3. Result and discussion
3.1. Structural and molecular weight analyses of the
TEMPO-oxidized products
Fig. 2 displays the FT-IR spectrum of oxidized polysaccharides
which was compared with that of native one. After oxidation, two
new bands at 1619 and 1419cm−1 were observed, which were
characteristic of the stretching vibration of asymmetric and symmetric
carboxyl groups, respectively (Jin, Zhang, Yin, & Nishinari,
2006; Yang & Du, 2003). Therefore, the FT-IR showed the existence
of carboxyl groups in the derivative.
The TEMPO-oxidized products prepared from pachyman with
the NaClO addition level of 15 mmol/g were analyzed by LLS to
determine their molecular weight parameters. The weight average
values of pachyman and oxidized products which are listed in
Table 1 were 12.3×104 and 9.06×104, respectively. Thus, substantial
depolymerization occurred as a result of TEMPO-oxidization.
3.2. Water solubility and bile acid binding capacity
Table 2 shows the water solubility and molecular mass of the
derivative. Compared with the native sample, the introduction of
carboxyl groups improved the water solubility of P. cocos polysaccharides,
it would be explained by elevated hydrophilic properties
of the derivative due to oxidation, making it more soluble. The
increased solubility as a result of oxidation has been observed in
the literature (Tamura et al., 2009).
