Four taboos of olive oil

Four taboos of olive oil: do not fry at high temperature, do not eat more, do not mix olive oil with acidic food, and do not put olive oil in the sun.

1, which is not suitable for high-temperature frying.

Some trace substances contained in olive oil are not suitable for high-temperature frying. If cooking at high temperature, its nutrients will be destroyed. In addition, monounsaturated fat in olive oil will smoke when heated, which will easily become unhealthy, so try to use cold salad instead of frying olive oil.

2, should not eat more

Although the nutritional value of olive oil is high, like other edible oils, the calories of olive oil are also high. Therefore, the daily consumption of olive oil should not exceed 30 grams, and should be limited to below 25 grams.

Don't mix olive oil with acidic food.

The mixture of olive oil and acidic food will make it deteriorate and produce harmful substances, so it is not suitable for mixed consumption.

4. Don't put olive oil in the sun.

Olive oil should not be exposed to the sun, which will deteriorate it and affect food safety.

Selection of olive oil

1, look at the ingredient list: the ingredient list can only contain one extra virgin olive oil, and other contents indicate that the olive oil is impure and mixed with other inferior olive oil.

2. Look at acidity: According to international standards, the acidity of extra virgin olive oil is lower than 0.8%, and trans fatty acids are lower than 0.05%. Beyond this standard, it is not extra virgin olive oil. However, if these two figures are particularly low, we should be alert to whether they have been sour.

3, look at the bottle: the bottle can reveal the quality of olive oil from the side, because olive oil contains antioxidant unsaturated fatty acids, so it needs to be kept away from light, so the packaging of good olive oil must be dark glass (usually dark green, black, brown) or completely opaque material.

4, look at the capacity and shelf life: because olive oil is easy to be oxidized after opening, it is not appropriate to choose large-capacity olive oil. You can choose a moderate capacity according to your own needs.
