Abstract:
Research to find the new uses for the olive leaf as a waste of olive oil industry is very valuable. In this regard, some efforts have been made to encapsulate the olive leaf extract (OLE) into various nanoparticles. However, there is no research on the intercalation them into montmorillonite (Mt) nanoparticle; a FDA approved carrier. The aim of the study is OLE was intercalated into Mt nanoparticle as a green and low-cost material. TGA analysis showed that the onset of phenolic decomposition increased from ۱۲۰ °C in OLE to ۱۸۰ °C in Mt/OLE composite. Maximum loading yield and loading efficiency were ۵۰% and ۸۸%, respectively. HPLC and FTIR analysis demonstrated that Mt particles absorbed the major olive phenolics. The nanocomposite preserved antioxidant capacity of OLE after ۶۰ days exposure to light by ۸۷%. These results confirm that the Mt/OLE nanocomposite can be used as an efficient antioxidant in food, cosmetics and pharmaceutical industries
