She says food adulterations may occur both as a result of man-made economic fraud or as a natural process.  \u003cbr/\u003e              \"The goal of this prototype, developed here at ENEA's center in Frascati, is to reveal cases of food adulteration resulting from a natural or man-made process. For example, the presence of low-quality oils mixed with extra virgin olive oil, of methanol in alcoholic beverages, of sugars and sweeteners not listed in fruit juices' labels and, mostly, histamine in fish products,\" Puiu says.\u003cbr/\u003e              Adding cheap oils with extra virgin olive oil or sweeteners not listed on labels to fruit juices are a case of economic fraud as is the presence of methanol in liquors.   \u003cbr/\u003e              Methanol is a type of alcohol mainly used for industrial purposes. Unscrupulous criminal networks sometimes add it to liquor because it's cheap and impossible to distinguish from drinking alcohol. Methanol is highly toxic for humans and can result in death or permanent health problems, including blindness. \u003cbr/\u003e              Another harmful element food authorities are on the lookout for is histamine - it develops in fish that hasn't been properly frozen or stored, causing food poisoning. \u003cbr/\u003e              At the ENEA laboratory in Frascati, Puiu shows how the system works. \u003cbr/\u003e              Scientists first fine-tune the laser and then direct it toward a small food sample. \u003cbr/\u003e              \"The system is based on laser photoacoustic spectroscopy, it uses an infrared laser source. A laser beam hits the sample and interacts with it. Thanks to absorption spectroscopy we can check whether the sample's molecules absorb laser radiation at a given wavelength,\" Puiu says.\u003cbr/\u003e              This means that whenever a sample contains cheap oils, methanol, sweeteners or histamine it absorbs the laser beam and immediately sends a message to a connected computer, alerting scientists about these food alterations. \u003cbr/\u003e              By employing infrared laser, scientists are able to obtain specific results that wouldn't be possible with other sources such as flashtubes, black-body halogen lamps or flash lamps, Puiu adds. \u003cbr/\u003e              \"Laser is very selective compared to other conventional sources so it allows us to spot adulterated molecules with high precision during a product's testing\", the scientist explains. \u003cbr/\u003e              Puiu takes an olive oil sample and tests it through the system. In a matter of seconds the food laser sends its verdict: the olive oil isn't pure, contrary to what was advertised on the bottle. \u003cbr/\u003e              A message then appears on Puiu's computer screen: like a traffic light, a red button signals the presence of food alterations while a green button will mean the sample is untainted. \u003cbr/\u003e              \"During our test we found that a sample of olive oil bought at a supermarket was adulterated, meaning that low-cost oils have been mixed with olive oil here\", Puiu confirms.. \u003cbr/\u003e              The scientist then conducts the same test on a small amount of red wine. In this case the system gives the green light as the sample doesn't contain any methanol. \u003cbr/\u003e              ENEA's food laser has been devised to raise a first alarm about dangerous or fraudulent substances. More elaborate, expensive and lengthy laboratory analysis will still be necessary in order to obtain a detailed picture about a product's content. \u003cbr/\u003e              Luca Fiorani is a team member at ENEA's Diagnostic and Metrology Laboratory. He says the goal is to implement a new version of the food laser that could be put on the market. \u003cbr/\u003e              The idea is to make it lighter, portable and user-friendly so that non-scientists like food authorities could use it on the spot as they check products in grocery stores or places like fish markets. \u003cbr/\u003e              A new laser version is about three years away, Fiorani adds. But when made portable, the food laser could also be employed by food companies and food distribution chains in their food quality control tests and even help consumers as they browse through supermarkets' aisles.\u003cbr/\u003e            \u003cbr/\u003e\u003cbr/\u003e              Frascati, Italy - 11 September 2017\u003cbr/\u003e              1.
