Whiskey webs—the web-like pattern that forms when drops of whiskey dry up—might be used to identify counterfeit American whiskey, according to a study published in ACS Nano.
The researchers explained that when droplets of a complex mixture evaporate, the nonvolatile components that remain may form various patterns. This phenomenon is referred to as the “coffee ring effect,” and it is something that scientists have studied for quite some time. The pattern depends on what the liquid is and what its components are. Previous research has shown that when diluted drops of various brands of American whiskeys dried on a glass surface, they formed web patterns, according to an American Chemical Society press release.
The current study went further into the characteristics of the whiskey webs and, through digital image analysis, found that each of the whiskey webs from the various brands of American whiskeys was unique. “In summary, the results reported here show that whiskeys are chemically complex liquids whose chemical profiles not only distinguish each product but are also responsible for the uniqueness of each product-specific pattern of deposits from drying droplets,” wrote the researchers. They added that the method to analyze the distinct web patterns “could be used for sample analysis and counterfeit identification.”
The dangers of a high-sodium diet have been well documented, but a new technology devised by scientists from Washington State University could help reduce sodium in processed foods while retaining taste and texture.
A study found that people who drank beverages that contained the low-calorie sweetener sucralose did experience metabolic problems and issues with neural responses but only when the beverage was formulated with both sucralose and a tasteless sugar (maltodextrin).
