Carotenoids, a group of phytochemicals, are naturally found in the Plant kingdom, particularly in fruits, vegetables, and algae. There are more than 600 types of carotenoids, some of which are thought to prevent disease, mainly through their antioxidant properties. Carotenoids exhibit several biological and pharmaceutical benefits, such as anti-inflammatory, anti-cancer, and immunity booster properties, particularly as some carotenoids can be converted into vitamin A in the body. However, humans cannot synthesize carotenoids and need to obtain them from their diets or via supplementation. The emerging zoonotic virus severe acute respiratory syndrome coronavirus 2, which causes coronavirus disease 2019 (COVID-19), originated in bats, and was transmitted to humans. COVID-19 continues to cause devastating international health problems worldwide. Therefore, natural preventive therapeutic strategies from bioactive compounds, such as carotenoids, should be appraised for strengthening physiological functions against emerging viruses. This review summarizes the most important carotenoids for human health and enhancing immunity, and their potential role in COVID-19 and its related symptoms. In conclusion, promising roles of carotenoids as treatments against emerging disease and related symptoms are highlighted, most of which have been heavily premeditated in studies conducted on several viral infections, including COVID-19. Further in vitro and in vivo research is required before carotenoids can be considered as potent drugs against such emerging diseases.
This paper examines the problem of food security in the Republic of Kazakhstan over the past 10 years. Based on statistical data, an assessment was made of the prevalence of malnutrition among the population of the country, including children under 5 years of age. There has been a trend towards for an improvement in the nutrition of the population for a few indicators; however, further optimization of food security indicators is required to achieve the goals of sustainable development (SDGs) of the FAO WHO Agenda for the period up to 2050 in Kazakhstan and in its individual regions. The paper reflects data on demographic changes over the past 10 years and its self-sufficiency in basic foods for 2019. A high degree of self-sufficiency in meat products (117.6%) is revealed in the population of the Republic of Kazakhstan. However, self-sufficiency in dairy products is at an extremely low level (0.1%). Camel breeding has been successfully developing in the country over the past 10 years. However, the number of camels in the country is still at a low level. Camel milk can be considered as a great source of macronutrients, its daily consumption partially facilitates the problem of Food Security in Kazakhstan.
The present paper features a comparative analysis of the biological value of milk obtained from cows, goats, mares, and camels. The biological value of the milk was estimated by protein and lipid components using computational methods of food combinatorics. According to the chemical composition of the milk, camel’s milk proved to have the highest protein content (4.0%). Cow’s and goat’s milk were much poorer in protein: its content was by 0.8 and 1% lower, respectively. The lowest weight fraction of protein was in mare’s milk, which was by 1.8% lower than in camel’s milk, and also by 0.8 and 1% lower if compared to goat’s and cow’s milk. In addition, mare’s milk differed from other types of dairy raw products by its lowest fat content (1.0%), which was 4.1, 3.2, and 2.6% lower than the fat content of the milk obtained from camels, goats, and cows, respectively. The high fat content of camel’s milk was associated with its highest energy content (82 kcal), while the energy content in goat’s milk was 14 kcal, cow’s milk – 17 kcal and mare’s milk – 41 kcal. Camel’s and goat’s milk had a high content of solids (15% and 13.4%, respectively), whereas mare’s milk had only 10.7% and cow’s milk – 11%. The paper also introduces some data on the protein component of the milk obtained by using the amino acid scoring method. Mare’s milk proved to have the highest value of the amino acid composition index (0.6), which over-indexed the values for cow’s, goat’s, and camel’s milk by 0.13, 0.14 and 0.18, respectively. The biological value of the lipid component of the product is characterized by its qualitative composition of fatty acids. The highest values of the index of fatty acid composition belonged to mare’s milk: 0.58 and 0.42, taking into account the 3 and 5 calculation components. Camel’s milk was found inferior to mare’s milk by 0.9. The lowest values of the lipid composition index were observed for cow’s and goat’s milk. The research involved a complex calculation of the level of balance in the composition of milk. All the livestock animals were rated according to the Harrington’s scale of desirability as ‘satisfactory’ by the third component of the estimation, but the highest numerical values of the level of balance belonged to mare’s milk. To optimize this indicator, the authors recommend livestock animal milk as an ingredient of complex raw commodity products.
In the country today, with the intensive development of production, the development and implementation of waste-free or low-waste technologies is an acute problem. The search for new raw materials and natural biologically active substances is very relevant for any branch of agriculture. Now the state of the food processing industry in Kazakhstan requires addressing the issues of waste disposal, including waste from brewing production. The processing of the main waste of brewing production increases the raw material reserves of the feed base of the agricultural complex and contributes to the preservation of the environment from pollution. The article examines the properties of beer hill, the possibility of its use in the production of compound feeds as the main raw material. The results of experimental studies have proved that the beer slide contains 21.5% protein and 12.7% fat. This is 2 times higher than the grain of barley. Work was also carried out to identify fungal pathogens and producers of toxins contained in the beer bard. As a result, they were not detected. In addition, we have made sure that the raw materials meet the safety requirements in all respects and it is possible to add it to feed mixtures as feed. This brings economic benefits in the production of compound feeds, being an additional valuable protein product.
