榨菜是我国具有独特风味的民族特产之一。国内以四川、浙江榨菜最著名,但都采用老工艺生产,工艺复杂,生产周期长,劳动强度大,用食盐量多,在腌渍时有效成分随咸卤流失,使营养成分减少,而且品种单一。 Mustard is one of the national specialty products with unique flavor in China. Domestically, Sichuan and Zhejiang are the most famous mustards, but they are all produced using old techniques. They have complex techniques, long production cycles, high labor intensity, and large amounts of salt. When pickled, the active ingredients are lost with salty brines, reducing nutrient content, and the variety is simple. .
