Zusammenfassung:Active packaging based on a release of silver ions (Ag+) has become a focus of increasing interest. However, applications are rare for beverages in particular, and the question remains whether the amount for antimicrobial effectiveness is below the migration limit of 0.05 mg Ag/kg food proposed by the EFSA. Experiments were performed using E. coli (106 cfu/mL) in distilled water and Z. bailii (
