Description

Technical Field

[0001] This invention relates to the field of muscle-building and bone health products, specifically to a protein powder with dual health functions of increasing muscle and bone density, its preparation method, and its application, applicable to sports nutrition, health care for middle-aged and elderly people, and postoperative rehabilitation. Background Technology

[0002] With increasing health awareness, protein supplements are being used more and more widely among athletes, the elderly, and rehabilitation patients. However, existing protein powder products have limited functionality and cannot simultaneously meet the needs of muscle growth and bone health. For example, athletes often face bone calcium loss during muscle building, while the elderly need to combat both muscle loss and osteoporosis. In addition, existing protein powders have shortcomings in terms of taste, mixing uniformity, and reconstitution properties. For example, calcium β-hydroxy-β-methylbutyrate (CaHMB) has a bitter taste, and the mineral ingredients have a gritty texture, which limits the widespread application of these products.

[0003] Protein powder: Protein not only promotes tissue growth and repair but also provides ample energy. Whey protein and soy protein are excellent choices for sports nutrition. They contain branched-chain amino acids and functional peptides, which can relieve muscle soreness, repair sports injuries, and improve muscle mass. Compared to casein, whey protein is more effective for skeletal muscle synthesis, helps with weight management, prevents immune imbalance caused by over-exercise, enriches serum globulins, and regulates immune stress. Appropriate supplementation with this type of nutrient during exercise can enhance athletic performance and the body's repair capabilities, leading to better athletic performance. Meanwhile, protein is also crucial for maintaining bodily functions in middle-aged and elderly individuals. Whey protein and soy protein are easily absorbed and are ideal nutritional supplement choices. They contain high-quality amino acids and immunoglobulins, which can slow muscle loss, repair body tissues, improve the physical condition of middle-aged and elderly individuals, enhance immunity, reduce the risk of infection, and help maintain a healthy weight, alleviating discomfort caused by physical decline. Appropriate daily supplementation can help middle-aged and elderly individuals maintain vitality and improve their quality of life.

[0004] Calcium β-hydroxy-β-methylbutyrate: Maintaining muscle mass and strength is crucial for ensuring systemic protein metabolism, wound healing, organ function, skin integrity, and immune function, while also enhancing physical reserves. Studies show that β-hydroxy-β-methylbutyrate (HMB) promotes muscle protein synthesis and slows muscle protein breakdown by both upregulating protein synthesis signaling pathways and downregulating protein breakdown signaling pathways. Research has measured fasting plasma HMB concentrations in people of different ages, showing that plasma HMB concentrations decrease with age, with children having the highest average HMB concentration, followed by young adults and the elderly. Furthermore, plasma HMB concentrations in adults show a significant positive correlation with muscle mass and strength. Calcium β-hydroxy-β-methylbutyrate (CaHMB), a new resource food ingredient, is one of the common supplemental forms of HMB and is widely used in food. Its applications include animal nutrition, sports nutrition, and special medical purpose formula foods. The application of CaHMB is mainly based on its ability to promote muscle synthesis and reduce muscle protein degradation. In sports nutrition, CaHMB can promote muscle volume increase, increase muscle strength, and improve muscle repair after exercise.

[0005] Calcium: Calcium is an essential macroelement for the human body, its core function being to build strong bones and teeth, and maintaining key physiological functions such as nerve conduction, muscle contraction, and blood clotting. Organic calcium is a superior supplementation choice, as it is gentle on the stomach and does not rely on stomach acid. Its absorption rate is much higher than inorganic calcium, and it does not cause discomfort such as bloating or constipation, making it suitable for long-term supplementation by all types of people. For athletes, calcium can increase bone density, strengthen bone resilience, aid muscle contraction and energy metabolism, reduce the risk of bone injury and muscle cramps during exercise, improve muscle endurance, prevent decreased athletic performance due to calcium deficiency, maintain normal neuromuscular excitability, and make athletic performance more stable. For middle-aged and elderly people, calcium can slow bone loss, prevent osteoporosis, reduce the risk of fractures, maintain cardiovascular stability, and relieve discomfort such as limb numbness and muscle soreness. Appropriate daily supplementation can help athletes improve athletic performance and reduce the probability of injury, and also help middle-aged and elderly people consolidate bone health, maintain physical activity, and improve quality of life.

[0006] Patent CN107440126A discloses a protein powder for relieving exercise fatigue, but it mainly focuses on anti-fatigue and muscle building, without addressing bone health protection. While patent CN108651998A adds multiple functional ingredients, its formula is complex and the taste issue remains unresolved. Therefore, there is an urgent need to develop a protein powder with a scientifically formulated and optimized process to fill the market gap for the combined needs of "muscle + bone."

[0007] Currently, the market supply of nutritional supplements specifically for sarcopenia is insufficient. Existing nutritional compositions designed to improve muscle function and endurance generally contain fats, casein, and organic acid salts containing trace elements such as potassium, sodium, and phosphorus. These components play multiple roles in the products. However, for older adults with declining digestive and metabolic functions, especially those with sarcopenia, the presence of these components poses significant health risks. Given these issues, there is an urgent market need for a functional food product specifically designed for older adults with sarcopenia. This product should possess the following characteristics: ① Reduce gastrointestinal burden: Avoid ingredients that may increase digestive and metabolic burden, such as high-sodium, high-phosphorus organic acid salts, casein, and fat. ② Maintain muscle health: Provide easily absorbed protein and other nutrients through a scientifically formulated approach to support muscle synthesis and repair. ③ Prevent and improve sarcopenia: Help older adults maintain muscle function and endurance through a balanced combination of nutrients, slowing down the progression of muscle loss. In conclusion, developing a nutritional supplement suitable for older adults with sarcopenia is not only of significant health importance but also meets market demand. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide a protein powder with dual health functions of increasing muscle and bone density, as well as its preparation method and applications. This protein powder, through scientific formulation, is a functional protein powder that combines calcium and calcium β-hydroxy-β-methylbutyrate (CaHMB), and is particularly suitable for sports nutrition, health care for middle-aged and elderly people, and postoperative rehabilitation.

[0009] To achieve the above objectives, the first aspect of the present invention provides a protein powder with dual health functions of increasing muscle and bone density, comprising the following components by weight: 30-40 parts whey protein, 25-35 parts soy protein isolate, 1-10 parts calcium β-hydroxy-β-methylbutyrate (CaHMB), 1-10 parts calcium salt, 8-20 parts resistant dextrin, 0.5-1.5 parts suspending agent, 0.1-1 part sweetener, and 0.3-3 parts edible flavoring.

[0010] In this invention, both whey protein and soy protein isolate are high-quality proteins, whose core functions are to supplement the amino acids needed by the human body, aid in muscle synthesis and repair, and maintain bodily functions. The advantages of whey protein are: rapid absorption, quick energy supply, an amino acid ratio close to human needs, and high utilization rate. The advantages of soy protein isolate are: it contains dietary fiber and plant-based active ingredients, which are beneficial to cardiovascular health.

[0011] Calcium β-hydroxy-β-methylbutyrate reduces post-exercise muscle damage and aids in repair and growth by inhibiting muscle protein breakdown and promoting muscle protein synthesis. It enhances athletic performance and endurance, delays fatigue, and helps maintain muscle mass, making it particularly suitable for fitness enthusiasts and the elderly. It is a high-quality nutritional supplement that balances muscle protection and performance support. When combined with protein powder, calcium β-hydroxy-β-methylbutyrate creates a synergistic effect of "synthesis + protection."

[0012] Calcium plays a vital role in bone and teeth mineralization, maintaining nerve conduction and muscle contraction, and regulating blood clotting. It strengthens bones and teeth, prevents osteoporosis, and ensures normal heartbeat and neuromuscular function, making it crucial for bone health and overall bodily function at all ages. The combination of calcium and protein powder provides the dual health benefits of increased muscle and bone density.

[0013] Resistant dextrin, as a water-soluble dietary fiber, can regulate gut microbiota, promote intestinal motility, control blood sugar and lipids, and increase satiety to aid in weight management. In powder form, it can improve solubility, enhance the taste of instant preparation, and prevent clumping. As a low-calorie filler, it does not affect the absorption of core nutrients, combining nutritional benefits with processing suitability.

[0014] The core function of suspending agents is to prevent the active ingredients from settling and clumping, improve dispersion uniformity, allow powders to dissolve quickly and prevent separation when mixed with water, while also optimizing the smoothness of the taste and ensuring consistent intake of ingredients each time. The application of resistant dextrin and suspending agents solves problems such as the gritty texture of mineral raw materials.

[0015] Sweeteners in powders improve taste, mask off-flavors of raw materials, and are low in calories, so they don't affect blood sugar. Flavorings give powders a pleasant taste and solve the bitterness problem of calcium β-hydroxy-β-methylbutyrate (CaHMB). The combination of these two enhances the eating experience, making the product more acceptable and ensuring consumer compliance.

[0016] The calcium salt includes one of calcium carbonate, calcium citrate, calcium citrate malate, and milk mineral salts.

[0017] The calcium salt has a particle size of 1000-2000 mesh.

[0018] The whey protein includes whey protein concentrate and whey protein isolate, with a protein content greater than 80%.

[0019] The suspending agent includes one of xanthan gum, guar gum, carrageenan, pectin, and maltodextrin.

[0020] The sweetener includes one of steviol glycosides, mogrosides, sucralose, aspartame, and neotame.

[0021] Preferably, a protein powder with dual health functions of increasing muscle and bone density comprises, by weight, the following components: 35-40 parts whey protein, 30-35 parts soy protein isolate, 5-8 parts calcium β-hydroxy-β-methylbutyrate (CaHMB), 4-8 parts milk mineral salt, 10-15 parts resistant dextrin, 1.0-1.2 parts xanthan gum, 0.2-0.5 parts mogroside, and 1-2 parts edible flavor.

[0022] A second aspect of the present invention also provides a method for preparing the protein powder, comprising the following steps.

[0023] Weighing: Accurately weigh each material according to the formula ratio.

[0024] Mixing 1: Add equal amounts of sweetener and resistant dextrin to the mixture twice, mix thoroughly, and obtain Mixture 1.
