Natural extracts of soursop flowers, aged green tea leaves, and ginger rhizomes mitigate thermo‐oxidative degradation of palm olein during plantain chip deep‐frying

open access: yesFood Biomacromolecules, EarlyView.
Addition of old green tea leaves, soursop flowers and ginger root extract at concentrations 1000, 1400, and 1800 ppm in palm olein significantly extend its shelf‐life during frying of plantain chips. These plants' extracts are potential alternative to the use of synthetic antioxidants in preserving oil quality. Abstract This work was designed to assess
