Gunpowder , compass, papermaking, and printing are the four major inventions of ancient China recognized by the world. In fact, in addition to these four inventions, there are three inventions in ancient China that seem to be ignored. According to the modern nutritional , these three inventions include the three main nutrients required by the human body, but their scientific value is far underestimated.
1. plant protein extraction technology
To put it simply, it is the invention of tofu. Tofu was invented by the Chinese, and its history can be traced back to Han or Warring States Period . Tofu is a food product in daily life. If it were the academic term for , biological science , it was plant protein. Therefore, it can be said that the earliest plant protein extraction technology in the world was invented by the Chinese, and its extract was tofu. In fact, the name of protein can also be called tofu or tofu, but unfortunately it was later named after the ingredients in the eggs.
2. Starch extraction technology
vermicelli was also invented by the Chinese. The raw material for making vermicelli is starch. First, there must be starch extraction before it can be made. This is self-evident. Starch is actually what the Chinese call flour noodles, and the vermicelli production technology is said to have been found in the Spring and Autumn Period. Unfortunately, it is also regarded as a kind of ordinary food production.
3. Plant fat extraction technology
is what we often call oil pressing. Some people believe that the extraction of vegetable oil was invented at the same time by several ancient civilizations, while others believe that it was the earliest invention of the Chinese. In any case, China is at least one of the first countries to master oil pressing technology. It is said that it appeared before the Han Dynasty. The extraction of a large amount of vegetable oil is mainly the extraction of cabbage-type rapeseed oil. Cabbage-type rapeseed This plant is native to China and was called "Brassica" in ancient times. According to the current botany, it is the type of plants such as cabbage, mustard green in Crusade family . Since the origin is in China and it is the earliest cultivated country of this plant, it is natural that the Chinese first invented the oil extraction technology of this plant seed. Edible oil is a kind of fat, and edible vegetable oil is plant fat.
In this way, the other three major inventions in ancient China were: tofu, flour noodles, and vegetarian oil. People have become accustomed to these three titles, but they ignore the great scientific significance of them. Tofu, flour noodles, and vegetarian oil are the originators of plant protein, starch and plant fat.
