Can old tofu be eaten after a few days in the refrigerator?
The old tofu has been in the refrigerator for several days and can't be eaten any more.

Tofu is sticky, so you can't eat it after washing, because tofu, like meat, is rich in protein ingredients. Under the condition of poor ventilation and high temperature, it is easy to breed bacteria and make tofu sticky. Moreover, there are many miscellaneous bacteria in the home environment, which will be mixed with harmful bacteria, some of which will produce toxins, and washing with hot water can not guarantee complete washing. So it is not recommended to stick tofu.

Tofu is a nourishing, heat-clearing and health-preserving food. Regular eating can tonify the middle energizer, clear away heat and moisten dryness, promote fluid production to quench thirst and clear the stomach.

Take two-thirds of the cooked soybean milk and put it in the bean curd jar, and the remaining one-third in the hot pulp bucket for pulping. Put the ground gypsum emulsion into the bean paste bucket. When the temperature of soybean milk is 75℃, one third of cooked soybean milk, gypsum emulsion and two thirds of soybean milk in the barrel are poured into the bean curd flower jar at the same time, so that the soybean milk in the flower jar is evenly stirred up and down. Then let it stand for 3 minutes, and the soybean milk will initially solidify into tofu flower.

(2) Swelling (squatting, raising flowers)

After sizing, the bean curd flower which has been solidified initially should continue to stand in the tank 15~20 minutes to further solidify the soybean protein. In winter, due to the low temperature, heat preservation should be added when expanding pulp. The expanded tofu flower has toughness during pouring, and the finished product has good water retention.

(3) Laying cloth

Take 1 set of old tofu boxes, put them flat, and add 1 set of tender tofu boxes. Spread bean curd cloth in the box cover to make it close to the inner wall of the box cover, and the bottom should form four bottom corners, the four corners of the cloth should be exposed outside the four edges of the ferrule, and the four edges of the cloth should be attached to the four corners of the box cover.

(4) casting

In order to make tofu reach a certain degree of aging, part of the water contained in tofu flower must be removed before pouring. The way to remove water is to divide the tofu flower in the jar into 6-8 cm square squares with a bamboo sword, so that some water can be discharged. Then use a big copper spoon to scoop the bean curd flower into the box cover to the edges of the two box covers, then turn up the four corners of the bean curd flower wrapping cloth to cover the bean curd flower and let it drain naturally, about 1 hour.
