Defining a Criteria for the Identification of a Technique for Producing Tomato Juice

The basis of modern analysis of the quality of juice products is a matrix approach. The essence of the matrix approach is to define a series of parameters, which comprehensively characterize the composition of juices. In this regard, it is important to study the content of individual biologically active components in addition to general quality parameters in evaluation of juices. The content of individual biologically active components depends on the origin of raw materials and technology of processing.Analysis of the chemical composition of tomatoes showed that carotenoids are characteristic nutrients inherent to this particular kind of vegetables. In this regard, we propose the content of β-carotene as the most acceptable criterion for identification.We studied quality of tomato juices by organoleptic and physical-and-chemical parameters (soluble solids content, total acidity, mass fraction of pulp and β-carotene content) in order to confirm a method of production of tomato juices, namely, the method of recovery or direct pressing.The profile analysis showed that the most positive parameters were in the juices of «EosBio» TM and «Galicia» TM, which makes us assert that their production technique was direct pressing. We established that the mass fraction of soluble solids, titratable acids and pulp met the requirements in all samples. The largest mass fraction of pulp was in the juices of «Galicia» TM – 30.80 and «EosBio» TM – 24.23. This data confirms that the method of production of these juices was direct pressing.We established that the content of β-carotene in the juices of «Sandora» TM, «Rich» TM and «Sadochok» TM produced by the method of recovery was in the range of 0.24–0.32 mg/100 g. At the same time, these values were significantly higher in the juices of «Galicia» TM and «EosBio» TM produced by the method of direct pressing, they were 0.589 and 0.591 mg/100 g, respectively. Thus, we confirmed the assumption about the connection between a production method and the content of β-carotene in tomato juices. We proposed using this parameter as a marker criterion for the identification of a technique for producing tomato juice

Pseudomonas Aeruginosa as A Priority Group Representative of Bacteria with Multiple Antibiotic Resistance

The aim: the aim of the research is an analytical review of the scientific literature on Рseudomonas aeruginosa as a priority group representative of bacteria with multiple antibiotics resistance. Materials and methods. The research was conducted by the method of scientific literature open source analysis: PubMed, Elsevier, electronic resources of the National Library named after V. I. Vernadsky and others. Results. The problem of antibiotic resistance is rightly called the “apocalypse of the XXI century”. P. aeruginosa bacteria are characterized by a very high natural ability to form resistant forms to antimicrobial drugs due to the formation of specific resistance genes, the ability to resist the entry of antibiotics into the cell or remove antibiotics from the cell, and form biofilms. A characteristic feature of the epidemic and epizootic processes of P. aeruginosa, as an opportunistic ubiquitous microorganism is host-pathogenic interaction - the interaction of the pathogen with the host organism. The peculiarity of this bacterium is opportunism and long-term persistence in the body of the host and in the environment. The global trend towards the spread of antibiotic-resistant gram-negative bacteria, including P. aeruginosa, underscores the need to develop comprehensive response strategies targeting all sectors of health. Conclusions. Bacteria P. aeruginosa is classified in 1th Critical Group of the WHO list of resistant to antibiotics "priority pathogens". Among the main reasons that contribute to the emergence of resistance are irrational antibiotic therapy in both humans and animals, and the use of antibiotics as growth stimulants in animal husbandry. While more R&D is vital, alone, it cannot solve the problem. To address resistance, there must also be better prevention of infections and appropriate use of existing antibiotics in humans and animals, as well as rational use of any new antibiotics that are developed in future. New methods of combating antibiotic resistance and antibacterial substances, alternatives to antibiotics (biofilm-destroying drugs, antimicrobial peptides (AMP), bacteriophages, nanopreparations, etc.) can make a positive contribution to overcoming the multiple drug resistance of gram-negative
