1. Development and characterization of active film with omega-3 as a proposal for enrichment of butter
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

2. Effect of active antimicrobial films on the growth of pathogenic bacteria in Mantı
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 diff

3. Película biodegradable de almidón de maíz termoplástico y quitosano con actividad antimicrobiana empleada como envase activo
ABSTRACT One of the research lines related to active packaging takes into account the incorporation of antimicrobial agents such as chitosan, a polysaccharide derived from the crustaceans’ exoskeleton. However, because of chitosan high molar mass, its diffusion from the package to the food surface is restricted, so the use of oligomers is an interesting bu

4. POLÍMERO BIODEGRADÁVEL ANTIMICROBIANO ATRAVÉS DA ADITIVAÇÃO COM COMPOSTOS À BASE DE ZINCO
Antimicrobial packaging is a promising type of active packaging, which has an antimicrobial agent incorporated into the polymer matrix, capable to eliminate or inhibit deteriorating and/or pathogenic microorganisms. The zinc compounds are antimicrobial agents commonly used to confer this feature. The objective of this work was to evaluate the antimicrobial a

5. Microalgae biopeptides applied in nanofibers for the development of active packaging
Abstract This study was conducted to develop PCL nanofibers with the incorporation of microalgae biopeptides and to evaluate the stability of chicken meat cuts during storage. PCL and PCL/biopeptides nanofibers were formed by electrospinning method, and the diameters obtained were 404 and 438 nm, respectively. The tensile strength, elongation, melting temper

6. Whey protein-based films incorporated with oregano essential oil
Abstract This study aimed to prepare whey protein-based films incorporated with oregano essential oil at different concentrations, and evaluate their properties and antimicrobial activity. Films were more flexible with increasing the concentration of oregano oil and water vapor permeability was higher in the films with oregano oil. Increasing the concentrati

7. MICROESTRUTURA E PROPRIEDADES DE FILMES DE AMIDO-ÁLCOOL POLIVINÍLICO-ALGINATO ADICIONADOS DE ÓLEOS ESSENCIAIS DE COPAÍBA E CAPIM LIMÃO
AbstractFilms obtained by blends between starch and other polymers and films developed with the addition of an oil can show higher water vapor barriers and improved mechanical properties. Films with starch/PVOH/alginate were obtained by adding copaiba and lemongrass essential oils (EOs). Films without oil served as the control. The microstructure, water vapo

8. Essential oils of thyme and Rosemary in the control of Listeria monocytogenes in raw beef
This study was developed in order to evaluate two alternatives for the control of Listeria monocytogenes in raw bovine meat pieces, both based on the use of Thymus vulgaris and Rosmarinus officinalis essential oils (EOs). The antilisterial activity of different concentrations of the EOs was tested in vitro using agar dilution and disk volatilization techniqu

9. Polysaccharide-based biomaterials with antimicrobial and antioxidant properties
Active packaging is one of the responses to the recent food-borne microbial outbreaks and to the consumer’s demand for high quality food and for packaging that is more advanced and creative than what is currently offered. Moreover, with the recent increase in ecological awareness associated with the dramatic decrease in fossil resources, research has turne

12. Microbiological quality and other characteristics of refrigerated chicken meat in contact with cellulose acetate-based film incorporated with rosemary essential oil
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 o
