I prepared co-polymer contain starch and beta-CD and I want to figure out if the co- polymer contain beta-CD or not. all the used method for beta-CD detection include interference of starch so, I want a method that is high selective for beta-CD
you might try inclusion complex formation with phenolphthalein. When this is complexed with beta-cyclodextrin the colour is lost. The inclusion is not formed with starch.
