A scanning electron-microscope is used to study the affection of temperature
ultrasonic waves and different concentrations on the appeearance of xanthan gums. A transmissive electr-onmicroscope is used to study the appearance and molecular weight of the monomolecules of xanthan. A conclusion can be drawn that xanthan molecules have uniform secondary
tertiary and quantenary structures
and that the xanthan molecule is a right-handed double helix made up of 40 subunits. The relation between their primery and senior structures has also been stated. Its molecular weight is from 6
