The ice cream market is one of the developed segments of the food industry of Ukraine. Ice cream is a frozen product that is consumed all over the world. The work aimed to investigate the quality of parfait ice cream with vegetable fillings. The selection and justification of the components of the system, namely quail eggs, celery root, spinach leaves, was based on literature data and regulatory documentation, as well as laboratory data. Celery and spinach puree was chosen as one of the recipe components of ice cream, and the peculiarities of its preparation were studied. Parfait ice cream recipes with different ratios of vegetable fillers and pumpkin flour have been developed. The physiological and organoleptic parameters of ice cream with additional pumpkin flour, celery, and spinach puree were studied. According to the obtained results, the optimal content of pumpkin flour in ice cream is equal to 2–4 %, and vegetable puree – 25–35 %. It has been proved that pumpkin flour significantly affects the structural characteristics of ice cream mixes. They were melting resistance increases from 100 to 145 minutes. When increasing the flour content to 4 %. The dry matter content in ice cream varies depending on the amount of vegetable puree and pumpkin flour. However, the mass fraction of fat and dry nonfat milk residue does not change because the experimental samples were developed based on the composition of the control sample. Studies show that the new frozen dessert retains microbiological stability for six months. The combination of vegetable and dairy raw materials with pumpkin flour and quail eggs in the production of parfait ice cream provides the necessary whipping. It allows obtaining a product with specified rheological and physicochemical parameters.

The role of fats in nutrition is determined by their high-calorie content and participation in the construction of body tissues, together with proteins and carbohydrates. Enriched nutrition is of great importance in the complex of issues that determine its usefulness. Thus, the question of the effect of probiotics and sorbents in the diet on the animal organism has become very relevant. The purpose of the work was a comparative assessment of the composition and properties of adipose tissue of rams, consuming together and separately preparations with sorption and probiotic effect. The studies were carried out in two stages. In the first, during the scientific and economic experiment, 80 newborn rams grew and developed up to a year of age, followed by the slaughter of three animals from each group. In the second stage, samples of internal fat were examined according to some indicators. Sensory analysis revealed that all internal fat samples met the established requirements, while the color and consistency of the experimental samples improved. The dry matter content, including fat in the experimental samples of fat tissue, increased, and moisture decreased. The physical and technical parameters of internal fat also changed in the intergroup aspect. In the control sample, the iodine number decreased, and the saponification number, pour point, and melting point increased. Calculation of energy value indicates that in the first sample, the indicator increased by 0.08 MJ (0.23%); Group II – by 0.16 MJ (0.45%) and group III – by 0.25 MJ (0.70%). According to the sum of monounsaturated fatty acids, young group III was in the lead. The content of polyunsaturated fatty acids was the opposite. The biological effectiveness of fats is determined by the ratio that was better in the experimental samples. Thus, the inclusion of fodder additives in the diet of the rams of the Romanov breed helps to improve the quality of raw materials.

For the production of high quality silage, and reduction of losses of biological yield, the use of effective biological preparations is topical. In order to reveal the effectiveness of the preservation of nutrients from plant raw materials, a number of laboratory studies were carried out in 2016-2017 in the Tatar Scientific Research Institute of Agriculture (TatNIISKh). The object of research was haylage harvested from the green mass of alfalfa, grown on the experimental field “TatNIISh” in Laishevsky district of the Republic of Tatarstan. The nutritional value of the conserved green mass of the alfalfa (Medicago sativa) variety Aisleau in the phase of budding with different moisture was analyzed. Preservation of the planted plant mass was carried out using biological preparations Biotrof (St. Petersburg), Ferbak-Sil (Kazan), Bioamid-3 (Saratov). The variant with biological preparation Biotroph served as the control. The maximum content of exchange energy (EE), with an increased concentration of phytomass moisture, was established in the control sample, which was 2.36 MJ/kg and was higher than the experimental samples with Bioamid-3 and Ferbak-Sil preparations at 6.78 and 3.82 %. With an increased dry matter content in the green mass of alfalfa, this indicator was the maximum in the sample with the preparation Bioamid-3 (3.67 MJ/kg), which was higher than the control by 4.56%. The leader in the concentration of crude protein and crude fiber, with a high moisture content of raw materials, was set in a control sample and amounted to 6.11 and 6.07%, which were higher than the prototypes with Bioamid-3 and Ferbak-Sil preservatives by 0.33 and 0.16%, 0.76 and 0.48% respectively. The leading preservative for the preservation of raw protein and crude fiber, with reduced moisture content of raw materials, showed the drug Bioamid-3, whose indices were above the control by 0.39 and 0.23%.

Nowadays, the problem of healthy eating is acute. Most consumers prefer organic foods, dishes based on natural vegetables and fruits, and healthy nutrition. Thus, reducing calories content and increasing the nutritional value of sweet dishes is a promising area for the research. Therefore, the object of this study is the technology of whipped sweet «sambuk»-type dishes. To create the new desserts, non-traditional vegetable raw materials, namely physalis puree and banana puree, were chosen. Physico-chemical, mathematical, and dessert quality analysis methods were used in the study. One of the most problematic tasks in the technology of whipped desserts is the stabilization of the foam structure. Therefore, the inclusion of physalis puree and banana puree in the recipe affects not only the organoleptic properties, but also improves the physical and chemical parameters of the dish. In particular, the aggregate stability coefficient of the foam increases to 4.33 in the samples with banana puree and to 3.48 in the samples with physalis puree, which is 2 and 1.66 times higher than the same indicator for control sample. The specific volume also has a noticeable improvement (it is 1.5 times higher in samples with physalis puree and 1.16 times higher in samples with banana puree comparing to control). During the study the effect of selected raw materials on the dry matter content in new desserts was determined (it ranges from 36.5 % to 41.3 5 % in samples with physalis puree and from 23.2 % to 27.8 % in the case of adding banana puree) . The acidity of the model samples ranges from 4.8 to 4.61 pH in desserts with physalis puree, and from 5.53 to 5.41 pH in desserts with banana puree. Based on the expert assessment, the value of the sample quality criteria was determined. Conclusions are made on the expediency of non-traditional raw materials using in the preparation of whipped desserts.

Using natural multi-function phytochemicals could be one of the best solutions for clean-label production. In this study, dairy ice creams were prepared containing 14% egg yolk and 0.1% of thymol (THY), trans-cinnamaldehyde (TC), menthol (MEN), or vanillin (VAN). Then, the physical, chemical, and structural characteristics were evaluated. Magnetic resonance imaging (MRI) analysis (a rapid, chemical-free, and non-invasive tool) was carried out to evaluate the water distribution. A multivariate analysis was conducted among all studied variables. According to the results, the overrun of the MEN ice cream was significantly increased as compared to the control sample. The density was also reduced in the MEN sample. Meanwhile, the spreadability (%) of VAN was significantly increased after 6 min as compared to the control treatment. MRI analysis revealed that water distribution was significantly changed in the THY group. The firmness and viscosity of THY samples were significantly increased (p < 0.05). Multivariate analysis indicated that viscosity index and consistency were the top parameters affected by THY. The authors concluded that THY and VAN are promising stabilizers for ice-cream clean production.

China is the origin and distribution center of kiwifruit, as well as the country with the largest cultivated area and output of kiwifruit. A previous study found that a new kiwifruit virus, Actinidia yellowing ringspot virus (AYRSpV), has been detected in kiwifruit samples with yellowed leaves. The incidence of this virus was high in kiwifruit plantings in Shaanxi Province. To determine the symptoms of this viral infection and the effects of this virus on the yield and quality of kiwifruits, we measured leaf chlorophyll levels and the fruit yield, total sugar, total acid and dry matter contents of ‘Hayward’ kiwifruits grafted with AYRSpV-infected scions. The results showed that after AYRSpV infection, symptoms including chlorotic ringspots were mainly observed in the spring and gradually recovered with high summer temperatures. A few of the leaves that did not recover showed symptoms of albinism, which lasted until the leaves fell. We found that AYRSpV infection could reduce the chlorophyll content of ‘Hayward’ kiwifruit by 74.61-76.64%, the fruit yield by 14.50-24.10%, the sugar to acid ratio by 50.09-50.57%, and the fruit dry matter content by 1.67-1.78%. Our results showed that AYRSpV infection could significantly affect the yield and quality of ‘Hayward’ kiwifruit.

Winter Wheat Varieties

In order to realize the maximum potential parameters of winter wheat productivity, it is necessary, first of all, to use high-yielding varieties with optimal quality indicators of grain, as well as progressive agricultural technologies aimed at obtaining a stable crop yield. Winter wheat places high demands on its previous crops. Insufficient amount of productive moisture in the soil or its extremely low reserves affects the yield, and consequently, the quality of winter wheat grain according to unpaired predecessors. Moreover, dry autumn during the sowing period leads to its delay, which is the reason for obtaining uneven and weak seedlings. In this regard, studies have been carried out to study and assess the influence of predecessors on the agrocenosis, yield and grain quality of promising varieties of Adel, Grom, Tanya winter wheat. According to the experimental scheme, peas, corn for silage and sunflower have been identified as the preceding crops for winter wheat. Agrotechnology in experience is generally accepted for the foothill zone of the Republic of Adygea. The results of the research made it possible to identify the most optimal of the considered predecessors in the cultivation of winter wheat, capable of providing stable yields with high quality grain. Certain differences in the photosynthetic activity of the studied winter wheat varieties for different predecessors have been noted. It has been found that the leaf area of winter wheat varieties is in the range of 30,0–33,5 thousand m2/ha. The highest dry matter content in the range of 4,9–5,0 t/ha is observed in the Grom variety, and the predecessor is peas. The largest number of grains in an ear for three previous crops is 40–43 pcs / ear for peas. It also had a fairly significant effect on the weight of 1000 grains and the grain yield of winter wheat. For example, the weight of 1000 grains of the most productive Thunder variety varied from 40,1 to 41,6 gm, depending on the previous crop. According to the results of the experiments, the highest grain yield of winter wheat within the range of 5,3 t/ha has been noted for the Grom variety when cultivated for peas. The smallest grain yield in the range of 3,8–3,9 t/ha is typical for all studied varieties of winter wheat, namely, according to the cultivated predecessor – sunflower.

SUMMARY This study aimed to evaluate the agronomic, structural traits and chemical composition of andropogon grass subjected to different defoliation intensities and rest periods. Two defoliation intensities (15 and 30 cm) and four rest periods (25; 35, 45 and 55 days) were evaluated in a factorial completely randomized design, with four replications. The rest period promoted a linear decreasing effect (P <0.05) on the dry biomass of leaf blades in the two defoliation intensities. The dry biomass of stems showed an increasing linear effect (P <0.05) according to the rest periods in the two defoliation intensities. Production was recorded at 2427.71; 2907.39; 3325.72 and 3749.45 kg ha−1 for the periods of 25; 35; 45 and 55 days, respectively. The dry matter content showed an increasing linear effect (P <0.05) as a function of the rest periods evaluated in the two defoliation intensities. The rest period indicated a decreasing linear trend (P <0.05) for the crude protein content in the two defoliation intensities. A decrease of 0.9 and 0.7 g kg−1 was verified for each day of the rest period. For each additional day in the rest period, there was an increase of 1.2 and 1.5 g kg−1 DM in the neutral detergent fiber content at intensities of 15 and 30 cm. The andropogon grass pasture managed with a 25-day rest period and defoliation intensity of 30 cm showed high leaf/stem ratio and good nutritional value.
