How long should tofu be left to stand after ordering

After ordering tofu, it is generally necessary to let it stand for 20 to 30 minutes, and the actual time is affected by factors such as the type of coagulant, ambient temperature, and tofu taste requirements. The type of coagulant has a direct impact on the settling time. When using gypsum as a coagulant, the settling time is relatively short, about 20 minutes can complete the solidification process. Gypsum coagulates rapidly, which can promote the protein in soybean milk to form network structure rapidly. When using brine as a coagulant, the settling time needs to be extended to about 30 minutes. The solidification rate of brine is slower, but the resulting tofu has a finer and denser texture. Gluconolactone, as a commonly used coagulant in modern times, has a settling time between the two, about 25 minutes to complete coagulation.

The ambient temperature will significantly affect the settling time. Under high temperature conditions in summer, the solidification reaction rate accelerates and the settling time can be shortened to 15 to 20 minutes. Under low temperature conditions in winter, the solidification process slows down and needs to be extended to 30 to 40 minutes. When the temperature is too low, incomplete solidification may occur. The container can be placed in warm water to help maintain a suitable temperature. When the indoor temperature is maintained at around 25 degrees, a relatively stable solidification effect can be obtained. The taste requirement of tofu determines the final resting time. When pursuing the taste of tender tofu, the settling time should be controlled at 15 to 20 minutes, during which the tofu has a high moisture content and a soft texture. When old tofu is needed, it should be left to stand for more than 30 minutes to allow the water to fully drain and form a compact structure. Products such as dried tofu that require further dehydration need to be pressed after being left to stand. Different cooking methods have different requirements for the hardness of tofu, and the settling time can be adjusted according to actual needs.

When making tofu, pay attention to the solidification state. When soybean milk presents uniform flocculent solidification and clear yellow water is separated, the solidification is completed. Avoid shaking the container during the static process to avoid affecting the molding effect. Tofu made with traditional techniques has high nutritional value, containing rich and high-quality protein and calcium. Moderate consumption can help supplement the nutrients needed by the human body. Tofu can be cooked with a variety of ingredients, but those with renal insufficiency need to control their intake. Fresh tofu should be soaked in cold boiled water and refrigerated. It is recommended to consume it within two days to ensure the best taste and nutrition.
