Due to the growing interest of consumers in the consumption of fresh products with increased shelf life, producers must provide modern and safe packaging. This is a challenge for food packaging and acts as a driving force in the development of new and improved concepts of packaging technology. The article presents the essence, types and classification of packaging as a factor influencing the choice made by the consumer. In addition, the main attention was paid to the definition of knowledge and attitudes of consumers to this type of packaging used in the food market in the food industry. From the point of view of food consumers, the most important role of packaging is to ensure food safety throughout the logistics chain, from producer to consumer. Smart packaging is packaging that is equipped with features that allow it to track the goods through the logistics chain or control the internal and external environment of the packaging, as well as communicate with the consumer. Such packaging can not only control the quality and safety of the product, but also report its condition to a potential consumer or manufacturer. The advent of intelligent packaging systems has contributed to another important change in the existing perception of packaging, as it transforms the traditional communication function of packaging into an intelligent communication function. Another solution for innovative food packaging is active packaging. Active packaging is a system that, due to chemical, physical and biological actions, actively changes the conditions inside the packaging in order to extend the shelf life and preserve the original quality and sensory properties of food. In active packaging, the product, the environment and the packaging interact, thereby increasing product quality, shelf life and durability. Reasonable and active packaging, in addition to the function of protecting the product from the reaction of external factors and attracting the attention of the customer, is aimed at informing potential buyers about the condition and quality of goods and interaction with packaged foods

Packaging of dairy products develops continuously along with advances in material technologies, which are in turn a response to demands of consumers. This article aimed to give an overview of currently available dairy packaging systems. Novel dairy packaging systems include new packaging technologies such as the modified atmosphere packaging (MAP) that is widely used nowadays, especially for dairy product like cheese. Application of edible packaging could significantly reduce the costs of cheese packaging by reducing the amount of usually required packaging material. Nanomaterials and active packaging might be useful for extending the shelf life of dairy products by reducing material permeability or negative sensory characteristics of batch processing. Forms of active packaging relevant to dairy foods include oxygen scavenging, carbon dioxide absorbers, moisture and/or flavour/odour taints absorbers; releasing compounds (carbon dioxide, ethanol, antioxidants and/or other preservatives); maintaining temperature control and/or compensating temperature changes and antimicrobial packaging. Antimicrobial packaging is gaining interest from packaging scientists and industry due to its potential for providing quality and their safety benefits. The greatest challenge from the ecological point of view is biodegradable packaging. The main challenges for low waste materials are the durability of the packaging correlated with product shelf life as well as the ecological perspective.

Active Food Packaging

The use of edible biofilms in food packaging reduces the use of petrochemical polymers that are harmful to human health, such as PE, PP, PET. The second most common biopolymer in nature, chitosan is a nontoxic, nonantigenic, biocompatible and biodegradable polymer. Considering these features, it is frequently used in food packaging applications. Increasing needs for food amount and quality canalized food ındustry to fund in new packaging techniques that improve storage life and grade of foods. Active packaging systems, one of these methods, can be designed as a sensor, antimicrobial or antimigrant in order to extend the shelf life of the food product and to inform the shelf life in possible degradation. Essential oils, which are antimicrobial environmentally friendly packaging material additives, are used due to their effective biological activities. Essential oils that have known antimicrobial properties include lavender, rosemary, mint, eucalyptus and geranium. These oils are also edible. In this study, it is aimed to produce antimicrobial, ecofriendly, edible, printable biofilm for active packaging, using chitosan and peppermint essential oil. For this purpose, chitosan biofilms containing different rates (0, 1, 2.5, 5, 10%) of peppermint essential oil were produced by solvent casting method. Surface morphology were examined by SEM. The transparency of biofilms was determined by UV spectroscopy. Antimicrobial properties of the obtained films were determined against S. aureus and E. coli. Biofilms were printed with screen printing. The color, gloss, contact angle, surface tension values of all printed and unprinted samples were examined. As a result, chitosan biofilms which are loaded with peppermint essential oil were successfully produced. Biofilms are colorless, highly transparent and have good printability. It is concluded that the amount of peppermint essential oil increased inhibitory feature against S. aureus and E. coli. When the obtained results are examined, it is determined that the printable, ecofriendly, edible biofilms can be used in active food packaging applications.

In this work, thin transparent breathable films were prepared for food packaging applications. The films were obtained by the solvent casting method from both the binary blends Pebax® MH1657 copolymer/ hydroxyl-terminated polyethylene glycol (PEGOH) and Pebax® MH1657/polyethylene glycol dimethyl ether (PEGDME) as well as the ternary blend Pebax® MH1657/PEGOH/PEGDME with a 50/50 and 37.5/62.5 PEGOH/PEGDME weight ratio for additive amounts comprised between 0 and 50 wt.%. The microstructure of these materials was investigated by differential scanning calorimetry (DSC) and wide-angle X-ray scattering (WAXS) analyses. Regardless of the PEG’s nature, for a PEG amount inferior to 30 wt.%, the Pebax® and PEG phases were totally miscible. For higher amounts, a phase separation was obtained. In the presence of PEG, a decrease in crystallinity was obtained. The effects of the nature and amount of PEG on the thermo-mechanical, hydration, and gas (CO2, O2) transport properties were investigated. A study of the film’s stability in terms of composition over time was also performed. From this work, a wide range of films could be proposed with a stable composition over time and adjustable mechanical and gas transport properties for the prolongation of the shelf-life of highly breathable fresh products.

Food packaging is not only a simple protective barrier, but a real “active” component, which is expected to preserve food quality, safety and shelf-life. Therefore, the materials used for packaging production should show peculiar features and properties. Specifically, antimicrobial packaging has recently gained great attention with respect to both social and economic impacts. In this paper, the results obtained by using a polymer material functionalized by a small synthetic peptide as “active” packaging are reported. The surface of Polyethylene Terephthalate (PET), one of the most commonly used plastic materials in food packaging, was plasma-activated and covalently bio-conjugated to a bactenecin-derivative peptide named 1018K6, previously characterized in terms of antimicrobial and antibiofilm activities. The immobilization of the peptide occurred at a high yield and no release was observed under different environmental conditions. Moreover, preliminary data clearly demonstrated that the “active” packaging was able to significantly reduce the total bacterial count together with yeast and mold spoilage in food-dairy products. Finally, the functionalized-PET polymer showed stronger efficiency in inhibiting biofilm growth, using a Listeria monocytogenes strain isolated from food products. The use of these “active” materials would greatly decrease the risk of pathogen development and increase the shelf-life in the food industry, showing a real potential against a panel of microorganisms upon exposure to fresh and stored products, high chemical stability and re-use possibility.

AbstractThe purpose of the article is to present the concept of information value of food packaging, characterize determinants of information value and present the results of own research on the identification of key information on packaging affecting purchasing decisions of food consumers. Unit packaging constituting an inherent element of food products equipment should fulfill numerous, overlapping functions, which include: protection, transport andinformation — functional, as well as ecological and promotional. One of the priority functions of product packaging (not just food) is the informative function. It is assumed that the proper selection of information encoded on the packaging should inform the consumer exhaustively, reliably and comprehensively about the packed product, its composition, nutritional values or storage conditions. Analyzing the information included on food packaging, it can be stated that entities introducing these products onto the market still show a tendency to “excessively” label the packaging (as part of optional labeling). It is therefore reasonable to specify what information is analyzed by consumers in the purchasing process and what information constitutes the information value of unit packets from the point of view of individual consumers. The above will allow identifying key determinants of the information value of packaging and may constitute valuable information for entities introducing products to trade in the field of proper selection of characters and codes of unit packets on the food market.

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.

Abstract. The article discusses the emergence of a functional literacy construct and the rediscovery of illiteracy in industrialized countries during the second half of the 20th century. It offers a short explanation of how the construct evolved over time. In addition, it explores how functional (il)literacy is conceived differently by research discourses of cognitive and neural studies, on the one hand, and by prescriptive and normative international policy documents and adult education, on the other hand. Furthermore, it analyses how literacy skills surveys such as the Level One Study (leo.) or the PIAAC may help to bridge the gap between cognitive and more practical and educational approaches to literacy, the goal being to place the functional illiteracy (FI) construct within its existing scale levels. It also sheds more light on the way in which FI can be perceived in terms of different cognitive processes and underlying components of reading. By building on the previous work of other authors and previous definitions, the article brings together different views of FI and offers a perspective for a needed operational definition of the concept, which would be an appropriate reference point for future educational, political, and scientific utilization.

Contrast-detail (C-D) curves are useful in evaluating the radiographic image quality in a global way. The objective of the present study was to obtain the C-D curves and the inverse image quality figure. Both of these parameters were used as an evaluation tool for abdominal and chest imaging protocols. The C-D curves were obtained with the phantom CDRAD 2.0 in computerized radiography and the direct radiography systems (including portable devices). The protocols were 90 and 102 kV in the range of 2 to 20 mAs for the chest and 80 kV in the range of 10 to 80 mAs for the abdomen. The incident air kerma values were evaluated with a solid state sensor. The analysis of these C-D curves help to identify which technique would allow a lower value of the entrance surface air kerma, Ke, while maintaining the image quality from the point of view of C-D detectability. The results showed that the inverse image quality figure, IQFinv, varied little throughout the range of mAs, while the value of Ke varied linearly directly with the mAs values. Also, the complete analysis of the curves indicated that there was an increase in the definition of the details with increasing mAs. It can be concluded that, in the transition phase for the use of the new receptors, it is necessary to evaluate and adjust the practised protocols to ensure, at a minimum, the same levels of the image quality, taking into account the aspects of the radiation protection of the patient.
