Elena Díaz, head of the tasting panel for the Ministry of Agriculture, has shared insights into olive oil analysis and consumer best practices. She emphasizes the importance of proper storage, specifically advising against placing oil near stovetops due to the accelerating effects of continued heat on oxidation. Díaz explains that the color of olive oil is not a reliable indicator of its quality, debunking a common consumer misconception. Her expertise provides a professional perspective on how oil is assessed for quality. Consumers should consult the label for accurate information, she suggests, rather than relying on visual cues. This knowledge comes from a leading expert in oil quality control within the government. Ultimately, informed storage and label reading are key to selecting and maintaining high-quality olive oil.
