(-)-Epigallocatechin Gallate Stability in Ready-To-Drink (RTD) Green Tea Infusions in TiO and Oleic-Acid-Modified TiO Polylactic Acid Film Packaging Stored under Fluorescent Light during Refrigerated Storage at 4 °C.

The light-protective effectiveness of titanium dioxide polylactic acid (TiO PLA) nanocomposite films (T-PLA) and oleic-acid-modified (OA_TiOPLA) nanocomposite films was investigated in ready-to-drink (RTD) green tea infusions in oxygen-impermeable glass packaging. The stability of (-)-epigallocatechin gallate (EGCG) was evaluated in RTD green tea infusions in glass packaging covered with PLA (polylactic acid), T-PLA and OT-PLA under fluorescent light during 20 days of storage at 4 °C. Levels of EGCG and color change of RTD green tea infusions were determined.
