Lactic acid is widely used in food, medicine and organic chemical industry. Using glucose as carbon source to ferment lactic acid, the calcium salt method was used to separate lactic acid, which had long production cycle and low product yield.

The lactic acid extractant developed by YILAISITE new materials has high adsorption capacity and good selectivity, which is suitable for extracting and separating lactic acid from fermentation broth. It has the advantages of short production cycle and high product recovery rate.

Citric acid is a food additive of traditional Chinese medicine. In the past, it was also separated from fermentation broth by calcium salt method, which consumes a lot and costs a lot. The citric acid separation agent developed by YILAISITE new materials can improve the recovery rate of citric acid.
