Upstream Foods Develops Cultivated Salmon Fat to Improve Taste of Alt Seafood
Dutch startup Upstream Foods is developing cultivated salmon fat that could be used to give plant-based seafood the same flavor and mouthfeel as conventional fish. The fat is made by taking cells from living fish via a biopsy and using them to produce stem cells. These stem cells can then become fat cells, multiplying many times in a bioreactor so that one sample can produce a large quantity of cultivated fat. Finally, the cells are combined with a plant-based matrix. While the technology is already used in the pharmaceutical industry, it is not yet widely used in food production. Upstream Foods is currently operating from the Wageningen University and Research campus, but is searching for a larger lab to allow it to combine food and …
