2. Look at the fatty acid content indicated on the label. The higher the unsaturated fatty acid content, the better the quality of olive oil. Similarly, the trans fatty acid content will be low. Generally, the trans fatty acid content of extra virgin olive oil is about 0. 1%, which is the laboratory data. The tea oil is at the level of 1.0 1%, so it can be said that the trans fatty acid content of olive oil.
3. It is not that the more expensive olive oil is, the better. It is also possible that the purchase price of olive oil is not so high, but the merchants deliberately bid up the price in order to make profits. Judging from the international market price, it is more reasonable to price 1L extra virgin olive oil at around 130. When consumers buy olive oil, don't forget to identify the country of origin. The best olive oil producing areas in the world classified by the European Union are Italy, Greece and Spain, and other Mediterranean countries also produce olive oil, but generally speaking, the quality of olive oil can't catch up with the first three countries.
4. In addition, you will know if the olive oil is good when you open the bottle and smell it. The first-class olive oil will have a strong smell of grass, which means that the olive oil on your hand is completely cold-squeezed. If there is no smell, there must be chemical intervention to deodorize it. Moreover, it is not clear olive oil or good olive oil. There are many kinds of olive oil with pulp precipitation, which feels like sticky juice, but it is the best olive oil.
