- ДокументAccelerated diagnostics of regulated microbial contaminants on specific sites of their genetic toxicity(2018) Pylypenko, L.; Pylypenko, I.; Savchak, Ye.Priority methods and methodology of accelerated molecular genetic diagnosis of bacillary pathogens of food poisoning and food spoilage based on polymerase chain reaction (PCR) are developed. The introduction of the priority methods for monitoring the hygienic safety of food will allow ensuring the food security of Ukraine, increasing the competitiveness of domestic producers in the world market, and protecting the country’s gene pool.
- ДокументAllowance for the deformation of the drop surface on the evaporation process(2018) Bushmanov, V. M.; Kogut, V. E.; Khmelnuk, M. G.; Gihareva, N. V.There are a number of problems for the solution, which need to solve the problem of evaporation of liquid droplets. This problem has been solved many times in various ways. However, these solutions use certain assumptions: the drops are solid inelastic spheres, there is no coagulation, deformation of the drop. Because of what the quality of calculation suffers and there can be a difference in calculations and experimental data. In order to increase the quality of calculations, we have attempted to add corrections to the calculations that correct certain shortcomings. The evaporation of the drop is affected by a number of factors. Among them, the properties of substances between which the exchange takes place such as the density of surface tension, heat capacity, as well as their temperatures and relative velocities of the media. The droplet, when moving through the atmosphere, experiences friction against the air, which causes the liquid to move inside the drop.

- ДокументApplication of quantitative analytical organoleptic method of analysis for determination of fruit juices adulteration(2008) Bocharova, O.The artificial aromatization of juices leads to the increse of the absolute values of the intencity of odour and aromatic taste and to the lowering of the difference between them. That alliws using of quantitative method of organoleptic analysis for determination of fruit juices adulteration.
- ДокументApplications of microwave fields in food technology: processing, preservation and extraction(2019) Terziev, S.; Usef Alhuri; Levtrynska, Yu.Microwave radiation, as a method of heat supplying, is not so far widely used in food industry. However, this method is promising because of the moisture present in food products, which is heated extremely intense. A number of scientific studies confirm that microwave radiation significantly intensifies processes of dehydration and extraction. This study presents the results of using MWAE – the microwave assisted extraction, – in the production of coffee, rosehips, medicinal herbs and other extracts. The dependencies of the extraction kinetics, thermograms and results of the study of obtained extracts qualitative parameters are presented. Different types of extraction units were used for different products: open vessel type, closed vessel type, operating at atmospheric and at reduced pressure. The extracting from ground coffee shows high values of mass transfer coefficients: [5.8, ... 8,8∙10-8] m/s, which indicates a high degree of the process intensification in comparison with methods of battery extraction. The process temperature did not exceed 100 °C, so there are no cellulose hydrolysis processes, which reduce the quality of the coffee extract. An extractor of a closed type was used for extracting from rose hips. The extraction was carried out under reduced pressure. Analysis of the obtained extract showed a high content of vitamin C and beta-carotene, compared with the extracts obtained in the thermostat.

- ДокументBiomonitoring as a method for assessing the toxicity of the environment of urban ecosystems(2019) Rogachko, Ye.; Kovalenko, I.The chronic toxicity of chemicals in the samples of street dust aqueous solutions from the leaves of Carolina poplar trees in different areas of the city, which differed in the proximity of the location of the highway, was determined. In the biotesting, Daphnia magna Straus crustaceans, which are highly sensitive to environmental pollution by heavy metal ions, oil products, etc., were used as test objects. The results of studies of dust samples that were taken from leaves directly on the road showed acute lethal toxicity of dust.
