Infrared spectra revealed a- and b-anomeric types of polysaccharides and carbohydrates.
X-ray diffractometry (XRD) suggested different diffraction patterns of polysaccharides from adulterant
carbohydrates, the former were amorphous while the later somewhat crystalline of different crystallinity.
Chiral properties of polysaccharides and carbohydrates showed big differences in specific rotation with
good correlation between the content of ‘‘pure” fungal polysaccharides and adulterants.
