[0005] To achieve the above purpose, the present application provides the following technical scheme: a preparation method of an anti-aging bodybuilding nutritional product, comprising the following steps: Step 1: weigh the raw materials according to the weight parts, including tea polyphenols, tea micromolecules, collagen peptide, vitamin E, vitamin C, malt dextrin and erythritol; Step 2: pretreat tea polyphenols and tea micromolecules, dry tea polyphenols in a 30-50℃ vacuum drying oven for 2-3 hours, and filter tea micromolecules through a microporous filter membrane to remove impurities; When filtering tea micromolecules, pass 6 parts of tea micromolecule solution through a 0.22μm microporous filter membrane, control the flow rate at 6mL / min and the pressure at 0.12MPa, and obtain a clear refined liquid after filtration with a transmittance of 97%; Step three: mix the pretreated tea polyphenols and tea micro-molecules with collagen peptide, vitamin E and vitamin C, add deionized water to prepare a mixed solution with a concentration ratio of 20%-30%, and stir at a temperature of 50-60 DEG C and a rotation speed of 200-300 rpm for 1-2 h; Step four: add malt dextrin and erythritol to the mixed solution, continue stirring for 30-50 minutes, and then use a spray drying process, with an inlet temperature of 180-200 DEG C and an outlet temperature of 80-90 DEG C, to obtain a powder-like semi-finished product after drying; The powder-like semi-finished product obtained after drying has a water content of 2.8%, a particle size distribution of 80-120 mu m, a loose bulk density of 0.4 g / cm3, and a yield of 93%; Step five: screen the semi-finished product through an 80-120 mesh screen, remove the caked particles, and then use a tablet press to press into tablets or fill into a capsule shell to obtain the anti-aging and fitness nutritional product.

[0006] By adding collagen peptide, the antioxidant capacity of the product can be increased, the oxidative damage after exercise can be effectively alleviated, cell aging can be delayed, traditional sucrose can be banned, malt dextrin and erythritol can be used as substitutes, it is suitable for long-term consumption by fitness people, and through the targeted pretreatment process and inert gas protection technology, the problems of easy oxidation and activity loss of the core components in the traditional preparation method are solved, so that tea polyphenols and tea micro-molecules and other substances are more easily absorbed and utilized by the human body.

[0007] As a preferred technical solution of the present application, when the raw materials are weighed, the raw material ratio is tea polyphenols 6-10 parts, tea micro-molecules 4-8 parts, collagen peptide 3-5 parts, vitamin E content 0.5-2 parts, vitamin C content 0.3-1.5 parts, malt dextrin 6-12 parts, and erythritol 3-6 parts.

[0008] The above technical solution can make malt dextrin provide sustained-release carbohydrates, erythritol has zero calories and does not cause blood sugar fluctuations, is suitable for long-term consumption by fitness people, and the overall formula not only meets the energy and protein needs after exercise, but also delays cell aging through multi-dimensional antioxidant.

[0009] As a preferred technical solution of the present application, tea polyphenols are extracted from green tea or oolong tea and other tea liquid, the purity is greater than or equal to 95%, the proportion of catechin components is not less than 70%, the extraction process uses supercritical CO2 extraction method, the extraction pressure is controlled to be 30-40 MPa, the extraction temperature is 40-50 DEG C, the CO2 flow is 20-30 L / h, the extraction time is 2-3 h, and purification treatment is required after extraction; The supercritical CO2 extraction method is a low-temperature extraction process, which can effectively avoid the damage of high temperature to catechins, and the catechin retention rate is increased by more than 30% compared with the traditional solvent extraction method; the extraction pressure of 30-40 MPa can ensure that CO2 is in a supercritical state.

[0010] The above technical scheme can protect the catechin active ingredient, and the CO2 flow rate of 20-30 L / h and the extraction time of 2-3 h balance the efficiency and purity, so as to ensure that the purity of the extract is greater than or equal to 95%, and after the purification treatment, the caffeine is further removed, thereby avoiding sleep disturbance of the fitness population caused by caffeine intake.

[0011] As a preferred technical scheme of the present application, the tea micro-molecule is prepared by an ultrahigh pressure homogenization method, the molecular particle size is controlled to be 100-500 nm, and the active ingredient retention rate is greater than or equal to 90% detected by high performance liquid chromatography, wherein the ultrahigh pressure homogenization technology utilizes 100-1000 MPa static or dynamic to uniformly transmit the pressure to the tea raw material system through a liquid medium, to initiate multiple physical effects to realize molecular dispersion. The shear effect caused by high pressure can break the macromolecular groups of the tea extract into small molecules, and the cavitation effect can form micro-bubbles in the liquid, and the impact force generated by the rupture of the bubbles further refines the molecular particle size; finally, the tea micro-molecule with a uniform particle size distribution of 100-500 nm can be directly absorbed through the gap of the intestinal epithelial cells, the absorption rate is increased by more than 80% compared with the non-homogenization treatment, and the active ingredient retention rate is greater than or equal to 90%.

[0012] The above technical scheme can avoid the macromolecular components from being discharged due to the inability to be absorbed; the ultrahigh pressure homogenization technology realizes molecular dispersion of the tea raw material through shear, impact and cavitation and the like, while avoiding the destruction of the active ingredients caused by high-temperature processing.

[0013] As a preferred technical scheme of the present application, the conductivity of the deionized water is less than or equal to 10 mu S / cm, and inert gas protection is adopted during the mixing process to prevent oxidation of the raw materials, and inert gas protection treatment is adopted during the mixing process. In addition to nitrogen, argon can also be selected as the inert gas to increase the protection effect, the gas is filtered through a 0.2 mu m filter membrane before being introduced into the mixing tank to prevent impurity particles carried in the gas from polluting the mixed solution; at the same time, a one-way valve needs to be installed at the exhaust port of the mixing tank to avoid air backflow, so as to ensure that the entire mixing process is in an inert gas atmosphere. The above technical scheme can ensure that the activity of the raw materials is not lost and the purity is not reduced during the preparation process, and the deionized water removes impurity ions to avoid complex reactions between the ions and the tea polyphenols and collagen peptide, thereby ensuring the stability of the active ingredient structure.

[0014] As a preferred technical scheme of the present application, when the mixed solution is subjected to the spray drying process, the feeding speed of the spray drying is 15-25 mL / min, and the atomization pressure is 0.2-0.3 MPa, so as to ensure that the powder particle size is uniform and the particle size distribution is 50-150 mu m. The atomizer of the spray drying adopts a titanium alloy centrifugal atomizing disc, which can avoid metal ion dissolution to contaminate the product; the feeding speed of 15-25 mL / min and the atomizing pressure of 0.2-0.3 MPa need to be matched and adjusted, for example, when the feeding speed is increased to 25 mL / min, the atomizing pressure needs to be increased to 0.3 MPa accordingly, to ensure that the mixed solution forms uniform mist droplets, and to avoid incomplete drying due to too large mist droplets or powder scattering due to too small mist droplets.

[0015] The above technical solution can make the mixed solution form uniform mist droplets during spray drying, avoid powder caking caused by uneven mist droplet size, and ensure excellent powder flowability with a particle size distribution of 50-150 mu m, facilitating subsequent tabletting or capsule filling, and avoiding the presence of large particles.

[0016] As a preferred technical solution of the present application, when the raw materials are weighed, the raw material ratio is tea polyphenol 5-10 parts, tea micro-molecule 5-8 parts, collagen peptide 4-6 parts, vitamin E content 0.5-2 parts, vitamin C content 0.3-1.5 parts, malt dextrin 3-8 parts, and erythritol 2-4 parts.

[0017] The above technical solution can make the formula more suitable for low-sugar and high-protein fitness needs, with the proportion of collagen peptide increased to 4-6 parts, providing more high-quality protein needed for muscle repair, promoting muscle synthesis after exercise, and at the same time enhancing the content of skin collagen, taking into account the muscle growth and anti-aging needs of fitness groups; the total amount of malt dextrin and erythritol is reduced, further reducing calorie intake, suitable for sugar control fitness groups.

[0018] As a preferred technical solution of the present application, the reduction of the content of malt dextrin and erythritol can reduce the sugar content of the fitness nutritional product, and a high proportion of collagen peptide needs to ensure activity, and as a high-protein nutritional ingredient, the activity of collagen peptide is sensitive to temperature and pressure, so its activity needs to be focused on during the preparation process, the temperature is controlled at 45-55 DEG C during the mixing process, and the stirring speed is stabilized at 250-300 rpm, to avoid the breaking of the peptide bond of collagen peptide due to excessive temperature or fluctuation of the stirring speed; To further ensure the activity of collagen peptide, the outlet air temperature needs to be controlled at 80-85 DEG C during the spray drying stage to reduce the damage to the peptide bond caused by high temperature, and the dried powder needs to be sealed and packaged, and an oxygen absorber is placed in the package to prevent oxidation of collagen peptide during storage.

[0019] The above technical solution can avoid excessive local shear force and prevent the breaking of the peptide bond, while ensuring uniform mixing, through precise control of temperature and speed, both low-sugar health needs and the activity of collagen peptide are ensured.

[0020] As a preferred technical scheme of the present application, when tea polyphenols, tea micro-molecules, collagen peptide, vitamin E, vitamin C, malt dextrin and erythritol are mixed and stirred, the content of malt dextrin and erythritol is reduced due to the increase of collagen peptide, so the stirring time needs to be increased by 0.5 h. After stirring is completed, the uniformity of the mixed solution is detected by sampling, and the content deviation of tea polyphenols and collagen peptide in the mixed solution is detected by high performance liquid chromatography, so as to ensure that the content deviation of each component is ≤5%, and the mixed solution is determined to be uniform; The detection of the uniformity of the mixed solution is carried out by high performance liquid chromatography, and the detection conditions are as follows: a C18 column, a mobile phase of methanol-0.1% phosphoric acid aqueous solution, a flow rate of 1.0 mL / min, and detection wavelengths of 280 nm and 220 nm. The sample concentrations at three positions of the top, middle and bottom of the mixed solution are detected respectively, and the relative standard deviation is calculated. If the RSD is ≤5%, the mixed solution is uniform, and the next process can be carried out. This avoids excessive content fluctuation of the finished product due to uneven mixing.

[0021] The above technical scheme can realize uniform mixing and quality control of the high-proportion collagen peptide formula, increase the stirring time by 0.5 h, compensate for the difficulty of mixing collagen peptide with low-sugar components, increase the uniformity of mixing, and avoid local component enrichment.

[0022] Compared with the prior art, the present application has the following advantages: by adding collagen peptide, the antioxidant capacity of the product can be increased, the oxidative damage after exercise can be effectively alleviated, cell aging can be delayed, traditional sucrose can be banned, malt dextrin and erythritol can be used as substitutes, it is suitable for long-term consumption by fitness people, and through the targeted pretreatment process and inert gas protection technology, the problems of easy oxidation and activity loss of core components in the traditional preparation method are solved, so that tea polyphenols and tea micro-molecules and other substances are more easily absorbed and utilized by the human body; Further, by using the supercritical CO2 extraction method, the active components of catechins can be protected. The CO2 flow rate of 20-30 L / h and the extraction time of 2-3 h balance the efficiency and purity, so as to ensure that the purity of the extract is ≥95%. After purification, caffeine is further removed, so as to avoid sleep disturbance caused by caffeine intake by fitness people; Further, by using the spray drying process, the mixed solution can form uniform droplets during spray drying, powder caking caused by uneven droplet size can be avoided, the particle size distribution of 50-150 μm ensures excellent powder flowability, which is convenient for subsequent tabletting or capsule filling, and avoids the occurrence of large particles.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1: To address the problems of existing nutritional products using a single antioxidant component, such as limited antioxidant effect, easy inactivation of core components during preparation, and difficulty in simultaneously meeting the needs of sports nutrition supplementation and long-term anti-aging, the following solution is disclosed. Please refer to [link / reference]. Figures 1-2 This invention provides a technical solution: a method for preparing an anti-aging fitness nutritional product, comprising the following steps: Step 1: Weigh the raw materials according to their weight, including tea polyphenols, tea micromolecules, collagen peptides, vitamin E, vitamin C, maltodextrin, and erythritol; Before weighing, the moisture content of tea polyphenols was 5.2%, the transmittance of tea micromolecule solution was 96%, and the moisture content of collagen peptides was 5.8%. An electronic scale was used for weighing, and the weighing deviation of each component was ≤0.2g.

[0026] Step 2: Pre-treat tea polyphenols and tea micromolecules. Place the tea polyphenols in a vacuum drying oven at 30-50℃ and dry for 2-3 hours. At the same time, filter the tea micromolecules through a microporous membrane to remove impurities. During tea micro-molecule filtration, six portions of tea micro-molecule solution were passed through a 0.22 μm microporous membrane, with a flow rate of 6 mL / min and a pressure of 0.12 MPa controlled. After filtration, a clear and purified liquid was obtained with a transmittance of 97%. Step 3: Mix the pretreated tea polyphenols, tea micromolecules with collagen peptides, vitamin E and vitamin C, add deionized water to make a mixture with a concentration of 20%-30%, and stir for 1-2 hours at a temperature of 50-60℃ and a speed of 200-300rpm. Step 4: Add maltodextrin and erythritol to the mixture, continue stirring for 30-50 minutes, and then process it using a spray drying process with an inlet air temperature of 180-200℃ and an outlet air temperature of 80-90℃. After drying, a powdered semi-finished product is obtained. After drying, a powdered semi-finished product was obtained with a moisture content of 2.8%, a particle size distribution of 80-120 μm, a bulk density of 0.4 g / cm³, and a yield of 93%. Step 5: After screening the semi-finished product through an 80-120 mesh sieve to remove clumps, use a tablet press to compress it into tablets or fill it into capsule shells to obtain anti-aging and fitness nutritional products. When the raw materials are weighed, the raw material ratio is 6-10 parts of tea polyphenol, 4-8 parts of tea micro-molecule, 3-5 parts of collagen peptide, 0.5-2 parts of vitamin E, 0.3-1.5 parts of vitamin C, 6-12 parts of malt dextrin, and 3-6 parts of erythritol; The tea polyphenol is extracted from tea liquid such as green tea or oolong tea, and the purity is greater than or equal to 95%, and the content of catechin components is not less than 70%. The extraction process adopts supercritical CO2 extraction method, the extraction pressure is controlled to be 30-40 MPa, the extraction temperature is 40-50℃, the CO2 flow is 20-30 L / h, the extraction time is 2-3 h, and the extraction needs to be purified after extraction; The supercritical CO2 extraction method is a low-temperature extraction process, which can effectively avoid the damage of high temperature to catechin, and the catechin retention rate is increased by more than 30% compared with the traditional solvent extraction method; the extraction pressure of 30-40 MPa can ensure that CO2 is in a supercritical state; The tea micro-molecule is prepared by superhigh pressure homogenization method, the molecular particle size is controlled to be 100-500 nm, and the active ingredient retention rate is greater than or equal to 90% through high performance liquid chromatography detection; the superhigh pressure homogenization technology utilizes 100-1000 MPa static or dynamic to uniformly transmit the pressure to the tea raw material system through the liquid medium, and initiates multiple physical effects to realize molecular dispersion; The shear effect caused by high pressure can break the macromolecular groups of tea extract into small molecules, and the cavitation effect can form micro-bubbles in the liquid, and the impact force generated by the bubble rupture can further refine the molecular particle size; the finally obtained tea micro-molecule has a uniform particle size distribution of 100-500 nm, can be directly absorbed through the gap of intestinal epithelial cells, and the absorption rate is increased by more than 80% compared with the non-homogenization treatment, and the active ingredient retention rate is greater than or equal to 90%; The conductivity of deionized water is less than or equal to 10 μS / cm, and inert gas protection is adopted during mixing to prevent oxidation of the raw materials; inert gas protection is adopted during mixing; In addition to nitrogen, argon can also be used for inert gas protection to increase the protection effect; the gas needs to be filtered through a 0.2 μm filter membrane before being introduced into the mixing tank to prevent impurity particles carried in the gas from polluting the mixed solution; at the same time, a one-way valve needs to be installed at the exhaust port of the mixing tank to prevent air from flowing back, and to ensure that the whole mixing process is in an inert gas atmosphere; When the mixed solution is subjected to spray drying process, the feeding speed of spray drying is 15-25 mL / min, and the atomization pressure is 0.2-0.3 MPa, so as to ensure that the powder particle size is uniform, and the particle size distribution is 50-150 μm; The atomizer of the spray dryer adopts a titanium alloy centrifugal atomizing disc, which can avoid metal ion dissolution to contaminate the product; the feed rate of 15-25 mL / min and the atomizing pressure of 0.2-0.3 MPa need to be matched and adjusted, for example, when the feed rate is increased to 25 mL / min, the atomizing pressure needs to be increased to 0.3 MPa accordingly, to ensure that the mixed solution forms uniform mist droplets, and to avoid incomplete drying due to too large mist droplets or powder scattering due to too small mist droplets.

[0027] In this embodiment, another product formula is disclosed, which is different from that of Example 1, and specifically as shown in Figure 2 The difference between this embodiment and Example 1 is that the raw materials are weighed according to the following proportions: tea polyphenol 5-10 parts, tea micro-molecule 5-8 parts, collagen peptide 4-6 parts, vitamin E content 0.5-2 parts, vitamin C content 0.3-1.5 parts, malt dextrin 3-8 parts, and erythritol 2-4 parts. The reduction of the contents of malt dextrin and erythritol can reduce the sugar content of the fitness nutrition product, and a high proportion of collagen peptide needs to ensure its activity. However, as a high-protein nutritional ingredient, the activity of collagen peptide is sensitive to temperature and pressure, so its activity needs to be ensured during the preparation process. During the mixing process, the temperature is controlled at 45-55°C, and the stirring speed is stabilized at 250-300 rpm, to avoid the breakage of the peptide bond of collagen peptide due to excessively high temperature or fluctuation of the stirring speed. To further ensure the activity of collagen peptide, the outlet air temperature needs to be controlled at 80-85°C during the spray drying stage to reduce the damage to the peptide bond caused by high temperature. The dried powder needs to be sealed and packaged, and an oxygen absorber needs to be placed in the package to prevent the oxidation of collagen peptide during storage. When mixing and stirring tea polyphenol, tea micro-molecule, collagen peptide, vitamin E, vitamin C, malt dextrin, and erythritol, the stirring time needs to be increased by 0.5 h due to the increase of collagen peptide and the reduction of the contents of malt dextrin and erythritol. After the stirring is completed, the uniformity of the mixed solution is detected by sampling, and the content deviation of tea polyphenol and collagen peptide in the mixed solution is detected by high-performance liquid chromatography, to ensure that the content deviation of each component is ≤5%, and the mixed solution is determined to be uniform. The detection of the uniformity of the mixed solution adopts high-performance liquid chromatography, and the detection conditions are as follows: a C18 chromatographic column, a mobile phase of methanol-0.1% phosphoric acid aqueous solution, a flow rate of 1.0 mL / min, and detection wavelengths of 280 nm and 220 nm. The sample concentrations at the upper, middle, and lower positions of the mixed solution are detected respectively, and the relative standard deviation is calculated. If the RSD is ≤5%, the mixed solution is uniform, and the next process can be entered. Avoiding excessive content fluctuation of the finished product due to uneven mixing.
