Aquaculture Production

The supply of land-based agricultural products as aquafeed raw materials is challenged by limitations on space and water, and by environmental damage. Marine environments offer a vast opportunity for the expansion of aquaculture, including the production of feed raw materials. Besides fishmeal and fish oil, which are generated from capture fisheries, the use of marine-based feed raw materials from aquaculture production is not yet in common practice. Here, we discuss the potential of underutilized marine organisms that can be cultured by extracting nutrients from their environment and are nutritionally compatible for use as alternative feed materials in aquaculture. We identify marine organisms such as blue and green mussels, Ulva spp., and microbial floc that are nutritionally suitable as aquafeed raw material and may further act as bioremediators. However, environmental factors that affect productivity and the risk of pollutant accumulations, which would potentially reduce the safety of aquaculture products for human consumption, may pose challenges to such applications of extractive organisms. Therefore, the development of pretreatment and processing technologies will be critical for improving the nutritional quality and safety of these raw materials for aquafeed production.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.

 Udang merupakan komoditas unggulan ekspor Indonesia yang memerlukan bahan baku yang berkualitas dan aman. Untuk mendapatkan bahan baku udang yang sesuai, seluruh anggota rantai pasok harus menerapkan persyaratan jaminan mutu dan keamanan hasil perikanan sesuai Kepmen KP Nomor: 52A/KEPMEN-KP/2013. Tujuan penelitian ini adalah mengevaluasi penerapan persyaratan jaminan mutu dan keamanan hasil perikanan sepanjang rantai pasok bahan baku udang untuk unit pengolahan ikan (UPI) di Jakarta Utara. Dua UPI telah dipilih menjadi responden untuk dirunut ke hulu mengenai pemenuhan persyaratan dimaksud. Pengumpulan data dilakukan melalui survei, observasi dan wawancara kepada UPI, pengumpul/pemasok, pembudidaya dan pembenih. Analisis kesenjangan dan uji korelasi berganda digunakan untuk menilai kesesuaian penerapan persyaratan jaminan mutu dan keamanan hasil perikanan. Hasil identifikasi menunjukkan masih terdapat kesenjangan penerapan yang dilakukan oleh pembudidaya dan pengumpul/pemasok dengan standar yang ada. Tingkat kesesuaian pada pembudidaya 58% (kurang sesuai) dan pemasok 48% (tidak sesuai). Apresiasi UPI terhadap mutu dan keamanan hasil perikanan masih belum memadai, diduga karena permintaan di pasar global sangat tinggi sedangkan pasokannya tidak sesuai. Penerbitan sertifikat yang terpisah-pisah di antara rantai pasok diduga menjadi salah satu penyebab. Diperlukan perubahan strategi kebijakan dalam pelaksanaan sistem sertifikasi udang budidaya untuk ekspor yang terintegrasi dalam satu sertifikat.Shrimp is Indonesia's leading export commodity that requires quality and safe raw materials. To get appropriate shrimp raw materials, all members of the supply chain must apply the quality assurance and safety requirements of fishery products in accordance with Ministerial Decree KP Number: 52A/KEPMEN-KP/2013. This study aimed to evaluate the implementation of quality assurance and safety requirements for fishery products along the supply chain of cultured shrimp raw material suppliers for fish processing units (UPI) in North Jakarta. Two UPIs have been selected as respondents whose suppliers were evaluated regarding the fulfillment of the specified requirements. Data collection was carried out through surveys, observations, and interviews with UPI, collectors/suppliers, farmers, and breeders. Gap analysis and multiple correlation tests were used to assess the appropriateness of the implementation of quality assurance and fishery product safety requirements. The results show that gaps existed between the implementation of the requirement by farmers and suppliers compared with existing standards. The implementation level for farmers is 58% (less according) and the supplier 48% (not according). It was observed that UPI's appreciation of the quality and safety of fishery products was inadequate, allegedly because demand in the global market is very high while the supply does not meet the demand. Issuance of separate quality and safety certificates along the supply chain are believed to be one of the causes. There is a need to change the policy strategy in implementing the shrimp culture certification system for export which can be integrated into one certificate.

Propolis is a sticky resinous substance collected from buds, leaves, stems of wild plants and processed by bees, which has bactericidal properties and which they use to seal openings in the hive, polish the walls of wax cells, embalm the corpses of enemies. The analysis of research and publications gives grounds to conclude that Ukraine has not yet paid sufficient attention to the conditions of propolis production. There are no devices and equipment to improve the process of production of safe and high-quality propolis, which will meet the high requirements of regulatory acts on the quality and safety of food products and raw materials. Currently, apiaries use methods of collecting propolis, which require considerable human labor, are not economically efficient, and the resulting product does not meet the quality requirements of market operators. Therefore, there is a need to improve existing technologies for obtaining propolis, to improve sanitary-hygienic conditions of production, to increase productivity and economic efficiency, mechanization, and automation of the production process. The goal of our work was to develop a new propolis collecting device. The work was carried out as a part of the dissertation research at the Department of Standardization and Certification of Agricultural Products of the National University of Life and Environmental Sciences of Ukraine during 2020–2021. A new propolis collecting device has been designed and manufactured. The design of the device shafts and the principle of mechanical cleaning of the grids from the propolis, laid down during its development, can be used to develop highly automated lines for cleaning the grids. The use of the device in industrial apiaries in countries with tropical and subtropical climates is possible by placing the device in honeycomb storage, if available, or in a manufacturing area equipped with air conditioning. For a good cleaning of the grids with propolis using the device, it is sufficient to cool the grids at a temperature of +5 °C for 60–90 minutes, depending on the type of propolis. The device can be used at apiaries in Ukraine and other countries where the production of propolis from bee colonies is carried out using elastic grids. The use of the device ensures the production of pure propolis without mechanical impurities, which meets the requirements of current legislation. The developed device is patented, a patent № 139736 “Propolis collecting device”.

Mineral raw natural resources are not unlimited. Preservation of such non-renewable resources is the most urgent task of mankind. The development of non-waste technologies, the integrated use of secondary raw materials, which simultaneously reduces environmental damage - one of the ways to solve environmental problems. Utilization of wastes makes it possible to solve issues of environmental protection as well as resource saving. In the light of environmental requirements, building materials based on recycled materials, including cellulose-containing solid waste, have significant advantages over other traditional materials. Development of technology for obtaining new effective environmentally safe composite highly filled materials based on cellulose-containing solid household waste for the production of construction products is a rational link in solving the general problem of improving the environmental situation. In the article there are three main ways of combining gypsum binder with cellulose-containing solid household waste. Investigations were carried out on the effect of changing the ratio of cardboard / gypsum binder, specific pressing pressure, sequence of combination of components on the properties of the final product. The strength of the material was determined from the values of the flexural strength, the compression to complete destruction of the sample, and at 10% deformation. Studies have been carried out to increase moisture resistance. The results showed that the most optimal way of combining is the 2 way. The increase in moisture resistance is significantly enhanced by the action of organosilicon hydrophobisers.

ABSTRACTDecorative, polychrome ceramics from Corinth, Greece, produced during the 8th-6th centuries B.C.E. were luxury goods widely traded throughout Greece and the Mediterranean. Corinthian pottery is the first 5-color polychrome ceramic technology, having slip-glazes in distinctive white, black, red, yellow, and purple colors, and in a variety of surface finishes from glossy, to semi-matte, to matte. The firing temperature range, 925-1075°C, was determined experimentally to be to be higher than previously reported, similar to the Corinthian amphorae and other ceramic products. This firing range is higher than that of the better known, more prestigious Athenian Black-figure and Red-figure ceramics. In this study three examples of Corinthian and one example of Athenian Black-figure ceramics from the Marie Farnsworth collection at the University of Arizona were tested and compared to thirteen clays from Corinth. Analytical techniques included Fourier-transform infrared spectroscopy (FTIR), scanning-electron microscopy with energy-dispersive spectroscopy (SEM-EDS), micro-Raman spectroscopy, and wavelength-dispersive electron microprobe (EPMA with BSE-SEM).Artisans in Corinthian workshops experimented to change the colors of the slips by varying the type and amount of iron-rich raw material, as well as the composition of the clay used as a binder and the amount of flux used as a sintering aid to promote glass formation. Corinthian artisans developed not only different recipes to produce the various colors, but also they were able to control raw-material particle size and composition to produce variations in surface luster (matte, semi-matte and glossy). This research suggests that Corinthian polychrome-slip technology was based on careful control of particle processing, of compositional control of raw materials and their admixtures, and of firing temperature. The behavior or practice of adding different ratios of pigments and glass-forming fluxes to form various optical effects implies a detailed knowledge of what happens when these are heated and fired. This is a process of experimentation focused on developing a distinctive craft practice, which produced a distinctive and highly valued material. The Corinthians developed a more complex, easily recognizable, and culturally distinctive ceramic technology that was intentionally established as a cultural brand, and probably as a luxury brand of high socio-economic value. This research deepens our understanding of the complex pigment processing and firing technologies employed in the production of Corinthian ceramics.

The development of new physiologically functional food products is a prospective direction for world food products market. The inclusion of functional ingredients in food can increase the biological value of products that are already familiar to the consumer, as well as expand the range of products offered. Physiological activity of cereal’s ingredients varies widely, there are: anticancer, antiallergic, antioxidant properties, prebiotic, immunostimulating effects, etc. Moreover, the cereal’s ingredients can improve the organoleptic properties of bakery, dairy and confectionery. Cereals can be used as a prebiotics: fermentable substrates for the growth of probiotic microbiota. It is scientifically proven that grain’s nondigestible carbohydrates stimulate the growth of Lactobacillus acidophilus, L. casei, L. reuteri, L. rhamnosus, L. johnsonii, L. plantarum, Bifidobacterium longum, B. breve, B. lactis. Cereals contain water-soluble fibre, such as β-glucan and arabinoxylan, oilgosaccharides, such as xylo- and fructooligosaccharides and resistant starch, which have a wide application as prebiotic preparations. Furthermore, cereals as wheat, rye and rice contain polyphenols (benzoic and cinnamic acid derivatives) that are used both in the food industry as antioxidants, dyes, flavors of natural origin and in the compositions of physiologically functional ingredients, as well as in the pharmaceutical and cosmetic industries. Thus using cereals as a raw material for functional ingredients obtaining is a perspective in biotechnology, food and pharmaceutical industry. The modification of cereals processing technologies also will allow produce insufficiently studied prebiotic compounds, the functionality of which must be studied.

Dairy cattle breeding in Ukraine is set the task that require a radical restructuring of the industry, bringing it out of a difficult crisis situation in order to increase the production of valuable food for the population and raw materials for industry The dairy industry is a very important part of all agricultural production. The socio-economic development of the state as a whole depends on the current situation in milk production. Quality milk must meet the requirements not only for physicochemical parameters (acidity, density, mass fraction of dry matter, protein, fat), but above all be safe, ie meet the current requirements for levels of contamination with microorganisms, the number of somatic cells, maximum permissible levels toxic elements, mycotoxins, residual amounts of antimicrobials, drugs and other substances. The quality and safety of cow's milk as a raw material is a global and unresolved issue for our country. The quality of milk cannot be improved in the process of its processing, so the milk quality management system at the enterprise should be focused on high-tech processes of its production, primary processing with the use of preventive measures. At present, the issue of high-quality milk production in Ukraine is urgent. Despite the trend, the population's demand for quality dairy products is increasing every year, so the issue of increasing the productivity of the dairy herd and milk quality through the use of modern high-tech conditions of keeping and milking. Therefore, the identification of factors influencing the process of milk production in farms is aimed at solving quality and safety problems and provides information on how to better and more effectively control hazards in the overall process.

The presented study is devoted to a comparative review of the mineral raw material base of platinum group metals (PGMs) and technologies of their processing in South Africa and Russia, the largest PGM producers. Mineralogical and geochemical classification and industrial value of iron-platinum and platinum-bearing deposits are presented in this work. The paper also reviews types of PGM ore body occurrences, ore processing methods (with a special focus on flotation processes), as well as difficulties encountered by enterprises at the processing stage, as they increase recovery of the valuable components. Data on mineralogical features of PGM deposits, including the distribution of elements in the ores, are provided. The main lines of research on mineralogical features and processing of raw materials of various genesis are identified and validated.  Sulfide deposits are found to be of the highest industrial value in both countries. Such unconventional PGM sources, as black shale, dunites, chromite, low-sulfide, chromium and titanomagnetite ores, anthropogenic raw materials, etc. are considered. The main lines of research that would bring into processing non-conventional metal sources are substantiated. Analysis of new processing and metallurgical methods of PGM recovery from non-conventional and industrial raw materials is conducted; the review of existing processing technologies for platinum-bearing raw materials is carried out. Technologies that utilize modern equipment for ultrafine grinding are considered, as well as existing reagents for flotation recovery; evaluation of their selectivity in relation to platinum minerals is presented. Basing on the analysis of main technological processes of PGM ore treatment, the most efficient schemes are identified, i.e.,gravity and flotation treatment with subsequent metallurgical processing.

It is revealed that in the Volyn region in recent years the volume of agricultural exports has been increasing, which enhances the raw material orientation of the region, which in turn may lead to negative ecological and economic consequences in the future. Agricultural products produced in the region provide foreign processing enterprises with raw materials that come back to us in the form of finished products. It is substantiated that by stimulating the development of domestic agriculture, the state and local authorities for some reason pay little attention to stimulating the development of integrated productions operating on domestic agricultural raw materials. The raw material orientation of the Volyn region leads to increased extensive agricultural activities, which in turn may impair the level of ecological and economic development of the region. Given the low prices of agricultural commodities on the foreign market, it is advisable to increase the volume of exports of agricultural products with higher value added (finished products). The expediency and the basic directions of economic stimulation of creation and development of complex productions for in-depth processing of agricultural products in this region are proved. The main advantage of the creation and development of industries from the full cycle of advanced processing of natural resources is the preservation and increase of the amount of added value, which will contribute to increase of financial revenues to the budgets of territorial communities and the state budget in particular, increase of profits of processing enterprises, increase of employment of rural population, etc. It is concluded that it is necessary to develop integrated production of in-depth processing of agricultural products in the Volyn region. In this regard, additional financial resources should be attracted, first of all, to restore the fallen ones of the 1990s. or underdeveloped processing units of the agroindustrial complex of the region – flax processing, fruit and berry and canning production, vegetable drying, oil and fat production, livestock complexes for pig and cattle production, production of biofuel and food digestion.
