The research in the field of technology of gluten-free butter biscuits of functional purpose for nutrition of schoolchildren of junior and middle age using rice, millet, corn flour and carrot puree is presented. The quality indicators of biscuit dough and biscuit were investigated, the nutritional value and caloric content of the product were calculated. Experimental studies have shown that with a complete replacement of wheat flour with gluten-free flour of various types, the quality of biscuit dough and biscuit improves: the density of the dough decreases, its effective viscosity decreases, the products have a pleasant pronounced taste and aroma, the correct shape, the porosity of products and their specific volume increase. The developed sample of gluten-free sponge cake in terms of the content of potassium, magnesium, vitamins of groups B, A and E can be attributed to functional foods for schoolchildren's nutrition.

Background. Flour confectionery in Ukraine is in high demand, it’s made gluten-free mainly using corn and rice flour, rarely buckwheat. In our opinion, an inte­resting alternative to these types of flour will be to use sesame flour in the recipe and technology of gingerbread products, due to its convenience and unique taste. We have not found any research on the use of sesame flour in the technologies of gingerbread flour confectionery in available sources. The aim of this research is to scientifically substantiate and develop the techno­logy of gluten-free gingerbread with a complete replacement of wheat with sesame flour. Materials and methods. The object of research is the technology of gingerbread using gluten-free finely ground sesame flour. As a control sample, high-grade wheat flour was used for the preparation of children’s gingerbread by custard. The quality of gingerbread is determined according to DSTU 4187:2003 (State Stan­dards of Ukraine). Organoleptic evaluation of the samples was performed on a 5-point scale. The calculation of nutritional value (proteins, lipids, carbohydrates, dietary fiber), and the content of minerals is carried out according to the tables of chemical composition. Results. With the help of test doughs, it was found that in the recipe of children’s gingerbread it is possible to completely replace wheat flour with sesame and "dry perfume" (a mixture of spices) with nutmeg. According to organoleptic parameters of two types of gingerbread from wheat and sesame flour, the latter were less porous, but had a pleasant rich taste of sesame and nutmeg aroma. As a result, the identified shortcomings do not have a significant impact on the overall quality of gluten-free products. The technological scheme of preparation of "Sesame" gingerbreads with the use of sesame flour and nutmeg has been developed. The chemical composition, mineral content and energy value of control and deve­loped gingerbreads were calculated. The latter had better nutritional and biological value. Conclusion. The technology of gingerbread dough and gingerbreads with the use of sesame flour and nutmeg has been developed, which improves the organoleptic and physicochemical parameters of the new "Sesame" gingerbreads, makes their taste more expressive and enriches them with useful microelements. By replacing wheat flour with sesame, the finished products do not contain gluten and can be recommended to certain categories of consumers who suffer from diseases associated with wheat protein intolerance and allergy to it.

Актуальной тенденцией развития пищевых технологий является поиск ингредиентов для замены или снижения содержания сахара, соли и жира при одновременном увеличении содержания пищевых волокон в продукте. Исследовано влияние мальтита (М) и инулина (И) при замене сахара в рецептуре безглютенового печенья на текстуру и физические свойства теста и изделия, приготовленного на основе мучной смеси из амаранта, киноа и гречихи в соотношении 0,3 : 0,45 : 0,25 соответственно. Составлено пять образцов рецептур печенья, в которых сахар частично (50%) или полностью (100%) заменяли М и/или И. В рецептуре контрольного образца в качестве подсластителя использовали сахар. При приготовлении теста для безглютенового печенья количество воды для всех образцов было одинаковым. Установлено, что полная замена сахара М и И повышает показатели твердости, вязкости и адгезивности безглютенового теста, что затрудняет его обработку. В образцах, где 50% сахара заменяли М или сахар был полностью заменен М и И в равных количествах, липкость уменьшалась. Включение М в рецептуру безглютенового печенья существенно не повлияло на его физические свойства – диаметр, высоту, расплываемость, яркость цвета. Образцы печенья, выпеченные из теста с включением И, были темнее и тоньше, чем контрольный образец, и лучше сохраняли свои хрустящие свойства. Внесение М и И существенно не повлияло на твердость изделий, однако образцы печенья с полной заменой сахара М, с 50%-й заменой сахара И, а также содержащие М и И в равных количествах характеризовались значительной хрупкостью. При замене в рецептуре 50% сахара М или 100% сахара И получено мягкое и менее хрупкое печенье, привлекательное для потребителя. Таким образом, при полной замене сахара смесью М и И в равных количествах можно получить безглютеновое тесто и печенье с хорошей текстурой. Полная замена сахара в сочетании с использованием пищевых волокон с пребиотическими свойствами наряду с мукой псевдозлаковых культур позволяет создать полезный для здоровья продукт с потенциально более низким гликемическим индексом и сниженной калорийностью. The search for ingredients to replace or reduce the content of sugar, salt and fat while increasing the content of dietary fiber in the product is an actual trend in the development of food technologies. The influence of maltitol (M) and inulin (I) when replacing sugar in the formulation of gluten-free cookies on the texture and physical properties of the dough and the product prepared on the basis of a flour mixture of amaranth, quinoa and buckwheat in a ratio of 0.3 : 0.45 : 0.25 respectively was studied. Five samples of cookie formulations were compiled, in which sugar was partially (50%) or completely (100%) replaced by M and/or I. In the formulation of the control sample, sugar was used as a sweetener. When preparing the gluten-free cookie dough, the amount of water for all samples was the same. It was found that the complete replacement of sugar M and I increases the hardness, viscosity and adhesiveness of gluten-free dough, which makes it difficult to process it. In samples where 50% of the sugar was replaced by M or the sugar was completely replaced by M and I in equal amounts, the stickiness was reduced. Adding M to the formulation of gluten-free cookies did not significantly affect its physical properties – diameter, height, blurring, and color brightness. The cookie samples baked from the dough with the inclusion of I were darker and thinner than the control sample, and better preserved their crispy properties. The addition of M and I did not significantly affect the hardness of the products, but the samples of cookies with a complete replacement of sugar M, with a 50% replacement of sugar I, as well as containing M and I in equal quantities, were characterized by significant brittleness. When replacing 50% of the sugar M in the formulation, or 100% of the sugar I, a soft and less brittle cookie is obtained, which is attractive to the consumer. Thus, if you completely replace the sugar with a mixture of M and I in equal amounts, you can get a gluten-free dough and cookies with a good texture. Complete sugar replacement combined with the use of dietary fiber with prebiotic properties, along with the flour of pseudo-cereals, allows you to create a healthy product with a potentially lower glycemic index and reduced caloric content.

Aims: Gluten-free food (GFF) consumers reportedly have problems with the lower cooking quality of gluten-free pastas (GFPs) compared to gluten-containing pastas (GCPs).  This work is designed to compare the cooking quality of commercial GFPs and GCPs population wise for contributing to the resolution of the issue in the market.  Study Design, Materials and Methodology: Cooking quality parameters of 10 commercial GFPs (maize based and maize-rice based) and 10 commercial GCPs (semolina), namely optimum cooking time (OCT), weight increase (WI), volume increase (VI), cooking loss (CL), and their microstructures were determined. Results: GCPs had shorter OCT, higher WI and VI, and lower CL than GFPs (P < .05), representing higher cooking quality.  GCPs showed more consistent cooking quality compared to GFPs. GCPs showed more consistent cooking quality compared to GFPs.  GFPs made of maize showed higher cooking quality than GFPs made of maize and rice mixture (P < .05). When considering the microstructure, GCPs has a smooth outer surface where the gluten network provides a framework that holds embedded starch granules.  On the other hand, GFPs has a protruding surface where gelatinized starch provides a framework that holds embedded protein patches, which results poor cooking quality.  Conclusion: GCPs shows higher cooking quality compared to GFPs. They also exhibited a narrower range for cooking quality parameters indicating their more consistent behavior than those of GFPs.  GFPs made of maize showed higher cooking quality than GFPs made of maize and rice mixture.  Originality/value: To the best of the authors’ knowledge, this is the first work comparing the cooking quality of populations of commercial pastas (10 GFPs versus 10 GCPs) and embodied the issue.

Studying trust within human-robot interaction is of great importance given the social relevance of robotic agents in a variety of contexts. We investigated the acquisition, loss and restoration of trust when preschool and school-age children played with either a human or a humanoid robot in-vivo. The relationship between trust and the quality of attachment relationships, Theory of Mind, and executive function skills was also investigated. No differences were found in children’s trust in the play-partner as a function of agency (human or robot). Nevertheless, 3-years-olds showed a trend toward trusting the human more than the robot, while 7-years-olds displayed the reverse behavioral pattern, thus highlighting the developing interplay between affective and cognitive correlates of trust.

The system of indicators of quality of carbon-carbon composite material and technological operations of its production is proved in the work. As a result of the experimental studies, with respect to the existing laboratory equipment, the optimal number of cycles of saturation of the reinforcing frame with a carbon matrix is determined. It was found that to obtain a carbon-carbon composite material with a low cost and the required quality indicators, it is necessary to introduce additional parameters of the pitch melt at the impregnation stage.

The authors focus on the process of potash ore production by a mechanized method. They show that currently there are no approved procedures for assessing the performance of heading-and-winning machines operating in the conditions of potash mines. This causes difficulties in determining the field of application of heading-and-winning machines, complicates the search for implicit technical solutions for the modernisation of existing models of mining units, prohibits real-time monitoring of the stability of stope-based technological processes and makes it difficult to assess the performance of the services concerning mining enterprises. The work represents an aggregate assessment of the performance of heading-and-winning machines for potash mines by determining complex indicators describing the technological and technical levels of organising the work in stopes. Such indicators are the coefficients of productivity and energy efficiency, respectively. Experimental studies have been carried out in the conditions of the potash mine of the Verkhnekamskoye potassium-magnesium salt deposit to assess the performance of the latest and most productive Ural-20R heading-and-winning machines manufactured in Russia. Using the above methodological approaches, this paper shows that the unsatisfactory technological performance of the studied machine is due to the low productivity of the mine district transport. The average productivity coefficient was 0.29. At the same time, high values of the energy efficiency coefficient show that the productivity of the machine is on par with design conditions.

Gluten-free (GF) products, including pasta, are often characterised by nutritional deficiencies, such as scarce dietary fibre and excess of calories. Chickpea flour is increasingly being used by the food industries. Hulls, rich in dietary fibre and bioactive compounds, are discarded after milling. The aim of this work was to evaluate the quality features of short-cut GF fresh pasta added of hull (8% w/w) derived from kabuli (KH) or Apulian black (ABH) chickpeas, in comparison with control GF pasta prepared without hull. The enriched pasta, which could be labelled as “high fibre”, was characterised by a higher level of bioactive compounds and antioxidant activity than the control. ABH-enriched pasta showed the highest anthocyanins (33.37 ± 1.20 and 20.59 ± 0.11 mg/kg of cyanidin-3-O-glucoside on dry matter in raw and cooked pasta, respectively). Hull addition increased colour intensity and structural quality of GF pasta: ABH-enriched pasta had the lowest cooking loss and the highest water absorption capacity; KH-enriched pasta showed the highest firmness. No significant differences in sensory liking were found among the samples, except for “aftertaste”. Chickpea hull can be used as an innovative ingredient to produce potentially functional GF pasta, meeting the dietary needs of consumers without affecting quality.
