Figure 8From: Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrupConcentration ratios vs. J v of 19.0 g/L chitooligosaccharide syrup. Long-term experiments were carried out at 16.0 bar for enrichment of DP 6 to 8 chitooligosaccharides. The flux was about 102.4 L/(m2 h) at the beginning, whereas it decreased heavily when the concentration rate was 6.0.Back to article page
