The search for equivalent flavoring sugar substitutes of a non-sugar nature is an urgent direction in the development of the technology of flour confectionery products. In the course of research, a gingerbread recipe has been developed with a partial replacement of the prescription sugar with a 15 % solution of sucralose in glycerin, which most closely correspond to the organoleptic characteristics (taste, smell, texture) of traditional flour confectionery products. The results of the organoleptic evaluation of coded prototypes of gingerbread with the involvement of experts have shown that a decrease in sugar concentration by 25 % does not lead to a statistically significant change in organoleptic parameters in comparison with control samples. Substitution of more than 30 % sugar leads to an increase in the plasticity of the dough complicating the operation of the dosing mechanisms; at the same time, the taste of the products changes (these changes are noted during the tasting assessment); their consistency becomes denser. In the process of research, the stability of the quantitative and qualitative properties of gingerbread during storage has been proved. Experimental samples of gingerbread with 25 % reduced sugar content retain all the indicators established by GOST for their storage for 90 days without statistically significant changes. The decomposition of sucralose in the manufacture of the dough is 0.1 %, in the baking process - 2.6 %, during storage for 120 days - 6.7 % (of the loaded product). The developed recipe allows enterprises to expand the range of confectionery products with reduced sugar content.

Ensuring the quality of confectionery products and controlling factors affecting changes in organoleptic characteristics during storage requires studying processes that affect lipase activity, one of which is the process of moisture migration. Lipase activity, the rate of the moisture transfer process, and the change in microbiota in various parts of the model samples of raw gingerbread with fruit filling, glazed with confectionery glaze based on lauric type fats, packed in a polypropylene film 40 ?m thick in an average layer-by-layer sample were studied: top layer with glaze, filling, baked semi-finished product. Studies have shown a correlation between analytical results and organoleptic evaluation. During storage during moisture transfer, moisture migrates from the filling to the baked semi-finished product and then to the upper layer with glaze, while in all layers the mass fraction of moisture stably remains above 5%, which is higher than the value at which lipase activity is maintained. The moisture transfer rate in the top layer was 1.12, in the baked semi-finished product – 1.34 and in the filling – 7.03 g/m2·s (· 10-4). Water activity decreased, but did not reach a threshold value of 0.6 after 12 weeks of storage. At the same time, at 6-8 weeks of storage, there is an increase in the activity of water in the baked semi-finished product, which indicates the release of free moisture. Organoleptic analysis revealed a “soapy” taste, starting from the 8th week of storage, which correlates with an increase in water activity. Microbiological studies showed a significant increase in the content of QMAFAnM from 8 weeks of storage, mold growth up to 410 CFU/g was observed at 10 weeks of storage. Studies have shown a correlation of lipase activity with moisture transfer processes and microbiota growth, which requires more stringent quality control of raw materials and storage conditions to prevent lipolytic damage to flour confectionery products glazed with confectionery glaze based on lauric type fats.

The article presents the ground of developing the 50-point scale for evaluating cakes by organoleptic parameters. The aim of the article is to create the new point scale of organoleptic evaluation for using at producing organic cakes. It was established, that for today such important parameters as “flavor”, “post-flavor”, “porosity structure” are not always used at the organoleptic evaluation of cakes’ quality. The article describes the recipes of four developed cakes, produced of the organic raw materials – “Grechanyk”, based on buckwheat flour, “Zhytnytsa’, based on rye flour, “Golden amaranth”, based on amaranth flour and “Hempen delight”, based on hempen flour. For evaluating organoleptic characteristics of cakes, there was presented 50-point scale that includes evaluation of the following parameters: form, surface condition, color of crust, condition and color of crumble, porosity structure, smell, taste, flavor, post-taste, malaxation of crumble. Based on the method of expert evaluations, there were determined significance coefficients for each parameter. Thus, coefficient 0,5 was set for the parameters “porosity structure” and 1,5 for “color” and “smell”, the significance coefficient was equal 1 for a series of other parameters. The developed scale provided the following criteria of cakes evaluation: 45–50 points − "perfectly”, 40–44 points − "well", 30–39 points − "satisfactorily”, lower 30 points – “unsatisfactorily”. Based on the developed scale, the developed cakes were evaluated by the gustatory commission. All developed cakes corresponded to the mark “perfectly” by organoleptic parameters. The highest index of the quality level was inherent to the cake “Grechanyk” " – 0,99 at general sum of points for the gustatory evaluation 49,95. The cake Zhytnytsa corresponded to 0,98 by the quality level, "Hempen delight" – 0,96. The lowest quality level was detected in the cake “Golden amaranth” (0,94),that is caused by the specific taste of amaranth flour.

Важным показателем качества глазурей являются их органолептические характеристики, которые во многом зависят от комплекса свойств жировой основы, содержащей масло какао. В целях экономической выгоды актуален поиск жиров растительного происхождения для полной или частичной замены какао-масла с сохранением пищевых качеств высококачественных сортов шоколада и глазированных кондитерских изделий. Объектом исследования были кокосовое, пальмовое, пальмоядровое масла и их фракции. Исследованы содержание твердых триглицеридов при различных температурах, температура плавления, йодное число, массовая доля жирных кислот, триглицеридный состав указанных масел и их фракций, а также физико-химические показатели четырех образцов заменителей масла какао нелауринового типа промышленного производства – Akopol NH 53 (ААК, Дания), Couva 850 NH (IOI Loders Croklaan, Нидерланды), Melano NH (Fujl Oil Europe, Бельгия), Эколад 0101-36 TF (Эфко, Россия). Установлено, что аналогами отобранных промышленных образцов заменителей масла какао нелауринового типа могут быть жировые смеси на основе твердой стеариновой фракции. An important indicator of the quality of glazes is their organoleptic characteristics, which largely depend on the complex properties of the fat base containing cocoa butter. The search for vegetable fats for complete or partial replacement of cocoa butter while preserving the nutritional qualities of high-quality chocolate varieties and glazed confectionery products is relevant for economic benefit. The object of the study was coconut, palm, and palm kernel oils and their fractions. The content of solid triglycerides at various temperatures, melting point, iodine number, mass fraction of fatty acids, triglyceride composition of these oils and their fractions and the physical and chemical parameters of four samples of non-lauric alternative to cocoa butter of industrial production – Akopol NH 53 (AAK, Denmark), Couva 850 NH (IOI Loders Croklaan, Netherlands), Melano NH (Fujl Oil Europe, Belgium), Ecolad 0101-36 TF (Efko, Russia) were studied. It is established that analogues of selected industrial samples of alternative to cocoa butter of non-lauric type can be fat mixtures based on solid stearic fraction.

Most biochemical reactions involved in the wine-making process are catalyzed by enzymes. The use of enzymes of exogenous origin in wine production is due to the numerous technological and economical advantages demonstrated over time in the winemaking process. Understanding the important role played by enzymes in wine making technology contributes to the development of optimization strategies for the production process to improve the final quality of the wine. In order to accomplish this study, the influence of five oenological preparations with pectolytic and β-glucosidases enzymes types on the volatile compounds of white wines obtained from Fetească regală variety was analyzed by monitoring their evolution during the alcoholic fermentation to the final product. Wine samples have been physically and chemically analysed (pH, acidity, alcoholic strength, density, malic acid, lactic acid, sugar content, SO2, total dry extract and non-reducing extract) according to OIV Standards. Separation and identification of flavor compounds was performed using an Agilent 7890 gas chromatograph coupled to a 5975 C inert XL EI/CI MSD spectrophotometer. The organoleptic evaluation of wines was made according to a wide range of sensory descriptors. An important evolution of volatile compounds during fermentation was observed, depending on the type of enzyme administered, compared to the control sample. Enzymatic treatments did not significantly affect the physico-chemical composition of the wines obtained. The chromatic parameters of the wine samples varied according to the type of enzyme applied. The results of the study showed a significant influence of the enzymes on the organoleptic characteristics of the wines. Therefore, the aromatic quality of a wine is directly proportional to the chemical composition of the grapes and to the technology.

Исследованы микробиологические показатели рыборастительных полуфабрикатов до заморозки и через 10, 30, 60 и 90 сут хранения при температуре –(18 ± 1)°С. Объектом исследования были выработанные из филе тиляпии полуфабрикаты с добавлением овощных и крупяных ингредиентов в различных вариациях для улучшения консистенции, цвета и аромата рыборастительного продукта. Контролем служил образец полуфабриката из рыбного фарша без добавок. Проведена органолептическая оценка изделий, приготовленных из замороженных полуфабрикатов, хранившихся от 10 до 90 сут. Установлено, что количество микроорганизмов при внесении в рыбный фарш овощей и круп увеличивается за счет их специфической микрофлоры. После заморозки показатель КМАФАнМ снизился во всех образцах рыборастительных полуфабрикатов: через 10 сут – в 2 раза, через 30 сут – почти в 4 раза, через 90 сут – в 10 раз по сравнению с показателем до заморозки. Однако при хранении рыборастительных полуфабрикатов в течение 90 сут ухудшаются органолептические показатели всех изделий, приготовленных из них. Самое незначительное снижение органолептической оценки показали образцы, содержащие 30% овощей и 15% круп, самым нестабильным по органолептическим свойствам был образец полуфабриката, содержащий только добавку овощей. Таким образом, для сохранения при заморозке органолептических свойств изделия оптимальное количество внесения овощей в рецептуру рыборастительного полуфабриката – 30%, круп – 15%, Установлен оптимальный срок хранения замороженных рыборастительных полуфабрикатов – 30 сут. Microbiological parameters of fish-vegetable semi-finished products were studied before freezing and after 10, 30, 60 and 90 days of storage at a temperature of –(18 ± 1)°C. The objects of the study were semi-finished products made from tilapia fillets with the addition of vegetable and cereal ingredients in various variations to improve the consistency, color and aroma of the fish- vegetable product. The control was a sample of semi-finished fish minced meat without additives. Organoleptic evaluation of products prepared from frozen semi-finished products stored from 10 to 90 days was carried out. It was found that the number of microorganisms when introducing vegetables and cereals into minced fish increases due to their specific microflora. After freezing, the number of mesophilic aerobic and facultative-anaerobic microorganisms index decreased in all samples of fish-vegetable semi-finished products: after 10 days – 2 times, after 30 days – almost 4 times, after 90 days – 10 times compared to the indicator before freezing. However organoleptic characteristics of all products prepared from them deteriorate when storing fish-vegetable semi-finished products for 90 days the. The samples containing 30% of vegetables and 15% of cereals showed the smallest decrease in the organoleptic assessment, the sample of semi-finished products containing only vegetable additives was the most unstable in terms of organoleptic properties. Thus, to preserve the organoleptic properties of the product during freezing, the optimal amount of adding vegetables to the recipe of fish-vegetable semi-finished products is 30%, cereals – 15%. The optimal shelf life of frozen fish-vegetable semi-finished products is 30 days.

The article reflects the assessment of the quality of sour cream at home, and considers methods for determining the quality of sour cream. Organoleptic evaluation was performed for compliance with the requirements of GOST 52092-2003 " Smetana. Technical conditions " in terms of appearance, consistency, color, taste and smell. The consistency of sour cream is determined during its mixing, while evaluating the presence of a glossy appearance of sour cream. Sour cream is considered thick if it slowly drains from the whorl. The smell is determined immediately after mixing. Then we evaluate the taste. When evaluating the quality of the samples under study, it was found that the organoleptic characteristics of the samples fully comply with the requirements of the regulatory document. Analyzing the results of the experiment, we can conclude that in the first experiment, the sour cream purchased on the market was completely dissolved, and the sour cream from the store after dissolution showed small grains. And in the second experiment, the results showed that the color did not change in the sample # 2, but under # 1 it turned blue. The basis of this experiment is a qualitative chemical reaction to starch, which is used as a thickener.

Experiments have been made in the development of various new black-currant products, such as cloudy juice, juice concentrate and various freeze-dried preparations, along with a study of the effect of these different methods of preparation on the initial quality and storage properties. The quality was assessed from the stability of ascorbic acid and colour, the aroma number, and organoleptic evaluation. Storage lasted up to 8 months. It was established that the cloudiness exercised a slight protective effect on ascorbic acid. However, the instability of the cloud meant that the appearance of the cloudy juice was less attractive than that of the clear juice. No well-founded advantage of the cloudy juice could be demonstrated. Concentration proved less suitable, as there occurred harmful changes in ascorbic acid, colour and organoleptic properties. The freezing-drying method was excellent with respect to ascorbic acid and colour. In contrast, considerable losses in aroma occurred, with consequent weakening of the organoleptic properties. This method would be of advantage only in combination with aroma recovery, and solution of the financial problems involved. The results are discussed in the light of relevant literature.

The physicochemical properties of pastry and confectionery products greatly influence the aesthetic design of a cake topping, since they can be susceptible to physicochemical changes in a very short time, so maintaining a good appearance and texture of the topping becomes a challenge. Generally, cake creams deteriorate over time. The evaluation of the physicochemical properties of natural gums (arabic gum, tara gum, carrageenan, and pectin) is proposed in this work as a way to improve the physicochemical stability of butter-based cake creams (coverage creams) to maintain the initial appearance of the cream and to lengthen the separation time of their phases. For this purpose, some parameters related to the physicochemical stability of the cream, such as viscosity, density, bubble size, syneresis, volume and rheological behavior were measured. The result of the ANOVA and Tukey’s tests displayed significant differences for the measured parameters, which shows that natural gums substantially improve the stability of butter cream. The best natural gum found was the tara gum (TG) which improved viscosity 5.6 times with respect to that of the cream without gums (η¯ without gums = 15.49 Pa·s, η¯ with TG = 87.09 Pa·s), while the bubble size remained small, 1.6 times smaller compared to that of the cream without gum (BS¯) without gums = 57 μm, (BS¯) with TG = 35 μm), and the volume loss decreased two times when compared to that of the cream without gums ((ΔV¯) without gums = 1.57 cm3, (ΔV¯) with TG = 0.80 cm3). The cream with TG showed better rheology compared to that of the cream without gums (the cream without gums exhibited a plastic and thixotropic behavior, with permanent elastic deformation, while cream with TG exhibited thixotropic behavior without permanent elastic deformation). Finally, it was found that the cream with TG acquired a higher thixotropic index (TI) compared to that of the cream without gums (TI max. without gums = 17.40 y 71.78 q.u., TI max. with TG = 74.67 and 1559.90 q.u., at 4 °C and 25 °C, respectively) which demonstrates the effective contribution of cream with TG in 66.67% of the measured parameters.
