Categories
Supercategories
The olive oils fit in a hierarchy of categories:
Subcategories
The olive oils can be subdivided based on the level of processing, the origin of the olive oil or added ingredients:
Processing level
- Olive pomace oils(0.3% of the olive oils);
- Refined olive oils(0.2% of the olive oils);
- Virgin olive oils(83% of the olive oils);
- Extra virgin olive oils(81% of the olive oils);
- Olive oil mixes for products that combine multiple processing levels;
Origin
The products contain olive oils from a specific country or region (PDO)
Related
Products that contain mainly olive oil:
- Flavoured olive oils have extra ingredients;
- Vegetable oil mixes if more than one oil type has been used;
Ingredients
Required ingredients
There should be only one ingredient:
It is possible to combine different grades of olive oil.
Sometimes olives are mentioned as ingredient. This is however the product before processing, so not relevant here.
Optional ingredients
There are no optional ingredients.
Disallowed ingredients
Any additional ingredients, for example to create Olive oil sprays or Flavoured olive oils, indicate that the product must be taken out of the Olive oils category.
Production process/labels
The most important labels:
Nutritional information
The nutritional values of olive oils are more spread out than necessary. Some producers list the values per 100g and other per 100ml. The difference is the specific weight of olive oils (0.92 g/l). At the moment it is not possible to distinguish between per ml and per g data.
It seems that some producers do not actually measure the nutritional values, but use canonical (standard) values.
The producers sometimes give upper limits that are quite high. This might distort the statistics as these limits can not be filtered out at the moment.
For products with a per serving style nutritional table (USA/Canada), the small serving size (15ml) and the rounding used might distort the correct values.
| per 100 g/ml | min | 10% | median | 90% | max |
|---|---|---|---|---|---|
| Energy (kJ) | 3280 | 3350 | 3460 | 3770 | 4180 |
| Energy(kcal) | 788 | 800 | 828 | 900 | 1000 |
| Fat | 85.7 | 91 | 93.3 | 100 | 100 |
| Saturated fat | 4 | 12.8 | 13.8 | 15.8 | 26 |
| Monounsaturated fat | 53 | 66.7 | 70 | 79 | 83.3 |
| Polyunsaturated fat | 3.4 | 6.5 | 9.1 | 13.3 | 26.7 |
| Carbohydrates | 0 | 0 | 0 | 0 | 0.5 |
| Sugars | 0 | 0 | 0 | 0 | 0.5 |
| Fiber | 0 | 0 | 0 | 0 | 0.5 |
| Proteins | 0 | 0 | 0 | 0 | 1 |
| Salt | 0 | 0 | 0 | 0 | 0.6 |
| Vitamin E (mg) | 0 | 12 | 20 | 27 | 40 |
| Vitamin A (µg) | 0 | 0 | 0 | 300 | 330 |
| Fruit | 100 | 100 | 100 |
How accurate are the zero values? Some olive oils suggest that there are measurable values of carbohydrates, proteins and salt.
Nutriscore
Nutriscore C with nutritional values between -5 and -3.
Monitoring
Using the nutritional information (and other information) it is possible to define a quality envelope. Any products that fall outside this envelope have a quality issue. These products can be found with a Mirabelle query. Last check carried out on 6 june 2023.
