Yavruyan, N.V. | Karapetyan, V.A.
Drinks saturated with biologically active substances can be obtained from non-alcoholic drinks or mixed berry juices. Natural plant materials were used as a source of physiologically valuable food components: citrus, stone fruits, berries, medicinal herbs, etc. We have developed new functional drink recipes based on directly pressed grape juice and natural raw materials rich in organic acids, vitamins, minerals, and other macro-elements and micro-elements such as feijoa, and blackberry. The Armenian Khndoghn grape variety was chosen to produce juices with the first pressing. This juice has a high biological value and harmonious taste with aromatic compounds. Three drinks were prepared, each containing grape juice and blackberry juice in 80:20, 90:10, and 70:30 ratios. Based on the results, optimal parameters and methods for extracting biologically active substances from plant raw materials (by extraction) were determined, and their organoleptic and dietary properties were improved. Due to the high content of vitamins, phenolic carbonic, organic acids, macro-elements, and micro-elements, new drinks have acquired excellent sensory and functional properties, so including them in serial production is recommended.

Badalyan, M.V. | Melikyan, A.Sh. | Aloyan, T.B. | Sahakyan, A.J.
The crops variety growing in Armenia has not been fully explored yet, hence, their genetic potential has not been revealed. Therefore, study of gliadin (Gld) locus contained in cereals’ embryo will further clarify the process of allelofunds and genotypes, homozygocity and heterozigocity, genetic similarity, genetic formula and genomic analysis of studied cultivars and wild species. The research was carried out in 20212022 in the educational laboratory of Food Quality Control of the Armenian National Agrarian University. The samples of the studied plants were taken from the exsitu seed collection of the National Gene bank of Agricultural Crops and their Wild Relatives of the “Scientific Center of AgroBiotechnology” branch of the Armenian National Agrarian University. From the electrophoretic spectrum of gliadin (Gld) for the study and identification of the genetic diversity of the inventory samples of cereals diversity protein formulas were deciphered, allelotypes and genotypes, homozygosity and heterozygos ity levels were determined, and genomic analysis was performed. According to the genomic analysis of the studied cereals varieties and wild relatives using protein markers, gliadin is spread into four zones: α, β, γ and ω. The genes regulating the synthesis of different parts of gliadin of α, β, γ, ω zones, are polymorphic located in chromosomes 6B(S), 1A(S), 1B(S), 1D(S), and in the case of Alti aghaj, Voskehask and Gjulgian also in 6A chromosome. There are no genes regulating the synthesis of gliadin segments in chromosome 6D(α). Research results, as genetic markers, can be used in identification and selection of studied varieties and wild species.

Hambardzumyan, A.M.
Throughout the current research 20 rare plant species of the RA mountain meadow zone has been studied and the botanical, topographical, cartographical and graphical descriptions have been compiled based on the existing spatial database. At the first research phase, three rare plants growing in the regions of Kotayk and Gegharkunik were mapped in the ArcGIS environment: Inula acaulis Schott & Kotschy ex Boiss., Acanthus dioscoridis and Draba araratica Rupr. For mapping, first their distribution per communities, settlements, operational significance and soil type was studied and identified, then digital mapping and analysis were performed in the GIS (Geographic Information Systems) environment. Based on the results, it was recommended to take appropriate measures for their preservation. Further changes in the ecological condition of rare plants growing in the selected regions were studied, maps of the given areas were drawn up in the GIS environment, and analysis of plant location, growth density, distance from the settlement, functional significance of the land, threats of extinction as a rare plant species, and conservation measures was performed. The received digital maps and analysis of mapping results justify the need for the development of additional measures (legal, economic, environmental). In order to map the mentioned plant species in ArcGIS environment, sequence of actions has been developed based on which it is possible to update, adjust and complete the database of rare plant species in the mountain meadow zone of Armenia and enrich the global biodiversity repository through the GBIF system.

The implemented research was aimed to evaluate the biological and economic indicators of the studied varieties of zucchini, to introduce the most valuable and highyielding variety into production. Expert studies were conducted in 20212022 in the Taghavard community of the Martuni region of the Republic of Artsakh, located at an altitude of 600m above sea level. Anna (control), Adana and Zartonk zucchini varieties were studied. Each cultivar was planted in a 50 m2 plot with four replications. In each plot, 123 plants were planted in two rows of 10 m length, with 90+70 cm interrow and 45 cm interplant distance. During the vegetation period, feeding with the norm of N 45 was done twice. Breeding varieties were evaluated according to growth and development stages, duration of vegetation, resistance to diseases and pests, and yield indicators. According to research, the Adana and Zartonk have a relatively long vegetation period (72 and 73 days), and the Adana (510 cent/ha) stands out in terms of crop structural elements and yield indicators. Adana and Zartonk are relatively resistant to diseases, and the difference in pest infestation is insignificant. Adana surpassed both Anna and Zartonk in terms of fruit percentage. It exceeded the highyield control by 135 cent/ha, at the same time, with high economic efficiency, it provided 135 cent/ha crop addition and AMD 420.000 additional profit per hectare. It is recommended to cultivate the Adana zucchini variety in the submountainous zone of the Artsakh Republic.

2023
Pipoyan, D.A. | Poghosyan, E.V. | Stepanyan, S.A. | Beglaryan, M.R.
Aflatoxin contamination in cereals poses a significant food safety and public health issue worldwide. Cereals, including rice, are a staple food in the diet of the Armenian population. This study aimed to assess the potential health risks associated with the exposure to aflatoxin B1 mycotoxin through rice consumption among the population of Yerevan. The daily intake of aflatoxin B1 through the rice consumption was estimated for the adult population across all administrative regions. The margin of exposure (MOE) method was used to evaluate the health risks associated with aflatoxin B1 exposure, with values less than 10000 considered a public health concern. The results indicated that the MOE for aflatoxin B1 exposure through rice consumption among the Yerevan population was less than 10000, which indicates the public health concern. Even the amounts of aflatoxin B1 within permissible levels were found to be potentially risky for the health of the population. Moreover, the MOE method used in this study can be a useful tool for assessing the risks associated with other food contaminants and guiding the development of appropriate risk management strategies. Hence, this study emphasizes the need for ongoing monitoring of aflatoxin levels in cereals, to ensure the safety of the food supply and protect public health.

Giloyan, G.H. | Ter-Isahakyan, L.G. | Kasumyan, N.A.
Throughout 121 days of winter pasture period, the animals aged 9.012.9 months old were grazed on without supplemental feeding. The study was carried out in the winter pasture of Yeghegnut community, Armavir region of RA. 10 heads from Holstein and Flekvi heifers each, kept in stalls were selected for the research. During 121 days of winter grazing, female calves from 9.0 to 12.9 monthold were in the pasture from 12:00 to 17:00 and during the remaining 19 hours in the cattle shed, without additional feeding. Absolute, average daily, relative weight gain and growth factors were determined on the basis of weighing and body part measurements at the beginning and end of winter grazing. According to the weight growth data, the absolute weight gain of a 9.012.9monthold female Holstein calf was 71.4 kg, the average daily weight gain was 610 g, the relative weight gain was 30.6 %, the growth factor was 1.4 times, compensation for 1 kg weight gainer – 5.4 energy feed units, and for the Flekvi breed – 62.6 kg, 535 g, 27 %,1.3 times, and 6.2 energy feed units, respectively. According to the data of linear growth, the height of the body parts of the 9.012.9monthold female Holstein breed in creased by 3.03.7, width by 3.03.3, length by 0.94.3, chest depth – 3.1, breast width – 3.6, forearm width – 0.7 cm, and Flekvi – 2.33.2, 0.72.6, 0.76.1, 1.7, 5.5 and 1.4 cm, respectively. Body composition indices also prove that the body structure of the 12.9monthold female Holstein and Flekvi breeds has also developed proportionally. Therefore, we suggest to graze 6monthold calves and older animals of different gender and age groups in the Armavir region of RA in winter pastures.
