Preparation of Dialdehyde Konjac Glucomamman
Dialdehyde konjac glucomannan (DAKGM) was synthesized by konjac glucomannan via sodium periodate (NaIO4) as an oxidant and characterized by NMR and FTIR spectroscopy techniques. The results indicated that the oxidization of KGM catalyzed by NaIO4 was highly selective for C2 and C3 of sugar units to form aldehyde group. Further, the solution behaviors of DAKGM were investigated by steady-state fluorescence. DAKGM exhibited two emission peaks at maximum wavelength 425 nm and 465 nm, respectively.
