The work is devoted to studying the influence of physical-chemical and mechanical impact on the process of fat rendering in the presence of electrolyte (catholite) in order to develop an algorithm of fat extraction and obtain a high quality product with adjustable melting point. It is determined that the duration of rendering and heat treatment of raw materials have an equal effect on the index of acid number of ostrich fat. The inverse dependence on the hydrogen indicator of the water phase of the catholite, providing a decrease in the acid number of fat, is revealed. Positive dynamics on the indicator of acid number of ready product at fat extraction with pH of the catholite in the range of 10-10,5 irrespective of temperature and duration of process (acid number of fat did not exceed 0,77 mg KON/g) was established. In the course of fat rendering at the temperature of 50-55 ? and pH of the catolyte not lower than 9, it was found that the peroxide number is in the range of 1.56-1.81 mmol of active oxygen/kg, which confirms the inhibitory effect of the electrochemical environment not only on lipolysis, but also on lipid oxidative degradation. The highest yield of rendered fat was observed at the time and temperature of raw material processing, respectively, 60 minutes and 95 ?, pH of catholite is 10. The use of electro-activated liquid allowed to reduce time of fat extraction by half without significant losses in yield and quality of the finished product. With increase of pH of catolite up to 10,5 it was possible to reduce time and temperature of heatering up to 45 minutes and 75 ? correspondingly while maintaining high value of fat yield that confirms efficiency of electrolyte application and also possibility to set conditions and parameters of rendering depending on the objectives sought. Fat, rendered with the help of electro-activated liquid, does not possess toxicity at intragastric injection to laboratory animal, and also irritating and allergic effect during application on mucous membranes and skin

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

Sherry wine vinegar is a Spanish gourmet product under Protected Designation of Origin (PDO). Before a vinegar can be labeled as Sherry vinegar, the product must meet certain requirements as established by its PDO, which, in this case, means that it has been produced following the traditional solera and criadera ageing system. The quality of the vinegar is determined by many factors such as the raw material, the acetification process or the aging system. For this reason, mainly producers, but also consumers, would benefit from the employment of effective analytical tools that allow precisely determining the origin and quality of vinegar. In the present study, a total of 48 Sherry vinegar samples manufactured from three different starting wines (Palomino Fino, Moscatel, and Pedro Ximénez wine) were analyzed by Fourier-transform infrared (FT-IR) spectroscopy. The spectroscopic data were combined with unsupervised exploratory techniques such as hierarchical cluster analysis (HCA) and principal component analysis (PCA), as well as other nonparametric supervised techniques, namely, support vector machine (SVM) and random forest (RF), for the characterization of the samples. The HCA and PCA results present a clear grouping trend of the vinegar samples according to their raw materials. SVM in combination with leave-one-out cross-validation (LOOCV) successfully classified 100% of the samples, according to the type of wine used for their production. The RF method allowed selecting the most important variables to develop the characteristic fingerprint (“spectralprint”) of the vinegar samples according to their starting wine. Furthermore, the RF model reached 100% accuracy for both LOOCV and out-of-bag (OOB) sets.

This article presents the characteristics of the resource base of building sands within the three Podillya regions, the patterns of sands distribution, and proposals for increasing the extraction of raw materials . The construction sands of Podillya are confined to the Upper Cretaceous, Neogene and Anthropogenicdeposits. The decrease of the thickness of the sandy strata of the Opilsk Neogene suite in the eastern direction was observed with the simultaneous increase in the thickness of the overlapping strata of the rocks. There is no apparent correlation between the thickness of sandy interlayers and the quality of sands. The interdependence of the chemical composition of Neogene sands and the sand size module is established.The genetic predisposition for the distribution of building sands in different parts of the Podillya territory has been established. Four groups of sand deposits of different age have been identified within the Podillya regions, which contrast sharply with single deposits in the neighbouring territories.There is a very uneven distribution of explored reserves of sandy raw materials across the region and accordingly in the provision of construction sands in the different oblasts /regions of Podillya. The areas best provided with sandy raw materials are the central districts of Ternopil region and Slavutsky district of Khmelnytsky region . Sands of the Baltic stage distributed in Vinnytsia region are mostly poor in quality, clogged with clay material and require enrichment. The further development of the mineral raw material base and the prospects for increasing the production of construction sand in the Podillya regions is associated with the increase in production at the prepared deposits, the commissioning of reserve deposits, the conducting of prospecting and exploration work in the proposed potentially exploitable areas and additional exploration of individual deposits that are exploited. The research allows us to evaluate objectively the existing base of sand raw materials for various purposes in the Podillya region and to develop on this basis measures to increase it. The importance of the study is determined by the acute shortage of the raw material in most administrative districts of Khmelnytsky and Vinnytsia regions, by the growth in the volume of construction work (and accordingly the requirements for sandy raw materials) both in Podillya and in the country.

Milk is a part of many food products. In the expert assessment of the quality of raw materials, primary attention should be paid to its microbiological safety, since poisoning with dairy products is a common cause of diseases of the gastrointestinal tract. The experiment has been carried out on the base in the Teaching and Production Livestock Farm in the Federal State Budgetary Educational Institution of Higher Education “Russian State Agrarian University – Moscow Agricultural Academy named after K. A. Timiryazev” (Moscow). The purpose of the research was to improve the quality indicators of raw milk and yogurt. The method of processing raw milk, which reduces the number of potentially dangerous microorganisms in the products produced from it, has been studied. During the experiment the influence of electromagnetic radiation on organoleptic and physic and chemical parameters has been observed; the quantitative and qualitative composition of milk and yogurt microorganisms has been evaluated. The samples of raw materials had a uniform consistency without sediment and flakes, the color was milky white, and the smell was characteristic of natural cow’s milk. Electromagnetic treatment did not affect the main elements of the chemical composition of milk: the mass fraction of dry substances, fat, protein and lactose. In the experimental samples of raw milk after electromagnetic pulses treatment, the decrease in the growth rate of microorganisms including Quantity of Mesophilic Aerobic and Facultative Anaerobic Microorganisms (QMAFAnM), yeast and mold, has been noted. No bacteria of the Staphylococcus aureus and Escherichia coligroups have been found in the milk samples. The electromagnetic field had the negligible effect on the amount of lactic acid microorganisms in the raw material. During the experiment, there was no negative influence of electromagnetic radiation on the organoleptic, physic and chemical and sanitary-hygienic parameters of yogurt. The issues of ensuring the microbiological safety of raw milk have been described and the method for optimizing the sanitary and hygienic parameters of yogurt in accordance with the current requirements of regulatory documents has been suggest in the article.
