Net Assets

The authors closely consider the economic performance behavior of Russia’s top eight mining and processing plants over the period of a few years. Sustainability of the companies and high demand for their products in the market are highlighted. An important criterion of liquidity position of mining and processing plants (MPP is English for the Russian GOK) is the change in the net assets which have on the whole grown over the period under analysis from 38,5 to 52,8 BRub, i.e., 1.37 times. After a decline in the post-crisis period (2015–2016), the index of the net assets increased by 31 % in 2018. Inventories of all GOKs increased, and the annual average values jumped 2 times (Lebedinsky GOK–2.15 times, Mikhailovsky GOK–2.3 times, Kovdor GOK and Karelski Okatysh–2.4 time, other GOKs–1.2–1.5 times). This proves stability of the liquidity positions of the test companies. A steadily growing trend was observed in buildup of the permanent assets of GOKs: this index of the test companies was 9.6 BRub in 2011 and 22.9 BRub in 2018 (a 2.4 times growth). The highest rate growth was demonstrated by the largest GOKs: Lebedinsky (2.8 times), Stoilensky (3.4 times) and Kovdor (2.1 times). At the same time, there is a downward trend in profitability of the test GOKs, which, by the authors’ opinion, dictates the corporate governance improvement. Efficiency of the corporate governance and competitive ability of a company drastically depend on: capacity of equipment in each process stage; quality of interaction between process stages; balance of capacities of process stages; high-skilled staffing level of each link in the production chain; efficiency of management; quality of information accumulation of current data on the behavior of each production chain link.

The Ideal

During handling operations, many problems that reduce the quality of vegetables may occur. Mechanical injuries are the leading cause of postharvest losses for the pumpkin, and can take place at any point of the production chain. This study aimed at evaluating the pumpkin fruits behavior, during their ripening stages, on the values of maximum compression force for fixed deformations, and determining the proportional deformability modulus of the fruits under compression at the repose position. Fruits were harvested at 15, 30, 40, 50 and 60 days after flowering and uniaxially compressed between two parallel plates. The results allowed to conclude that both the required compression force and the proportional deformability modulus increased during the maturation course, reaching a maximum force of 1,778 N and a maximum deformation modulus of 164 MPa, after 30 days. After this period, both the maximum force and the modulus values decreased, reaching 1,514.8 N of maximum force and a modulus of 132.09 MPa, after 60 days of ripening. Over the course of a longer maturation time, the fruit firmness increased, therefore requiring an increase in the maximum load to achieve greater deformation. The ideal period for harvest and transport of 'Jacarezinho' pumpkin fruits was set from 30 to 40 days after anthesis.

Microbiological Analyses

Linseed (Linum usitatissimum L.) and fi bre hemp (Cannabis sativa L.) can be used as raw materials in various applications. In this study, microbiological quality and meteorological measurements were made during the growing seasons and harvesting periods of 2001 and 2002. The microbiological analyses were carried out with Hygicult® TPC and Y&F dipslides, and with a surface spreading method using Plate Count and Potato Dextrose agars. During the growing season of 2001 the conditions were mostly humid, whereas the growing season of 2002 was rather dry and warmer than that of 2001. The lack of water during the growing season of 2002 affected the growth of the plants. In the case of both hemp and fl ax, the mould and bacterial contents (cfu gdw-1) increased markedly at the end of the growing season of 2001. During the growing season of 2002 the increase in mould and bacterial contents was noticeable but more constant throughout the whole growing season. At the end of the growing seasons, the mould and bacteria contents were higher in 2001 than in 2002. The genera of moulds identifi ed included Cladosporium, Fusarium, Penicillium, Mucor and Alternaria. The microbiological safety should be controlled during the whole production chain, beginning with the cultivation and harvesting periods.;

Abstract In this paper I review the production of frozen vegetables and fruits from a chain perspective. I argue that the final quality of the frozen product still can be improved via (a) optimization of the complete existing production chain towards quality, and/or (b) introduction of some promising novel processing technology. For this optimization, knowledge is required how all processing steps impact the final quality. Hence, first I review physicochemical and biochemical processes underlying the final quality, such as water holding capacity, ice crystal growth and mechanical damage. Subsequently, I review how each individual processing step impacts the final quality via these fundamental physicochemical and biochemical processes. In this review of processing steps, I also review the potential of novel processing technologies. The results of our literature review are summarized via a causal network, linking processing steps, fundamental physicochemical and biochemical processes, and their correlation with final product quality. I conclude that there is room for optimization of the current production chains via matching processing times with time scales of the fundamental physicochemical and biochemical processes. Regarding novel processing technology, it is concluded in general that they are difficult to implement in the context of existing production chains. I do see the potential for novel processing technology combined with process intensification, incorporating the blanching pretreatment—but which involves quite a change of the production chain.

ABSTRACT Irrigation management is essential to promote appropriate plant growth and guarantee production and quality of the tomatoes for processing, increases the efficiency of nutrients use and contributes to ensure the sustainability of the production chain. This study was installed to evaluate productive performance of two processing tomato hybrids submitted to five water depths under drip irrigation system. Five levels of crop evapotranspiration (ETc) replacement (60%, 100%, 140%, 180% and 220%) and two tomato hybrids (BRS Sena and H 9992) were tested. The experimental design was a 5×2 factorial arranged in randomized complete block design with four replications. During the crop cycle, hybrids BRS Sena and H 9992 needed 692.20 and 418.43 mm of water, yielding 80 and 44.06 t ha-1, respectively. For both hybrids, the higher water productivity was observed when lower levels of irrigation were applied. Higher productivities and pulp yields of ‘BRS Sena’ and ‘H 9992’ were noticed when replacing 150-166% and 99-101% ETc, respectively. We observed that improving the performance of processing hybrid tomatoes is possible by adjusting irrigation levels for each hybrid according to growing conditions.

Soladoye, P. O., Shand, P. J., Aalhus, J. L., Gariépy, C. and Juárez, M. 2015. Review: Pork belly quality, bacon properties and recent consumer trends. Can. J. Anim. Sci. 95: 325–340. Several factors can affect pork belly quality and, subsequently, bacon quality. Going by the recent trends in the bacon market and bearing in mind the more choosy nature of the consuming populace, it is imperative to consider the factors that can affect or improve bacon quality, thereby sustaining the current market surge. In as much as both genetic and environmental factors have been identified as largely affecting muscle food quality, nutritional interventions also seem to be a very viable tool to improve the quality of meat and its products. Processing and storage methods can also affect bacon quality, including microbial quality, physicochemical attributes and palatability. Both objective and subjective measures have been explored in assessing belly quality, most of which use belly softness and fatty acid profile as yardsticks, whereas bacon quality has been widely assessed only subjectively in terms of fat quality and slice integrity. Although consumers’ and producers’ quality perceptions seem to be in conflict, it is the responsibility of all stakeholders in the bacon industries to come together in ensuring a balanced approach to satisfy both parties along the production chain.

ABSTRACT: Beans are popular as a protein-filled legume of high nutritional value, being one of the most planted species in the world. However, recent years have seen a decrease in the consumption of beans, owing to the time necessary to cook it domestically. Thus, it is being replaced in people’s diets by other foods. An alternative preparation that supplies modern consumers’ demands is industrially processed beans. This article aimed to provide a literature review on the processing of canned beans. Few recent studies have been performed in Brazil on this subject, as most studies have focused instead on the technological quality of dry bean grains processing. In this article industrial processing concepts and features, production unit operations, and canned beans quality standards will be discussed. These efforts are expected to contribute to the Brazilian beans production chain, and consequently to increase consumption of canned beans and the demand for industrial processing of beans in both the domestic market and future product exports.

The Relationship

The review presents the special significance of changes in the intestinal and skin microbiota in the formation of atopic dermatitis (AD) in children. AD is considered as a form of allergic pathology directly related to the state and quality of the microbiota of a growing organism. The microbiota of the skin of patients with AD is characterized by a small species diversity of bacteria; a decrease in the number of actinomycetes and proteobacteria; increased colonization of various types of staphylococci (S. aureus, S. epidermidis, S. haemolyticus, etc). The relationship between the rate of development of AD and violations of the microbiota of the skin in children is shown. The necessity of maintaining high biodiversity of the microbiota of a growing organism as a strategy for optimizing the microecology of children through the use of adaptive probiotics in a healthy microenvironment is substantiated. The restoration of the barrier function of the skin and the normalization of the composition and quality of the intestinal microbiota are determined as the most important task of the general concept of the treatment of AD, where new dermatological cosmetics and proper skin care play an important role. The possibilities of normalizing the microbiome of the affected skin areas to restore the skin barrier with the help of dry skin care cosmetics are shown.

Chilli pepper (Capsicum spp.) is an annual vegetable fruit used as a spice in almost all food and especially in all local dishes in Benin. However, it is neglected in many countries and relegated to the background which does not favor the agricultural development. As a result, its cultivation and conservation are still traditional and face many cultural and post-harvest constraints. The objective of this work is to make an investigation on the current state of the chilli pepper sector in Benin from the planting, growth, harvest until the transformation through storage and preservation. Overall, the review presents all the technical shortcomings hindering the opening of the sector on its socio-economic environment and to make recommendations for the improvement of the quality of chilli pepper sold and consumed in Benin. Thus, the results of this review indicate that there are several local varieties of chilli pepper grown in Benin belonging to three species of the Solanaceae family: Capsicum chinense (annual variety), Capsicum annuum L. (annual variety) and Capsicum frutescens (perennial variety). Its production is generally in rainfed or irrigated crops, in truck farming or on mainland. The best farming technique is the one that begins with the nursery and its success depends on the quality of the plants resulting from this stage. The best methods of storage and preservation vouching a good sanitary quality of chilli pepper are still to be promoted. The main problem encountered by the tillage of chilli peppers in Benin is its contamination by mold during its production and storage. It is therefore important to follow the technical production, storage and preservation routes, to assess the susceptibility of chilli pepper to mold at each stage and to measure the mycotoxins throughout the production chain so as to vouch the safety of chilli pepper consumers and to develop the chilli pepper sector in Benin.

The Impact

Abstract The formation and storage of man-made waste of water-soluble ores creates a global environmental problem that entails changing landscapes in mining areas and environmental degradation. The involvement of man-made waste in a closed cycle of the production and technological chain makes it possible to reduce the impact of mining and processing on the environment. The use of non-waste (low-waste) technologies, in addition to reducing the environmental burden, allows you to expand the raw material base of the enterprise by replacing the traditional components of the backfill mixture with man-made waste from mining and processing enterprises. The possibility of replacing the traditional, specially extracted aggregate in the backfill mixture with industrial waste of water-soluble ores is experimentally proved. The possibility of creating a cementless backfill mixture is proved. The possibility of replacing the cement binder with magnesium-containing slags of the Chusovsky Metallurgical Plant was confirmed. It was found that the separate activation treatment of the components of the backfill mixture has a positive effect on its rheological properties and increases the strength of the joint mass. The use of lignosulfonate improves the quality of the mixture and the resulting mass. The development of a backfill composite from man-made waste makes it possible to implement the principle of organizing mining production, which provides for the use of intermediate products in cyclic production and excludes the formation of man-made waste of water-soluble ores.
