Grades of Olive Oil
When you go to the market, you find different types of olive oils. What does extra virgin mean? What does US Fancy mean? There are two main types of gradations that you will find, IOOC standards and US standards. Fatty acid content plays an important role in determining olive oil classification. Free fatty acid measurements reflect the quality of the oil. The results are described as grams of oleic acid per 100 grams of olive oil.
The International Olive Oil Council (IOOC) has released the Trade Standard Applying to Olive Oils and Olive-Pomace Oils. The council has provided descriptions for different types of oils; with the fatty acid in each expressed as oleic acid. Some of these descriptions are given below:
Virgin Olive Oil: It is prepared by mechanical and physical means. There is no alteration to the oil after processing. Edible virgin oil has a free fatty acid content of not more than 2 grams per 100 grams. No food additives are permitted in this oil.
Extra Virgin Olive Oil: This is a type of edible oil, which has a free acidity content of no more than 0.8 grams per 100 grams. No additives are permitted in this oil.
Lampante Virgin Olive Oil: This oil is not fit for human consumption. It has a free fatty acid content of more than 3.3 grams per 100 grams. It is used for refining and technical purposes.
Refined Olive Oil: It is flavorless and without fragrance and the refined form of virgin olive oil. It has a free acidity content of not more than 0.3 grams per 100 grams.
Olive Oil: This is a blend of refined and edible virgin olive oil. It has a fatty acid content of not more than 1 gram per 100 grams.
The United States Department of Agriculture (USDA) released the United States Standards for Grades of it in 1948. These standards are still followed in the US and this has, to some extent, caused problems for consumers in purchasing the right kind of oil.
The USDA grades olive oil in the following four categories:
- US Grade A or US Fancy
- US Grade B or US Choice
- US Grade C or US Standard
- US Grade D or Substandard
- Fancy: US Fancy refers to the oil that has a fatty acid content of no more than 1.4 percent (27-30 points). It should be entirely free from any defects (27-30 points). It should have a good typical olive oil odor (18-20 points). It should have a good typical flavor (18-20 points). Finally, it should have a total score of no less than 90 points.
- Choice: US Choice refers to the oil that has a fatty acid content of more than 1.4 percent but not more than 2.5 percent (24-26 points). It should be reasonably free from any defect (24-26 points). It should have a reasonably typical odor (16-17 points) and a reasonably good flavor (16-17 points). It should have a score of no less than 80 points.
- Standard: US Standard refers to olive oil that has a fatty acid content of more than 2.5 percent but less than 3.0 percent (21-23 points). It should be fairly free from any defect (21-23 points). It should have a fairly good typical odor (14-15 points). It should have a fairly good typical flavor (14-15 points). It should have a score of no less than 70 points.
- Substandard: Substandard quality refers to olive oil that has free fatty acid content of more than 3.0 percent (0-20 points). It has more defects than what is present in the US Standard type of oil (0-20 points). It fails to have even a fairly good typical oil odor (0-13 points). It fails to have a fairly good typical olive oil flavor (0-13 points) and scores less than 70 total points.
