Документ Physico-chemical and rheological indicators of meat pates with corn starch suspensions prepared with electrochemically activated water(2023) Marynin, Andriy; Shpak, Vladyslav; Pasichnyi, Vladyslav; Sviatnenko, Roman; Shubina, YevgeniaThe aim of the study was to determine the influence of electrochemically activated water application on the rheological properties of corn starch suspensions and pates prepared with them. Corn starch suspensions were prepared on artesian water, which was activated by electrochemical treatment on a diaphragm electrolyzer. Physico-chemical characteristics of electrochemically activated water were determined using a Palintest 7500 photometer. Morphological studies of starch granules were carried out by scanning electron microscopy, and granulometric composition was determined by laser diffraction method. The rheological indicatorss of starch suspensions and pates were studied using a Kinexus Pro+ rheometer. The physico-chemical characteristics of electrochemically activated water except pH met the requirements of the European Parliament and Council Directive on the quality of water intended for human consumption. The water absorption capacity of starch when preparing its suspensions on a catholyte (obtained by passing a direct electric current through water in the cathode chamber of an electrolyzer) decreased by 26%, and when prepared on an anolyte (obtained in the process of water oxidation reactions on the anode) increased by 18%. The moisture holding capacity of hydrated starch decreased by 10% when using catholyte, and increased by 36% when using anolyte. Electrochemically activated water had a significant effect on the rheological characteristics of starch suspensions: with an increase in the percentage of complex shear strain, the shear stress increased proportionally for samples of suspensions made on electrochemically activated water. The viscoelastic properties of starch suspensions prepared using electrochemically activated water both at 25 ℃ and at 68 ℃ tended towards an ideally elastic gel, that is, they had more elastic structure than the control samples. Under the action of shear deformation, the elastic properties were lost, while the suspensions acquired viscosity (phase angle values increased). The maximum value of the moisture binding capacity of pates was observed when using a starch suspension prepared on anolyte. The best values of rheological characteristics of pates were obtained when using starch suspension with 2% starch prepared on anolyte. Electrochemically activated water had a significant effect on the physicochemical and rheological properties of semi-finished products, in particular corn starch suspensions, and pates prepared with them, and contributed to better structuring of the studied food systems.Документ Determining the Nutritional Value and Quality Indicators of Meat-Containing Bread Made With Hemp Seeds Flour (Cannabis sativa L.)(2021) Bozhko, Nataliia; Pasichnyi, Vasyl; Tischenko, Vasil; Marynin, Andriy; Shubina, Yevgenia; Strashynskyi, IgorMeat-containing bread with the use of hemp flour has been devised, with the subsequent assessment of its physical and chemical, sensory properties involving the study into the technological indicators of new products. Three experimental formulations for meat-containing bread were developed, which included semi-fat pork, poultry, mechanically deboned turkey, pumpkin pulp, and 8, 10, 12 % of hemp flour. A meat-containing bread from combined raw materials was adopted as control. All samples were evaluated taking into consideration their physical and chemical, technological, and sensory characteristics. It has been proven that the addition of hemp flour to the formulation improved the consumer value of products by increasing the content of protein, fat, and minerals. It was found that the protein content in the developed products was 18.03‒19.53 g/100 g, which is 3.21‒11.80 % higher than that of the analog. The fat content increased by 17.84–56.83 %, which also led to an increase in the calorie content of products. It has been experimentally confirmed that the introduction of hemp flour into bread's minced meat improves the functional and technological indicators of model meat systems. An increase in water-binding capacity was observed, by 13.46‒22.15 %; in water-holding capacity, by 10.34‒21.43 %; in fat-holding capacity, by 17.2‒26.9 %. The combination of semi-fat pork, poultry, mechanically deboned turkey, and hemp flour increases the ductility of the minced meat while reducing the shear stress, contributes to the good forming properties of the minced meat. The sensory analysis of the prototypes showed their high consumer value. The organoleptic assessment and sensory analysis of the prototypes demonstrated high consumer properties of the manufactured products, which makes it possible to recommend them for inclusion in the diets of various segments of the population.Документ The quality characteristics of sausage prepared from different ratios of fish and duck meat(2021) Bozhko, Nataliia; Tischenko, Vasyl; Pasichnyi, Vasyl; Shubina, Yevgenia; Kyselov, Oleksandr; Marynin, Andriy; Strashynskyi, IgorThe article aims to determine the effect of combining duck meat (Anas platyrhynchos) and freshwater fish (Hypophthalmichthys molitrix) on the quality (nutritional value, functional and technological properties, sensory attributes) of meat-containing semi-smoked sausages. The optimal version of the recipe with the highest quality indicators of semismoked meat sausages with duck meat and freshwater aquaculture was determined. It was found that the protein content of meat-containing, semi-smoked sausages with different ratios of duck and fish meat was 17.90% – 21.34% higher than that of the analog. A sample containing 50% duck and 30% fish has an ideal protein: fat ratio of 1:1. The following high functional properties of model minced experimental semi-smoked sausages were established: up to 72.75% moisture, water binding capacity of up to 71.47%, and water holding capacity of up to 60.60%. A comparative analysis of the rheological properties of minced meat showed that increasing the proportion of duck meat in minced meat modelling systems improves the strength of the system and increases shear stress. The addition of fish raw materials improves the elasticity of meatcontaining systems. The optimal ratio of duck and fish is 50:30 for plastic and easily minced mince system. Combining duck meat with raw fish increases the stability of the emulsion to 74.8%. Analysis of the sensory parameters of the experimental sausages confirmed that the best ratio of duck to freshwater fish is 50:30.
