Description

Technical Field

[0001] The invention relates to the technical field of food and beverage, and in particular to a milk mineral salt composite polypeptide solid beverage and a preparation method thereof. Background Art

[0003] The aging process of the human body is accompanied by the gradual degeneration of the functions of various tissues and organs. This degeneration is mainly caused by the reduction of basic substances (such as collagen) that constitute these tissues and organs and cell aging. Therefore, supplementing specific nutrients through diet can effectively support the repair of tissues and organs, delay the aging process, and thus improve the quality of life of the elderly.

[0004] However, most current foods and beverages focus on the role of a single peptide ingredient in promoting tissue and organ repair, but rarely involve the evaluation of the effects of using multiple peptide ingredients in combination. They also often ignore the common characteristics of the elderly, such as weakened digestive system function and low calcium absorption efficiency, and fail to provide a fully optimized source of calcium.

[0005] Therefore, it is of great significance to develop a milk mineral salt composite polypeptide solid beverage that promotes the repair of human tissues and organs, is suitable for the elderly to resist aging, improve osteoporosis, and enhance immunity. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a milk mineral salt composite polypeptide solid beverage and a preparation method thereof.

[0007] In a first aspect, the present invention provides a milk mineral salt composite polypeptide solid beverage, comprising protein, milk mineral salt and sugar-containing compounds, wherein the protein is selected from one or more of bovine collagen peptides, fish collagen peptides, chicken collagen peptides, marine collagen peptides, hydrolyzed whey protein, hydrolyzed soy protein, hydrolyzed casein and hydrolyzed wheat protein, and the milk mineral salt is selected from one or more of calcium phosphate, calcium carbonate, calcium citrate, potassium phosphate and zinc sulfate.

[0008] In the present invention, the protein is preferably bovine collagen peptide and hydrolyzed whey protein, and the milk mineral salt is preferably calcium phosphate.

[0009] In the present invention, the protein content of bovine collagen peptides must reach more than 85%, the hydroxyproline content is about 10%, the average molecular weight is close to 1000 DAL, the protein content of hydrolyzed whey protein exceeds 80%, the degree of hydrolysis is controlled between 30% and 40%, the proportion of branched-chain amino acids is not less than 20%, and in the hydrolyzed protein, the proportion of oligopeptides with a molecular weight between 189 and 500 is at least 50%.

[0010] In the present invention, the combination of bovine collagen peptides and hydrolyzed whey protein provides a high-quality protein source, is easy to digest and absorb, and can quickly supplement the amino acids required by the human body, which is especially important for muscle repair and growth. By selecting calcium phosphate as the milk mineral salt, it can provide the calcium and other minerals required by the human body. The hydroxyproline in the bovine collagen peptides helps to transport calcium, while calcium phosphate provides the necessary mineral components for bones. The two work together to promote the healthy development and maintenance of bones, especially for the prevention and treatment of osteoporosis. The amino acids provided by the bovine collagen peptides are essential for the synthesis of bone collagen. Bone collagen and calcium phosphate together constitute the main structure of the bone, which is very important for maintaining bone strength and elasticity.

[0011] Preferably, the sugar-containing compound is selected from one or more of fructooligosaccharides, inulin, isomalto-oligosaccharides, galacto-oligosaccharides and xylo-oligosaccharides.

[0012] In the present invention, the sugar-containing compound is preferably oligofructose, and the purity of the oligofructose powder is not less than 95%.

[0013] In the present invention, oligofructose can selectively promote the growth of beneficial bacteria (such as bifidobacteria and lactic acid bacteria) in the intestine, inhibit the reproduction of harmful bacteria, thereby maintaining the balance of intestinal microecology and improving intestinal health. Oligofructose helps to soften stool, increase stool volume, promote intestinal peristalsis, effectively prevent and relieve constipation problems, and improve intestinal function. Oligofructose can reduce the levels of total cholesterol and low-density lipoprotein (LDL) cholesterol in serum, which helps prevent cardiovascular diseases. Oligofructose has a positive effect on the prevention and treatment of hyperlipidemia by regulating intestinal flora, improving lipid metabolism, and lowering blood lipid levels. Oligofructose can promote the intestinal absorption of minerals such as calcium, magnesium, and iron, especially in the colon. This is especially important for bone health and helps prevent osteoporosis and other mineral deficiency-related diseases. Oligofructose can promote the growth of beneficial bacteria in the intestines, which can synthesize B vitamins, thereby improving the body's absorption and utilization of these vitamins and enhancing the body's metabolic function. Oligofructose can reduce the accumulation of toxins in the body by regulating intestinal flora, prevent and improve skin diseases caused by toxins in the body, such as facial acne, dark spots, freckles, acne, age spots, etc. Oligofructose helps improve skin luster and elasticity, reduce the appearance of fine lines and wrinkles, make the skin more bright, and delay the aging process of the skin. Oligofructose helps reduce inflammatory responses in the intestines and has a certain auxiliary effect in preventing and alleviating chronic inflammatory diseases.

[0014] Preferably, the mass ratio of the protein, emulsifier salt and sugar-containing compound is (40-60):(5-10):(35-50).

[0015] Preferably, the milk mineral salt complex polypeptide solid beverage also includes nutrients, regulators and flavoring agents.

[0016] Preferably, the nutrients are one or more of vitamin C, calcium ascorbate, vitamin E, and bioflavonoids.

[0017] In the present invention, vitamin C is preferably used as the nutrient.

[0018] In the present invention, vitamin C is an indispensable cofactor in the process of collagen synthesis. Prolyl hydroxylase needs to be activated by vitamin C to catalyze the hydroxylation of proline into hydroxyproline, and then synthesize collagen. Collagen is an important component of tissues such as skin, bones, and blood vessels, and is crucial to maintaining the structure and function of these tissues. Vitamin C is a powerful antioxidant that can neutralize free radicals, reduce the damage of oxidative stress to skin cells, prevent skin aging, and reduce the formation of wrinkles and spots. Vitamin C can accelerate wound healing, promote the regeneration and repair of skin cells, and has a significant effect on postoperative recovery and trauma repair. Vitamin C can enhance the function of the immune system, improve the body's resistance to viruses and bacteria, and reduce the occurrence of colds and other infectious diseases. Vitamin C can reduce the levels of total cholesterol and low-density lipoprotein (LDL) cholesterol in serum, and increase the level of high-density lipoprotein (HDL) cholesterol, thereby reducing the risk of cardiovascular diseases. Vitamin C can enhance the elasticity of blood vessel walls, prevent blood vessel rupture and thrombosis, and maintain the health of the cardiovascular system.

[0019] Preferably, the regulator is selected from one or more of sucralose, aspartame, acesulfame potassium, steviol glycosides, and neotame.

[0020] In the present invention, the regulator is preferably sucralose.

[0021] In the present invention, sucralose has a pure, natural sweetness without bitterness or other unpleasant aftertastes, and can significantly improve the taste of the product. Sucralose has good stability under high temperature and acidic conditions, is not easy to decompose, and has good solubility in water, so that the product is more uniform when brewed and has a better taste. Sucralose will not be metabolized by the human body and will not affect blood sugar levels. It is suitable for use by diabetic patients and people who need to control blood sugar.

[0022] Preferably, the flavoring agent is selected from one or more of yeast β-glucan, shiitake β-glucan, ganoderma β-glucan, and wolfberry β-glucan.

[0023] In the present invention, the flavoring agent is preferably yeast β-glucan.

[0024] In the present invention, yeast β-glucan can activate macrophages, NK cells and T cells in the immune system, enhance the body's immune function, and improve resistance to viruses, bacteria and other pathogens. Yeast β-glucan can enhance the body's defense against infection and viruses, reduce the occurrence of infectious diseases, and has a positive effect on the prevention and auxiliary treatment of viral infections (such as influenza). Yeast β-glucan can reduce the total cholesterol and low-density lipoprotein (LDL) cholesterol levels in serum and increase the high-density lipoprotein (HDL) cholesterol level, thereby improving blood lipid conditions and reducing the risk of cardiovascular diseases. Yeast β-glucan can promote wound healing, accelerate tissue repair and regeneration, reduce inflammatory reactions, and shorten healing time. By promoting the synthesis and deposition of collagen, yeast β-glucan helps to reduce the formation of scars and makes the skin smoother after wound healing.

[0025] In a second aspect, the present invention provides a method for preparing a milk mineral salt composite polypeptide solid beverage as described in the first aspect, comprising the following steps:

[0026] S1. Weighing proteins, milk mineral salts and sugar-containing compounds, nutrients, regulators and flavoring agents;

[0027] S2, using a three-dimensional mixer to stir and mix the components evenly;

[0028] S3, crushing the mixed materials through a sieve;

[0029] S4. Granulate the crushed material and use an automatic packaging machine to bag and package it to obtain a milk mineral salt complex polypeptide solid beverage.

[0030] Preferably, in step S2, the stirring speed is 2500-3500 rpm / min.

[0031] Preferably, in step S3, the sieve size is 70-90 mesh.

[0032] Among them, the mass ratio of milk mineral salt complex polypeptide solid beverage is: bovine collagen peptide 2.66-4g, oligofructose powder 2.30-3.285g, hydrolyzed whey protein 1.34-2g, milk mineral salt 0.5-1g, vitamin C 0.05-0.10g, yeast β-glucan 0.05-0.1g, sucralose 0.001-0.005g, edible flavor 0.01-0.002g.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] (1) The small molecule peptide of the present invention can be directly absorbed by the intestine and enter the blood circulation system, which can quickly replenish the amino acids required by the human body and is essential for repairing damaged tissues, promoting muscle growth and maintaining normal physiological functions.

[0035] (2) The yeast β-glucan of the present invention can activate immune cells such as macrophages and NK cells, thereby enhancing the body's nonspecific immune function and improving the body's resistance to diseases.

[0036] (3) The milk mineral salt composite polypeptide solid beverage of the present invention can promote mineral absorption and maintain bone health, while oligofructose can not only regulate intestinal health, but also promote the absorption of minerals such as calcium, which helps prevent osteoporosis and maintain bone health.

[0037] (4) The vitamin C of the present invention is a powerful antioxidant that can remove free radicals in the body, reduce the damage of oxidative stress to cells, protect cells from damage, and promote the synthesis of collagen, which helps the skin maintain elasticity and delays the aging process.

[0072] Solubility test of milk mineral salt complex polypeptide solid beverage: Use a magnetic stirrer to stir the sample evenly for 2-5 minutes, filter the solution with filter paper, check whether there are undissolved particles on the filter paper, and record the weight of the residue on the filter paper. Solubility calculation: Solubility = [(total weight of sample - weight of residue on filter paper) / total weight of sample] * 100%;

[0073] Protein test for milk mineral salt complex polypeptide solid beverage: weigh the sample, add concentrated sulfuric acid and catalyst, heat and digest in a digestion furnace to decompose the organic matter, cool it, add distilled water to dilute it, use a distillation device to distill out the ammonia, absorb it with boric acid solution, titrate the absorption liquid with standard acid solution, calculate the nitrogen content, and calculate the protein content based on the nitrogen content.

[0074] Carbohydrate test of milk mineral salt complex polypeptide solid beverage: The carbohydrate content of milk mineral salt complex polypeptide solid beverage was determined by Fehling's reagent method.

[0075] The performance of Examples 1-5 and Comparative Examples 1-9 was tested, and the test results are shown in Table 1.

[0076] Table 1

[0077]

[0078] From the results in Table 1, we can see that:

[0079] Solubility: The solubility of Examples 1 to 5 is relatively high, ranging from 95.7% to 97.4%, which indicates that the milk mineral salt complex polypeptide solid beverage has good solubility.

[0080] The solubility of Comparative Examples 1 to 9 is significantly lower than that of the embodiment group, especially Comparative Example 1 (68.4%) and Comparative Example 2 (60.2%), where bovine collagen peptides and hydrolyzed whey protein were removed, respectively, resulting in a significant decrease in solubility.

[0081] Protein content: The protein content of Examples 1 to 5 is between 18.5% and 20.4%, showing a relatively stable protein level. The protein content of Comparative Examples 1 to 9 is generally lower than that of the Example Group, especially Comparative Example 1 (14.5%) and Comparative Example 2 (13.4%). Removing components affects the nutritional value of the product.

[0082] Carbohydrate content: The carbohydrate content of Examples 1 to 5 was between 37.5% and 38.6%, maintaining a relatively high carbohydrate level. The carbohydrate content of Comparative Examples 1 to 9 fluctuated, but was generally lower than that of the Example group, Comparative Example 3 (25.4%) and Comparative Example 4 (24.6%), in which oligofructose and calcium phosphate were removed, respectively, resulting in a significant reduction in carbohydrate content.

[0083] Bovine collagen peptides and hydrolyzed whey protein are essential for improving the solubility and protein content of the product. Oligofructose not only helps to increase the carbohydrate content of the product, but may also affect the solubility of the product. The addition of calcium phosphate can improve the solubility and nutritional structure of the product.

[0084] The specific embodiments further describe the present invention, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
