Changzhou Guanghui Food Ingredients Co., Ltd.

Changzhou Guanghui Food Ingredients, also trading as Changzhou Guanghui Food Technology, was established in 2003 and has concentrated on a single product since then: aspartame. Annual capacity is 5,000 tonnes, and the company has stated an intention to keep investing in capacity to meet demand.

The plant is inside the Changzhou state-level chemical industry park at No. 66 Changhong West Road, Wujin District, Jiangsu. Working in a designated chemical park matters for a product whose synthesis from L-phenylalanine and L-aspartic acid generates a difficult effluent load, and the company has put more than 50 million yuan into wastewater treatment over recent years, treating all plant effluent to national discharge standards.

Guanghui frames its position in the aspartame industry around that environmental investment rather than around scale alone. Its site gives no headcount, certification list or export market detail.
