Abstract

The invention provides a novel ecological bean curd and a preparation method of the bean curd. The ecological bean curd takes probiotics fermentation liquor as a coagulation point preparation and is prepared from point system soybean milk. The probiotics fermentation liquor is made by adding and fermenting probiotics raw powder in the soybean milk. The novel ecological bean curd is milky white incolor, strong in elasticity, pure in bean smell, fine in taste and rich in quality protein, ferrum, calcium, phosphorus, magnesium and other various trace elements needed by human body. Without use of plaster, brine and other substances, the novel ecological bean curd is a popular green nutritional food being purely natural, safer and healthier.
