20 Jul 2020 --- Vitamin Bullets are microcapsules that could be used to “supercharge” the nutrients of bivalve shellfish, such as oysters, clams and mussels. Developed by the Department of Zoology at the University of Cambridge, UK, and biotechnology company BioBullets, this patented form of seafood fortification results in oysters delivering around 100 times more vitamin A and over 150 times more vitamin D than natural oysters. The Cambridge researchers flag that this avenue is “very affordable,” with the fortification costs involving manufacturing, distribution and implementation costs increasing the oyster retail price by less than 1 percent.
