Grape Seed Extract Reduces the Infectivity of Norovirus - HACCPEuropa

In the study, the researchers observed that under treatment with grape seed extract, at low doses, the spherically-shaped murine (mouse) norovirus-1 coat proteins clumped, and showed obvious deformation and inflation. At higher doses, the researchers saw no coat proteins, only protein debris. This provides evidence that grape seed extract could effectively damage the norovirus capsid protein, which could reduce viral binding ability and infectivity accordingly.
