a
Mn refers to the number-average molecular weight in kDa, Mw to weight-average molecular weight, PD to polydispersity, DA to the degree of acetylation in %, RB5 staining to the staining with reactive black 5, SD to spray-drying, RH to the hydrodynamic radius in nm, ID to the sample ID, and n.d. to not determined. ± values indicate the success of the performed experiments for the tested material.
b
Calculated via SEC using pullulan standards.
c
Calculated via 1H NMR.
