It should be a normal plant-based precipitation. As long as it is not expired, there is no harm.
Olive oil has a low ignition point and solidifies easily. Some white color will appear when the temperature is relatively low. Precipitate, this is normal
It is normal for olive oil to become turbid at low temperatures. Because it contains waxes (WAX) in different proportions that will condense at low temperatures. The wax content of each grade of olive oil is regulated by the International Olive Oil Council and the EU Olive Oil Standard. The wax content standard of virgin olive oil is less than or equal to 250mg/kg. MS1907 Olive Oil
The wax content of olive oil will vary between different years/different batches of products from the same manufacturer. The wax content of olive oil depends on the olive fruit, which is affected by the origin and tree species. Even from the same origin, the same variety will have different wax content due to changes in climate conditions from year to year. It does not have a fixed freezing point like water.
The amount of low-temperature mist precipitation cannot determine the quality of olive oil. I have five or six brands of extra virgin olive oil here. The price ranges from 50-200 yuan/500ML, single bottle price, excluding luxury packaging. Under the same room temperature conditions, the more expensive the product, the more mist it contains.
Fake extra virgin olive oil can be achieved by mixing refined olive oil and ordinary virgin olive oil to achieve extra virgin acidity standards, including wax content, etc. It is no longer possible to identify mass through pure physical observation. What's more, they are making huge profits by mixing refined hazelnut oil and virgin olive oil to make extra virgin olive oil. Common standard physical and chemical tests are no longer able to distinguish authenticity.
