Effects of pH and Ionic Strength on Emulsifying Properties of Chitosan

Abstract:

Chitosan has excellent emulsifying properties.Emulsifying activity and stability of chitosan were determined using turbidimetric method and integrated light scattering technique.The effects of pH and ionic strength on emulsifying properties of chitosan were studied in the manuscript.it was found that emulsifying activity and stability of chitosan continuously increased with a rise of pH values from 3.9 to 5.9.Emulsifying activity of chitosan initially increased and reached at the maximum value(0.34 mol/L),then decreased with the increment of ionic strength.Ionic strength had no distinct influence on emulsifying stability.
