China is the hometown of soybean, which has been planted for 5000 years, and is also the first country to develop the production of soybean products. Bean products are the crystallization of the wisdom of working people in ancient China, with far-reaching influence and wide spread. After a long period of evolution, there are more and more ways to make bean products.

Tofu, also a very common table material, is loved by many people. Tofu can be served with all kinds of dishes, whether fried or not. Tofu is rich in protein, and the amino acids needed by human body are similar to animal protein, which can supplement minerals, vitamins and cellulose needed by human body. Eating too much tofu can protect the liver, promote metabolism and improve resistance.

But tofu is very good, but not everyone is suitable, so you must pay attention to the amount when eating. There are also many kinds of tofu. There are south tofu, north tofu, lactone tofu, dried tofu and so on. South tofu is gypsum tofu and north tofu is marinated tofu, but with the progress of tofu making, glucose ester began to be used as coagulant to make tofu. Lactone tofu is soft and delicate, with more water, but its nutritional value is greatly reduced. South tofu is whiter and softer than north tofu. But the highest nutritional value is definitely North Tofu, and the content of protein is about 12.2%, while South Tofu is 6.2%, only about half of North Tofu. In addition, the content of calcium and magnesium is better than that of tofu.

Let's talk about dried tofu, which can be said to be the brother of tofu and the milk compatriot. Its early production method is the same as tofu, but its later production is thinner. Dried bean curd is a specialty in Northeast China. It is thinner than the ceiling and tofu slices in the south and can be eaten raw. It has been loved by the people in Northeast China for thousands of years. And the nutritional value is similar to tofu.

If you want to determine the order of tofu, first the north tofu, then the south tofu, and finally the lactone tofu. The nutritional value of lactone tofu has declined, but it must have. In order to avoid being greasy, it is recommended that you change your diet frequently.
