Interpretive Summary:

Technical Abstract: Properties of citrus polysaccharides such as pectin can be dependent on molecular weight (MW). For example, gel strength and solution properties of pectin are dependent on the MW, and extraction conditions for pectin can also affect MW. Thus, it is advantageous for optimizing extraction conditions to use a rapid and sensitive method to detect the MW of polysaccharides like pectin. This presentation will show the initial setup of the multi-angle light detector and interferometric refractometer for the purpose of measuring the MW of citrus polysaccharides such as pectin at low concentrations.
