The FT-IR
spectra of MP-LRS3 and UP-LRS3 shown Fig. 3(B) and GP-LRS3
quoted from the previous study (Zhang et al., 2014) showed similar,
this indicated that there were no different in chemical groups
of LRS3 prepared by the different methods. Howener, the absorption
intensity of LRS in the band from 800 to 1200 cm1 was
weaker than that of native starch, indicating that certain conformation
changes had occurred in LRS.
