and reasonably utilized. Except a few processed mustard powder, a large number of mustard seeds are exported as raw materials. Therefore, the development and deep processing of mustard series products in China need to be improved.
