Olive Oil is rich in Vitamin E and Tocopherols. Alpha-tocopherol is the predominant form of Vitamin E in Olive Oil. It acts as a powerful natural antioxidant that protects the lipids in the oil and provides health benefits, such as supporting immune function and cellular protection.
I. – Oxidation Test (Oxidative Stability)
Alpha-tocopherol is an antioxidant that protects the oil from oxidation. If you have a good quality olive oil, it should resist oxidation better than other oils.
For a basic test, place some oil in a small dish and expose it to air for several days.
If the oil starts to go rancid quickly (gives off an unpleasant smell or changes its taste), it is possible that it is low in antioxidants such as alpha-tocopherol and is adulterated.
II.- UV (ultraviolet) Light Test
Alpha-tocopherol helps protect olive oil from the damaging effects of light.
Place a small amount of Olive Oil in a clear glass jar and expose it to direct sunlight or UV light for a few hours.
If the oil retains its colour and does not change its odour, it may be a sign that it contains antioxidants such as Alpha-tocopherol that protect it. However, a change in colour or aroma would indicate a lower amount of antioxidants and it is adulterated.
