This paper reports the new design of an experimental bench to study the effectiveness of the positional drive control system of shut-off fittings. For research, the operating modes of the disk flap and ball valve, based on proportional elements with feedback (4–20 mA), were programmatically formed and described. The mathematical model of control ov...
We study the influence of the conditions (temperature, composition of gas mixture, and its pressure) and energy characteristics (voltage, current density, specific power of discharge) of the process of hydrogen-free nitriding in glow discharge (HNGD) on the structures and phase compositions of the nitrided layers. It is shown that, by combining the...
Background. Bee bread is one of the products of beekeeping, which is used in pre-ventive and health nutrition, which is becoming more common. The quality and nutritional properties of bee bread depend on the conditions and technology of its production.
The aim of the work was to study the quality of bee bread of a certain regional and botanical ori...
Lavender honey was studied for physicochemical and organoleptic parameters. Established high antioxidant activity of lavender honey. This confirms the prospect of using lavender honey in the food and pharmaceutical industries.
When creating meat products, one of the main indicators is the biological value of the product. The biological value of proteins depends on the degree of their assimilation, in animal proteins is greater than in vegetable. More than 90% of amino acids are absorbed from animal proteins in the intestine. An important indicator of the biological value...
Modern beekeeping industry globalization leads to an increase in competition between countries for the foreign market. The products that provide the appropriate level of safety and quality following international requirements would be able to gain a competitive advantage. Establishing a competitive advantage for honey on the world market and improv...
Homogenization is a necessary process in the production of drinking milk and most dairy products. The specific energy consumption of the most common valve homogenizers reaches 8 kW h.t-1. A promising way to reduce it is the introduction of more effective counter-jet homogenizers. The purpose of these studies is to increase the efficiency of machine...
The demand for monofloral, original, and special (functional) kinds of honey, or those with geographical indication, is forecast. At the same time, there is a need to improve the methods for determining the botanical and geographical origin of honey. The purpose of the research was to select and apply a variety of techniques for identifying the bot...
The only effective method of identification of beekeeping products by botanical and
geographical origin is to study the specificity of pollen grains in the composition of the said products. Identification of pollen grains by morphological characteristics and their percentage in the product allows to establish a botanical honey variety (black locust...
В Україні недостатньо повно розкрита наукова інформація щодо
біологічно-активних властивостей меду, особливо монофлорних сортів.
Насамперед, це пов’язано, із відсутністю потреби контролювати показники,
що зумовлюють біологічну активність продуктів згідно вимог чинного
законодавства (окрім показника діастази та проліну). Особливе занепокоєння виклик...
Вивчення класифікаційних ознак монофлорного бджолиного обніжжя (морфологія обніжки за видом пилконосних рослин, ботанічне походження, період сезону одержання, гомогенність, поліфлорність, сформованість пилкової грудочки), які формують безпечність та якість продукту, знаходиться на початковому
етапі і потребують продовження та поглиблення наукової д...
Centrifugal and vibrational technological effects are among the main approaches to intensify the process of plant raw materials hydrolysis for pectin extraction. With the impulse intensification of such a process, it is possible not only to increase its efficiency, but also to achieve the compactness of the equipment, reduce the cost of electricity...
Development and introduction of high quality gluten-free products is one of the priorities of food industry. Feasibility of producing gluten-free steamed bread based on rice and corn flour using flaxseed, sunflower, sorghum and quinoa flour additives is proved in the article. Recommended ratios of flours are established: Frc:Ffs 95:5, Frc:Fsn 95:5,...
The purpose of the work was to apply of the DPPH stable chromogen radical method for determining the antioxidant activity of beekeeping products. Product samples were selected in view of botanical origin of bee colonies in different regions of Ukraine. The antioxidant activity was determined by a spectrophotometric method with a stable DPPH chromog...
Basic requirements criteria, which must be met by honey for free movement in the world market are set by a number of regulatory documents, the key ones in Ukraine – DSTU 4497: 2005 «Natural honey. Specifications", Order of the Ministry of Agrarian Policy No. 330 “On approval of honey requirements” of 19.06.2019 and Directive 2001/110/EC. The latter...
The article investigates the classification features, biological activity, organoleptic, physicochemical indicators and biological activity of the bee pollen monofloral and polyfloral obtained from bees kept under identical climatic and geographical conditions during flowering of Acer spp. Significant differences were found in the content of protei...
Homogenization, which is used in the technological schemes of production of most dairy products, is the most energy-intensive of the processes of mechanical processing of milk. One promising way to increase the energy efficiency of homogenization is to use separate homogenization and to use a little-researched stream homogenizer with separate cream...
The article is devoted to the study of the influence of hydrocolloids and animal protein concentrates on the formation of the foam-like structure of gluten-free non-yeast dough as the main factor for bread quality formation. The use of CMC in a concentration of 0.5% is found to be appropriate. The bread volume increases to 236 cm3.100g-1 in compari...
The increase in natural cheese production has brought issues related to ensuring the production of high-quality competitive products to the fore. The development of the cheese market requires constant improvement of the existing methods of production and the search for new technological solutions, which will allow us to counterbalance the low quali...
