The results of tests on the presence of yeasts and molds in cornstarch [AD ?IPOK? Zrenjanin, 2007-2008, made at the time when previous Regulations were valid] were analyzed in terms of bioindicative values of microfungi as indicators of quality and safety of raw material or final food products. Microbiological analysis was used to detect the presence of a number of microorganisms MMI-0001, and a questionnaire was designed at the Department of Public Health in Zrenjanin town (Republic of Serbia), where the anal?yses were done, regarding the microbiological tests on starch. In order to rationalize the analyses and make them more economical, several areas of product quality control (water, food, raw materials, space) were recommended either to be excluded or regarded as optional. Thus, analysis of presence of microfungi as indicators of product quality was categorized as optional. The results obtained from this research suggest a different conclusion because the bacteria in the samples indicated ?microbiologically?, namely bacteriologically, safe samples of food, while, on the contrary, the presence of some microfungi as distinct xerophilous or xerotolerant microorganisms, indicated that the food was mycologically non-safe. The obtained data are crucial for questioning the decision to exclude the earlier required (mycological) analysis of the samples (in the production of starch, or end products, etc.) and categorize such analyses in new Regulations as optional, depending on the manufacturer?s preference. Bioindicative values of microfungi as indicators of the quality of starch, clearly point to the shortsightedness of the new Regulations on food hygiene and safety, where tests on certain microorganisms (in this case, yeasts and molds) are not legally defined as mandatory, but the Law leaves manufacturers a possibility to choose (or not to choose) the testing and frequency of testing on the presence (absence) of microorganisms, which can be risky, both in the production and marketing of the finial products.

  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.

Beer Production

During the production of beer, and especially beer wort, the main wastes are spent grain and hot trub, i.e., the so-called “hot break.” Combined with yeast after fermentation, they represent the most valuable wastes. Hot trub is also one of the most valuable by-products. Studies on the chemical composition of these sediments and their rheological properties as waste products will contribute to their effective disposal and even further use as valuable pharmaceutical and cosmetic raw materials. So far, hot trub has been studied for morphology and particle distribution depending on the raw material composition and beer wort extract. However, there are no preliminary studies on the rheological properties of hot trub and hops. In particular, no attention has yet been paid to the dependence of these properties on the hop variety or different protein sources used. The aim of this study was to examine the effect of different hopping methods on hot trub viscosity and beer wort physicochemical parameters. Additionally, the hop solutions were measured at different temperatures. A microbiological analysis of hop sediments was also performed to determine the post-process survival of selected microorganisms in these wastes. For manufacturers of pumps used in the brewing industry, the most convenient material is that of the lowest viscosity. Low viscosity hot trub can be removed at lower velocities, which reduces costs and simplifies washing and transport. The sediments also had similar equilibrium viscosity values at high shear rates.

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.

Гибриды сахарной и сверхсахарной кукурузы являются хорошим сырьем для производства функциональных пищевых продуктов, в том числе диетического и детского питания. Важными показателями высокого качества этих продуктов являются повышенное содержание белка и ценного масла, незначительное количество плохо усвояемого кукурузного крахмала и высокое содержание антиоксидантов, а также отменные вкусовые качества. В работе представлены данные по оценке антиоксидантной активности большой группы новых перспективных гибридов сверхсахарной кукурузы среднеспелой группы, созданных с целью получения ценных источников сырья для консервной промышленности. Значения показателя общей антиоксидантной активности варьировали в широком интервале значений (от 31,8 % до 60,4 %, 568,4–1008 мкг/г семян), что указывает на перспективность использования этого важного биохимического параметра в селекции сверхсахарной кукурузы на качество. Hybrids of excess sugar maize are good raw material for the production of functional food products, including baby food and diet. Important indicators of high quality of these products are high protein content and a valuable oil, a small amount of poorly digestible maize starch and a high content of antioxidants, and also excellent taste qualities. The paper presents data on the evaluation of the antioxidant activity of a large group of promising new hybrids of excess sugar maize of mid-group created in order to obtain valuable raw materials for the canning industry. Index value of total antioxidant activity varied over a wide range (from 31,8 % to 60,4 %, 568,4–1,008 mg/g of seed), which indicates on promising use of this important parameter in the breeding of biochemical excess sugar maize on quality.
