Перспективы развития рынка мяса и мясной продукции России в условиях новых вызовов

Abstract. Topicality of adjusting the targets of agri-food policy and food security policy in Russia is determined by changes in both external and internal conditions for agri-food complex functioning. Macroeconomic forecasts create the basis for revising and adapting the directions of development of the main sectors of the agri-food complex. The purpose of this study is to develop alternative forecasts for the production and consumption of main types of meat and meat products in Russia to substantiate strategies for domestic market development. Methods. General scientific methods of cognition were used, such as dialectics, analysis and synthesis, and monographic methods. Forecast calculations were carried out using economic and mathematical methods. The scientific novelty of the study is as follows: the development of a methodological approach to substantiate the prospects for the development of meat and meat products production considering the balance of the meat products market and the consistency of conflicting targets in the field of import substitution, physical and economic accessibility of food for the country's population. The methodological recommendations developed during the study can serve as the scientific basis for midterm development programs of individual segments of the Russian food market. Results. It was revealed that in the short term, new challenges related to economic sanctions and COVID-19 had minor impact on the meat and meat products market. Limiting barriers to development are systemic economic problems: demographic situation and low real income. Alternative forecasts for development of markets for the main types of meat were developed.

Study Of Some Chemical, Physical and Microbiological Properties Of Five Types Of Local Iraqi Date Products and Their Impact On Green Marketing

Exploring a Cheese Ripening Process That Hinders Ochratoxin A Production by Penicillium nordicum and Penicillium verrucosum.

A lack of control of the technological abiotic parameters apparent during cheese manufacture, including temperature and relative humidity, results in this dairy product being prone to mold contamination. Sometimes, inoculant molds are used to obtain the characteristic sensory properties of this type of product. However, during the maturation process, some unwanted molds can colonize the ripening cheese and produce mycotoxins. Mycotoxigenic molds such as Penicillium nordicum and Penicillium verrucosum can colonize ripened cheeses, contaminating them with ochratoxin A (OTA), a nephrotoxic 2B toxin. Thus, the presence of OTA in cheeses could represent a hazard to consumers' health. This study has evaluated the growth and OTA production of P. nordicum and P. verrucosum on a cheese analogue under simulated ripening conditions of 10 and 15 °C and 0.96 water activity (aw). Ecophysiological, molecular, and analytical tools assessed the mold growth, gene expression, and OTA production under these environmental conditions. Both species were able to effectively colonize the cheese under these ripening conditions. However, neither species expressed the otapks and otanps biosynthetic genes or produced phenotypic OTA. Therefore, these results suggest a relatively low risk of exposure to OTA for consumers of this type of cheese product. The conditions used were thus appropriate for cheese ripening to minimize the potential for contamination with such mycotoxins. An appropriate adjustment of the technological ripening parameters during such cheese manufacture could contribute to OTA-free cheeses.

Quality characteristics and bread-making properties of Korean whole wheat flour produced at different addition levels of wheat bran

Whole wheat flour is produced by grinding wheat grains and blending each milling fraction such as wheat bran and white flour with no specific standard for the proportions. An exploration on classifying and utilizing Korean whole wheat flour is required to increase the practical use of many different types of Korean wheat flour products. This study aimed to examine factors for categorization and processability of Korean whole wheat flour by investigating quality characteristics and bread-making properties of Korean hard wheat flour samples produced with different levels of wheat bran (0% as control, 5%, 10%, 15%, 20%, and whole grain wheat flour). The ash content of flour samples was divided into six gradational categories, which could be suggested as classification criteria for Korean whole wheat flour. The main parameters of dough and gelatinization properties of the flour samples exhibited downtrends, but nutritional constituents demonstrated uptrends with increasing bran addition level. The bread specific volume, hardness, chewiness, and brittleness of bread had strong correlations with dough stability and pasting parameters, which could be presented as significant factors for predicting bread-making properties of Korean whole wheat flour.

Volatiles and bacterial composition of pickled bamboo shoots within 10 pre-packaged Chinese Luosifen disclosed by GC–MS, GC-IMS, and high-throughput sequencing

Pickled bamboo shoots represent a type of fermented bamboo shoot product. In China, pickled bamboo shoots are regarded as the soul of Luosifen, which is a local specialty food in Liuzhou (Guangxi Zhuang Autonomous Region, China). To exemplify the uniqueness of the pickled bamboo shoots, we analyzed the pickled bamboo shoots within 10 pre-packaged Chinese Luosifen to determine the composition of volatiles and bacteria, and subsequently examined the correlation between them. The volatiles were identified using gas chromatography–mass spectrometry (GC–MS) and gas chromatography-ion mobility spectrometry (GC-IMS). Meanwhile, high-throughput sequencing technology was employed to investigate the bacterial composition. The results indicated that the pH values of the samples exhibited minimal variance (ranging from 3.71 to 4.53), while the total acid (measured as g lactic acid /L) varied (from 4.65 to 10.3 g lactic acid /L). Lactic acid, acetic acid, and succinic acid were the predominant organic acids. 50 volatiles were detected by HS-GC-MIS, and 108 volatiles were identified by HS-SPME-GC–MS. p-Cresol (76,541.67 < OAV < 248,166.67), acetic acid (482.31 < OAV < 1164.62), and hexanoic acid (108.33 < OAV < 1333.33) were the common distinctive volatiles among the 10 samples. Proteobacteria and Firmicutes, as the dominant phyla, were positively and negatively related to 1-butanol (R = 0.66, − 0.66), respectively. Industrial relevanceIn China, Luosifen, as a local delicacy, enjoys popularity among the public for its sour, smelly, spicy, fresh, and oily features. Among them, pickled bamboo shoots are highly sought after for their distinctive sour and refreshing flavor. Nevertheless, some individuals cannot tolerate the sour smell of pickled bamboo shoots yet still have a desire to consume Luosifen. To address this issue, it is crucial to determine what constitutes the pungent odor in pickled bamboo shoots and subsequently regulate it to meet the requirements of diverse consumers and enhance the economic benefits of the Luosifen industry. This study disclosed the stimulant flavor substances of pickled bamboo shoots in 10 pre-packaged Luosifen detected by GC–MS and GC-IMS, offering a theoretical foundation for subsequent regulation.

Extended applications of the small-scale radio frequency system for improving the heating performance of multi-component rice

With the changing lifestyles and the rapid development of the prepared food industry, there are many different multi-component rice-based foods on the market today. Further, manufacturers of multi-component foods prepare different types of rice products and provide them to markets and restaurants. In this study, the multi-component rice was heated by a self-built small 50 Ω, 13.56 MHz radio frequency (RF) heating system to explore the effective scheme for improving heating uniformity. The dielectric properties (DPs) of the single-component material (cooked rice, carrot, and sausage) were first measured and the heating rates were recorded at a selected input power level of 500 W and electrode gap of 80 mm. Based on the above results and the occurrence of edge effect, three types (I, II, and III) of the multi-component test samples were designed to compare the heating performances and the quality changes after RF treatment with three different electrode gaps (70, 80, and 90 mm). Results demonstrated that the Type-I sample arrangement resulted in a relatively shorter treatment time and a lower heating uniformity index as compared to the other two sample arrangements (Types of II and III). It also resulted in a more uniform temperature distribution and better-quality retention than that was possible with the single-component treatment. Thus, the layered scheme (Type-I) based on the DPs of the material could effectively improve the RF heating uniformity of multi-component food.

Electro-activated persulfate degradation of chlorophene (CP): Kinetics, mechanisms and theoretical calculations

BackgroundActivation of persulfate (PS) to generate sulphate radicals is an effective method to remove organic pollutants from water. However, conventional methods still face challenges in efficient wastewater treatment due to the need to add additional reagents. MethodsDegradation of chlorophene (4-chloro-2-(phenylmethyl)phenol, CP) by activation of PS through electro-activation. Comprehensive experimental and product toxicity results showed that Electro-PS is an environmentally friendly and effective method for removing pollutants from water. Significant findingsWhen the pH value was 7.0, the current density and PS concentration were 10 mA/cm2 and 1.0 mM, respectively, the removal rate of CP reaches 90.1 % within 10 min. The presence of humic acid (HA), NO3−, and HCO3− may deplete the active substance and thus inhibit the degradation of CP. On the contrary, Cl− could promote CP degradation due to the generation of Cl•. The EPR results indicated that SO4•−, •OH, 1O2, and O2•− contributed to the degradation of CP, and the quenching experiments proved their contributions to be 40.6 %, 24.9 %, 11.3 % and 7.5 %, respectively. The main types of oxidation products of CP in the Electro-PS system were identified and oxidation pathways were determined by mass spectrometry, and the product structures were verified by theoretical calculations. Evaluation by the ECOSAR software showed that the toxicity of CP oxidation products was reduced.

Exploring the Determinants of Tobacco Usage Among Adolescents: A Cross-Sectional Study in Western Maharashtra.

Introduction The widespread use of tobacco is a major global health threat, causing significant morbidity and mortality. The World Health Organization (WHO) estimates that annually, millions of people die prematurely due to tobacco use, with this number projected to increase significantly in the future. Developing countries, including India, bear a substantial burden of tobacco-related deaths, often beginning during adolescence. This study estimated the prevalence of tobacco use among adolescents in the 13-19 years age group, identified the types of tobacco products used, explored the reasons for initiation, and examined the influence of family, peers, and socio-demographic factors on tobacco use. Methods A community-based cross-sectional study was conducted from August 2022 to June 2024 in a medical college's urban and rural field practice areas in Pune district, Maharashtra. A total of 310 adolescents were surveyed using convenience sampling. Data were collected using a pre-designed, pre-tested questionnaire, and statistical analysis was performed using Jamovi software version 2.3.28. Chi-square and Fisher's exact tests were applied to assess associations between variables. Results Out of 310 participants, 94 (30.32%, 95% CI: 25.25%-35.77%) reported using tobacco. Among these 94 participants, 82 (87.23%) used smokeless tobacco, 19 (20.21%) used the smoked form of tobacco, and seven (7.45%) used both forms. The mean age of initiation was 15.94 years for smoking and 15.59 years for smokeless tobacco. The data indicate a higher percentage of tobacco use among females (50%) compared to males (24.8%). However, in terms of absolute numbers, more males (60) than females (34) reported using tobacco due to the larger number of males in the study sample. The most common reasons for initiation included curiosity (43.74%) and peer pressure (53.99%). Specifically, 49 individuals (42.6%) aged 13-15 were using tobacco, compared to 23 individuals (30.3%) aged 16-17, and only 22 individuals (18.5%) aged 18-19. Participants from urban areas reported higher tobacco use (48%) compared to those from rural areas (46.7%). Among those from joint families, about 24 (31.6%) reported tobacco use, while in nuclear families, it was slightly lower at about 70 (29.9%). Conclusion Factors such as peer pressure and curiosity played significant roles in the initiation of tobacco use, with more than half of the participants citing peer influence as the primary reason for starting. This study revealed differences in tobacco usage patterns across age groups, with younger participants showing higher usage rates. The findings highlight the need for targeted interventions, such as health education and anti-tobacco media campaigns, to reduce tobacco use among adolescents.

Microenergy shockwave therapies for female stress urinary incontinence.

Stress urinary incontinence (SUI) is one of the pelvic floor disorders affecting tens of million of women worldwide. In general, non-surgical options have relatively limited efficacy. The most effective treatment is mid-urethral sling surgery which carries substantial risks of perioperative and postoperative complications. Regenerative therapy with the injection of several types of stem cells and stem cell products is promising but further investigation is needed before clinical implementation can be considered. In recent years, the application of microenergy therapy as a non-invasive treatment for SUI has received increasing attention. Preclinical animal studies of these models have demonstrated that low-intensity extracorporeal shockwave therapy (Li-ESWT) and microenergy acoustic pulse (MAP) therapy are capable of regenerating urethral sphincter tissue and pelvic floor muscles leading to improved urinary continence. One pilot clinical trial with Li-ESWT also reported improved quality of life in women with SUI as well as the symptoms. The objective of this review is to summarize the potential mechanisms associated with Li-ESWT and MAP therapies of SUI: (I) activation of tissue-resident stem cells; (II) regeneration of musculature in the urethra and pelvic floor; (III) improvement in biomechanical property of pelvic floor muscles; (IV) modulation of cellular signaling pathways. Further studies of the molecular mechanisms, optimal treatment dosage and schedule, and potential long-term side effects are needed to provide this non-invasive regenerative therapy for millions of women with SUI.

A controlled vocabulary and taxonomy for the submission of quality attributes for therapeutic proteins

Structured product quality data offer tremendous promise to revolutionize the submission of drug applications. However, the quality attributes for biological products do not have a systematic naming taxonomy, and consequently this limit poses a critical challenge in the development of systems for structured regulatory submissions. Here, we describe the creation of a controlled vocabulary with a structured taxonomical naming approach for quality attributes of therapeutic proteins. Additionally, we endeavor to make the case for why such systematic harmonized naming is required to support the successful implementation of structured data systems. We also describe the key principles of our structured naming approach, including a top-down view of the product and protein structure and a distinction between a quality attribute and the test to evaluate the attribute. Finally, we describe how this approach can accommodate emerging product types, advanced manufacturing technologies, and be used across the variety of submission sections in a regulatory dossier that discusses quality attributes.

BLACKPINK Endorsement Effect: Luxury Perfume Brand Image and Consumption Behavior of Chinese College Students

This study explores the impact of K-pop stars on the brand image of luxury perfumes, with a particular focus on how Chinese university students perceive and behave towards perfumes endorsed by BLACKPINK members. This study employs a combination of textual analysis and questionnaire surveys to analyze the advertisements of four luxury perfume brands - Celine, Dior, YSL, and Tamburins- endorsed by BLACKPINK members. Through a survey of 117 Chinese university students, the relationship between the brand image conveyed by the advertisements and the consumers' brand perception is examined. The results indicate a high consistency between the visual and textual elements of the advertisements (such as the presentation style and emotional tone of the endorsers) and the perceived brand image by consumers. Moreover, the study reveals the synergistic effect of visual and textual elements in advertisements, which not only enhances the efficiency of brand information transmission but also improves consumers' overall perception and emotional connection with the brand. This study not only demonstrates the powerful influence of K-pop star endorsements but also provides important strategic insights for luxury brands in choosing endorsers and designing advertising strategies. By leveraging celebrity influence effectively, brands can achieve marketing goals and deepen the connection between consumers and the brand. Future research could further explore the relationship between different endorsers and different types of products, and how this relationship influences brand loyalty and purchasing behavior among various consumer groups.

Organoleptic Assessment of Fish-Based Ready-to-Use Supplementary-Food (RUSF) Rich in Essential Fatty Acid for Pregnant Women to Prevent Stunting

Stunting is a critical health issue with short- and long-term impacts on health and economic outcomes. Insufficient nutritional intake during pregnancy and early childhood is a key factor contributing to stunting. This study examines the efficacy of fish-based Ready-to-Use Supplementary Food (RUSF) rich in omega-3 fatty acids in preventing stunting by improving maternal nutrition during pregnancy. One of the determining factors is insufficient food intake in quantity and quality during pregnancy and the early stages of introducing complementary foods alongside breastfeeding. Long-chain omega-3 fatty acids (LCPUFAs) have been shown to positively influence health and linear growth for fetuses and children under two years of age. The use of fish-based functional food for pregnant women and children under two years to prevent stunting has not been widely carried out in Indonesia, in terms of the formulation, product types, or efficacy of Ready-to-Use Supplementary Food (RUSF). The stages of the research method were (1) identifying the content of omega-3 fatty acids and heavy metals in lemuru fish, (2) developing RUSF formulations based on snack bars and lemuru fish sausages made from omega-3-standardized raw materials, and (3) conducting acceptance tests of these RUSF products on children aged 6-35 months and pregnant women. This research is expected to develop nutritional supplements in the form of RUSF based on lemuru fish, mackerel, and tuna to serve as functional food products that help pregnant women prevent and control stunting.

Issues of Improving Expense Tracking and Calculating Prime Cost in Agriculture

Objectives : This article is devoted to the consideration of the issues of cost accounting and cost calculation in agriculture. In addition, the article highlights the issues of the correct distribution of costs by cost items and objects, as well as the correct calculation of the cost of Uzbekistan's products. In addition, Uzbekistan is an agrarian country, so the article presents suggestions and recommendations for improving the accounting of costs and production costs in agriculture. Previous studies in this area conducted in other parts of the world indicate a direct relationship between the indicators of production costs and market indicators; however, based on the features of Uzbekistan, it may be different, given the accounting policy and the specifics of agricultural costs. Methods: A linear regression method to determine the impact of costs and methods of calculating the cost of production was used. Costs are divided into variables and constants. Based on the features of agriculture, simple, advanced, and regulatory methods are used. Each of these methods is associated with variables and regresses individually for each type of agricultural product. Findings: Our results confirm that there are some methods of calculating the cost of production of farms. The results also indicate that the correct determination of the cost of production affects the profitability of these farms. The results obtained indicate that the calculation of the cost of agriculture is an indicator of the profitability of farms in Uzbekistan in the short term. The impact of the change in the cost of agricultural products influences profitability, in the end on profit; as it influences the prices of sales of products in the end affect the financial performance of farms. Novelty: The impact of the cost of agricultural products on the profitability of farms is becoming more important than ever before since the negative externalities of cost changes affect the financial performance of farms.

Hybrid six sigma based on recursive kalman filter and weibull distribution to estimate the lifespan of Bulb LEDs

The durability of LED bulbs ensures that the lights can operate for a long time without needing to be replaced or maintained too often. The brightness of high-power LED bulbs provides a strong and efficient light source, saves energy, and has a long lifespan. The traditional method of testing LED bulb life span has limitations such as long testing time, limited accuracy, high cost, inability to predict accurately, and failure to respond quickly. Therefore, the development of new and improved testing methods is necessary to effectively and accurately evaluate and ensure the durability of LED bulbs. This research paper proposes a hybrid Six Sigma method based on the recursive Kalman filter and Weibull distribution to estimate the lifespan of Bulb LEDs. The goal of the new method for evaluating LED bulb life is to provide accurate, reliable, and multi-dimensional information about the life of LED lamps, meeting the requirements of accuracy, diversity, time-saving, resources, credibility, and the ability to evaluate from a variety of perspectives. As a result of the research, the recursive Kalman filter method has strengths such as high accuracy, flexibility, saving computational resources, the ability to handle inaccurate data, and scalability. When applied to LED bulb life assessment, it provides an accurate and reliable estimate of LED lamp life. Research results on longevity testing were reduced from 1650 h to 710 h. The end-of-life test time is 710 h, and the aging time per life test cycle is 135 h. The cost of life testing is reduced from 2100.17 USD to 410.12 USD. This LED bulb lifespan testing method can be applied to similar types of LED products to improve the company's productivity and business efficiency.

Dong Brocade in Hunan, China: Literacy and Re-invention of Tradition in the Perspective of Intangible Cultural Heritage Protection

In this study, we investigated (i) the history, development, and current situation of Dong brocade in the Dong Autonomous County of Passage, Hunan Province, China, from the perspective of the historical development of the Dong ethnic group and (ii) the traditional re-invention of Dong brocade weaving techniques and the re-creation of the traditional educational literacy in the perspective of the intangible cultural heritage protection. This study is qualitative, mainly using the concepts of traditional re-invention and educational literacy, adopting two methods of data collection, namely, documentary research and field survey, and presenting them in the form of descriptive analysis. The results of the study show that the Dong people in China have a long history, and Dong brocade is a product of the social life and ecological environment of the local Dong people. With the development of the times and under different social demands, Dong brocade has been recreated in terms of the production process, raw materials, product types, and traditional education, and the literacy of Dong brocade has also been “recreated.” This study explores how to promote the traditional re-creation of Dong brocade from the perspective of intangible cultural heritage protection and how to realize the educational literacy of Dong brocade in various ways with the support of the government, enterprises, and universities. This is of great value to the theoretical study of the living heritage of Dong Brocade and the Chinese government’s promotion of the protection and development of minority cultures.
