No one knows the benefits of Mediterranean diet. It is emphasized that taking good oil is good for health. The key here is definitely "olive oil". But what is the best olive oil? How to distinguish between levels? What is virgin? Let Heho nutritionist Yunzhen take you to analyze the secrets of olive oil at once!

See foreign countries so highly value olive oil, and specialized oil maker, which has the bad reputation of olive oil called "golden liquid", which can't help but make consumers and luxury paintings top-notch. However, when I saw Lin Yan's products on the shelf, there were many product names that people couldn't understand. I wanted to buy them but didn't know how to choose them, and I didn't even get the olive oil.

{Oleic acid} is considered a single infertile and fatty acid (MUFA) of Omega-9, which can reduce human calcine . LDL-c, and boost good tart sterol HDL-c. If the dietary fat and fat are replaced by MUFA, it is beneficial to reduce the occurrence of cardiovascular diseases.

And virgin olive oil retains a relatively rich nutrient, such as antioxidant vitamin E, saccharin, and polyphenols. These ingredients give olive oil a variety of flavors and are also a key to health. Among them, the "olocanthal" that makes us taste a little spicy is said to be a very powerful anti-inflammatory compound.

Olive oil classification standard

From the moment of olive growth, due to different climate, soil, planting, harvesting methods, etc., the quality of olive oil begins to be divided into high and low after being squeezed and extracted. According to the Taiwan National Standard CNS "Edible Olive Oil and Olive Meal Oil", edible olive oil can be divided into 7 levels: special virgin olive oil, high-grade virgin olive oil, general virgin olive oil, refined olive oil, olive oil, refined olive oil, and olive meal oil.

What is acid price?

The so-called acid price (Acidity) is 1 gram of oil and fat to neutralize acidity, which reflects how many floating fatty acids are in the oil. The higher the value, the higher the degree of oxidation of the oil. In contrast, the lower the acid price, the fresher the quality. According to the Food and Drug Administration, the acid price exceeds 2 mg KOH/gram, which indicates that the oil has deteriorated and oil has been produced and the oil is required to be changed.

Can olive oil be stir-fried and fried?

I always think that olive oil is only used to mix it for salads or bread and soy sauce, so it is hard to use it for stir-frying? In fact, the cooking method suitable for oil depends on "smoking points", and the smoke points lower than the oil will not cause excessive oxidation of fat. Virgin olive oil has not been refined and its smoke point is lower, about 190℃. Generally, the temperature for families to stir-fry or fry is between 140℃ and 180℃, so it is no problem to use it for frying and frying.

However, during the high-temperature cooking process, the antioxidant quality of olive oil will be damaged, and some nutrients will be lost due to high-temperature. Since virgin olive oil is chosen to eat it to improve its benefits, you might as well change it to other oils when frying, and your purse will not be so worried. If you want to eat more complete nutrients, it would be better to use virgin olive oil for food, cooking, or cooking, or to low-temperature cooking.
