The lower the acidity, the higher the quality, reflecting minimal degradation and careful handling of the olives.
-
Definition and Measurement
Acidity, measured as free oleic acid, quantifies the breakdown of triglycerides within the olive oil. This breakdown occurs when olives are damaged, improperly stored, or processed too slowly. The measurement involves titration, a chemical analysis that determines the percentage of free fatty acids present. For an olive oil to qualify as “extra virgin,” its acidity level must not exceed 0.8%. For instance, an oil with 0.7% free oleic acid would meet this requirement, while one with 0.9% would not.
-
Impact of Olive Condition
The condition of the olives at the time of harvest significantly affects the resulting oil’s acidity. Olives that are bruised, damaged by pests, or left on the ground for extended periods are more prone to enzymatic activity that increases acidity. Conversely, olives harvested carefully and processed promptly will yield oil with lower acidity. For example, hand-picking olives and milling them within 24 hours minimizes the risk of increased acidity, contributing to a higher-quality “extra virgin” product.
-
Role of Processing Techniques
Processing techniques play a pivotal role in maintaining low acidity levels. Rapid and efficient extraction methods, such as cold pressing, help to minimize the time enzymes have to break down the oil. Furthermore, hygienic processing conditions and the avoidance of excessive heat during extraction are essential. In contrast, prolonged storage of olives before processing or the use of high-temperature extraction methods can lead to increased acidity, disqualifying the oil from “extra virgin” status.
-
