Combining intelligent and active packaging serves the dual purpose of detecting color changes in food that reflect changes in its quality and prolonging its shelf life. This study developed an intelligent and active packaging system made from the cellulose of Acetobacter xylinum and assessed its ability to detect changes in the quality and to increase shelf-life of packaged fresh beef. The properties of the intelligent packaging’s sensor and active packaging films were determined. The application of this system to fresh beef stored at room temperature (28 ± 2 °C) for 24 h was tested. The color of the bromothymol blue (BTB) solution (pH 2.75) in the indicator of the intelligent packaging system changed from orange to dark green to indicate that beef quality changed from fresh to rotten. The meat treated with the active packaging with 10% and 15% garlic extract decayed on the 16th h. In contrast, the meat treated with the active packaging without the garlic extracts rotted on the 12th h. The shift in the indicator’s color was linearly related to the total plate count (TPC), total volatile basic nitrogen (TVBN), and pH of the meat packaged using the active packaging system. Therefore, BTB solution (pH 2.75) can be used as an intelligent packaging indicator that will allow consumers to assess the quality of packaged meat easily. As an antimicrobial agent, the addition of 10–15% garlic extract to the active packaging films can help delay the spoilage of packaged beef.

Research background. Microbial contamination in food products is one of the significant causes of food spoilage and foodborne illnesses. The use of active packaging films incorporated with antimicrobial agents can be a measure to extend food quality and shelf life. Nevertheless, synthetic antimicrobial agents such as silver, copper, titanium, and zinc in the packaging films raised concerns among consumers due to toxicity issues. Experimental approach. The current study aimed to develop biodegradable gelatine-based edible films incorporated with microcapsules of Clitoria ternatea-derived anthocyanin as a natural antimicrobial agent. The impact of anthocyanin microcapsule incorporation on the morphology, thermal, mechanical, water vapor barrier, and physicochemical properties of the gelatine films were evaluated in this study. The effectiveness of the developed films against foodborne pathogens and their application for perishable food protection again microbial spoilage were also studied. Results and conclusions. The results show that incorporating anthocyanin microcapsules enhances the gelatine film physical and mechanical properties by increasing the thickness, tensile strength, Young's modulus, and elongation at break of the films. SEM analysis revealed that the films surface morphology with anthocyanin microcapsules exhibit a homogeneous and smooth surface texture compared to the control. The thermogravimetric analysis also showed a slight improvement in the thermal properties of the developed films. Agar well diffusion assay revealed that the developed films exhibit significant inhibition against a broad-spectrum of bacterium. Furthermore, the films composed of gelatine anthocyanin microcapsules significantly reduced the total viable count of microorganisms in the bean curd at the storage time interval of 12 days compared with the control films. Novelty and scientific contribution. Increasing global awareness for healthy and safe food with minimal synthetic ingredients as preservatives has sparked the search for use of antimicrobial agents of natural origins in active food packaging material. In this study, a safe and effective active packaging film was developed using the environmental friendly biopolymer, gelatine films incorporated with microcapsules of Clitoria ternatea-derived anthocyanin as a natural antimicrobial agent. This study demonstrated that such a method not only be able to improve the film physical properties but also significantly prolong the shelf life of food products from microbial spoilage.
