The history of human use of tannic acid
Tannic acid has existed in ancient times, and it has had a profound impact on human life for a long time.

In ancient times, although the ancestors did not use the name "tannic acid", they have gradually realized its use in practice. At that time, the art of tanning was first developed, and animal skins were an important material for the ancestors to control their bodies and dwellings. In order to make animal skins tough and durable, the ancestors found that the skins and fruits of certain trees could change the quality of animal skins after tanning. The skin after tanning is flexible and resistant to rot. In this infusion, tannic acid is a great credit.

To the Middle Ages, tannic acid was used more widely. In the field of medicine, doctors have found that plants and trees containing tannic acid can treat various diseases. In case of trauma and bleeding, apply herbs containing tannic acid, which can coagulate and relieve pain, because tannic acid can coagulate proteins and constrict blood vessels. In the matter of printing and dyeing, tannic acid is a mordant, which helps dyes to fix on fabrics, with bright and long-lasting color, and the beauty of fabrics enhances color.

Since the modern era, science and technology have advanced day by day, and the research on tannic acid has been deepened. Industry is booming, and tannic acid has become a key raw material in the tanning industry. The tanning process of large-scale production relies on tannic acid to improve the quality of leather. In the food industry, it can enhance the flavor of food and extend the shelf life. When making wine, tannic acid makes wine have a unique taste and aging potential.

Looking at the history of human tannic acid, from ignorance and initial use to scientific use, it has been used in the evolution of human civilization, such as silk thread beads, connecting the development of life, production, medicine and many other fields, becoming a good example of the integration of human wisdom and natural materials. In the future, the potential of tannic acid in various fields still needs to be further explored and expanded.
