In Uzbekistan, the main food product is bread, which is produced in various forms from local and imported wheat. Most of it is not studied by microelement analysis. The objective of this study is to quantify trace elements in locally produced wheat from various cultivated regions of Uzbekistan. Four different varieties of wheat are cultivated in Sirdarya, Tashkent region, Kashkadarya and Fergana were selected for analysis. Next, a comparative analysis of the elemental composition like iron, zinc, potassium, calcium etc., in the selected samples were studied. To carry out the above aims, an innovative research method was chosen, which is called improved instrumental neutron activation analysis. This method differs from others in its high accuracy in determining trace elements and its multi-element nature. Using this method, we can understand how insufficient nutrients are in baked goods made from wheat grain grown in Uzbekistan. Based on the results of the study, it can be recommended to enrich the soil with fertilizers high in iron and zinc. As a result, in turn, will have a positive effect on the health of the population, since today there is a shortage of the above listed elements. It was also revealed that the concentration of potassium and calcium in wheat cultivated in Uzbekistan is in a high state than other elements. Using the chosen method, two toxic elements were determined and according to the analysis for toxic elements, all four samples are recommended for consumption, as they do not exceed the permissible level for food safety.

The global character of sustainable development has made agritourism a popular phenomenon in both developed and developing countries, as it is advantageous from the standpoint of local economic and social development. Sustainability criteria play a vital role in controlling the quality of agritourist services of leader countries in agritourism. However, the development of agritourism in Uzbekistan has very different characteristics and development levels compared to other countries, especially countries in Western Europe. This article explores the integration of sustainability principles within the quality of agritourism services in Uzbekistan. As Uzbekistanʼs agritourism industry continues to grow, the importance of sustainability criteria in ensuring the quality of agritourist services becomes increasingly evident. A survey was conducted to investigate the importance of sustainability in the quality of agritourism services in Uzbekistan. The research findings indicate that there is a growing interest in agritourism in Uzbekistan. However, there is a need to improve the quality and sustainability of agritourism services in order to meet the expectations of tourists. This, in turn, enhances the overall visitor experience and contributes to the long-term sustainability of the industry. This article, relying on quantitative method, reveals the assessment of quality of agritourism services in Uzbekistan from the sustainability point of view. In the context of Uzbekistan, the article emphasizes the nationʼs strategic initiatives to promote sustainable resource management, water efficiency, conservation, and environmental preservation in its agricultural and agritourism sectors ensuring the delivery of high-quality services and products while contributing to environmental preservation.

Rosemary (Salvia rosmarinus) is an aromatic herb with a multitude of uses. It is both a seasoning in various dishes, and a natural remedy for several diseases mainly due to its anti-inflammatory and anti-oxidative effects. Plus, it is also used in cosmetic industry and for improving agriculture practices and helping the environment, since it may be a natural antimicrobial. It is worth noting that this plant is also grown and commercialized in Uzbekistan, thus, if added value is given to rosemary’s products, it has potential for improving living conditions and helping in the economy of local farmers and entrepreneurs. In this work, we discuss a technique for obtaining rosemary essential oil, rich in terpenes, by vacuum assisted hydrodistillation. This is a solventless environmentally friendly and safe technique that allows the obtention of an added value rosemary product where terpenes, compounds responsible for most of rosemary’s properties, are the most abundant. Two samples of locally acquired rosemary were sourced, essential oil was extracted, and characterization was then performed by Solid Phase Micro Extraction (SPME) and Gas Chromatography – Mass Spectrometry (GC-MS). As a comparison, a direct injection of a dilution of one of the essential oil samples was also performed. It was concluded that samples of essential oil obtained from both sources were entirely composed of terpenes or terpene derivatives. Besides, SPME was a superior method when compared to direct injection, since a larger number of volatiles was able to be identified.

Galactomannans, composed of galactose and mannose, may form gels and are considered safe because of their non-toxic, biodegradable, and biocompatible nature. As a result, they are widely utilized in the food industry as stabilizers and thickeners. Among galactomannan producing species, guar gum and locust bean gum are particularly important due to their economical relevance. Guar gum and locust bean gum are often adulterated with cellulose gums like xanthan gum and carboxymethyl cellulose (CMC). Adulteration of galactomannans with other gums may introduce uncertainties regarding functionality and complicate quality control, posing a potential problem for the food industry. Among the different techniques which have been used for determining and characterizing galactomannans, Fourier Transform Infrared Spectroscopy stands out. Especially when coupled to Attenuated Total Reflection (ATR), analyses are performed rapidly, with a minimum sample preparation, and without the need for solvent or previous extraction mechanisms. However, food is a very complex matrix that contains a high number of components which generate a multitude of spectral information and large data sets. Consequently, additional data processing tools such as chemometrics are needed to be able to draw useful information from spectra. Our goal in this work is to show how to optimize conditions for instrumental analysis by infrared spectroscopy of galactomannans and its constituent monomers and create a chemometric model where galactomannans could be differentiated as a single group. We successfully optimized the PCA model obtained after chemometric processing of infrared data through reducing dimensions by loadings selection.

Melon seeds have been recognized as a nutritional powerhouse, offering a range of essential vitamins and fatty acids that play a critical role in maintaining and enhancing our health. This study aims to analyse the fatty acid profile and water-soluble vitamins in melon seeds in order to highlight the importance of incorporating melon seeds into our diets, not only as a source of nutrients but also as a means of promoting overall health and well-being. It delves into the rich nutritional profile of melon seeds, underscoring their valuable contribution to a balanced diet. Water soluble vitamins C, PP and B1 were detected in melon seeds in this study. Regarding fatty acid profile, PUFA C18:2 was the most abundant (35.31%), followed by MUFA C18:1 (25.83%), although other unsaturated and saturated fatty acids were also determined. This comprehensive analysis of melon seeds’ nutritional benefits encourages further exploration of their potential in enhancing diet quality and supporting long-term health objectives.

In our republic in the process of preparing students for professional activity one of the urgent tasks is considered to be the development of their professional speech. It is very important for todayʼs specialist to be competent, competitive and able to communicate effectively in his future activity. However, the main problem is the teaching of professional culture and the holistic development of professional communicative competences. The aim of the article is to develop recommendations and methodological guidelines to ensure the cultural communication of future professionals. In particular, the experiment proves that the student should feel the benefit of learning a foreign language in the future and get used to independent work on the subject, and gradually the motivation to learn the language will appear. The study highlights the role of foreign language teaching in the interdependence of ‘language – communication – profession – cultureʼ, the interdependence of language and culture in the development of language skills, the systematic approach to the study of professional terms. It is a well-known fact that students, in addition to acquiring lexical and grammatical knowledge of a foreign language, should also have a perfect command of the culture and values of their country and of the country where the language is learnt. In order to effectively implement the business communication situation in the classroom, it is desirable for the student to ‘understand the foreignerʼ, to study and master the culture of the foreign country, the accepted rules and values. While doing research, the methodological recommendations and instructions for the systematic organization of foreign language teaching are given.

Central Asia faces substantial water scarcity due to increasing water demand driven by rapid urbanization, population growth, economic development, and inefficiency of irrigated agriculture. These developments are compounded by the effects of climate change, such as rising temperatures, loss of glacier mass and increased frequency of extreme events, including droughts. The region’s escalating water scarcity is causing disputes and straining rural livelihoods. Moreover, these challenges drive migration, creating considerable societal impacts. However, these issues remain underexplored in climate change research, making the region a global blind spot in climate adaptation and migration studies. We advocate for innovative research pathways that scrutinize smallholder adaptation strategies, examine the nexus between climate change, water scarcity, and mobility, and investigate tensions and cooperation over water resources. We conclude by emphasizing that substantial investments in inter- and transdisciplinary collaboration, improved data availability and quality, and strengthening of research and institutional capacities are essential to advance interdisciplinary climate impact research in Central Asia. Such efforts are vital for addressing existing knowledge gaps and enhancing evidence-based policymaking to improve the region’s position in current and future debates on climate change and sustainable development.
