Description
Maíra Otoni Silva and three colleagues model how ultraviolet light kills two germs in donor human milk, in a 2025 paper. Milk banks need safe ways to clear bacteria such as Escherichia coli and Listeria without cooking away the milk's value. The team tested a batch UV-C system and varied stirring, starting temperature, and milk solids.
Strong stirring mattered most, because UV light barely penetrates milk and stirring keeps bringing germs into the lit zone. At high stirring speeds, the doses needed for deep germ reduction fell several-fold. Starting temperature affected only the Escherichia coli results. Solids content interacted with stirring in the prediction models. The team fitted first-order models to the kill curves. They conclude the batch system shows real promise for milk bank processing, with agitation as the key design lever.
