Abstract: This paper aims to explore in depth the application of camel milk in health products. Through a detailed elaboration of the nutritional components, bioactive substances and health care effects of camel milk, combined with the current relevant research results and market application situations, it analyzes the challenges faced by camel milk in the development of health products and looks forward to its future development prospects, so as to provide a reference basis for further research and industrialization of camel milk in the field of health products. A. Introduction With the continuous improvement of people's health awareness, the demand for health products is increasing day by day. Traditional sources of health products have been difficult to meet consumers' expectations for natural, highly efficient and multifunctional products. Camel milk, as a natural product with unique nutritional components and bioactive substances, has gradually become a research hotspot in the field of health products. Camels survive in harsh desert environments, and the camel milk they secrete has the characteristics of adapting to special environments and may contain components of great significance to human health, which provides broad prospects for the development of new types of health products. B. Nutritional Components of Camel Milk Camel milk is rich in a variety of nutrients. It is abundant in protein and contains multiple essential amino acids, such as lysine, leucine and so on. These amino acids play a crucial role in human growth and development, tissue repair and immune regulation. Compared with cow milk, the protein in camel milk differs in amino acid composition and structure and has a higher nutritional value. In terms of fat, the fat globules in camel milk are relatively small, making it easy to digest and absorb. Meanwhile, it has a relatively high content of unsaturated fatty acids, especially polyunsaturated fatty acids essential for the human body, like linoleic acid and linolenic acid, which are helpful in reducing cholesterol levels and preventing cardiovascular diseases. Camel milk also contains abundant minerals, including calcium, phosphorus, potassium, sodium, iron, zinc and so on. Among them, calcium is present in a relatively high amount and has a good bioavailability, which is of great significance for maintaining bone health. In addition, camel milk has a complete variety of vitamins, such as vitamin A, vitamin D, vitamin E, vitamin C and B vitamins. These vitamins play an indispensable role in antioxidant activities, regulating metabolism and maintaining visual functions. C. Bioactive Substances in Camel Milk Immunoglobulin Camel milk contains immunoglobulin, and particularly, the content of IgG is relatively high. These immunoglobulins can recognize and bind to pathogens, strengthening the body's immune defense ability and helping to prevent and resist infectious diseases. Research has shown that the immunoglobulins in camel milk possess a certain degree of stability in the intestine and can play an immunomodulatory role on the surface of the intestinal mucosa, thus promoting intestinal health. Lactoferrin Lactoferrin is an iron-binding protein with multiple biological functions. In camel milk, lactoferrin can not only regulate the absorption and utilization of iron and prevent oxidative damage caused by iron overload, but also possess activities such as antibacterial, antiviral, anti-inflammatory and immunomodulatory effects. It can inhibit the growth and reproduction of bacteria and viruses by binding to the receptors on their surfaces, and at the same time activate the body's immune cells to enhance the immune response. Lysozyme Lysozyme is another important bioactive substance in camel milk. It can hydrolyze peptidoglycan in the cell walls of bacteria, leading to the lysis and death of bacteria, and has broad-spectrum antibacterial activity. The presence of lysozyme in camel milk helps maintain the microbial stability of camel milk and also provides an antibacterial and immunomodulatory functional basis for its application in health products. Insulin-like Growth Factor (IGF) Camel milk contains a certain amount of insulin-like growth factor, which is closely related to human growth and development, cell proliferation and differentiation. IGF can stimulate the growth of muscle cells and bone cells and promote protein synthesis, having potential benefits for children's growth and development as well as adults' body repair and maintenance of muscle mass. In addition, IGF also plays a role in regulating blood glucose levels and improving insulin sensitivity, and may have a certain adjuvant therapeutic effect on metabolic diseases such as diabetes . D. Health Benefits of Camel Milk Immunomodulatory Effect The bioactive substances in camel milk, such as immunoglobulins, lactoferrin, and lysozyme, work synergistically and can significantly enhance the body's immune function. Multiple studies have shown that long-term consumption of camel milk can increase the levels of immunoglobulins in the body, boost the activity of immune cells, strengthen the body's resistance to pathogens, and reduce the occurrence frequency and severity of infectious diseases. For example, in some clinical trials, after people with low immunity were given camel milk to drink for a period of time, it was found that the contents of immunoglobulin G (IgG) and immunoglobulin A (IgA) in their sera were significantly increased, and the incidence of respiratory tract infectious diseases such as colds and flu was significantly reduced. Intestinal Health Promotion Effect Camel milk has multiple benefits for intestinal health. Its protein and fat have relatively high digestion and absorption rates and are less likely to cause gastrointestinal burden. Meanwhile, the immunoglobulins and lactoferrin in camel milk can regulate the balance of intestinal flora, inhibit the growth of harmful bacteria and promote the proliferation of beneficial bacteria. Research has found that camel milk can increase the number of beneficial bacteria such as bifidobacteria and lactobacilli in the intestine, reduce the proportion of harmful bacteria such as Escherichia coli, and improve the intestinal microecological environment. In addition, the bioactive substances in camel milk also have anti-inflammatory effects, which can alleviate intestinal inflammatory reactions and prevent and treat intestinal diseases such as inflammatory bowel disease (IBD). Antioxidant Effect The antioxidant nutrients rich in camel milk, such as vitamin C, vitamin E and selenium, as well as bioactive substances like lactoferrin and lysozyme, possess relatively strong antioxidant capacities. These components can scavenge free radicals in the body, reduce the damage to cells caused by oxidative stress, and prevent the occurrence of chronic diseases such as aging, cancer and cardiovascular diseases. Experimental studies have shown that the antioxidant substances in camel milk can reduce the content of malondialdehyde (MDA), a lipid peroxidation product, and increase the activities of antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GSH - Px), thus protecting cells from oxidative damage. Adjuvant Therapeutic Effect on Diabetes As camel milk contains insulin-like growth factor (IGF) and some bioactive substances with the function of regulating blood glucose, such as lactoferrin, it shows certain potential in the adjuvant treatment of diabetes. Research has found that camel milk can improve blood glucose control in diabetic patients, reduce fasting blood glucose and postprandial blood glucose levels, and enhance insulin sensitivity. The mechanism of action may be related to the fact that the active ingredients in camel milk can promote the secretion of insulin, regulate the activities of enzymes related to glucose metabolism and alleviate insulin resistance. However, it should be noted that camel milk cannot replace the conventional drug treatment for diabetes and can only be used as an auxiliary means for the comprehensive management of diabetes. Preventive Effect on Cardiovascular Diseases Components in camel milk such as unsaturated fatty acids, lactoferrin and vitamins have a positive impact on cardiovascular health. Unsaturated fatty acids help to reduce the levels of cholesterol and triglycerides in the blood and decrease the risk of atherosclerosis. Lactoferrin can inhibit the oxidative modification of low-density lipoprotein (LDL) and reduce the damage to vascular endothelial cells caused by oxidized LDL, thereby preventing the occurrence of cardiovascular diseases. In addition, minerals such as potassium and magnesium in camel milk contribute to maintaining normal cardiac rhythm and stable blood pressure. Clinical studies have shown that long-term consumption of camel milk can reduce the morbidity and mortality of cardiovascular diseases and improve the prognosis of patients with cardiovascular diseases. E. Forms of Application of Camel Milk in Health - care Products Camel Milk Powder Camel milk powder is currently the most common form of camel milk health products on the market. Fresh camel milk is processed through techniques such as concentration and drying to make camel milk powder. This not only facilitates storage and transportation but also can better preserve the nutritional components and bioactive substances in camel milk. Camel milk powder can be directly mixed with water for drinking and is suitable for different age groups and consumer groups. It is especially a convenient option for people who have difficulty obtaining fresh camel milk. Camel Milk Tablets Camel milk tablets are sheet-like products made by pressing with camel milk powder as the main raw material and adding an appropriate amount of auxiliary materials such as sucrose and starch. Camel milk tablets have the characteristics of good taste and convenient consumption. They can be eaten as snacks or daily nutritional supplements. During the processing, it is necessary to pay attention to controlling the amount of auxiliary materials added and the processing technology to ensure that camel milk tablets can retain the nutrition and efficacy of camel milk to the greatest extent. Camel Milk Oral Liquid Camel milk oral liquid is a liquid dosage form made by subjecting camel milk to processes such as extraction, concentration and blending. The advantage of this dosage form is its fast absorption and high bioavailability, enabling it to play the health care role of camel milk more quickly. Camel milk oral liquid usually adds some auxiliary ingredients such as vitamins and minerals to enhance its health care efficacy. However, due to its liquid state, attention should be paid to hygiene and stability issues during storage and transportation. Compound Preparations of Camel Milk Health Products In order to further enhance the efficacy of camel milk health products, some enterprises combine camel milk with other raw materials with health care functions, such as probiotics and Chinese herbal extracts, to develop compound preparations of camel milk health products. For example, combining camel milk with probiotics such as Bifidobacterium and Lactobacillus acidophilus can enhance the intestinal regulation function; combining it with Chinese herbal extracts such as wolfberries and astragalus can play a synergistic role in antioxidant and immunomodulatory effects. Such compound preparations can integrate the advantages of multiple raw materials and meet consumers' demands for multi-functional health products. F. Challenges in the Development of Camel Milk Health Products Milk Source Supply and Quality Control The breeding scale of camels is relatively small and their distribution is rather scattered, which leads to a relatively limited supply of camel milk as a milk source. Compared with traditional milk sources like cow milk, the yield of camel milk is lower and it is difficult to meet the demands of large-scale industrial production. In addition, due to differences in the breeding environments and feeding management methods of camels, the quality of camel milk also fluctuates to some extent. During the development of camel milk health products, how to establish a stable milk source supply system and ensure the quality, safety and consistency of camel milk is one of the important challenges faced. Processing Technology and Process Optimization The nutritional components and bioactive substances in camel milk are rather special and are prone to denaturation or inactivation under the influence of factors such as temperature, pressure and light during the processing. At present, although there are already some camel milk processing technologies and processes, they still need to be further optimized and improved to enhance the quality and efficacy of camel milk health products. For example, in the production process of camel milk powder, how to maximize the retention of active components such as immunoglobulins and lactoferrin in camel milk while ensuring the drying effect is a problem that requires in-depth research. Product Standards and Regulatory System Currently, the product standards and regulatory system for camel milk health products are still not perfect. Compared with dairy products made from cow milk, there are fewer national and industry standards related to camel milk health products, which results in uneven quality of camel milk health products on the market and makes it difficult for consumers to distinguish between good and bad products. Establishing and improving the product standards and regulatory system for camel milk health products and strengthening the supervision of the production, processing and sales links of camel milk health products are the keys to safeguarding consumers' rights and interests and promoting the healthy development of the camel milk health products industry. Consumer Awareness and Market Promotion Although camel milk has certain potential in the field of health products, consumers' awareness of camel milk is currently relatively low. Many consumers lack an understanding of the nutritional components, health care effects and product forms of camel milk, which restricts the market promotion and sales of camel milk health products. Therefore, it is necessary to strengthen the publicity and promotion of camel milk health products, improve consumers' awareness and acceptance, and expand the market for camel milk health products through scientific 19 publicity and effective marketing strategies. G. Development Prospects of Camel Milk in the Field of Health Products Although camel milk faces numerous challenges in the process of developing health products, its development prospects remain broad with the continuous progress of science and technology and the constant improvement of people's health awareness. In terms of scientific research, as the research on the nutritional components and bioactive substances in camel milk continues to deepen, it is expected that more components with health care functions will be discovered and their action mechanisms will be revealed. This will provide a theoretical basis for the development of new and highly effective camel milk health products. For example, recent studies have found that some small molecular peptides in camel milk have biological activities such as antioxidant and blood pressure-lowering effects. In the future, it is expected that these small molecular peptides will be developed into products with specific health care functions. In terms of industrial development, with the improvement of camel breeding techniques and the expansion of breeding scale, the supply of camel milk as a milk source will gradually increase, providing a guarantee for the large-scale production of camel milk health products. Meanwhile, the continuous innovation and optimization of processing technologies will improve the quality and efficacy of camel milk health products and reduce production costs. In addition, with the continuous growth of consumers' demand for health products and the increase in their awareness of camel milk, the market for camel milk health products is expected to enter a period of rapid development. In terms of market application, the application forms of camel milk health products will become more diversified. Besides the existing product forms such as camel milk powder, camel milk tablets and camel milk oral liquid, more personalized and specialized products may be developed in the future, such as camel milk health products targeted at specific groups of people (such as the elderly, children, athletes, etc.), and compound products combined with other health products (such as functional foods, medical devices, etc.). To sum up, camel milk has great application potential in the field of health products. By overcoming the challenges in aspects such as milk source supply, processing technology, product standards and consumer awareness, and giving full play to the advantages of its nutritional components and bioactive substances, camel milk health products are expected to become a bright star in the future health industry and make greater contributions to human health and well-being. Conclusion Camel milk, as a natural product with unique nutritional components and bioactive substances, exhibits remarkable health benefits in the field of health products, such as immunomodulation, promotion of intestinal health, antioxidant effects, and adjuvant treatment for diabetes and cardiovascular diseases. Currently, camel milk has been developed into various forms of health products, such as camel milk powder, camel milk tablets, camel milk oral liquid and compound preparations. However, during the development process, it still faces challenges in aspects such as milk source supply, processing technology, product standards and consumer awareness. Nevertheless, with the deepening of scientific research, the development of the industry and the expansion of the market, the development prospects of camel milk in the field of health products are extremely broad. In the future, it is necessary to further strengthen the research and development of camel milk, improve relevant product standards and regulatory systems, and enhance consumer awareness, so as to promote the healthy and sustainable development of the camel milk health products industry and enable more consumers to benefit from this natural health treasure of camel milk.
