The sensory analysis of olive oil constitutes a fundamental tool in determining the commercial grade of oil. To obtain this certification, the oil must pass through the analysis of a group with 8 to 12 people, trained and qualified by regulatory bodies, called ‘panel test’, which will feature the organoleptic properties of the oil, setting its commercial classification. Sensory analysis has significant importance to judge the final product quality. These tests are performed in specific laboratories, other organizations, or if the manufacturer sells large amounts of oil in committees within the company. Olive oil, according to Brazilian standard, can be classified in a virgin olive oil, olive oil, refined olive oil and olive pomace. The tests performed in oil samples are visual, olfactory and gustatory. The aftertaste of the process is the gustatory-olfactory sensation left by the oil in the mouth, after being swallowed or spat out. This exercise facilitates the perception of the characteristics of a particular oil, there may be positive and negative aftertaste. The tasting room must contain accessories, oil heater, tasting booths, site sample preparation and cleaning materials and room to open ‘panel’ training. This review aimed to present how should be carried a sensory analysis of olive oil, the place to carry out this analysis and the main defects found in an olive oil quality.

Instrumental Technique

The organoleptic profile of a Virgin Olive Oil is a key quality parameter that is currently obtained by human sensory panels. The development of an instrumental technique capable of providing information about this profile quickly and online is of great interest. This work employed a general purpose e-nose, in lab conditions, to predict the level of fruity aroma and the presence of defects in Virgin Olive Oils. The raw data provided by the e-nose were used to extract a set of features that fed a regressor to predict the level of fruity aroma and a classifier to detect the presence of defects. The results obtained were a mean validation error of 0.5 units for the prediction of fruity aroma using lasso regression; and 88% accuracy for the defect detection using logistic regression. Finally, the identification of two out of ten specific sensors of the e-nose that can provide successful results paves the way to the design of low-cost specific electronic noses for this application.

Extra virgin olive oil (EVOO) is one of the most distinctive ingredients of the Mediterranean diet. There are many properties related to this golden ingredient, from supreme organoleptic characteristics to benefits for human health. EVOO contains in its composition molecules capable of exerting bioactivities such as cardio protection, antioxidant, anti-inflammatory, antidiabetic, and anticancer activity, among others, mainly caused by unsaturated fatty acids and certain minor compounds such as tocopherols or phenolic compounds. EVOO is considered the highest quality vegetable oil, which also implies a high sensory quality. The organoleptic properties related to the flavor of this valued product are also due to the presence of a series of compounds in its composition, mainly some carbonyl compounds found in the volatile fraction, although some minor compounds such as phenolic compounds also contribute. However, these properties are greatly affected by the incidence of certain factors, both intrinsic, such as the olive variety, and extrinsic, such as the growing conditions, so that each EVOO has a particular flavor. Furthermore, these flavors are susceptible to change under the influence of other factors throughout the oil's shelf-life, such as oxidation or temperature. This work offers a description of some of the most remarkable compounds responsible for EVOO’s unique flavor and aroma, the factors affecting them, the mechanism that lead to the degradation of EVOO, and how flavors can be altered during the shelf-life of the oil, as well as several strategies suggested for the preservation of this flavor, on which the quality of the product also depends.
