Why Does This Cheese Taste So Gouda?
Scientists in Germany combined mass spectrometry and other analytical instruments and sensory tools to identify six gamma-glutamyl peptides that appear to be responsible for the complex, long-lasting flavor of Gouda cheese.
Scientists in Germany combined mass spectrometry and other analytical instruments and sensory tools to identify six gamma-glutamyl peptides that appear to be responsible for the complex, long-lasting flavor of Gouda cheese. They compared 4-week-old Gouda to a Gouda that had been aged 44 weeks, which had a more intense “kokumi sensation,” or heartiness, when sampled by a taste panel. The six peptides were present in much greater quantities in the aged cheese, accounting for its richer flavor. Because the 4-week-old cheese lacked this intense kokumi sensation, the researchers concluded that the six peptides develop during the ripening process. According to the researchers, their discovery could lead to the development of more flavorful cheeses and other dairy products by technological means.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
