Our research aimed to create a novel lactose-free sour milk product. This would be attractive for local producers and give new possibilities for the development of the dairy industry. The new product consists of two ingredients: yogurt and ricotta. Lactose-free yogurt technology has been developed for the first component production.Yogurt with 3 different curds has been produced and subjected to physicochemical and organoleptic testing. Bacterial culture consisting of Lactobacillus delbrueckii subsp. Bulgaricus and Streptococcus thermophilus were added in quantities of 100 units per 250 liters milk. The dose of lactase enzyme has been determined to decrease lactose content to 0.01 %:0.48 ml/l Ha-Lactase 5200 NLU. Technological parameters have been developed to ensure higher yield and faster protein separation for ricotta production. Three samples with different proportions (yogurt/ricotta) have been produced to obtain a product with a pleasant taste, aroma, and homogeneity for consumers. As a result of the organoleptic examination of the obtained samples, the optimal ratio has been defined as 90:10. Buckthorn puree was used as a natural additive. The food recipe has been developed, energy value and cost value have been calculated, and the titratable acidity of the food has been investigated.

It has been established that there is a need for regular inclusion of soil plowing in the process of minimum tillage. The need for regular inclusion of soil plowing in the process of minimum tillage has been established. A technological scheme for a combined machine has been developed, and a combined front plough for smooth plowing capable of performing both basic and surface soil tillage in a single pass has been proposed. Several geometric, operational, and technological parameters of the proposed plow working body have been determined. The feasibility of using a combined front plough for smooth plowing has been confirmed.

In 2021, the procedure for cadastral assessment approximated to market value of real estate for real estate taxation (adopted in 2019) came into force in the Republic of Armenia, whereby a new methodology for cadastral assessment of other land fund categories of the RA was determined. The procedure does not apply to agricultural lands, which to this day are assessed and taxed according to the methodology and values that were determined in 1997. In this article, we have addressed some points of the current methodology, which, in our opinion, require revision or additional argumentation.

The article presents the results of two-year investigations related to the effect of different soil cultivation methods, application times of equal doses of mineral and organic fertilizers and bio-humus with bentonite application against their background on the dynamics of macronutrients accumulation and their removal/output through the crop yield. Considering the changes in the winter wheat growth, development, and yield capacity under the effect of different soil tillage methods, as well as the applied fertilizers and bentonite in rainfed conditions, and also the nutrition characteristics, to get high and sustainable yield the cultivation of winter wheat should be implemented only through loosening method, while fertilization should be implemented by introducing natural rock bentonite into the soil either on the background of mineral fertilizers (N60P60K60) or bio humus (3.5 t/հa) in autumn, as a result of which the soil air, nutrition and humidity regimes improve, favorable conditions are created for the regular growth and development of the plant and 48.8-52 c/ha grain and 89-96 c/ha straw yield is ensured.

The main goal of the research was to study greenhouse tomato hybrids under hydroponic greenhouse conditions and to enhance the agro economic properties of tomato hybrids, offering farmers the hybrid that ensures high efficiency of tomato cultivation under hydroponic greenhouse conditions. During the vegetation period, phenological observations, biometric measurements, and crop counting were performed. Producing and selling vegetables in the local market is the primary activity of greenhouses and tomatoes occupy a significant place in vegetable production. In recent years, various varieties and hybrids have been imported into Armenia, most without testing. Tomato cultivation in greenhouses occupies a leading place in Armenia. The greenhouse tomato hybrids Merlis, Plumola, and Endeavor were researched.

The use of genetic methods seems to have briefly pushed back the use of culture methods. Currently, a new technique developed based on the latter – culturomics, enables the discovery and study of expanded bacterial diversity using a large number of culture conditions and media. This study aims to investigate the influence of heat shock on the qualitative and quantitative content of cultivable gut bacteria of Lehmann Brown chickens from the “Arax” chicken factory.The chickens (5 months old, weighing 1.4-1.7 kg) of the “Arax” poultry factory in Armenia were transferred to a sterilized test room with the necessary conditions. After four days of maintenance in a new environment (temperature 25 0C), fecal samples were taken from the hens. After that, the hens were kept at 35 0C for a day, followed by another sampling conducted a day later. The current investigations have emphasized that the bacterial number and diversity of hen gut microbiota undergo changes under the influence of heat stress.

Research works demonstrate a rising demand for high-quality wine in Armenia. Our objective was to produce premium red and rosé wines using the relatively unexplored grape variety “Hastakot”. Throughout the research, we utilized various winemaking technologies to produce red and rosé wines of the grape variety “Hastakot”. Simultaneously, multiple physicochemical and sensory attributes were investigated in the produced must and wine. The obtained results highlight the ability to make unique wines from the grape variety “Hastakot”, indicating a potential market impact and gaining consumer appreciation.

The cadastral assessment and net income of agricultural lands in the Republic of Armenia are determined by the government decision of July 3, 1997 No. 237 “On approval of the state land cadastre data of agricultural lands and unsuitable lands of the Republic of Armenia”. Agricultural lands are changed by decision of the Government of the Republic of Armenia dated September 17, 2009 No. 1066-N “On approval of the procedure for changing agricultural lands of the Republic of Armenia”. In this article, we examined some aspects of the current methodology, which, in our opinion, require revision or additional arguments. We calculated the missing values in the Appendix to Decision N 237 of 1997 of the Government of Armenia. These values are the net income of some groups of cadastral assessments of agricultural lands using the formula in the article. The map of land-cadastral zoning of the Republic of Armenia, which has not yet been digitized, was digitized for the first time and schematically presented in the article.

The research aimed to investigate the effect of processing on the antioxidant activity and phenolic content of Armenian flaxseeds. This is crucial for understanding their potential health benefits. For laboratory investigations, six flaxseed samples were germinated with different durations (24 h, 48 h, and 72 h) and three of these samples were also heat treated (100 0 C with a duration of 30-40 min). As part of the experiment, ungerminated samples and unheated samples were also tested to compare outcomes. All samples of flaxseeds were analyzed for antioxidant activity using the FRAP (Ferric-Reduced Antioxidant Power) method. The total phenolic content (TPC) was determined using the “Folin Ciocalteu” reagent, with gallic acid as a standard. The obtained results highlight the significant role of processing techniques in determining flaxseed antioxidative activity. Specifically, longer germination periods, notably 72 hours without heat treatment, exhibited antioxidant activity and phenolic content. This contrasted with decreased levels in heat-treated samples. By incorporating flaxseeds, particularly those germinated for extended durations and without heat treatment, into diets, individuals may enhance antioxidant intake. These findings support the development of innovative functional food products aimed at mitigating chronic diseases. Overall, the study contributes valuable insights into the nutritional significance of flaxseeds and emphasizes their potential as functional food components. This fosters advancements in health-promoting dietary practices and product development.

A salting and ripening process is one of the main and most important steps in producing meat products, especially ground-dried and smoked ones, which undergo complex biochemical and microbiological processes and generate low molecular compounds. This ensures the quality and energy value of a finished product. The development of new methods is therefore necessary to accelerate the ripening process and improve the product›s useful properties. This study aims to develop an optimal dosage of rose hip extract that will accelerate and regulate the ripening process and saturate the high levels of vitamin C in the final product. Maturation was carried out under the same thermal conditions, the duration of maturation was determined by pH. The change in vitamin C content in salted semi-finished meat products was also determined. The research results were compared with the technical regulation of Customs Union Technical Regulations 034/2013 “Safety of meat and meat products”. By introducing this technology in the production of meat products, we will increase the shelf life of the finished product, reducing costs by reducing production costs.
