How can I check the purity of pectin extracted from banana peel?

08 February 2024 1 3K Report

What kind of test should I do for purity check of pectin?

I follow LC based techniques for impurity identification. Depending on the MW of the polysaccharides you purposed, SEC chromatography combined with either MS or PAD (as the first choices) or UV/RID would be efficient. Since RID is a kind of bulk detector keep it as the last option.
