Biochemical Characteristics

Background: Studies were carried out on two breeds of pigs - Pietrain (P), and Kemerovo (K), contrasting in composition of carcasses, and their hybrids. Objective: The purpose of this work was to establish the characteristics of the composition of lipids of intramuscular fat (IMF), back fat and serum, organoleptic qualities in animals of these breeds. Methods: Animals of 10 individuals in each group were fed on a standard feed and slaughtered with a live weight of 95-100 kg. The quality of carcasses, the biochemical characteristics of blood, the composition of fatty acids and cholesterol in meat and fat, and blood lipid peroxidation were determined. Results: Thickness on the back fat (BF) at the level of 6-7 thoracic vertebrae with a live weight of 100 kg was 35.8 ± 1.65 mm in pigs of breed K, in hybrids - 27.6 ± 1.06, and in breed P - 19, 6 ± 1.43 mm. IMF in pigs of breed K was almost 4.5 times greater than that of breed P. IMF K breed contained 2 times less cholesterol than in P (2.34 vs. 4.68%). In the IMF, K was 2 times less polyunsaturated fatty acids (PUFA), than P, 7.82 and 15.22%, linoleic acid, 6.74% and 12.42% respectively (p <0.005).The organoleptic properties of meat and salted back fat were significantly higher in breed K (P = 0.05). Conclusion: The data obtained allow us to establish priorities in the use of products of specific breeds of pigs, depending on medical requirements.

The killer strains of Torulaspora delbrueckii can be used to improve the dominance of this yeast during must fermentation. The present work analyzes its usefulness for traditional sparkling wine making. T. delbrueckii killer strain dominated base wine fermentation better than non-killer strains and produced dried wines. The foam ability of T. delbrueckii base wines was very low compared to that of Saccharomyces cerevisiae. Significant positive correlations of foam parameters were found with some amounts of C4–C16 ethyl esters and proteins, and negative correlations with some antifoam alcohols. The organoleptic quality of T. delbrueckii base wines was considered unusual for cava making. While S. cerevisiae (single or mixed with T. delbrueckii) completed the second fermentation to produce dry sparkling wines with high CO2 pressure, single T. delbrueckii did not complete this fermentation, leaving sweet wines with low CO2 pressure. Death due to CO2 pressure was much higher in T. delbrueckii than in S. cerevisiae, making any killer effect of S. cerevisiae on T. delbrueckii irrelevant. However, the organoleptic quality of cava inoculated with mixtures of the two yeast species was better than that of wine inoculated exclusively with S. cerevisiae, and no deterioration in the quality of the foam was observed.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

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.

Sala lauak is a traditional food that is easily found in West Sumatra. The development of sala leak products is carried out by reducing oil using gelatinization techniques. The process that occurs in gelatinization is when the starch granules are given water and heat, the starch granules will expand. This study aims to (1) develop sala lauak products by gelatinization techniques on oil absorption, (2) determine the organoleptic quality of sala lauak products by gelatinization technique processes, and (3) determine the fat content of sala lauak products by gelatinization technique processes. This research method is Research and Development (RnD). The results of this study in the organoleptic quality produced by sala lauak with pragelatinization flour showed a significant influence on the quality of inner texture, outer texture, taste, shape, and color. The same thing also happened to a significant reduction in fat content by three times lower using pregelatinized rice flour which is 7.4% compared to ordinary rice flour which is 25%. Kata kunci  :   Sala Lauak, Gelatinization Technique, rice flour.
