Smell smell at room temperature, high-quality tofu has a unique flavor; general tofu aroma is flat; poor tofu with bean flavor, smell and so on.
Touch the high-quality tofu with elasticity; the poorer quality of the tofu has poor elasticity, the surface is sticky and does not stick to hands after washing with water; the inferior tofu has no elasticity and the surface is sticky, and the sticky hand remains after the water is flushed.

Scientific storage to do this
If the tofu purchased can not be eaten immediately, it can be stored in the refrigerator, but the storage time should not be too long and it should be kept for a maximum of 2 days.
Or place the tofu in a cold water basin with a little salt, place it in a cool and ventilated place, change the water every day (with salt), store it for 2 days in summer, and store it for 3 to 4 days in winter.
Intimate
1. Tofu has a high protein content and is comparable to meat. Using tofu instead of a portion of meat in meals can avoid obesity and dyslipidemia caused by excessive intake of meat.
2. Soybean sterols contained in tofu can reduce the absorption of cholesterol, and people with high blood cholesterol can often eat tofu.
3. The digestive absorption rate of tofu is lower than that of meat. When a large amount of tofu is eaten, undigested portions cause bloating in the colon during fermentation, which can easily cause symptoms similar to indigestion. Therefore, when eating tofu or soy products, it should be appropriate according to personal circumstances.
