Abstract

The aim of this study was to investigate the properties of polyethylene antimicrobial film containing niacin and limonene microcapsules in cheese process packaging. In this study microcapsules containing nisin (0.5, 1, 1.5, 2 and 2.5) and limonene (5, 7, 10, 14, 21 and 28 µg / mg) were prepared by gelation method.. After optimization, niacin and limonene microcapsules were used in polyethylene film based film formulation. After packaging cheese cheese in the film containing optimized microcapsules containing concentrations (1, 1.5 and 2 µg / mg nisin and 5, 7 and 10 µg / mg limonene), total microbial populations, mold and Yeast, Staphylococcus coagulase positive, Escherichia coli were examined on the first days of production, 20th, 40th, and 60th storage. The results were analyzed by two-way ANOVA and Duncan tests at the significant level of 0.05. During 60 days of storage, total microbial indices, mildew and yeast, Staphylococcus coagulas positive and Escherichia coli significantly decreased (p≤0.05). The results showed that treatment with Nisin containing 2 IU / mg concentration and limonene with concentration of 10 µg / mg resulted in higher quality of processed cheese during storage period and were selected as optimal treatment. © 2021 Tarbiat Modares University.
