From: Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrup

Figure 7

pH values vs. R obs of chitooligosaccharides at 16.0 bar and 40°C in NF process. The effects of pH ranged from 5.0 to 9.0 on rejections of glucosamine and DP 2 to 8 chitooligosaccharides were investigated. The Robs of chitooligosaccharides increased with pH, especially for the monomer, dimer, trimer, and tetramer. In addition, the flexibility of chitooligosaccharides was well conducted by pH.
