Almost 800 years after farmers in the village of Gouda in Holland first brought a creamy new cheese to market, scientists in Germany say they have cracked the secret of Gouda's good taste. They have identified the key protein subunits, or peptides, responsible for the complex, long-lasting flavor of the popular cheese.

That discovery could lead to development of more flavorful cheeses and other dairy products. Their study is in the current issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.

Thomas Hofmann, Simone Toelstede and Andreas Dunkel note that the scientists have tried for years to pinpoint the natural molecules responsible for the long-lasting taste and wonderful texture of Gouda cheese. It develops during the aging or ripening stage, with aged Gouda more full and complex, with longer-lasting flavor, than the younger version. Cheese lovers prize this characteristic taste, known as the "kokumi sensation."

The scientists solved the age-old mystery by applying a molecular sensory science approach. It combined mass spectroscopy and other high-tech analytical instruments and sophisticated sensory tools to identify six gamma-glutamyl peptides that appear to be mainly responsible for the kokumi sensation in Gouda. This knowledge could be used to enhance the flavor of dairy products by technological means, the researchers say.

Deep Sea 'mushroom' Could Be Early Branch on Tree of Life

Reuters - Innovations Video Online (Oct. 24, 2014) Miniature deep sea animals discovered off the Australian coast almost three decades ago are puzzling scientists, who say the organisms have proved impossible to categorise. Academics at the Natural History of Denmark have appealed to the world scientific community for help, saying that further information on Dendrogramma enigmatica and Dendrogramma discoides could answer key evolutionary questions.
