The advancement of active packaging technology has contributed to the need for customer assurance of the quality and protection of fresh foods and agricultural products. An example of active packaging to maintain food quality and improve product protection is the use of antimicrobial pads. Antimicrobial pads are a type of active packaging that releases active agents into the headspace food packaging in order to prevent, inhibit or destroy the growth of microorganisms.. Antimicrobial pads are very easy to apply to food products by placing them on the bottom of the product or inserting them into the packaging material. This literature study discusses the characterization of cellulose as a major component in the manufacture of pads, techniques for the incorporation of antimicrobial compounds into pads, and suitable applications for the inhibition of microorganisms in food products. Apart from that, this literature study also discusses the advantages and disadvantages of antimicrobial pads as active packs.

Service Lifetime

Plastic packagings are widely used for several food products. Considering the relatively short service lifetime of this application, it is important to perceive in the search of eco-friendly alternatives to this market, such as polymers from renewable sources, as thermoplastic starch and “green” polyethylene. The incorporation of an antibacterial agent to the packaging can extend food shelf life. Camellia sinensis is a plant with known antibacterial properties used in the preparation of “green tea.” In the present work, green tea was incorporated to a blend of cassava thermoplastic starch and high-density polyethylene (HDPE) by melt extrusion, aiming application as active packaging. Films were obtained by thermopressing and characterized through infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy and tensile tests. Their antibacterial properties were evaluated against Staphylococcus aureus and Escherichia coli. The results indicated that the material developed has potential for food packaging applications. Moreover, the methodology applied for green tea incorporation in the Starch/HDPE films can be extended for many extracts from natural components, contributing to the advancement of research in the development of active packaging for food products. To the best of our knowledge, no previous work studied the properties of starch/HDPE blend with green tea.

<p>Labels are an integral part of a product. Observing the labels on the packaging, especially food products is considered very important to do. However, the label of food packaging products receives less attention from consumers. Therefore, the public is required to be more ingenious in observing the label of food packaging products to avoid food security problems which have adverse health effects. The purpose of this study was to map the results of research on label reading behavior. The design of this study was a literature study of research results that can be accessed via the internet. The results showed that the behavior of reading food product labels was done before buying the product (Aulawi 2005; Susanto 2008; Kumalasari and Sjafei 2012). From the frequency of reading nutrition labels, it could be found out that 42.5 percent of consumers sometimes read and 30.2 percent often read food packaging labels (Andrias 2016). Of the 52 studies, 17 studies have shown that women often read more and notice label attributes on food product packaging. The most commonly read consumer label (Figure 3) was the kosher logo and nutritional value. Food products that are usually labeled are packaged foods. Nutrition and health claims are considered as a means of education for consumers - 14 percent to know new information and 86 percent of consumers decided to read the labels because of the outside factors, such as advertising, internet, or at school.</p>

Packaging is an integral part of food products, allowing the preservation of their quality. It plays an important role, protecting the packed product from external conditions, maintaining food quality, and improving properties of the packaged food during storage. Nevertheless, commonly used packaging based on synthetic non-biodegradable polymers causes serious environmental pollution. Consequently, numerous recent studies have focused on the development of biodegradable packaging materials based on biopolymers. In addition, biopolymers may be classified as active packaging materials, since they have the ability to carry different active substances. This review presents the latest updates on the use of silver nanoparticles in packaging materials based on biopolymers. Silver nanoparticles have become an interesting component of biodegradable biopolymers, mainly due to their antimicrobial properties that allow the development of active food packaging materials to prolong the shelf life of food products. Furthermore, incorporation of silver nanoparticles into biopolymers may lead to the development of materials with improved physical-mechanical properties.

At the level of the gastrointestinal (GI) tract exists a consortium of living microorganisms like bacteria, fungi, protozoa and viruses, which represent the intestinal microbiota. This term, microbiota, comes from Greek, where ‘bios’ means ‘life’ and nowadays this is the right word to use, even if in the older literature the authors used the term microflora with the same meaning (Suchodolski, 2016). In order to describe the intestinal microbiota, there are more methods available, each of them having advantages and disadvantages. The aim of this literature study was to compare the data available regarding each method used for assessing the intestinal microbiota. Among the five methods available in the present to assess the intestinal microbiota, none of them is considered a gold standard. There are available cultural and non-cultural methods, each of them having the purpose to describe the intestinal resident bacterial populations. The most commonly used methods for characterization of the intestinal microbiota are represented by FISH- Fluorescence in situ hybridization, qPCR- quantitative real-time PCR, NGS- next-generation sequencing (e.g. 454- pyrosequencing, Illumine) and Metagenomics (shotgun sequencing of genomic DNA). In this review we made a comparison between the methods available for assessing the intestinal microbiota, showing that in the present there is not a golden standard for this and that the methods used have advantages and disadvantages.

Recent Trends

Antimicrobial active packaging has emerged as an effective technology to reduce microbial growth in food products increasing both their shelf-life and microbial safety for the consumer while maintaining their quality and sensorial properties. In the last years, a great effort has been made to develop more efficient, long-lasting and eco-friendly antimicrobial materials by improving the performance of the incorporated antimicrobial substances. With this purpose, more effective antimicrobial compounds of natural origin such as bacteriocins, bacteriophages and essential oils have been preferred over synthetic ones and new encapsulation strategies such as emulsions, core-shell nanofibres, cyclodextrins and liposomes among others, have been applied in order to protect these antimicrobials from degradation or volatilization while trying to enable a more controlled release and sustained antimicrobial action. On that account, this article provides an overview of the types of antimicrobials agents used and the most recent trends on the strategies used to encapsulate the antimicrobial agents for their stable inclusion in the packaging materials. Moreover, a thorough discussion regarding the benefits of each encapsulation technology as well as their application in food products is presented.

Ukraine’s European integration is a multilevel, dynamic, and long process that has a complex, sometimes dramatic evolution and depends on many internal and external factors. Ukraine has favorable geographical, climatic, resource and other prerequisites for rural development, so it is potentially able to become a country with priority agricultural development and one of the main suppliers to world markets of environmentally friendly food products. However, today the problem of inconsistency between the level of development of the Ukrainian agricultural sector and rural areas in general at the world level and the standards of the EU countries remains unresolved. The prerequisites for Ukraine’s integration into the EU are analyzed, considering the advantages and disadvantages of this process for the country’s agricultural market. The necessity of transition to the investment and innovation model of development of this market was proved. Optimization of the development of all sectors of the agricultural market should become a significant direction for improving the management of innovative financing. The article considers the current state of development of the agri-food market in the foreign economic activity of Ukraine. The assessment of the level of competitiveness of agricultural products is summarized. Factors influencing the improvement of competitive positions of agricultural products in the domestic and foreign markets are proposed. Global trends indicate that Ukraine can gain a lasting push for development and even become a world leader, becoming a breadwinner for almost the whole world. The adoption of EU norms and standards in Ukraine, together with duty-free trade, should attract investors who want to introduce the latest technologies into the country’s economy. This will help turn Ukraine’s economy into an exporter of value-added products, and exports of raw materials will be a thing of the past. These global changes would have to be accompanied by a qualitatively new steps to create conditions for the liberalization of markets. This should also apply to markets for agricultural products and food products. In this way, we can expect success only if we increase the competitiveness of agricultural products. And this, in turn, can only be realized in conditions of innovative development.

Establishing direct communication with the brain through physical interfaces is a fundamental strategy to investigate brain function. Starting with the patch-clamp technique in the seventies, neuroscience has moved from detailed characterization of ionic channels to the analysis of single neurons and, more recently, microcircuits in brain neuronal networks. Development of new biohybrid probes with electrodes for recording and stimulating neurons in the living animal is a natural consequence of this trend. The recent introduction of optogenetic stimulation and advanced high-resolution large-scale electrical recording approaches demonstrates this need. Brain implants for real-time neurophysiology are also opening new avenues for neuroprosthetics to restore brain function after injury or in neurological disorders. This chapter provides an overview on existing and emergent neurophysiology technologies with particular focus on those intended to interface neuronal microcircuits in vivo. Chemical, electrical, and optogenetic-based interfaces are presented, with an analysis of advantages and disadvantages of the different technical approaches.

Specific Influence

The environmental problem generated by the massive consumption of plastics makes necessary the developing of biodegradable antimicrobial materials that can extend food shelf-life without having a negative impact on the environment. The current situation regarding the availability of biodegradable food packaging materials has been analysed, as well as different studies where antimicrobial compounds have been incorporated into the polymer matrix to control the growth of pathogenic or spoilage bacteria. Thus, the antimicrobial activity of active films based on different biodegradable polymers and antimicrobial compounds has been discussed. Likewise, relevant information on biodegradation studies carried out with different biopolymers in different environments (compost, soil, aquatic), and the effect of some antimicrobials on this behavior, are reviewed. In most of the studies, no relevant effect of the incorporated antimicrobials on the degradation of the polymer were observed, but some antimicrobials can delay the process. The changes in biodegradation pattern due to the presence of the antimicrobial are attributed to its influence on the microorganism population responsible for the process. More studies are required to know the specific influence of the antimicrobial compounds on the biodegradation behavior of polymers in different environments. No studies have been carried out or marine media to this end.

The purpose of this study is to characterize Lampung iron sand and to conduct preliminary experiments on the TiO2 synthesis which can be used for the manufacturing of functional food packaging. The iron sand from South Lampung Regency, Lampung Province that will be utilized as raw material. The experiment was initiated by sieving the iron sand on 80, 100, 150, 200 and 325 mesh sieves. Analysis using X-Ray Fluorescence (XRF) to determine the element content and X-Ray Diffraction (XRD) to observe the mineralization of the iron sand was conducted. The experiment was carried out through the stages of leaching, precipitation, and calcination. Roasting was applied firstly by putting the iron sand into the muffle furnace for 5 hours at a temperature of 700°C. Followed by leaching using HCl for 48 hours and heated at 105°C with a stirring speed of 300 rpm. The leaching solution was filtered with filtrate and solid residue as products. The solid residue was then leached using 10% H2O2 solution. The leached filtrate was heated at 105°C for 40 minutes resulting TiO2 precipitates (powder). Further, the powder was calcined and characterized. Characterization of raw material using XRF shows the major elements of Fe, Ti, Mg, Si, Al and Ca. The highest Ti content is found in mesh 200 with 9.6%, while iron content is about 80.7%. While from the XRD analysis, it shows five mineral types namely magnetite (Fe3O4), Rhodonite (Mn, Fe, Mg, Ca) SiO3, Quart (SiO2), Ilmenite (FeOTiO2) and Rutile (TiO2). The preliminary experiment showed that the Ti content in the synthesized TiO2 powder is 21.2%. The purity of TiO2 is low due to the presence of Fe metal which is dissolved during leaching, so that prior to precipitation purification is needed to remove impurities such as iron and other metals.
