In the world, China is the first country to produce delicious food bean paste and soy sauce rich in amino acids by enzymatic acid soybean. It is the first country to make nutritious soybean drinks-soybean milk and soybean milk; It is the first country to produce bean sprouts indoors, which is a vegetable rich in vitamin C. It is the first country to produce cheese-like foods-tofu, dried tofu and tofu skin by solidifying soybean juice.
Secondly, bean sprouts, tofu, soy sauce and gluten are called the four great inventions of China food by westerners. Bean sprouts have been recorded in Shennong Materia Medica Classic, and they are called "yellow rolls of soybeans": "The method of making yellow rolls, black soybeans are soaked in Jinghua water in the morning, and when the buds are five inches long, they are dried into yellow rolls. It takes time to get through, and it is also necessary to bring food. " As proud China people, we might as well regard Shennong, who has tasted all kinds of herbs, as the inventor of bean sprouts. Bean sprouts are a small legacy left by Shennong to our generation.
Tofu is also a great invention of China. Compared with the four great inventions of science and technology, it is actually closer to the life of ordinary people. Tofu was born in the Han Dynasty, and its qualification is old enough. According to legend, Liu An, the grandson of Liu Bang, was an alchemist at Pearl Spring in Bagongshan, Huainan, Anhui. Tofu was not refined into an elixir of life, but was created. As a by-product in the blast furnace, tofu has no magical effect of immortality, but its nutritional value is beyond doubt. I believe this legend is true.
In the process of making tofu, soybeans are ground, squeezed into slurry, and then boiled in a cooker until gypsum is added, or soy milk is pickled with green salt, which is much like a chemical experiment. Some people compare it to stone marrow, that is, the bone marrow of stone, which is quite vivid. Others call it glyceride, which is also very romantic. Secondly, sauce and gluten are also the original creations of China people in food.
