Translation logo
  As the level of translation of imported olive oil is no uniform requirements, so some translation translation of the olive oil importers were confused, consumers are often smoke and mirrors. But no matter how translated, consumers can pay attention to the subject of olive oil bottle is like a foreign language class identity. These flags apply only to imports from the EU olive oil, because olive oil grade by the European Union is very strict, and each batch of olive oil exports to the EU have the port inspection requirements. Therefore, China imports from the EU member-owned olive oil, or the level of the top label can rest assured. Here are some olive oil and the identity translation:
  Identify some olive oil bottle read as follows: orujo (Spanish), sansa (Italian), pomace (in English). These signs are the residue of the flag, so no matter how dealers claim to have such a logo of olive oil how noble, they just olive pomace oil. Here, we are not that good olive pomace oil, extra virgin olive oil production is actually the less expensive, many European families of olive pomace oil to heat cooking. Than just the price of residual oil extra virgin olive oil about 20% cheaper.
  Identify some olive oil bottle read as follows: only identify olive oil (in English), aceite de oliva (Spanish), or the words appear in the logo: refined (in English), refinado (Spanish), these are refined or Refined olive oil means that some people have translated into pure olive oil, 100% olive oil, they are actually refined olive oil.
  Some olive oil bottles on the logo text is as follows: extra light oilve oil, in fact, this is not a virgin olive oil, it literally is called ultra-light olive oil, it is also a refined olive oil, refined olive oil we have said above will be at the factory to increase blending virgin olive oil flavor, color. According adding different proportions of virgin olive oil will have a different name:
  Extra virgin olive oil 50% and 50% of refined olive oil blended call: more flavour (better flavor)
  Extra virgin olive oil 30% and 70% of refined olive oil blended call: medium flavour (medium scent)
  15% extra virgin olive oil and 85% of refined olive oil blended call: mild flavour (mild)
  3% and 97% of initial oil extraction blending refined olive oil called: very mild flavour, this is extra light, blending the oil is actually only a few extra virgin olive oil. As the value of virgin olive oil is relatively high, so only 3% of the blending virgin olive oil of refined oil is really just a little olive oil with incense.
  We say so many ways to identify olive oil, in fact, very simple, is marked not virgin (English), virgen (Spanish) word, not the extra virgin olive oil. Regardless of refined olive oil and olive pomace oil, refined olive oil they are after. Described above is just different name for the EU as part of olive oil, this is only applicable to exports to the EU, good olive oil filling in the EU, does not apply outside the EU except such as Turkey, Tunisia and other countries, olive oil logo norms, and from imported olive oil in the country name for repackaging.
  In addition, the difference between imported and domestic-packing approach is simple, just look at the international olive oil bottles on the bar code prefix, 690/693 is the beginning of goods made in China. The bar code is 84 in Spain, France 30/37. Bar code symbol is a commodity, with the country of origin information. So consumers can be very simple to distinguish whether each of olive oil imported.

Quality discrimination
  (A) General Principles
  1, a good olive oil has the following characteristics:
  Views: oil body translucent, thick, golden green, or golden yellow, the darker the better. The refined oil pigments and other nutrients to be destroyed.
  News: There are fruit flavor, different species have different fruit, oil products division even able to distinguish 32 different flavors such as licorice taste olives, butter flavor, fruit, chocolate and so on.

  Taste: smell, taste or simply nothing at all. That bad, or refined or blended oil.
  (B) the specific operation
  1, see name and classification
  In theory, according to the International Olive Oil Council in 2003 promulgated the "olive oil and olive-pomace oil trading standards" provides the name of olive oil can only be divided according to their level of premium virgin olive oil (or extra virgin olive oil - extra virgin olive oil), virgin olive oil (or extra virgin olive oil - virgin olive oil), ordinary virgin olive oil (or regular virgin olive oil - ordinary virgin olive oil), olive-pomace oil (olive pomace oil ) and so on. The so-called pomace oil is extracted from the olive pomace oil, extra virgin olive oil and mix again. This oil is low quality, the International Olive Oil Council standards, it can not, under any circumstances as "olive oil."
  In fact, now some of the manufacturers or distributors in order to win the competition in the market to price, and production of some labeled as pure olive oil (pure olive oil) products, such products is to be refined olive oil and virgin content olive oil to mix, the proportion of unknown, not marked on the label, from 3% -10% of them have, so poor nutrition and taste. Even low-virgin olive oil nutrition, there are some bad faith business fraud. There is strong evidence that China is selling the majority of the market labeled as "pure olive oil" is actually the product of cheap oil blending of traditional oil, dealers and consumers in the distribution and purchase of such products must be before a close look at the product test reports. Inferior olive oil test report, the formal test report of pure olive oil. From this comparison of the two test report can be seen, and inferior in the so-called pure olive oil and soybean oil fatty acid composition consistent with the fatty acid composition. Unfortunately, some regional distributors and regional distributors in China to meet the needs of the market as an excuse to sell fake fake knowledge.
  Chinese market of some nut on the label olive oil (olive kernel oil), or cooking olive oil (cooking olive oil), in fact, pure or pomace olive oil. Consumers and dealers must be careful to distinguish the names on the product label.
  Refined olive oil, there are two, A Class B Class refined olive oil and refined olive oil. Overripe, spoiled, to be insect bites, break the olive fruit can be as good as pressed olive fruit oil, but these poor quality oil, not edible. In 1900, the oil lamps used only for points. Even today, the oil is still called "Kerosene" (lampante). The early nineteenth century, some chemists have discovered a refined method of kerosene can be made of olives without scent, colorless, tasteless, edible oil. This trade will be refined olive oil olive olive oil refined kerosene called the A class. The refining process destroys the taste of olive oil polyphenol antioxidants and essential. In this refined lamp oil olive adding 3% -10% of the primary (or virgin) olive oil in the market to be glamorous labeled "100% pure olive oil" (100% pure olive oil). Pure olive oil and "light" olive oil, refined olive oil is actually Class A and virgin olive oil (Extra virgin olive oil is not) mixed oil. This mixture of oil and other levels of calories as olive oil. Most of the mixed oil containing 10% of the virgin olive oil and 90% of the Class A refined olive oil. The 90-10 models are often called "Riviera mixed" (riverra blend) or the "classic mixed" (classic).
  Olive fruit is pressed normal after the rest of the peel oil also contains 3-4% and the nut oil, but not through cold pressing extraction. At this time, need ultra-high temperature, hexane solvent (hexane solvent), and alkali extracted the oil, and then by the bleaching, winterization and deodorization treatment, removal of harmful substances in the oil, the final "production" out of the oil and tasteless , no fragrance, is the B class of refined olive oil. Will be refined olive oil and a small amount of class B real olive oil is edible olive pomace oil. This fat-free oil will be called "olive oil" is illegal in many countries.
  Frightening is that the market even if marked as original premium (or extra virgin) olive oil, in fact, many of them are blending the hazelnut oil, olive oil or other low fat, but not a pure virgin olive oil. - See American nutrition consultant Raymond Folland of the Sith "olive oil scandal" article.
  Currently, in China, some marked as "100% pure olive oil" and some cheap olive oil product sales in particular is far higher than the pure premium virgin olive oil, this is not normal, the reaction of consumers when purchasing products impetuous, and some dealers are not responsible for the behavior. Olive oil producing countries to China dumping low-quality olive oil trend. Olive oil should be brought to the health of consumers, rather than a "sucking on a pacifier." See the following news:
  1) are genuine imported olive oil is not only 35% extra virgin olive oil
  2) quality standards confusion, Consumers Association called for: as soon as possible, "olive oil, GB"
  2, to see inspection report
  By understanding the main physical and chemical indicators of olive oil can be very good and the merits of identifying the authenticity of olive oil. According to International Olive Oil Council, "olive oil and olive pomace oil trading standards," "UV spectrometry analysis of olive oil" and "People's Republic of olive oil, olive-pomace oil professional standards," the main physical and chemical indicators of olive oil including the acid value, peroxide value, fatty acid composition and ultraviolet absorbance and so on. Typically, foreign manufacturers will be the regular olive oil with olive oil for each batch released once the batch quality inspection report.
  PH (acidity), is used to determine in every hundred grams of fat free fatty acid (free fatty acids) the proportion of the indicators, also known as free fatty acids free fatty acids is oil in the "uppity" the fat part of the acidification High easily lead to oxidation, leading to oil rancidity, not edible. International Olive Oil Council and the European Union's standard display, extra virgin olive oil's oleic acid content of less than 0.8, less than 2.0, virgin olive oil, refined olive oil as a chemical deacidification process, the acidity is lower than 0.3. Therefore, extra virgin olive oil and virgin olive oil acidity is a natural acidity, and acidity of refined olive oil is the acidity of human intervention. The quality of olive oil, from the perspective of natural acidity, of course, the lower the better, but from the probability point of view, most of the original premium olive oil between the natural acidity of between 0.3-0.8. If the acidity is too low on the inspection report, such as ,0.1-0 .2, combined with peroxide value and UV absorbance, and other indicators, even if the premium on the label virgin olive oil, the product has great nutritional suspect is value is very low, or not to eat refined olive oil, or refined pomace oil.
  POV (peroxide), refers to the total content of peroxides in oils. Oil and peroxide value is the oxygen in the air oxidation of hydrogen peroxide produced is the primary product of lipid auto-oxidation, it is highly active and can continue to change rapidly, decomposition of aldehydes and ketones, and oxides, Lipid resulting deterioration. Therefore, the initial oxidation of hydrogen peroxide is the oil level mark. Hydrogen peroxide harmful to human health, peroxide value exceeds the oil can not eat. Chinese standards are usually a few milli-molar (m mol / kg) to represent, and with the International Olive Oil Council and the European Union (meq o2/kg) to represent. Original premium and the original acidity of olive oil should be in accordance with international and domestic standards is less than 20 (meq o2/kg, international), or 10 (m mol / kg, China), human intervention in the refined olive oil is less than 5 ( international and domestic). And acidity, as if the inspection report on the peroxide value is too low, for example ,1-3 (m mol / kg, domestic), and the acidity is 0.1-0.2, and the combination of UV absorbance can basically determine that the product does not belong to Extra virgin olive oil or virgin olive oil. If the peroxide value higher than the standard means that the product is stored for too long, olive oil has begun to degenerate.
  UV absorbance (absorbency in ultra-voilet), is the fat in the different wavelengths of ultraviolet light spectrum value. UV spectra of olive oil for understanding the quality of olive oil, storage status, and changes helpful. It usually shows that the level of olive oil and fresh capacities. "People's Republic of olive oil, olive-pomace oil professional standards" is not the UV absorbance of the standard, so some dealers deliberately concealed the test results. The following table is the UV absorbance of the International Olive Oil Council standards:

  As can be seen from the table, the six most important olive oil fatty acids are oleic acid, linoleic acid, linolenic acid, palm acid, palmitic acid and stearic acid. Oleic acid (monounsaturated fatty acids the most important part) of the content is the highest. This report, an indicator of quality level of products means that the level of authenticity and quality. Some domestic and international media exposure is the use of olive oil fraud scandal, blending into the traditional olive oil, oleic acid content is much lower than the standard level, or impurities.
  In addition, the fatty acid composition in the proportion of linoleic acid and linolenic acid is an important indicator, generally speaking, extra virgin olive oil in the ratio of linoleic acid and linolenic acid to less than 20:1. Theoretically, the ideal ratio of 4:1 can be achieved. In fact, the proportion of olive oil to achieve this are very rare, can achieve 6:1 to 12:1 is a good quality olive oil has.
  Olive oil quality inspection report as a "medical" report, healthy or not, good or bad, true and false, superiority and inferiority at a glance. However, the quality of olive oil identification to comprehensive evaluation, one indicator alone can not enlarge, (for example, exaggerate the low acidity, low peroxide value, and not see the product fatty acid composition and UV absorbance), while, in conjunction with olive oil sensory indicators to assess, the only way it will not blinders, to overview the overall situation, to be a smart consumer.
  3, see processing
  Extra virgin olive oil if it is (or extra virgin olive oil), are usually cold-pressed (the label will be marked with cold pressed, or cold extracted), cold-pressed olive fruit method is to squeeze out directly by mechanical and Some families squeezed juice for the principle of control, like juice, olive oil extracted by this method, pure natural, nutrition has not been any damage. Another method is refined (refined), this method is actually a chemical leaching. In accordance with China's new oil management practices, processing methods must be indicated on the label.
  4, see origin
  Origin for a great price and quality. Currently, the main olive oil producing countries, Spain accounted for one third of the world's total, the Italian quarter, one-fifth of Greece, and other oil-producing countries including Turkey, Syria, Portugal, France, Egypt and so on. Greek olive oil, especially the Greek island of Crete, the birthplace of civilization, the best quality olive oil (which is not hard to understand why Greek olive oil dealers have claimed to be operating olive oil is olive oil produced in Crete .) Annex to the EU law by 1996r1107-01/05/2004 "PDO pdo and pgi List" can prove this point. In this directory, Greece has 22 regions, of which there are eight areas of Crete were included in the protection list, there are 20 regions of Italy, Spain 4, France 4 is protected. According to statistics, Extra virgin olive oil in Greece the proportion of 75% of its production of olive oil, Italian 50%, while Spain only 30%. Good times because of the quality of tree species, and climate, latitude and other geographical conditions. Crete's olive tree is mainly Cora hi (koroneiki), the species can survive only in the island of Crete, fruity mellow and very high polyphenol content is the most famous features of the species (see California University of olive oil expert Paul Professor Luo Wosen years of research in its "variety and maturity - two pairs of the most influential factor in the quality of olive oil" article.) Crete Extra virgin olive oil olive oil accounts for 90% of the island, the ratio is quite high. Western consumers more _select_ive origin of olive oil. Italy "Olive" magazine, February 2002 90, Italian olive oil had done a survey of consumers, the question is: When you buy olive oil what it most fancy features? The survey, consumers are most concerned about the top six were: 39% origin, flavor 36.9%, 33.4% of the brand, cost 33.4%, 29.1% of taste, color depth of 26.25%.
  5, see bottles to
  Currently, the vast majority of sales of olive oil imported. There are original imported olive oil and Repackaging two. The original is the bottle of olive oil is in the exporting country's production plant canned completed, foreign large-scale professional manufacturer of olive oil over olive oil usually has tons of low-temperature storage tanks, and bottles from the mining and transportation received wide press process through the food industry haccp hazard analysis and critical control point certification and iso9001 quality management certification, therefore, the probability of the original olive oil is very high security.

  Good quality olive oil plays, on the one hand some of the inherent physical and chemical indicators, on the other hand need to be determined by the senses. International Olive Oil Council to enact a "sensory analysis of olive oil and virgin olive oil sensory evaluation method." If the conditions, consumers are better able to personally enjoy, to determine the basic quality of the product. In Western countries, such as sommeliers, as
