This review presents some applications of proteomics and selected spectroscopic methods to validate certain aspects of seafood traceability. After a general introduction to traceability and the initial applications of proteomics to authenticate traceability information, it addresses the application of proteomics to trace seafood exposure to some increasingly abundant emergent health hazards with the potential to indicate the geographic/environmental origin, such as microplastics, triclosan and human medicinal and recreational drugs. Thereafter, it shows the application of vibrational spectroscopy (Fourier-Transform Infrared Spectroscopy (FTIR) and Fourier-Transform Raman Spectroscopy (FT Raman)) and Low Field Nuclear Magnetic Resonance (LF-NMR) relaxometry to discriminate frozen fish from thawed fish and to estimate the time and temperature history of frozen fillets by monitoring protein modifications induced by processing and storage. The review concludes indicating near future trends in the application of these techniques to ensure seafood safety and traceability.

Dramatical changes in society’s infrastructure require new conceptual approaches towards the research of socioeconomic phenomena. Nowadays, environment surrounding people experience qualitative changes; it has become possible to use full information on the history of objects. It is essential to develop a conceptual framework enabling to thoroughly describe the interaction of an individual and a socioeconomic environment that is changed by digital technologies. In this article, it is suggested to use the concept of socioeconomic technology in the context of exploration of digitalization processes. These include the Internet of things, big data processing, widespread implementation of personal tools to process and share information etc. The concept of socioeconomic technology allows tying up new technologies with the needs of an individual and society as well as with phenomena emerging in socioeconomic infrastructure. The suggested approach may be used at the development and implementation of the Internet of things, of global communication infrastructure, of technologies for processing and storage of data, and for the research of other aspects of society’s digitalization. Today it is possible to research different directions for the development of consumption sphere and technologies taking into account the emergence of virtual properties of objects. Virtual properties result for example in multiple ways to implement things, in the possibility to store and use the full history of major objects surrounding an individual. Conceptual framework suggested in this article allows holistically addressing the issues of commercial efficiency and socioeconomic management in the age of digitalization.

Species Being

For most starch-containing foods, the physical and functional properties can be traced to characteristic molecular species being present, their interactions with each other, and modifications caused by environmental conditions (moisture, temperature, shear) during processing and storage. In the present paper, the chemistry and physical chemistry of starch are discussed with an emphasis on how structure (molecular and supermolecular) and composition influence the functionality of this polysaccharide. New experimental findings brought forward on structure indicate that this polymeric carbohydrate is found in various metastable states, depending on the thermomechanical history of the product. Even more important to processing and quality attributes of starch products is the recognition that the dynamics of the supermolecular structure and interactions between starch and other food constituents are governed by the mobility of the amorphous phase of each particular system. In this respect, water, acting as a plasticizer, depresses the glass transition temperature (Tg) and thereby alters the kinetics of state transformations (e.g., gelatinization, retrogradation) and reactivity of starch. The effects of water on phase transition behavior of starch as well as the underlying molecular mechanisms to the phenomena of gelatinization, gelation, retrogradation, and starch–lipid interactions are reviewed herein. Finally, consideration is given to factors affecting the digestibility of starch from the viewpoint of processing-related changes in the susceptibility of starch to α-amylase.Key words: starch, amylose, amylopectin, gelatinization, gelation, retrogradation, interactions, water, lipids, supermolecular structure, digestibility.

Identification And Quantification

Abstract Fisheries enforcement relies on visual catch identification and quantification at sea or when landed. Silage (fish dissolved in acid) and fish blocks (block frozen fish) are promising methods for on-board processing and storage of low-value catches. We examined the use of non-destructive sampling and two DNA-based methods, quantitative PCR (qPCR) and metabarcoding, to assess species composition and relative abundance in industrial grade experimental silage and fish blocks. We demonstrate the ability to identify and quantify DNA from fish species in both products. qPCR analysis of small silage samples collected over 21 days detected all target control species. DNA from one species (Atlantic wolffish) was consistently overrepresented while, for three species of gadoids (Atlantic cod, haddock and whiting), the DNA content matched input tissue proportions with high accuracy. qPCR and metabarcoding of fish blocks, sampled as run-off water and exterior swabs, provided consistent species detection, with the highest variance observed in quantification from swab samples. Our analysis shows that DNA-based methods have significant potential as a tool for species identification and quantification of complex on-board-processed seafood products and are readily applicable to taxonomically and morphologically similar fish. There is, however, a need for establishing DNA/weight calibration factors for primary fisheries species.

Ice is a water that cooled below 0 °C and used for complement in drink. Ice can be found almost everywhere, including in the Wahid Hasyim Sempaja Roadside. From the preliminary test, obtained 5 samples ice cube were contaminated by Escherichia coli. The purpose of this study was to determine relationship between hygiene and sanitation with presence of Eschericia coli in ice cube of home industry at Wahid Hasyim Roadside Samarinda. This research used quantitative with survey methode. The population in this study was all of the seller in 2nd Wahid Hasyim Roadside. Sample was taken by Krejcie and Morgan so the there were 44 samples and used Cluster Random Sampling. The instruments are questionnaries, observation and laboratory test. Data analysis was carried out univariate and bivariate (using Fisher test p= 0.05). The conclusion of this study there are a relation between chosing raw material (p=0,03) and saving raw material (p=0,03) with presence of Eschericia coli. There was no relation between processing raw material into ice cube with presence of Eschericia coli (p=0,15).Advice that can be given to ice cube should maintain hygiene and sanitation of the selection, processing and storage of ice cube.

Agricultural Production Systems

The aim of the work is to assess the existing and prospective models for the development of agricultural production in Central Polesie on the basis of economic feasibility and ecological balance. The evaluation of promising agricultural production systems was carried out with the help of simulation modeling of various infrastructure options at the levels of crop and multisectoral specialization of agroecosystems. The agro-resource potential of Central Polesie is better implemented in the rotation with lupine, corn and flax dolguntsem with well-developed infrastructure, including crop, livestock units, grain processing and storage systems, feed, finished products and waste processing in the bioenergetic station. The expected income for the formation of such an infrastructure is almost 8 thousand dollars. / with a payback period of capital investments of 2-3 years.
