Description

Technical Field

[0001] The present invention belongs to the technical field of biological food, and in particular relates to a compound hydrolyzed whey protein powder capable of preventing sarcopenia and a preparation method thereof. Background Art

[0002] Sarcopenia is the natural decrease in muscle mass with age. Typical symptoms include muscle atrophy (such as thinning limbs and decreased grip strength), physical decline (slow walking and difficulty getting up), and fatigue. Early intervention can improve the condition through nutritional supplements and regular exercise.

[0003] Hydrolyzed whey protein is a protein that can enhance human physiological functions. Whey protein is enzymatically broken down into smaller peptide chains or amino acid forms, reducing its molecular weight (the molecular weight of hydrolyzed whey protein is typically 500-5000 Daltons). Advantages of hydrolyzed whey protein: 1. High absorption efficiency: The small molecule structure can be absorbed by the intestines without complex digestion, making it suitable for infants, the elderly, or people with weak digestive functions. 2. Removing allergens while retaining nutrients: The hydrolysis process destroys allergenic components such as β-lactoglobulin in whey protein, reducing the risk of allergies. The key amino acids (such as branched-chain amino acids BCAA) and bioactive peptides of hydrolyzed whey protein are still retained, maintaining its nutritional value. 3. Hydrolyzed whey protein can quickly replenish protein after exercise and promote muscle repair.

[0004] Existing commercially available products claiming muscle-building effects have diverse and complex ingredient compositions, and in-depth research into the core ingredients responsible for these effects is lacking. This is primarily reflected in the lack of in-depth study of the relationship between active substances with significant muscle-building effects and their effective dosages. Regarding muscle-building effects, existing patents for hydrolyzed whey protein remain at the stage of final product development, application, and efficacy verification, lacking in-depth analysis of the efficacy of hydrolyzed whey protein powder raw materials or compounded hydrolyzed whey protein powders. Furthermore, research into compounded hydrolyzed whey protein powders in animal experiments and clinical trials is limited. Summary of the Invention

[0005] The object of the present invention is to provide a compound hydrolyzed whey protein powder and a preparation method for preventing sarcopenia, so as to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A compound hydrolyzed whey protein powder for preventing sarcopenia comprises hydrolyzed whey protein A, hydrolyzed whey protein B, hydrolyzed whey protein C, hydrolyzed whey protein D, hydrolyzed whey protein E, hydrolyzed whey protein F, hydrolyzed whey protein G and hydrolyzed whey protein H.

[0011] Furthermore, in any one type of whey protein hydrolysate, the proportion of whey protein hydrolysate greater than 10,000 Daltons does not exceed 55%.

[0022] The technical solutions of the present invention are described in detail below through examples. The following examples are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and cannot be interpreted as limiting the technical solutions of the present invention.

For the hydrolyzed whey proteins A and H, different brands or the same brand can be selected. The key lies in the total branched-chain amino acid content and the molecular weight below 1000 Daltons in the hydrolyzed whey proteins. The above-mentioned hydrolyzed whey proteins A and H in the present application are all commercially available.

[0024] In the present application, the content of each hydrolyzed whey protein in the compound hydrolyzed whey protein powder is 5%-40% by weight, and the total amount is 100%.

[0025] In the present application, the total branched-chain amino acid content in 100g of hydrolyzed whey protein A is 13.22g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein B is 18.39g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein C is 18.39g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein D is 19.47g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein E is 17.87g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein F is 18.39g, the total branched-chain amino acid content in 100g of hydrolyzed whey protein G is 23.75g, and the total branched-chain amino acid content in 100g of hydrolyzed whey protein H is 13.41g.
