Antiviral effect of apple beverages.
A variety of apple beverages were tested for antiviral activity against poliovirus 1 or coxsackievirus B5. Freshly prepared apple juice was particularly antiviral, but its activity declined more readily than that of commercial juice in response to heat and storage. The component responsible for activity was located both in the pulp and skin; after ultrafiltration, activity was present in fractions greater and less than molecular weight 10,000. Virus infectivity was not restored from virus-apple juice complexes with gelatin, serum, Tween 80, or polyethylene glycol.
