A study has discovered the importance of post-harvest sorting of olives using a non-destructive method based on density to control olive oil quality. The research, which involved extracting oil from olives and analyzing it using advanced techniques, found that low-density olives had a higher maturation index, better oxidative stability, and higher polyphenol content, resulting in a superior quality extra virgin olive oil. This method is crucial for the industrial production of high-quality olive oil and caters to the diverse sensory preferences of consumers.
