An inadequate diet and lifestyle are major causes of various diseases. A healthy diet can prevent diseases and maintain a good health status. The present research objective was to test young consumers for their preference for healthy diets and their intention to purchase functional foods, as well as to identify factors that affect their attitudes. The study involved 720 consumers (average 20 years old), a structured questionnaire, and a specially-developed scientific methodology. The results were grouped based on sex and body mass index. The analysis focused on the points where consumers’ interest in healthy diet overlapped with health-related diet needs and how each of them corresponded with their knowledge on the following spheres: nutrition and health risks, labelled data use in food choice, preference for foods fortified with vitamins, minerals, dietary fibers, or functional foods with a poor sensory quality. The data were processed using descriptive statistics, Z-test, and correlation tests. All the consumers demonstrated healthy diet preferences and a significant positive relationship (p < 0.01) with the factors. They made an informed choice based on the labelled data and preferred foods fortified with vitamins, minerals, and dietary fibers, as well as functional products with a lower sensory quality. All respondents, regardless of sex and body mass index, demonstrated nutrition and health risk awareness. The health-related diet needs also affected their food preferences (p < 0.05), with some exceptions. The young consumers possessed sufficient basic knowledge on food quality, nutrition, and health. Their attitudes depended on their preference for healthy diets and functional foods. The novel methodology can be applied to other studies of consumer preferences.

Plants have been used as food additives worldwide to enhance the sensory qualities of foods and extend their shelf life by reducing or eliminating foodborne pathogens. They also serve as therapeutic agents due to their beneficial effects on human health through their anti-cancerous, anti-inflammatory, antioxidant, and immune-modulatory properties. Plants can be added to food as a dry powder, grated material, paste, juice, or as an extract that can be produced by a variety of methods. Plant extracts and essential oils are concentrated sources of bioactive phytochemicals that can be added to food in small amounts in a variety of forms. These forms include liquid, semi-solid, or dry powder for easy and uniform diffusion. Encapsulation can protect bioactive compounds from temperature, moisture, oxidation, and light, as well as allow for controlling the release of the encapsulated ingredients. Nanoemulsions can enhance the bioactivity of active components. This review explains how plant extracts and essential oils are used in the dairy industry as antimicrobial materials, analyzing their impact on starter bacteria; as natural antioxidants to prevent the development of off-flavors and increase shelf life; and as technological auxiliaries, like milk-clotting enzymes, stabilizers, and flavoring agents. Therefore, plant extracts and essential oils are a better choice for the dairy industry than plants or their parts due to a wide range of applications, homogeneous dispersion, and ability to control the concentration of the bioactive ingredients and enhance their efficiency.

Dihydroquercetin (3,5,7,3',4'-pentahydroxy-flavanone) is known for its powerful antioxidant, organ-protective, and antiinflammatory activities that can be applied to heavy-metal intoxication. The present research objective was to evaluate the possible protective potential of dietary dihydroquercetin in a rat model of subacute (92 days) intoxication with nickel nanoparticles. The experiment involved five groups of twelve male Wistar rats in each. Group 1 served as control. Other groups received nickel nanoparticles as part of their diet. Groups 2 and 4 received nickel nanoparticles with an average diameter of 53.7 nm (NiNP1), while groups 3 and 5 were fed with nanoparticles with an average diameter of 70.9 nm (NiNP2). The dose was calculated as 10 mg/kg b.w. Groups 4 and 5 also received 23 mg/kg b.w. of water-soluble stabilized dihydroquercetin with drinking water. After the dihydroquercetin treatment, the group that consumed 53.7 nm nickel nanoparticles demonstrated lower blood serum glucose, triglycerides, low-density lipoprotein cholesterol, and creatinine. Dihydroquercetin prevented the increase in total protein and albumin fraction associated with nickel nanoparticles intake. The experimental rats also demonstrated lower levels of pro-inflammatory cytokines IL-1β, IL-4, IL-6, and IL-17A, as well as a lower relative spleen weight after the treatment. In the group exposed to 53.7 nm nickel nanoparticles, the dihydroquercetin treatment increased the ratio of cytokines IL-10/IL-17A and decreased the level of circulating FABP2 protein, which is a biomarker of increased intestinal barrier permeability. In the group that received 70.9 nm nickel nanoparticles, the dihydroquercetin treatment inhibited the expression of the fibrogenic Timp3 gene in the liver. In the group that received 53.7 nm nickel nanoparticles, dihydroquercetin partially improved the violated morphology indexes in liver and kidney tissue. However, dihydroquercetin restored neither the content of reduced glutathione in the liver nor the indicators of selenium safety, which were suppressed under the effect of nickel nanoparticles. Moreover, the treatment failed to restore the low locomotor activity in the elevated plus maze test. Dihydroquercetin treatment showed some signs of detoxication and anti-inflammation in rats subjected to nickel nanoparticles. However, additional preclinical studies are necessary to substantiate its prophylactic potential in cases of exposure to nanoparticles of nickel and other heavy metals.

During the processing of sour cherries into different foodstuffs, a large amount of kernels is produced as waste material, which creates a significant disposal problem for the food industry. Sour cherry kernels containing 25.3–35.5% of protein can be used as a functional protein source in food production. Therefore, we aimed to study the effects of hydrolysis degree on the sour cherry kernel protein hydrolysates. Proteins were extracted from the defatted flour by isoelectric precipitation. The resulting protein concentrate was hydrolyzed (5, 10, and 15% hydrolysis) using Alcalase to yield hydrolysates. We determined their oil and water holding, emulsifying, gelation, and foaming properties, as well as apparent molecular weight distribution and proximate compositions. No protein fractions greater than an apparent molecular weight of about 22 kDa were present in the hydrolysates. The hydrolysis of the protein concentrate mostly led to an increase in protein solubility. As the degree of hydrolysis increased from 5 to 15%, the water holding capacity of the hydrolysates decreased from 2.50 ± 0.03 to 2.03 ± 0.02 g water/g, indicating its deterioration. The hydrolysates obtained at different degrees of hydrolysis had a better solubility than the intact protein concentrate. The oil holding capacity, the foaming stability, and the least gelation concentration of the protein concentrate could not be considerably improved by hydrolysis. In contrast, its emulsifying activity index and foaming capacity could be increased with a limited degree of hydrolysis (up to 10%).

Organic waste is a problem the cocoa industry has to handle. The industry produces a lot of cocoa bean husk, also called criollo cocoa husk. Cocoa bean husk is an underutilized cocoa waste that contains bioactive components in the form of phenols and flavonoids. Processed cocoa bean husk can be brewed as a functional beverage. The research objective was to test cocoa husk tea for sensory properties, bioactive components, and impact on blood cholesterol. This study used a randomized experimental design with six repetitions. Sensory data were processed using the Friedman and Wilcoxon signed-rank tests (α = 0.05) to determine the difference in sensory properties between each formulation of cocoa husk tea. The sensory evaluation involved 30 untrained panelists who gave the highest score to the formulation with 62.5% cocoa bean husk, 25% lemongrass, and 12.5% aromatic ginger, which could also reduce 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals (IC50 = 264.8675). The animal test showed that the cocoa husk formulation produced no significant difference (p > 0.05) in pre- and post-treatment, but was able to keep cholesterol within normal limits. Cocoa bean husk showed health benefits by its antioxidant properties and ability to control blood cholesterol.

Hyptis suaveolens L. is a medical and food plant that is commonly used to treat various microbial infections in humans in many countries of the world. We aimed to study the aqueous and ethanol extracts of H. suaveolens leaves to determine their antibacterial, in-vitro antioxidant, and phytochemical potentials for traditional medicine by using chemical analysis. The aqueous and ethanol extracts inhibited the tested bacteria species with zones of 0–15 and 10–29 mm, respectively. On the typed culture isolates, the inhibition zones were 8–25 and 16–32 mm for the aqueous and ethanol extracts, respectively. The minimum inhibitory concentrations of the aqueous and ethanol extracts were not different, while the minimum bactericidal concentrations for the aqueous extract was higher than that for the ethanol extract. The screened phytochemicals were qualitatively and quantitatively present in both extracts, except for saponins which were absent in the aqueous extract. The free radical scavenging activity in the aqueous and ethanol extracts was 1.44 ± 0.50 and 1.57 ± 1.40 mg of ascorbic acid/1 g dry leaves, respectively. The ferric reduction was 1.19 ± 0.40 and 1.69 ± 0.18 mg of ascorbic acid/1 g dry leaves in the aqueous and ethanol extracts, respectively. Hydroxyl scavenging was 65.0 ± 0.9 and 0.43 ± 0.50 mg of ascorbic acid/1 g dry leaves for the aqueous and ethanol extracts, respectively. The present research suggests that the extract of H. suaveleons can be applied as a controlling antibacterial growth agent against Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Streptococcus pneumoniae and other bacterial pathogens. It is noteworthy that the ethanol extract was more effective than the aqueous one in terms of the antibacterial, phytochemical and antioxidant activities.

Protein deficiency in the human diet is a widespread problem that affects all body systems. Nutrition adjustment appears to be one of the most effective ways to prevent this problem. This study was aimed at investigating the possibilities of using animal origin protein concentrates in bread baking industry. Study objects included five breads: one control and four samples containing protein concentrates. The test wheat bread samples contained 7, 9, and 11% of milk protein concentrate and 7% of whey protein concentrate to the mass of flour in the dough. Rheological parameters of the dough were obtained using an alveograph and a farinograph. The specific volume and sensory characteristics of the baked products as well as crumb deformation were evaluated. The nutritional value of two samples – control and with 9% of milk protein concentrate addition – was determined by calculation. Whey protein concentrate had a negative influence on the dough rheology. Low water binding capacity and specific volume as well as hard crumb make the usage of this product in bread baking unacceptable. The palatability test showed that bread supplemented with 9% of milk protein concentrate had the best sensory characteristics, compared to control and other test samples (with 7 and 11% of this concentrate). The predicted protein content was equal to 11.6 g/100 g that is 35% higher than in the control sample. Consequently, milk protein concentrate has a potential to improve biological value of the bread that can be further helpful to prevent the protein deficiency. Milk protein concentrate can be successfully used in the bread making process as an ingredient to correct the nutritional and biological value of baked products.

No agriculture is possible without soil. This article reviews available data on the soils of the Baksan Gorge located in the Kabardino-Balkarian Republic, Russia. The research objective was to collect and analyze information on the soil composition and crop yields in this region of the Central Caucasus. The review covered the last five years of scientific publications cited in Scopus, Web of Science, and Elibrary. It also featured contemporary and archival documents on the soil composition and periglacial agriculture in the Baksan Gorge. The agriculture and cattle breeding started in the Central Caucasus in the first millennium BC when the local peoples began to develop these lands as highland pastures and, subsequently, for agricultural farming. During the second millennium BC, crop production became one of the most important economic sectors in the Central Caucasus. Corn, barley, wheat, and millet were the main agricultural crops in the Baksan Gorge. Millet has always been a traditional Kabardian crop, and millet farming occupied the largest flatland areas. Barley was the staple crop in the highlands. Currently, the list of local staple crops includes corn, wheat, and sunflower. Barley, oats, peas, potatoes, vegetables, berries, nuts, grapes, and annual herbs are also popular. The past fifteen years have seen an extensive development of intensive horticulture in the Baksan Gorge. Agricultural ecology and production problems depend on the localization of agriculture in the Central Caucasus. This research reviewed data on the effect of soil composition on the yield and value of agricultural crops in the Baksan Gorge of the Central Caucasus.
没有土壤就不可能有农业。本文回顾了位于俄罗斯卡巴尔迪尼奥·巴尔卡里亚共和国的巴克桑峡谷土壤的现有数据。研究目的是收集和分析有关中高加索地区土壤成分和作物产量的信息。该综述涵盖了Scopus、Web of Science和Elibrary引用的过去五年的科学出版物。它还收录了关于巴克桑峡谷土壤成分和冰缘农业的当代和档案文件。农业和养牛始于公元前一千年的中高加索地区，当时当地人开始将这些土地开发为高地牧场，随后用于农业。在公元前第二个千年期间，作物生产成为中高加索地区最重要的经济部门之一。玉米、大麦、小麦和小米是巴桑峡谷的主要农业作物。小米一直是卡巴迪的传统作物，小米种植占据了最大的平原地区。大麦是高地的主要作物。目前，当地主要作物包括玉米、小麦和向日葵。大麦、燕麦、豌豆、土豆、蔬菜、浆果、坚果、葡萄和一年生草本植物也很受欢迎。在过去的十五年里，巴克桑峡谷的集约园艺得到了广泛的发展。农业生态和生产问题取决于中高加索地区农业的本地化。本研究回顾了中高加索巴克桑峡谷土壤成分对农作物产量和价值影响的数据。

Haploid technologies are used to create homozygous lines for accelerated breeding. We aimed to optimize the technology for using the isolated microspore culture in vitro to obtain doubled haploids of the carrot (Daucus carota L.). We studied two carrot varieties with different responsiveness to embryogenesis, Altajskaya lakomka and Breeding line 17. Carrot microspores were isolated from buds and cultivated in liquid nutrient media supplemented with an antibiotic and activated carbon in vitro. They were exposed to different thermal treatments. The experiment showed the benefits of combining cold pre-treatment of buds (5°C for 1 day) with heat shock of isolated microspores in vitro (32°C for 2 days). The induction of embryogenesis on the NLN-13 medium was twice as high as on the MSm-13 medium. The use of 1% activated carbon in 0.5% agarose increased the yield of embryoids by more than 1.5 times. 100 mg/dm3 of ampicillin was found to be the most efficient concentration. After 30 days of cultivation under optimized conditions, the yield was 161.3 and 44.0 embryoids per Petri dish for the cultivar Altajskaya lakomka and Breeding line 17, respectively. The induction of carrot embryogenesis is determined by the type and duration of thermal stress, the composition of the nutrient medium, the use of activated carbon as a sorbent, the addition of β-lactam antibiotics, and the type of explant exposed to thermal treatment. Our technology enabled us to obtain homozygous doubled haploid lines of carrots during a year, and these lines were included in the breeding process to create F1 hybrids.

Abiotic and biotic stresses have a major impact on crop growth. Stress affects the root system and decreases the amount of nutrients in fruits. Modern agricultural technologies help replace mineral fertilizers with new generation biopreparation. Unlike chemical fertilizers, biofertilizers reduce the risk of adverse environmental impacts. Of special interest are extremophilic microorganisms able to survive in extreme conditions. We aimed to study the phytostimulating ability of extremophilic bacteria isolated from disturbed lands in the coal-mining region. We isolated microorganisms from disturbed lands and studied their cultural, morphological, and biochemical properties. Then, we determined their ability to synthesize indole-3-acetic acids. The extremophilic bacteria were identified and subjected to biocompatibility testing by co-cultivation. Next, we created consortia of pure cultures and analyzed biomass growth. Finally, the biopreparation was experimentally tested on Trifolium prantense L. seeds. We isolated 10 strains of microorganisms that synthesized 4.39 to 16.32 mg/mL of indole-3-acetic acid. The largest amounts of the acid were produced by Pantoea spp., Enterococcus faecium, Leclercia spp., Rothia endophytica, and Klebsiella oxytoca. A consortium of Pantoea spp., E. faecium, and R. endophytica at a ratio of 1:1:1 produced the largest amount of indole-3-acetic acid (15.59 mg/mL) and accumulated maximum biomass. The addition of 0.2% L-tryptophan to the nutrient medium increased the amount of indole-3-acetic acid to 18.45 mg/mL. When the T. prantense L. seeds were soaked in the biopreparation (consortium’s culture fluid) at a concentration of 2.5, the sprouts were 1.4 times longer on the 10th day of growth, compared to the control. The consortium of Pantoea spp., E. faecium, and R. endophytica (1:1:1) stimulated the growth of T. prantense L. seeds. Our findings can be further used to develop biofertilizers for agriculture.
