How much is olive oil?

Olive oil is considered to be the most suitable for human nutrition among the oils found so far. High-grade olive oil for consumption is a natural fruit juice extracted from fresh or ripe olive fruits by physical cold pressing process. it is one of the woody vegetable oils in the world for human consumption in its natural state. Let's take a look at how much a card of olive oil costs.

How much is olive oil?

The price of olive oil varies according to origin and quality. Common virgin olive oil, extra virgin olive oil, pure primary olive oil, olive sunflower oil, olive edible blend oil, etc., generally virgin olive oil is about 40 pieces 250 ml, 500 ml about 70 yuan. When you buy, you must look at the production date. The shelf life of olive oil is only two years, while the production date marked on supermarket goods generally refers to the packing date.

Identification method of olive oil

1. First of all, it depends on the range of acidity marked on the bottle label. The national standard stipulates that extra virgin olive oil is less than or equal to 0.8%, and oil less than or equal to 0.5% cannot be purchased. This range is too distorted, which means that chemical deacidification is likely to be carried out.

2. If you look at the fatty acid content indicated on the label, the higher the unsaturated fatty acid content, the better the quality of olive oil, and the same trans fatty acid content will be lower. Generally speaking, the trans fatty acid content of extra virgin olive oil is about 0.03%. It can be said that the trans fatty acid content of olive oil is very low, but generally there is no zero trans fatty acid.

3. It is not that the more expensive the olive oil, 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 a profit. Judging from the international market price, it is more reasonable to price a liter of extra virgin olive oil at about 130 yuan.

4. For how to judge whether olive oil is purely imported, you can look at the drawing part of the bottle mouth. If there is a small wire drawing that can open the cover of the bottle mouth, it is the original bottle import. If there is no such thing, and the bottle label is not fine and beautiful, it can be concluded that this is not the original bottle imported olive oil.

5. How about olive oil? just open the bottle and smell it. High-quality olive oil will have a strong smell of grass, which means that the olive oil on hand is completely cold-pressed. If there is no taste, then there must be chemical intervention to deodorize. And not crystal clear olive oil is good olive oil, there are a lot of pulp precipitation, it feels like sticky juice, but it is the best olive oil.

The counterfeiting methods of olive oil

1. Take advantage of the loopholes in the policy to send high-quality olive oil for inspection and get a qualified "physical examination" report, while the actual sales quality, fake products.

2. Blending or blending traditional oils in olive oil, and labeled "pure olive oil", or "super virgin olive oil", or other custom grades, only do acidity and peroxide value determination on the quality inspection report, but not fatty acid composition and ultraviolet absorbance.

3. Directly use "fruit residue oil" as "super primary (extra virgin) olive oil" to conceal the ultraviolet absorbance of the quality inspection report.

4. Tear off the label of the expiring olive oil, replace it with a label marked with a new production date, and continue to put it on the market.

5. Foreign TIN equipment usually spray the label pattern and all kinds of information of the product on the TIN, while the counterfeiters require that only the naked TIN with the activity tag be imported, tear up the activity tag after import, and replace it with other tags that do not match the content.

6. Falsely publicize the origin of the product.

7. Use expired or expiring products as cosmetic ingredients or ingredients for other products, and continue to put them on the market in one form.

8. Chinese labels do not mark the active ingredients of olive oil, such as monounsaturated fatty acids and polyunsaturated fatty acids, so that illegal traders can take advantage of them. Some olive oil brands are vaguely labeled, such as monounsaturated fatty acids with a content of 52g to 75g / 100g, which confuses consumers. Generally good quality extra virgin olive oil contains 75g to 80g monounsaturated fatty acids.
