Researchers Radiocarbon Accelerator Unit Oxford can now determine if a whiskey was manufactured before 1950 thanks in part to the amount of nuclear experiments that were happening then. Organic material alive after the start of nuclear testing contains more carbon remains radioactive organic material prior to the nuclear tests. The barley used to make whiskey, is organic material, so scientists can examine the remains of whiskey radiocarbon looking and determine the date of manufacture.
Most of the tests are performed for the Research Institute of Scotch , a science center that seeks to maintain the quality of the distilled spirit, improve and preserve the integrity manufacturing industry products like whiskey authenticating old.
Dr. Ton Higham, deputy director of the Radiocarbon Accelerator Unit of Oxford, says that most of the whiskey samples are sent out to be after 1950. Although radiocarbon dating has helped identify several fraud cases whiskey bottles supposedly ancient, can not always identify the exact date of its creation. "If before 1950 can only say that we can not contain carbon pumps," explained Dr. Higham. Learn more about the history and evolution of the whiskey in the article " Whisky's Past and Present "(" Past and Present of Whisky ") findingDulcinea. Background: Operation of radiocarbon dating with whiskey Carbon 14 is a radioactive particle that is found naturally in the atmosphere as carbon dioxide. Plants absorb carbon dioxide through photosynthesis , and then absorb the radiocarbon animals as they eat plants. Radiocarbon levels in plants or animals would then be the same as that found in the atmosphere during its life. After the plant or animal dies, the radiocarbon begins to decay, the scientists used the ratio of radiocarbon and stable carbon present in the remains of the body as well as his knowledge of the rate at which the radiocarbon decays, to date remains .
Although all organic material collects certain amount of carbon-14 during his life, elevated levels of radiocarbon present after nuclear testing began in 1950 make plants and animals contain high levels of coal. This artificial elevation of radiocarbon is what reveals the authenticity of a modern whiskey trying to go through a history of more than one hundred years.
When the laboratory receives a sample to examine, the whiskey burn and use electricity to charge the gas resulting from the combustion, and then measure the amount of carbon 14.
Before researchers Radiocarbon Accelerator Unit of Oxford began to authenticate the whiskey for buyers and sellers, the Research Institute sent Scotch whiskey samples with known dates of creation to ensure that the method worked. Radiocarbon Accelerator Unit of Oxford was able to correctly identify the samples, and even discover that one of them had been classified incorrectly. Given its success in whiskey authentication through carbon dating, the laboratory has recently begun dating wines, although the dating of wines can be harder given the variety of organic materials used in its manufacture. Related Topic: fake olive oil The whiskey is not the only element of the food industry that has often been misrepresented. The high price of olive oil has created a new market for the dilution and fraudulent export of olive oil . In the late 90s, olive oil was the most counterfeited agricultural product in the European Union. Olive oil from other countries took to Italy and exported as Italian to achieve higher prices. Given the notorious fraud, some U.S. states, such com Connecticut, have raised the standards by which olive oil is extra virgin and classified.
