The science results showed a gradual loss of quality during storage, especially in plastic or glass bottles. What’s the interaction of polypropylene and polylactide packaging with olive oil? How much olive oil was sorbet into the packaging material?
Four commercial samples of extra-virgin olive oil have been analyzed in order to evaluate the influence of storage time on quality.
The following parameters were determined after 3 and 6 months of storage: acidity, peroxide index, absorption coefficients K270 and K230, percentage of humidity, impurity content (%), phenols content, iodine index, saponification index, color index and fatty acid content. At the same time, the effects of container type on the deterioration in quality were studied.The interaction between olive oil and plastic food packaging,
