Sufu is a second-processed bean-based food, and it is a well-known fermented condiment with national characteristics in China. After long-term development, sulphur gradually formed several major categories of green, red and white, with unique features in Guilin, Yangzhou and Beijing.
In the long-term development of fermented bean curd, small workshops gradually shift to large-scale production. The packaging of fermented bean curd is getting more and more attention. From the original ordinary ceramic jar to the fermented bean curd bottle to the present fermented bean curd plastic bottle. Sufu's outer packaging materials are increasingly diversified and more abundant. Sufu bottle packaging mainly square. This is mainly because the shape of the fermented bean curd is generally square in shape. The use of the fermented bean curd bottle on the one hand will not destroy the fermented bean curd on the one hand, and it can also hold more fermented bean curd on the other hand, which is more practical. Sulphur bottles generally have the same size of bottle mouth and bottom diameter. Glass fermented bean curd bottles have always been the mainstream of the fermented bean curd packaging market. As the fermented bean curd market continues to scale, in order to achieve long-distance transportation of fermented bean curd and reduce the cost of fermented bean curd, plastic fermented bean curd bottles have been favored by manufacturers in recent years.
