At ZAYTERRA, quality is at the heart of everything we do. From the careful selection of olives to the final product, every stage of the process is rigorously controlled to ensure extra virgin olive oil that meets the highest international quality standards.
To uphold this commitment to quality, ZAYTERRA applies rigorous standards at every stage of the production process
Our extra virgin olive oil is obtained exclusively through cold mechanical extraction at a temperature below 27°C. This process preserves the oil’s natural aromas, antioxidants, and nutritional properties, ensuring exceptional quality and authenticity.
Acidity is one of the key quality indicators of extra virgin olive oil.
Low acidity reflects healthy olives, harvested at the optimal stage of ripeness and carefully processed according to the highest production standards.
At ZAYTERRA, all our extra virgin olive oils comply with international standards, with an acidity level of below 0.8%.
At ZAYTERRA, every batch of extra virgin olive oil undergoes a rigorous quality control process before being released to the market. We perform physico-chemical analyses in accordance with international standards to verify the key quality parameters, including acidity, peroxide value, UV absorbance (K232 and K270), and other regulatory criteria.
In addition to these analyses, our oils are subjected to a Panel Test conducted by qualified tasters. This sensory evaluation confirms the absence of defects and ensures the oil meets the classification requirements for extra virgin olive oil.
At ZAYTERRA, we do everything possible to preserve a high concentration of polyphenols and natural antioxidants.
To protect these valuable compounds, we prioritize the early harvesting of olives, when their polyphenol content is at its highest, followed by cold mechanical extraction as quickly as possible.
After extraction, our olive oil is stored in stainless steel tanks under controlled temperatures and protected from light and oxygen to preserve its sensory qualities and naturally high polyphenol content until packaging.
At ZAYTERRA, every batch of extra virgin olive oil is fully traceable, from the olive groves to the final customer.
Our traceability system ensures precise monitoring of every stage of the process, including harvesting, production, packaging, and shipping, guaranteeing complete transparency and consistent quality throughout the supply chain.
At ZAYTERRA, our extra virgin olive oils can be supplied with the certifications and official documents required to meet the specific requirements of international markets and our customers, including:
Certificate of Analysis
Certificate of Origin
Organic Certification (for the Organic range)
Export documentation compliant with international regulations
