Kattha & cutch are extracted from wood of Khair tree.
Acacia is the botanical name of this tree and it has different varieties
like Acacia Sundra, Acacia Catechuoides & Acacia Catechu. These species of
tree are mainly concentrated in Uttar Pradesh, Bihar, Rajasthan, Gujarat
and Himachal Pradesh. The preferred locations are either UP or Bihar.
Manufacture of Kattha is an important forest-based
traditional industry in India. The Central Forest Research Institute has
developed an improved process to manufacture kattha and cutch. Manufacture
of these products is simple and does not require sophisticated technology
Heart wood of khair or acacia is cut into fine chips and
around 8-9 kgs. of chips are kept in wire net cage to avoid direct contact
with heated surface of extractor. These cages with about 25-27 ltrs. of
water (3 times the weight of chips) are placed in extractors.
Extraction is done by boiling chips with water for about 3
hours. Extracts from each extractor are mixed after filtering with the
help of muslin cloth and concentrated in an open pan on fire and then kept
in shade to facilitate crystalisation of Kattha for about 2 days. After
complete crystalisation, the curd like mass is passed through frame and
plate-type filter press, operated manually and then it is washed with cold
water which improves the quality of kattha.
It is then placed on wooden frames provided with canvas
cloth to separate traces of cutch. Finally, kattha is cut into uniform
tablets with the help of wire cutter or knife and dried in sheds. The
mother liquor after removal of kattha is further concentrated in an open
pan till it becomes viscous and then poured in wooden frames for drying.
The dried material is cutch. About 100 kgs of acacia chips give 5 kgs. of
kattha and 14 kgs of cutch. Yield largely depends upon the quality of
Katha is commonly used in
ayurvedic preparations. Besides this, it
serves as one of the major components in masticatory
i.e. chewing of betel leaf (pan) in India.
Katha after drying is applied
on lemon slice and taken regularly with empty stomach to cure piles
