Pure here means that the Olive oil bottle purchased from market contains only the Olive oil extracted from the fresh Olives.

Best Answer
Any real test for purity in olive oil is going to require a lab (or at least lab equipment and supplies). The cost of that testing is going to far exceed the price of your bottle of oil.
For home use, then:
- Buy from someone reputable. Unfortunately, even reputable folks sometimes get conned by their suppliers. (If you have a local farmer you can buy from directly, that risk can be avoided).
- Taste it. Unfortunately, you'll probably only be able to notice bad fakes (even experts are fooled). As a side benefit, though, you'll also get to notice poor-quality (but genuine) olive oil.
A few countries have introduced labeling for olive oil that has been tested by an approved laboratory; if yours is one of them, you could look for certified oils.
