Silver and ionization are used in many applications involving contact with perishable food. Their general antimicrobial activity at standard conditions (e.g. JIS Z 2801) is described in several publications. However, the specific conditions encountered in the perishable food supply chain, such as low temperatures or prevalent microorganisms are not considered in these tests. Furthermore, studies on the influence of food residuals on the rate of bactericidal activity are rare. Thus, the objective of this thesis was the assessment of antimicrobial methods with regard to their ability to reduce...
