Contamination Problem

Meat and fish smoked products, widely produced nowadays, occupy a permanent place in the mass diet. The consumption of smoked meat is estimated by FAO at 15.6 million tons in 2019 (+40 % growth over the past ten years). This is due to the increased incomes of consumers in many countries, which made meat and fish smoked products, once classified as "premium" delicacies, more accessible to the majority. There has been a shortage of high-quality raw materials, which, combined with a highly competitive food market, forces manufacturers to reduce their costs by using non-traditional raw materials. The latter leads to increased use of processing raw materials with smoke to effectively mask individual defects in taste, appearance and consistency of products. As a result, there is a carcinogenic contamination problem because of polyaromatic hydrocarbons (PAHs) presented in the smoke and smoking liquids, and the growth of cancer. PAHs are formed as a result of pyrolysis of wood during smoke generation at temperatures above 450-480 °C. Currently used smoke generators and schemes for cleaning smoke from PAHs are not effective enough, so they do not eliminate the main cause of PAH formation, uncontrolled pyrolysis. The principal solution to the problem is to develop methods and equipment for producing smoke at temperatures below carcinogenic peaks. A successful solution is the method for producing smoke with an infrared power supply, implemented in the design of IR smoke generator (IRSG). The device allows to reliably maintain the pyrolysis temperature of wood below 450 °C. The effectiveness of the method and apparatus is confirmed by studies of products smoked with IR-SG, in which the content of Benzo(a)pyrene is less than 0.0002 mcg/kg, which is lower than the maximum permissible concentrations of this compound in food.

The present article is based on the review of the current patent, scientific and technical sources. It summarizes the main types of smoke generators currently used in the meat and fish industry of the Russian Federation. The classification of smoke-generators on the basic attributes characterizing their technological and ecological efficiency is offered. Advantages and disadvantages of modern apparatuses for obtaining smoke are considered. The problem of contamination of food products with polyaromatic hydrocarbons (PAHs) during smoke smoking is reviewed. The main reason for the formation of this negative technological effect (pyrolysis of wood fuel in uncontrolled temperature conditions in the overwhelming majority of smoke generators and thermal chambers of different design) is pointed. The article substantiates the high urgency of improving the methods of obtaining carcinogenic free smoke compounds and devices on the basis of the analysis of constructions of domestic and foreign smoke generators and thermal chambers with the option of smoke generation, operated at food enterprises of the Russian Federation. Description of the method of smoke production with the use of infrared heating is given for the infrared smoke generator of Murmansk State Technical University as an example of successful solution of the problem mentioned in the article.

International food trade is growing due to an increase in effective demand and an increase in population. In recent years, trade relations between China and Russia have been developing dynamically. Meanwhile, China has a more active trade policy and a well-developed institutional structure for export regulation. In 2019, a decrease in Russian exports is generally noted, however, there is a steady growth trend in the sale of food and agricultural raw materials. The volume of export of processed food and agricultural products increased by 1.5 times. The legal and regulatory framework for Russian agricultural exports has changed significantly over the past three years. The priority role is given to government regulation. The development of agricultural exports has set the task of expanding the geography of sales markets. The Chinese food market for our country is becoming an object of special attention; in 2019 alone, Russia increased the volume of supplies in value terms by 41%. Meanwhile, there is potential for further increasing food supplies. Russia has not yet become a key partner for China, giving way to Japan, the United States and Korea. Further improvement is required in terms of the institutional, financial and credit, information and analytical system for promoting agricultural exports with the active participation of the state.

Phenol–formaldehyde (PF) resin continues to dominate the resin industry more than 100 years after its first synthesis. Its versatile properties such as thermal stability, chemical resistance, fire resistance, and dimensional stability make it a suitable material for a wide range of applications. PF resins have been used in the wood industry as adhesives, in paints and coatings, and in the aerospace, construction, and building industries as composites and foams. Currently, petroleum is the key source of raw materials used in manufacturing PF resin. However, increasing environmental pollution and fossil fuel depletion have driven industries to seek sustainable alternatives to petroleum based raw materials. Over the past decade, researchers have replaced phenol and formaldehyde with sustainable materials such as lignin, tannin, cardanol, hydroxymethylfurfural, and glyoxal to produce bio-based PF resin. Several synthesis modifications are currently under investigation towards improving the properties of bio-based phenolic resin. This review discusses recent developments in the synthesis of PF resins, particularly those created from sustainable raw material substitutes, and modifications applied to the synthetic route in order to improve the mechanical properties.

Elderly Consumers

The past few years have seen significant demographic changes in most regions, including an increased elderly population. Subsequently, elderly citizens comprise an important market segment of consumers, with the food industry one of the most affected areas in this context. However, food market managers previously believed that elderly consumers’ needs were stereotyped in nature. The lack of focus on this sector, therefore, left elderly consumers as an untapped market, without realizing the financial independence of this segment regarding their nutrition. This research will attempt to provide the key determinant factors on elderly consumers’ behavior related to food. For that purpose, a complete literature review of more than 123 papers regarding these concepts has been carried out. Once analyzed, we highlight the common insights to give clear guidance for supermarket managers and food manufacturers to have a better knowledge of the reasons behind elderly people’s food acquisitions.

Food Market

The COVID-19 pandemic has set new challenges for the HoReCa industry. Lockdowns have coincided with and strongly impacted the industrial transformation processes that have been taking place for a decade. Among the most important HoReCa transition processes are those related to the rapid growth of the delivery-food market and ordering meals via internet platforms. The new delivery-food market requires not only the development of specific distribution channels, but also the introduction of appropriate, very specific food packaging. Food packaging and its functionality are defined by the administrative requirements and standards applicable to materials that have contact with food and principally through the prism of the ecological disaster caused by enormous amounts of plastic waste, mainly attributed to the food packaging. To meet environmental and administrative requirements, new technologies to produce food packaging materials are emerging, ensuring product functionality, low environmental impact, biodegradability, and potential for composting of the final product. However, predominantly, the obtained product should keep the nutritional value of food and protect it against changes in color or shape. Current social transformation has a significant impact on the food packaging sector, on one hand creating a new lifestyle for society all over the world, and on the other, a growing awareness of the negative impact of humans on the environment and increasing responsibility for the planet. The COVID-19 pandemic has highlighted the need to develop a circular economy based on the paradigm of shortening distribution channels, using local raw materials, limiting the consumption of raw materials, energy, water, and above all, minimizing waste production throughout the life cycle of products, all of which are in line with the idea of low-carbon development.

This paper deals with the relation between statistical analysis as applied in economic inquiry and history as written or interpreted by economic historians. Although both these branches of economic study derive from the same body of raw materials of inquiry—the recordable past and present of economic society—each has developed in comparative isolation from the other. Statistical economists have failed to utilize adequately the contributions that economic historians have made to our knowledge of the past; and historians have rarely employed either the analytical tools or the basic theoretical hypotheses of statistical research. It is the thesis of this essay that such failure to effect a close interrelation between historical approach and statistical analysis needs to be corrected in the light of the final goal of economic study.

In 2003, ITC responded to the high level of obsolete inventory by shifting risk from finished products to manufacturing and raw materials. This required that their supply chain be much more flexible and responsive than it was in the past. By 2006, changes in the supply chain that included moving manufacturing in-house improved flexibility and responsiveness. Obsolete inventory was significantly reduced and the company was much better at matching supply and demand. Cost, however, continued to be higher than that at third parties. The company had to decide on the appropriate tradeoff between cost and responsiveness when structuring its supply chain.The case illustrates how Wills has changed its supply chain to become more flexible and responsive. This change, however, has come at a cost. The case requires the students to analyze the tradeoff between cost and responsiveness/flexibility to decide on an appropriate level of flexibility/responsiveness. The case also requires the student to understand the relative value of increased flexibility versus increased responsiveness.

<p>The structural engineering community has a strong responsibility to contribute to a more efficient use of natural resources. Nowadays the construction industry is by far the most resource intense industry sector, approximately 40-50% of all primary raw materials are used, which raises the question about the architects and engineer’s accountability. In this context and as a result of the Paris Climate agreement the Dutch government defined the program “Nederland Circulair in 2050”, which states the ambition to use 50% less primary materials in 2030 and to have a full circular economy in 2050.</p><p>One possible approach to achieve these ambitious goals is the application of renewable, bio-based materials in the built environment and to replace traditional, typically cement-based, materials. Already in the past natural building materials, such as timber and bamboo have been used widely, but in recent years new materials came up and provide new opportunities to be used in the construction industry. The authors explored various alternatives, such as hemp and flax fibres, mycelium and lignin-based fibres for composite materials, which will be described with various experimental and realised case studies.</p>

In the studies carried out within the scope of geopolitical discipline, the expression "geography is destiny" is frequently used and it is claimed that geography has unchangeable, irreversible qualities and the policies implemented are shaped through this assumption. This assumption ignores the humanitarian interventions over the geography and makes it difficult to understand the results produced by these interventions at both regional and global level. Similarly, the dynamic nature of international relations reveals new actors in the international system in times of bounce and collapse, and the borders that expand or narrow with each transformation can differentiate the geopolitical view with new sovereign countries. In the historical process, transportation accessibility, trade, search for raw materials, security and alliance relations have caused the same geography to be interpreted differently in different periods. This situation also applies to the geography of Turkey had been the homeland of empires. The developments in the Middle East over the past two decades has created a sensitivity in the relations between Turkey and the West, especially the United States. Competing interests with the EU and the US in the Middle East and the Eastern Mediterranean, has necessitated a reassessment of Turkey's geography.
