Abstract:

The effects of various filtration materials used in the purification of sodium erythorbate on product quality were investigated. The results indicated that when ceramic membrane was used for the filtration of active carbon in crude product solution instead of filtration cloth, the product quality was significantly improved, and the purification yield was increase at the same time. Under the following operation conditions: pressure 0.15 MPa, temperature 80 ℃, surface flow rate 2 m/s, and concentration fold 15, the average membrane flux was as high as 490 L/(m2·h). When the membrane flux ranged from 350 to 390 L/(m2 ·h) and other conditions were the same as above, a 20-fold concentration was obtained, which could fulfill the need of industrial production of sodium erythorbate.

Key words: sodium erythorbate, ceramic membrane, purification
