Inhibition of viral attachment: Green tea extract contains catechins, which are polyphenolic compounds with antiviral properties. Catechins have been found to interfere with the attachment of norovirus particles to host cells, preventing the initial infection.
Inactivation of viral particles: Green tea extract has been shown to directly inactivate norovirus particles. Studies have demonstrated that catechins can damage the viral envelope, leading to reduced infectivity and preventing viral replication.
Enhancement of immune response: Green tea extract has immunomodulatory effects that can boost the immune system's response to viral infections. Catechins have been found to stimulate the production of immune cells, such as natural killer cells and T cells, which play a crucial role in combating viral infections.
Antioxidant activity: Green tea extract is rich in antioxidants, which can help reduce oxidative stress and protect cells from damage. Oxidative stress has been linked to increased susceptibility to viral infections, so the antioxidant properties of green tea extract may indirectly contribute to norovirus risk reduction.
By incorporating green tea extract into prepared foods, manufacturers can potentially create products with antiviral properties that could help reduce the risk of norovirus infection when consumed as part of a balanced diet. However, it's important to note that while green tea extract may have beneficial effects, proper food handling practices and good hygiene remain essential for preventing norovirus transmission.
