|Resumo:||The aim of this study was to evaluate the quality of some glass bottles used for extra virgin olive oil (EVOO) related to light barrier properties, including clear and coloured glass in different colour intensities, glass with shrink labels, and external ceramic decoration. Some of these glass bottles available on the Brazilian market were also evaluated for closure integrity and barrier to oxygen, headspace gas atmosphere, and the quality of the product according to legislation. An increase in light barrier properties was observed for the darkest glass bottle that depends on the pigment quantity and the wall thickness. A total light barrier was obtained for glass with black shrink labels and external ceramic decoration. Closure systems used for the analysed packaging showed good integrity and low oxygen permeability, and the inertness of headspace atmosphere ensured a lower availability of oxygen for product oxidation. In general, the products met the requirements imposed in the legislation.|
