Analysis of methods for determining the hardness of the winding shows that all existing methods require a lot of labor and time. When measuring the layer-by-layer hardness, the known methods do not allow obtaining continuous values, and in the case of measuring the hardness of packages of complex shape (conical bobbins, cops, spinning cobs, etc.), it requires a calculation using cumbersome formulas. In this case, the main difficulties arise in determining the volume of the layers of the winding, which in the general case have a complex configuration, and due to defects in the winding may have an irregular shape. Obviously, the described technique is rather cumbersome, and a lot of measurements and calculations are required to obtain a graph of the change in the winding hardness along the package radius. The construction of a graph of the change in hardness along the generatrix using a special device is generally problematic, since placement of more than three sources on the device is impossible due to the size of the meters, and the construction of the curve by three points cannot be considered satisfactory. Winding hardness is one of the most important parameters, on which many technological properties of the package depend. Indeed, with an increase in the hardness of the winding, the amount of material in the same volume increases, which makes it possible to replace packages less often, both on the machine that forms them, and at the subsequent transition. As a result, the equipment useful time increases. It was found that the hardness of the winding is closely related to its rigidity, and hence to the stability during transportation. The hardness of the winding affects the permeability of the package when it is treated with solutions. In this case, a huge role is played not only by the average value of the hardness, but also by its distribution over the layers

Pasta made from durum wheat is a widely consumed worldwide and is a healthy and convenient food. In the last two decades, there has been much research effort into improving the nutritional value of pasta by inclusion of nonconventional ingredients due to the demand by health-conscious consumers for functional foods. These ingredients can affect the technological properties of the pasta, but their health impacts are not always measured rather inferred. This review provides an overview of pasta made from durum wheat where the semolina is substituted in part with a range of ingredients (barley fractions, dietary fibre sources, fish ingredients, herbs, inulin, resistant starches, legumes, vegetables and protein extracts). Impacts on pasta technological properties and in vitro measures of phytonutrient enhancement or changes to starch digestion are included. Emphasis is on the literature that provides clinical or animal trial data on the health benefits of the functional pasta.

The objectives of this study were the selection of lactic acid bacteria (LAB) isolated from raw milk and studying their technological properties and antibacterial activities against bacteria as the cause of cattle mastitis. Biochemical and molecular identification using 16S–23S rRNA gene spacer analysis and 16S rRNA gene sequencing highlighted the presence of three species: Lactiplantibacillus plantarum, Lactococcus lactis, and Levilactobacillus brevis. The enzymatic characterization followed by the determination of technofunctional properties showed that LAB strains did not exhibit any hemolytic effect and were able to produce protease and lipase enzymes. Isolates showed very high antagonistic activity against Gram-positive and Gram-negative bacteria by producing H2O2, bacteriocin(s), and organic acid(s). APIZYM micromethod demonstrated that all selected strains are capable of producing valine arylamidase, cystine arylamidase, N-acetyl-β-glucosaminidase, and ᾳ-mannosidase. The antibiotic susceptibility assay showed that all selected strains were sensible to the majority of tested antibiotics. Based on these results, it can be concluded that the technological properties of the selected LAB allow considering their industrial use in order to formulate bioactive functional foods or drug(s).

This paper reports the development of a technology for a fat-based semi-finished product, which was used in the manufacturing of products made from butter sponge-cake batter. When combining high-oleic type oils, beeswax, and monoglyceride, the dense emulsion "oleogel" is formed, which can replace fatty products in flour products technology. The fat-based semi-finished product devised fully matches the technological functions of margarine. The expediency of using sunflower oil of high-oleic type (90.0 %) was established, as a base for the fat-based semi-finished product, as well as the rational percentage of organogelators (monoglyceride, 7 %, beeswax, 3 %), which would ensure the production of a fat-based semi-finished product for the target purpose. The feasibility of using a fat-based semi-finished product has been determined in order to solve two tasks: the introduction of a fat-based semi-finished product that contains high-oleic sunflower oil and has several functional benefits of a healthy diet. The fat-based semi-finished product devised could replace butter in the butter sponge cake technology. It was established that the use of the fat-based semi-finished product ensures the production of products from sweet dough, characterized by the highest values of specific volume and porosity. Applying the fat-based semi-finished product makes it possible to increase the yield of finished products (shrinkage decreases by 19.5 % compared to the control sample, to 18.4 %). The parameters for storing finished products from sweet dough containing the fat-based semi-finished product have been substantiated. It was determined that intensive fat release begins on day 7 of storage of finished products. After 10 days of storage, the experimental samples of sponge cakes release 2.0 times less fat than the control sample. The technology for making products from sweet dough using the fat-based semi-finished product has been developed.

Introduction. Treatment and prevention of diseases of the oral mucosa is one of the priority tasks in dentistry. In practice, antibacterial agents are often used in the complex treatment of inflammatory and destructive processes. However, long-term, uncontrolled usage of such drugs leads to numerous complications: drug tolerance, weakening of the therapeutic effect, dysbiosis of the oral cavity and gastrointestinal tract, etc. Therefore, at present, the question of search for alternative to antibiotic therapy remains open. As an alternative, it is necessary considering the usage of effective and safe herbal medicines that are easy to digest, less toxic, practically do not cause side effects and allergic reactions, and have a light regulating and normalizing effect.Aim. The aim of the present study is to develop the composition and technology of effervescent granules for the preparation of a solution for rinsing the oral cavity based on phytosubstances.Materials and methods. Dry extracts were obtained from medicinal plant materials: medicinal sage leaves, medicinal calendula flowers, yarrow herb, medicinal rhizomes and roots and astragalus woolly herb. Sodium carbonate, citric acid, anhydrous, microcrystalline cellulose – 90 (EMCOCEL®90M), povidone (Plasdone™ K-29/32) and calcium stearate were used as auxiliary substances in the granule technology. In laboratory conditions, granules based on phytoextracts were obtained by pressing wet masses. Numerical indicators of medicinal plant raw materials, technological properties of dry extracts and granules, as well as indicators of the quality of granules were determined according to the methods described in the State Pharmacopoeia XIV.Results and discussion. The numerical indicators of medicinal plant raw materials (grinding of raw materials and the content of impurities, total ash in medicinal plant materials and ash insoluble in hydrochloric acid, humidity, content of extractives) were determined and the good quality of the raw materials used in the subsequent stages of drug development was confirmed. Dry extracts from each type of medicinal plant raw materials have been developed and the technological properties of dry extracts have been determined. The composition and technology of effervescent granules by pressing wet masses has been developed. To improve the flowability and reduce the hygroscopicity of the granulated material, microcrystalline cellulose – 90 (EMCOCEL®90M) was used as a filler. To create an effervescent dosage form, citric acid and sodium bicarbonate were added to the granules. The mass for granulation was moistened with a 10% alcohol-water solution of Plasdone™ K-29/32. A draft specification of quality indicators for effervescent granules based on phytoextracts is proposed.Conclusion. In the course of the research work, the numerical indicators of medicinal plant raw materials were determined and its quality was confirmed, which made it possible to use it for further production of dry extracts. The extraction conditions were selected for each type of raw material, dry extracts were developed, and quality indicators were determined in accordance with the requirements of the State Pharmacopoeia XIV. Excipients were selected taking into account the properties of dry extracts, the composition and technology of effervescent granules based on phytoextracts was developed, a draft specification for effervescent granules was proposed in accordance with the requirements of the State Pharmacopoeia XIV.
