Micro-characterization of modified microemulsions loaded with gossypol, pure and extracted from cottonseed.

Microemulsions (MEs) have gained increasing interest as carriers of hydrophobic bioactives in the last decades. However, it is still difficult to control the uptake and the release of bioactives directly extracted from plants. In this study, modified ME nanodroplets (nano-sized self-assembled liquids, NSSLs) were employed as extraction medium of gossypol, a toxic component of cottonseed.
