Dear Researchers,
Greetings!
I have seen many research article stated that OSA-starch modification without the treatment of isopropanol however, some of the research articles recommended diluting the OSA with isopropanol before the starch modification. I would like to know, why they are diluting the OSA in isopropanol? How it's important for starch modification? If we don't dilute with isopropanol, what kind of issue will come after the modification? I kindly request you, if someone experienced in the research area, please help me.
Thank you in advance.

Dear Kartik,
native starch modified by OSA, containing both hydrophilic and hydrophobic groups, will produce amphiphilic starch thus improving emulsification properties. 2-propanol being a “medium-polar” solvent is therefore suitable in synthesis of OSA-starch, however, ethanol being slightly more polar can also be used as described in detail here:
