Abstract

Total of 52 food additives and food materials were screened using norovirus surrogate feline calicivirus (FCV) to assess the effect of reduction against norovirus. Over 0.01% GSE (Grape Seed Extract) ethanol solution and FCV solution mixed by 1 : 1 for 1 min at room temperature, the virus infectivity were reduced <1/1,000. We had found out the effective antiviral activity in GSE containing Proanthocyanidin.
