“…To overcome this drawback, many works have explored developing the active packaging systems with considering the retaining of these active agents in the polymer media and having control over their release for a specified time [14][15][16]. Moreover, different processing techniques such as solvent casting [17][18][19], encapsulation [20,21], electrospinning [22][23][24], and supercritical CO 2 impregnation [25,26] have been studied which are not the techniques suitable for industrial scales. Melting extrusion and compression molding are the most popular used techniques for the incorporation of active agents in the wide range of commercial polymers [26].…”

The integration of essential oils (EOs) into polymers to endow antimicrobial properties has received a lot of attention. EOs are remarkable in that they have broad antimicrobial activity from a natural source while also being volatile. Their volatility, on the other hand, makes high-temperature processing techniques difficult to incorporate into polymers. In this study, active films based on low-density polyethylene (LDPE) and limonene essential oil (LEO) were prepared and characterized. Before incorporation of LEO into LDPE, vacuum pulling method was used to load the LEO into five different mineral carriers. All Carrier-LEO complexes were added into LDPE using melt compounding. The goal is to analyze the potential use of these formulations to achieve prolonged antimicrobial film packaging. The halloysite nanotubes (HNTs), kaolinite (Kao), mesoporous silica nanoparticles (MSNs), zinc oxide nanoparticles (ZnONPs), and molecular sieve type 4A (Z4A) were used as mineral carriers for limonene. The functional characterizations including mechanical, thermal, optical, barrier, and antimicrobial properties as well as limonene release behavior from the LDPE composite films were investigated. As expected, free limonene molecules acted as a plasticizer in the LDPE matrix. Thermogravimetric analysis (TGA) showed 20-25% of the initial limonene content was retained against thermal degradation in compounding and film making steps and its release from the films was efficiently delayed. A decrease in optical and oxygen barrier properties, as well as elastic modulus and tensile strength, was obtained for all developed films compared with neat LDPE. Significant antibacterial activities of the films were observed against Escherichia coli DH5-Alpha (E. coli) as a model gram-negative bacterial species. Moreover, the obtained results and the short-term and long-term release studies indicated that both HNTs and the MSNs due to their strong synergistic interactions with limonene exhibited sustained release profiles of limonene from LDPE films. Thus, these new active polymer composites present promising features in controlling microbial contamination, rendering them as excellent candidates in active packaging applications.

“…Para que práticas inadequadas de manipulação não ocorram durante a produção e processamento dos alimentos, as empresas devem investir em treinamentos para os manipuladores, no intuito de gerar conhecimento e consciência sobre os hábitos de trabalho (OLIVEIRA, 2020). A capacitação profissional consiste em treinar os funcionários quanto a contaminantes alimentares, DTA's, manipulação higiênica dos (BPF), conforme sugere a RDC n°216, de 15 de setembro de 2004 (BRASIL, 2004).…”

“…Some authors have tried to study the effect of volatile compounds incorporation by the casting method. Following this line, cashew gum (CG) and gelatin (G) films, at a weight ratio of 5.0 CG/5.0 G and 10 wt% glycerol in relation to the total weight, were produced by incorporating ferulic acid (1 wt%) as a cross-linking agent and citral (10 wt%) from lemon grass essential oil for bread packaging [ 86 ]. The experimental packaging provided six additional days of preservation to packed bread in comparison with the 3 days for the bread in commercial packaging.…”

In the last years, many of the research studies in the packaging industry have been focused on food active packaging in order to develop new materials capable of retaining the active agent in the polymeric matrix and controlling its release into food, which is not easy in many cases due to the high volatility of the chemical compounds, as well as their ease of diffusion within polymeric matrices. This review presents a complete revision of the studies that have been carried out on the incorporation of volatile compounds to food packaging applications. We provide an overview of the type of volatile compounds used in active food packaging and the most recent trends in the strategies used to incorporate them into different polymeric matrices. Moreover, a thorough discussion regarding the main factors affecting the retention capacity and controlled release of volatile compounds from active food packaging is presented.
