The article presents research on the improvement of technology of whole-muscle meat products made from pork obtained from large white breed animals, whose population in the structure of the breeding. This domestic breed of pigs was not chosen by chance, since in recent years many industrial pig farms have focused on breeding animals. It is established that dietary salt in comparison with cooking, increases such indicators as moisture-binding and water-holding abilities, increases the yield of products by 4% and reduces losses during heat treatment by 4.6%. The use of bacterial cultures in the composition of the brine contributes to the improvement of the structural-mechanical properties and quality of salted raw materials. The improved brine formulation helps to maintain high organoleptic characteristics and to obtain a dietary product with a balanced mineral composition.

Rice husk ash (RHA), palm oil mill effluent (POME) sludge and decanter cake can be utilized together in compost production to minimize the environmental pollution. This study aims to evaluate the role of different composition of RHA in enhancing the physicochemical properties of palm oil-based compost. The composts were prepared by mixing different composition of RHA, in the range of 0% to 30%, with 1:1 (wt/wt) weight ratio of POME sludge and decanter cake. The moisture content, water holding capacity, pH, nitrogen (N), phosphorus (P), potassium (K), silica (Si) contents, and C:N ratio of raw materials were analyzed by using CHNS and WDXRF analyzers. The composting process was conducted in compost containers for 60 days, in which the temperature and pH of the composts were monitored daily. The finished composts were analyzed for physicochemical properties as same as raw materials. For physical properties of finished composts, RHA30 had the highest moisture content and water holding capacity which was 1.9 to 23.8% (wt/wt) and 4.2 to 26.8% higher compared to other finished composts, respectively. For chemical properties, the highest N and P contents were recorded by control compost. However, for K and Si content, the elements were found to be higher in RHA10 and RHA30, respectively, compared to other finished composts. Overall, RHA, POME sludge and decanter cake combination in compost production can create a well-balanced condition for the compost to perform effectively as an organic fertilizer. The addition of 5% to 10% RHA in compost formulation made from palm oil mill wastes is suggested to achieve the desirable condition.

This study was conducted to compare the quality and sensory characteristics of spent hen and broiler in South Korea. The carcasses of spent hens and broilers that had been slaughtered 24 h before were used. The cooking yield and water holding capacity of broiler was significantly higher than that of spent hen (p < 0.05). The pH of broiler thigh was significantly higher than that of the other treatments (p < 0.05), while on the other hand spent hen breast had a lower value than other treatments (p < 0.05). The redness of the thigh of both types was more than that of the breast (p < 0.05). In contrast, the yellowness of the breast of the two types was more than that of the thigh of both types. The changes in organoleptic characteristics of broiler was higher than that of spent hen, and the aroma patterns detected using the electronic nose were markedly different in terms of the type of meat. Spent hens are generally considered to have lower consumption rates than broilers because they have a lower taste and aroma. Therefore, the results of this study suggest that processing or additives are required in the distribution method of spent hens.

This research set out to compare the physical and microstructural characteristics of kefir made of milk, colostrum, and milk-colostrum mixes at various proportions. Kefir was made by adding kefir grains to 100% milk (P0), 80% milk + 20% colostrum (P1), 60% milk + 40% colostrum (P3), 40% milk + 60% colostrum (P4), 80% milk + 20% colostrum (P5), and 100% colostrum (P6). Fermentation was allowed under room temperature for 24 hours. The characteristics observed were color values, viscosity, pH, water holding capacity (WHC), syneresis, and microstructure. The result showed that the color of kefir (L* value, lightness); (b* value, yellow-blue), (a*, red-green), and whiteness index (WI) was significantly affected by raw materials. The viscosity of kefir was also affected by the raw materials (p<0.05), in which the kefir made from a mix of 80% milk and 20% colostrum showed the highest viscosity (1524.20 m.Pa.S). However, other characteristics such as pH, WHC, and syneresis were not significantly affected by raw materials. The microstructure of kefir made from 20 to 40% colostrum showed a string and compact protein tissues, while that made from 80 to 100% colostrum showed a clumping gel and concentration dominated by protein and fat tissues.  This study demonstrated that milk kefir produced from milk-colostrum mixes posses a yellowish color (b*), low whitenes index, negative a* value, low lightness, whereas kefir made from 100% colostrum showed slightly greenish with low lightness level. Kefir with highest viscosity was produced from combined 80% milk and 20% colostrum. The microstructure of kefir produced from mixes with 40% and 60% colostrum showed a strong, tight, and compact microstructure of protein tissues.

Cherry fruit are valuable crop for technical processing, which quickly deteriorate during storage. Therefore, it is possible to extend the processing time by developing new technologies for raw materials storage and processing. Freezing is among the technologies . The purpose of the research is to assess the quality of frozen cherry fruit under their treatment with sodium alginate solutions. The objective of the study is to determine the effect of frozen cherry fruits treatment with sodium alginate solution on their physical and chemical parameters. The studies were conducted during 2016−2018 on cherries fruits of the Alpha and Memory Artemenko varieties selected at the Pomology Research Station named after L.P. Symyrenko. Cherry fruit were immersed in a 2, 3 and 5 % sodium alginate solution and kept for 5−10 minutes. They were further removed and packaged into 0.5 kg plastic bags and frozen at −24 °C, followed by storage at −18 °C. In frozen cherry fruits, the water-holding capacity for the Memory Artemenko varieties is 5.6 % and 9.5 % for Alpha , which is 2.3–2.5 % higher than the processed fruits with a solution of sodium alginate. The content of dry soluble substances in the cherry fruit varieties of Pamyat’ Artemenko and Alpha made 15.89 and 15.84 %. During the freezing, it decreased by 4.2–5.2 %. In the processed cherry fruit they were slightly less – 0.6−1.9. The content of titratable acids in the cherry fruit variety of Memory Artemenko and Alpha was 1.74 and 2.02 %. During the freezing, their content decreased by 18.8−19 %. Cherry fruit treated with sodium alginate had a smaller loss in the content of titratable acids of 8.9−16 %. The smallest losses of 8.9–9 % were in cherry fruit pre-treated with 5 % sodium alginate solution. Cherry fruit pretreatment with alginate solution before their freezing made it possible to improve the quality of cherry fruit while maintaining water-holding capacity by 2.3–2.5 %, dry soluble substances by 0.6–1.9 %, and titratable acids by 8.9–16 %, ascorbic acid − 8,1–17,4%. Key words: cherry fruit, alginate, soluble substances, acids, water-holding capacity.

Aspects for the use of regional raw materials in ground food technology require further study of functional and technological properties to be able to predict them depending on the chemical composition of raw materials and processing methods. The aim of our research was to comparatively study the chemical composition, functional-technological, rheological properties of fish raw materials, and duck meat in terms of their possible compatibility in meat-containing products. The subject of our research was representatives of the regional aquaculture Carassius gibelio and Hypophthalmichthys molitrix, as well as the meat of Muscovy duck (Cairina moschata). It has been established that the nutritional value of freshwater aquaculture objects Carassius gibelio and Hypophthalmichthys molitrix  is virtually identical in protein and fat content, making them interchangeable in terms of nutritional balance when developing the combined product. The ratio of protein and fat to water for duck meat is higher 3.54 – 4.88 times that of aquaculture, which can be used in the selection of components of the formulation of emulsified products, taking into account the nutrient balance. It has been confirmed that the addition of salt enhances water holding capacity, water binding capacity, and fat holding capacity. Water holding and water-binding capacities of minced fish are higher due to higher water levels, which, combined with the low-watering duck meat, can be predicted to create a forcemeat system with high functional-technological properties. The ability to emulsification and retain fat in the state of emulsion in minced duck meat has proved to be better, which when combined with fish minced meat can compensate for the ability to retain fat in the system of combined products. A combination of regional aquaculture with waterfowl meat will not only improve the functional and technological parameters of combined minced systems but also balance them by correcting the composition of proteins and fats.

The modern market has strict requirements for competitive products, forcing the manufacturer to implement scientific and technological progress in production, increase labor productivity and product quality, and reduce cost. The unchanged favorite on the confectionery market is sugar biscuits, it is in high demand among all groups of the population, the share of domestic products is more than 85 %. The quality and nutritional value of food products largely depend on the properties and composition of the predominant amount of raw materials, which in the production of sugar cookies are wheat flour, sugar and fat component. In order to update the technological control schemes and optimize the recipe composition of sugar cookies, depending on the type of fat component used, the influence and the relationship between the functional and technological properties of fatty products traditionally used in the production of sugar cookies (margarine, confectionery fat, milk substitute fat, palm oil), and quality characteristics of finished products (structural and mechanical, physicochemical and organoleptic indicators, rheological indicators of emulsion and dough) have been investigated. As a result of the studies, it has been found that the type of fatty products has a significant impact on the development and optimization of technological methods in relation to specific production conditions, the formation of sensory and structural characteristics of the finished product. Recommendations have been developed for optimizing the recipe composition of cookies depending on the type of fat used. In particular, it has been shown that it is advisable to use a milk fat substitute or margarine in products with a simple recipe composition, while the use of palm oil and confectionery fat is more justified in products with a rich recipe composition, in which organoleptic characteristics are formed by the presence of additional raw materials: dairy products, cocoa powder, nuts, dried fruits, etc.

The purpose of this study is to assess the tenderizing effect of plant proteolytic enzymes upon raw rabbit meat. Tests are performed on rabbit meat samples treated with papain and two vegetal sources of natural proteases (extracts of kiwifruit and ginger root). Two variants of marinade solutions are prepared from each vegetable raw materials- 50% (w/w) and 100 % (w/w), with a duration of processing 2h, 24h, and 48h. Changes in the following physicochemical characteristics of meat have been observed: pH, water-holding capacity, cooking losses and quantity of free amino acids. Differences in values of these characteristics have been observed, both between control and test samples, as well as depending of treatment duration. For meat samples marinated with papain and ginger extracts, the water-holding capacity reached to 6.74 ? 0.04 % (papain), 5.58 ? 0.09 % (variant 1) and 6.80 ? 0.11 % (variant 2) after 48 hours treatment. In rabbit meat marinated with kiwifruit extracts, a significant increase in WHC was observed at 48 hours, 3.37 ? 0.07 (variant 3) and 6.84 ? 0.11 (variant 4). The test samples also have reduced cooking losses compared to control samples. In control samples, cooking loss is increased from 13.79% (2 h) to 20.78 % (48 h). SDS-PAGE of meat samples after 48 h of treatment shows a reduction in the intensity of actin and myosin bands in all variants with papain and vegetal extracts. Electrophoretic pattern of test samples depicts proteolysis and degradation of muscle proteins.
