In this study, the effect of a Polylactic acid (PLA) antimicrobial biodegradable packaging activated with lysozyme by cold plasma on a pear juice and rice milk-based smoothie was investigated. The antimicrobial effect of the active innovative packaging was evaluated In-vitro and on the smoothie inoculated with Listeria monocytogenens and Lactobacillus plantarum. After a preliminary evaluation of the lysozyme release kinetics in different conditions, its influence on some smoothie quality parameters (water activity, pH, colour and microbial growth) was evaluated. In-vitro trials showed an antimicrobial activity of the activated film against different microorganisms. Inoculated smoothies packed in activated and not materials were stored at 10 and 4 °C and analysed overtime. Results showed the capability of the activated package to inhibit Listeria monocytogenes and to maintain a better and a more stable colour compared to control ones. Activated pouches showed the best antimicrobial effect on samples stored at 10 °C compared to 4 °C, difference due to the faster lysozyme release kinetic from the packaging material at the highest storage temperature. Obtained results highlight the potentiality of the biodegradable packaging activated with lysozyme to be applied successfully in food industry, to improve safety and extend shelf-life of juice-based product.

Abstract

In this study, the effect of a Polylactic acid (PLA) antimicrobial biodegradable packaging activated with lysozyme by cold plasma on a pear juice and rice milk-based smoothie was investigated. The antimicrobial effect of the active innovative packaging was evaluated In-vitro and on the smoothie inoculated with Listeria monocytogenens and Lactobacillus plantarum. After a preliminary evaluation of the lysozyme release kinetics in different conditions, its influence on some smoothie quality parameters (water activity, pH, colour and microbial growth) was evaluated. In-vitro trials showed an antimicrobial activity of the activated film against different microorganisms. Inoculated smoothies packed in activated and not materials were stored at 10 and 4 °C and analysed overtime. Results showed the capability of the activated package to inhibit Listeria monocytogenes and to maintain a better and a more stable colour compared to control ones. Activated pouches showed the best antimicrobial effect on samples stored at 10 °C compared to 4 °C, difference due to the faster lysozyme release kinetic from the packaging material at the highest storage temperature. Obtained results highlight the potentiality of the biodegradable packaging activated with lysozyme to be applied successfully in food industry, to improve safety and extend shelf-life of juice-based product.
