| ABSTRACT Edible films are an alternative to synthetic materials used for packaging foods. The aim of this study was to develop and characterize films made from cassava starch, freeze-dried acai and glycerol. The films were characterized for thickness, water vapor permeability, water solubility, anthocyanins, antioxidant capacity and mechanical properties. The results indicated a rich edible film in anthocyanins with considerable antioxidant capacity (150.70 micromol Trolox), which can extend the commercial validity of the packaged food and meets the growing demand for biodegradable packaging that tends to reduce the environmental impact. The addition results in a significant effect on the polymer matrix reducing the water solubility and water activity. The... |

| Antimicrobial active packaging delays or inhibits microorganism growth in packed products, and it can be used in a variety of food systems. The objective of the present research was to develop packaging incorporated with natural antimicrobial agents (active film). The effects of the active film on the spoilage, pathogenic microorganism counts, pH and color of the refrigerated chicken breast cuts were analyzed. Cellulose acetate-based active films incorporating two concentrations (20% and 50%, v/w) of rosemary (Rosmarinus officinalis L.) essential oil were manufactured and placed in contact with the chicken breast cuts for six days. An analysis of variance and mean comparison tests (Tukey's test, p<0.05) were performed on the results. The films that... |

| Abstract Active food packaging aims to interact with food in order to improve nutritional, sensory, physicochemical or microbiological properties of the food products. The aim of this work was to development and characterization of active film with omega-3 and flavored with oregano essential oil for butter. It was produced three films: control (T1), active films added with 25% of ω-3 fatty acid and 5% of oregano essential oil (T2) and active film added with 40% fatty acid ω-3 and 5% essential oil of oregano (T3). Physical, mechanical and structural films properties were evaluated. The addition of fish oils and essential oregano did not change neither films color nor thickness in relation of control film. However, it reduced energy at break (J) and maximum... |

| Abstract The current study assessed antimicrobial films for use in active food packaging. Mantı, a tortellini-like Turkish food, was packaged with antimicrobial films to extend refrigerated storage time at 4 °C. Polycaprolactone (PCL) was separately incorporated with cinnamaldehyde (CNMA) and pomegranate methanolic extract (PME) to form antimicrobial diffusion films for use against two common food-poisoning bacteria, Escherichia coli and Staphylococcus aureus, and the mantı pieces were separately inoculated with 5 log concentrations of both types of bacteria. The films and mantı were then inserted in polyethylene bags, which were filled with 100% N2 gas and monitored at 4 °C for 28 days. The results clearly show that both a low temperature storage (4 °C)... |
