Tannin Market
Tannin production began at the beginning of the 19th century with the industrial revolution, to produce tanning material for the need for more leather. Before that time, processes used plant material and were long (up to six months).
There has been a collapse in the vegetable tannin market in the 1950s-1960s, due to the appearance of synthetic tannins, due the scarity of vegetable tannins during World War II. At that time, many small tannin industry sites closed. Vegetable tannins are estimated to be used for the production of 10-20% of the global leather production.
The cost of the final product depends on the method used to extract the tannins, in particular the use of solvents, alkali and other chemicals used (for instance glycerin). For large quantities, the most cost-effective method is hot water extraction.
Tannic acid is used worldwide as clarifying agent in alcoholic drinks and as aroma ingredient in both alcoholic and soft drinks or juices. Tannins from different botanical origins also find extensive uses in the wine industry.

Famous quotes containing the word market:
“... married women work and neglect their children because the duties of the homemaker become so depreciated that women feel compelled to take a job in order to hold the respect of the community. It is one thing if women work, as many of them must, to help support the family. It is quite another thing—it is destructive of woman’s freedom—if society forces her out of the home and into the labor market in order that she may respect herself and gain the respect of others.”
—Agnes E. Meyer (1887–1970)
