Acacia Catechu Tannin (Cutch Powder & Block)

Acacia Catechu Tannin (Cutch Powder & Block) or Katha Powder is an extract of acacia trees used variously as a food additive, astringent, tannin, and dye. It is extracted from several species of Acacia, but especially Acacia catechu, by boiling the wood in water and evaporating the resulting brew. It is also known as cutch, black cutch, cachou, cashoo, khoyer, terra Japonica, or Japan earth, and also katha in Hindi, kaath in Marathi, khoyer in Assameseand Bengali, and kachu in Malay (hence the Latinized)

As an astringent it has been used since ancient times in Ayurvedic medicine as well as in breath-freshening spice mixtures—for example in France and Italy it is used in some licorice pastilles. It is also an important ingredient in South Asian cooking paan mixtures, such as ready-made paan masala and gutka.

The catechu mixture is high in natural vegetable tannins (which accounts for its astringent effect), and may be used for the tanning of animal hides. Under the name cutch, it is a brown dye used for tanning and dyeing and for preserving fishing nets and sails. Cutch will dye wool, silk, and cotton a yellowish-brown. Cutch gives gray-browns with an iron mordant and olive-browns with a copper mordant.

Black catechu has recently also been utilized by Blavod Drinks Ltd. to dye their vodka black.
White cutch, also known as gambier, gambeer, or gambir, which is extracted from Uncariagambirhas the same uses.
