Foie gras is one of the most controversial delicacies in the world. The main complaint from animal rights activists regarding its production is related to the force-feeding of geese and ducks. However, researcher and culinary enthusiast Thomas Vilgis has proposed an ethical alternative.
In the journal Physics of Fluids, he and his colleagues described a method for producing foie gras without the force-feeding of birds. The scientists used lipases — enzymes found in the bodies of ducks and geese that are involved in fat breakdown. With their help, they processed the liver and fat, achieving a texture and flavor similar to the traditional delicacy.
The recipe turned out to be quite simple: the liver and fat are taken from the bird, then treated with lipases, mixed, and sterilized. As a result, a product is obtained that is visually and taste-wise indistinguishable from classic foie gras, but does not require cruel production methods.
Vilgis has already filed a patent application and is looking for partners to expand production. Additionally, he expressed a willingness to collaborate with other researchers to further improve the taste and aroma of the dish.
