Abstract

The invention relates to a production technology of chemical additive free fermented bean curd with a long shelf life. The fermented bean curd is characterized by preparing bean curd jelly with a specially-produced sour soup on the basis of present technologies and curing a semi-finished product with specially-produced quality guaranteeing spice powder. The technology of the invention can make protein in the bean curd semi-finished product coagulate tightly, have strong cohesiveness and flexibility, thus extending the shelf life. Using the quality guaranteeing spice powder to cure the semi-finished product not only brings the fermented bean curd a unique flavor and comfortable mouthfeel, but also substantially extends the shelf life of the fermented bean curd. Without using gypsum, brine or coagulating agent as well as chemical preservative, potential hazards possibly resulted from using gypsum, brine, a coagulating agent or a chemical preservative can be avoided.
