Tien Chu Ve-Tsin
Tien Chu Ve-Tsin Chemical Limited is a Chinese manufacturer of honey by-products, food chemicals and additives including monosodium glutamate or MSG.
The Hong Kong unit became Tien Chu Ve-Tsin Chemical Limited of Hong Kong in the 1950s, but it was still owned by the mainland parent firm. The factory is located in Kowloon.
Tien Chu products are now found overseas in Chinese supermarkets and sold in plastic bags or blue and gold tins.
