Storage science offers clear guidance for consumers seeking to maximize the nutritional benefits of extra virgin olive oil. The first rule is essential: keep bottles sealed and completely full. Headspace directly accelerates oxidation, making half-empty containers lose their antioxidant content 2–3 times faster than full ones.
Second, store olive oil in dark cupboards rather than on illuminated kitchen shelves or near heat sources. Light and temperature fluctuations both accelerate the degradation of polyphenols and vitamin E. Third, establish a consumption timeline: use opened bottles within 2–3 months to ensure maximum concentrations of protective bioactive compounds.
These straightforward practices—rooted in controlled experimental data—help preserve the health benefits that make extra virgin olive oil a valuable dietary component. Read the full article on GMJ Newsroom.
