The oil without any additives is directly obtained from the fresh olive fruit by physical
methods such as mechanical pressing.
3.1.1.1 virgin olive oils fit for consumption
In the process of oil extraction of fresh olive fruit, the oil obtained by processing raw

NOTE: Lampante virgin olive oil, also known as crude virgin olive oil, is mainly used as raw
material for refining olive oil, but also for other purposes.
3.1.2 refined olive oil
The oil that lampante virgin olive oil is produced by refining, the glyceride structure of
lampante virgin olive oil does not change during the refining process, and only α-
tocopherol is allowed to be added in line with the food indicator regulations.
3.1.3 blended olive oil
The oil for human consumption made from a mixture of refined olive oil and virgin
olive oil ready for consumption.
3.2 olive-pomace oil
The oil obtained from olive pomace by solvent extraction or other physical methods.
NOTE: Olive-pomace oil does not include oil products obtained by heavy esterification of olive
pomace.
3.2.1 crude olive-pomace oil
The crude olive-pomace oil that is mainly used as raw material for refining olive-
pomace oil, that uses olive pomace as raw material, the untreated ones are extracted by
leaching process, and does not meet the requirements of edible indicators
3.2.2 refined olive-pomace oil
The oil that uses crude olive-pomace oil as the raw material and is produced by the
refining process, and only α-tocopherol is allowed to be added.
3.2.3 blended olive-pomace oil
The oil that is made by mixing refined olive-pomace oil and virgin olive oil that can be
eaten directly and meet the edible indicators.
3.3 ultraviolet absorbency
The absorbance of a sample at a specific UV wavelength.
3.4 delta E
Variation in the absorbance of a sample at a specific UV wavelength.
3.5 fruity attribute
The normal taste and smell of olive oil produced from intact, fresh, ripe or immature
olive fruits of different varieties.
3.6 median of the fruity attribute
During the sensory discrimination process of olive oil's normal taste and smell, the
value that is ranked among all the data.
NOTE: If the number of numbers in the set is odd, the value of the middle number is the median
value. If the number of numbers in the set is even, the average of the two numbers in the middle is
the median.
3.7 defect
Abnormal taste and smell of olive oil produced from dry, insect-eating, long-term
anaerobic fermentation, mixed with soil or not cleaned, preserved in brine, etc.; Or the
taste of olive fruit in prolonged contact with metal surfaces during crushing, mixing,
pressing or storage, the taste of oxidized olive oil.
3.8 median of defect
The value that is ranked in the middle of all the data during the sensory discrimination
process of abnormal taste, smell and taste of olive oil.
3.9 wax
The synthesized ester of higher monohydric alcohols and higher fatty acids.
3.10 sterol
The hydroxyl-containing cyclopentanoperhydrophenanthrene compound that exists in
the body in the free state or in the state of being combined with fatty acids to form esters.
3.11 equivalent carbon number; ECN
The sum of the carbon numbers of the three fatty acids in a triglyceride minus twice the
