Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically a production process for a peanut protein nutritional powder that lowers blood lipids and strengthens the stomach. Background Technology

[0002] As living standards improve, people's dietary structure changes, and health problems such as high blood lipids and gastrointestinal discomfort are becoming increasingly prominent. High blood lipids increase the risk of cardiovascular disease and affect physical health; while poor gastrointestinal function reduces nutrient absorption efficiency and lowers quality of life. At present, there are many products on the market that target lowering blood lipids and improving stomach health, but most of them have problems such as single function, unhealthy ingredients, and complex manufacturing processes that lead to nutrient loss.

[0003] Peanuts are rich in protein, unsaturated fatty acids, and various minerals. Defatted peanut protein powder, obtained through defatting, is not only high in protein but also low in fat, making it suitable for people with high cholesterol. Whole flaxseed powder is rich in alpha-linolenic acid, which can be converted into DHA and EPA, helping to lower blood lipids. Its dietary fiber also promotes intestinal motility, improving the intestinal environment and aiding digestion. Sunflower seed oil and safflower seed oil are rich in unsaturated fatty acids, especially linoleic acid, which help lower blood lipids and maintain cardiovascular health. Scientifically combining these ingredients to develop a peanut protein nutritional powder that combines lipid-lowering and stomach-strengthening effects has significant market value and practical implications. Summary of the Invention

[0004] The purpose of this invention is to develop a peanut protein nutritional powder that integrates the effects of lowering blood lipids and strengthening the stomach, and to provide a production process for a peanut protein nutritional powder that lowers blood lipids and strengthens the stomach.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a production process for a peanut protein nutritional powder that lowers blood lipids and strengthens the stomach, comprising the following raw materials in parts by weight: 25-45 parts defatted peanut protein powder, 8-15 parts whole flaxseed powder, 5-12 parts dietary fiber, 2-6 parts sunflower seed oil, 1-4 parts safflower seed oil, 0.5-2 parts emulsifier, and 0.01-0.1 parts antioxidant.

[0006] The dietary fiber is selected from one or more of xylooligosaccharides, polydextrose, and oat fiber.

[0007] Preferably, the dietary fiber is a mixture of xylooligosaccharides, polydextrose, and oat fiber in a weight ratio of 1:1:1, and is passed through a 120-mesh sieve for later use.

[0008] The emulsifier is either soybean lecithin or sunflower lecithin, used to uniformly disperse the oil and form a stable emulsion system; the antioxidant is either vitamin E or rosemary extract, used to prevent the oxidation of unsaturated fatty acids and extend the shelf life of the product.

[0009] The specific steps in the production process of the lipid-lowering and stomach-strengthening peanut protein nutritional powder are as follows. Step 1: Raw material pretreatment: Select high-quality peanuts, screen and wash them, and use low-temperature pressing to obtain defatted peanut protein powder, ensuring that the moisture content of the defatted peanut protein powder is below 4%, the protein content is not less than 65%, and the fat content does not exceed 5%; after screening and washing flaxseed, dry it at low temperature until the moisture content is below 7%, then grind it into whole fat flaxseed powder, pass it through a 100-120 mesh sieve, and select one or more of the following dietary fiber: xylooligosaccharides, polydextrose, oat fiber, etc., and pass it through a 120 mesh sieve for later use; Step 2: Preliminary mixing: According to the formula ratio, put defatted peanut protein powder, whole flaxseed powder, and dietary fiber into a horizontal mixer and dry mix at a speed of 12-18 rpm for 8-12 minutes to make the powdered raw materials initially mixed evenly. Step 3: Oil Emulsification and Addition: After thoroughly mixing sunflower seed oil, safflower seed oil, emulsifier, and antioxidant, slowly add the mixture to the above materials. At the same time, turn on the high-speed emulsifier, control the emulsification temperature at 40-45℃, the emulsification speed at 5000-8000 rpm, and the emulsification time at 25-35 minutes, so that the oil is evenly dispersed in the materials to form a stable emulsion system with an emulsion particle size ≤10μm. Step 4: Granulation: The emulsified material is fed to an extrusion granulator for granulation. The granulation temperature is controlled at 50-60℃ to form particles with a relatively uniform particle size, thereby improving the product's reconstitution and taste. Step 5: Drying and secondary mixing: The granulated material is sent to a fluidized bed dryer for drying. The inlet air temperature is controlled at 150-170℃ and the outlet air temperature is controlled at 70-80℃ to reduce the moisture content of the material to below 3%. The dried material is then put back into a three-dimensional mixer and mixed at a speed of 18-22 rpm for 12-15 minutes to further ensure the uniformity of the product. Step Six: Packaging: Pack according to quantitative requirements, using nitrogen-filled packaging or vacuum packaging to extend the product's shelf life and maintain stable product quality.

[0028] Packaging: All the following examples and comparative examples were ultimately packaged using nitrogen-filled aluminum foil composite film. Example 1

[0029] Please see Figures 1 to 7 In this embodiment of the invention, a production process for a peanut protein nutritional powder that lowers blood lipids and strengthens the stomach comprises the following raw materials in parts by weight: 25 portions of defatted peanut protein powder; 15 parts whole fat flaxseed powder; 12 servings of dietary fiber; 6 parts sunflower seed oil; 4 parts safflower seed oil; 2 parts soybean lecithin; Vitamin E 0.1 part; The dietary fiber is a compound of xylooligosaccharides, polydextrose, and oat fiber in a weight ratio of 1:1:1.

[0030] The specific steps in the production process of the lipid-lowering and stomach-strengthening peanut protein nutritional powder are as follows: Step 1: Raw Material Pretreatment: Select high-quality peanuts, screen and wash them, then use a low-temperature pressing method to obtain defatted peanut protein powder. Testing shows its moisture content is 3.5%, protein content is 68%, and fat content is 4.2%. Flaxseed is screened and washed, then dried at low temperature to a moisture content of 6.2%, followed by grinding with a pulverizer and passing through a 110-mesh sieve to obtain whole flaxseed powder. Xylooligosaccharides, polydextrose, and oat fiber are compounded in a 1:1:1 weight ratio, mixed, and then passed through a 120-mesh sieve for later use.

[0031] Step 2, Preliminary Mixing: Accurately weigh the defatted peanut protein powder, whole flaxseed powder, and dietary fiber according to the above formula ratio, and put them all into the horizontal mixer. Close the feed inlet, start the mixer, and dry mix at 18 rpm for 12 minutes. After stopping the machine, check that the powdered raw materials have been initially mixed evenly.

[0032] Step 3: Oil Emulsification and Addition: Place sunflower seed oil, safflower seed oil, soybean lecithin, and vitamin E in a container and mix thoroughly. While the horizontal mixer is running at low speed (12 rpm), use a peristaltic pump to slowly and evenly spray the mixed oils into the mixture. After all the oils have been added, turn off the horizontal mixer and transfer the material to a high-speed emulsifier. Turn on the high-speed emulsifier, control the emulsification temperature at 45℃, the emulsification speed at 8000 rpm, and the emulsification time at 35 minutes. After completion, observe that the oils are evenly dispersed in the material, forming a stable emulsion system.

[0033] Step 4: Granulation: The emulsified material is evenly conveyed to the feed hopper of the extrusion granulator via a screw conveyor. The temperature in the granulation zone is controlled at 60℃. After being extruded by the extrusion rollers, the material is discharged through the die holes, forming strips. These strips are then lightly crushed and granulated by the crushing rollers, and finally collected as uniform particles of 20-40 mesh through a vibrating screen.

[0034] Step 5: Drying and Secondary Mixing: The granulated material is fed into a fluidized bed dryer. The inlet air temperature is controlled at 150℃, and drying is continued for 20 minutes; throughout the drying process, the outlet air temperature is kept stable at 80℃. After drying, a sample is taken for testing, and the moisture content of the material is 2.7%. All the dried material is then placed into a three-dimensional mixer and mixed at a speed of 22 rpm for 15 minutes to further ensure the uniformity of the product.

[0035] Step Six: Packaging: The thoroughly mixed final product is fed into a fully automatic packaging machine in 20-gram portions per bag. Nitrogen-filled packaging is used, employing aluminum foil composite film as the packaging material for sealed packaging to extend shelf life and maintain stable product quality.

[0036] In this embodiment, a scientifically formulated blend of defatted peanut protein powder, whole flaxseed powder, dietary fiber, sunflower seed oil, and safflower seed oil works synergistically to effectively lower blood cholesterol and triglyceride levels, thus reducing blood lipids. Simultaneously, dietary fiber and other components promote intestinal peristalsis, improve gastrointestinal function, and enhance stomach health. The product is rich in high-quality plant protein, unsaturated fatty acids, dietary fiber, and various vitamins and minerals, providing balanced nutrition to meet daily nutritional needs. All raw materials are natural, free of chemical additives and pharmaceutical ingredients, making it safe and reliable for long-term consumption with no significant side effects. The resulting peanut protein powder can be directly prepared and consumed or added to other foods, catering to the needs of diverse individuals.

[0038] In this embodiment: the emulsified material is poured into the feed hopper 3, and the material falls and comes into contact with the two extrusion rollers. The two extrusion rollers rotate in opposite directions to extrude the material. The extruded material falls into the machine body 1 through the discharge port 6. The crushing roller 7 rotates to crush the material, so that the material forms granules.

[0039] Please refer to this carefully. Figures 2 to 6The mounting mechanism 8 includes a movable groove 801 and an extrusion cylinder 5. The movable groove 801 is symmetrically located at the top of the machine body 1. A movable frame 802 is slidably connected to the inner wall of the movable groove 801.

A fixed roller 804 is fixedly connected to the outer wall of the rotating shaft 803. A limit plate 805 is fixedly connected to one side of the outer wall of the fixed roller 804. The extrusion roller is composed of the fixed roller 804 and the extrusion cylinder 5. A groove 806 is provided on the inner wall of the extrusion cylinder 5. A protrusion 807 extending from the fixed roller 804 is slidably connected inside the fixed roller 804. A first spring 808 is connected between the protrusion 807 and the fixed roller 804. A displacement groove 809 is provided on one side of the outer wall of the mounting frame 2. A connecting frame 810 is fixedly connected to the outer wall of the mounting frame 2 on one side of the displacement groove 809. A rotating column 811 is rotatably connected to the outer wall of the connecting frame 810. A second threaded rod 812 is fixedly connected to one end of the rotating column 811. An L-shaped plate 813 is slidably connected to the inner wall of the displacement groove 809. The second threaded rod 812 extends into the interior of the L-shaped plate 813. A pusher 814 is slidably connected to one end of the rotating shaft 803 inside the movable frame 802. A displacement frame 815 extending out of the rotating shaft 803 is slidably connected to the interior of the rotating shaft 803. A second spring 821 is connected between the displacement frame 815 and the rotating shaft 803. A first spur gear 816 is rotatably connected to the outer wall of the displacement frame 815 inside the rotating shaft 803. A gear 817 is slidably connected to the outer wall of the first spur gear 816 inside the L-shaped plate 813. A positioning frame 818 is fixedly connected to the outer wall of the gear 817.

[0040] In this embodiment: Rotating the rotating block 820 causes the first threaded rod 819 to rotate, and the rotation of the first threaded rod 819 causes the movable frame 802 to move. The two movable frames 802 move in opposite directions in the movable groove 801. The movement of the movable frame 802 causes the extrusion roller to move, so that the extrusion roller moves out of the mounting frame 2. When the L-shaped plate 813 is displaced, the rotating column 811 is rotated, and the rotation of the rotating column 811 drives the second threaded rod 812 to rotate. The rotation of the second threaded rod 812 drives the L-shaped plate 813 to move, and the L-shaped plate 813 slides in the displacement groove 809. The extrusion cylinder 5 is fitted onto the outer wall of the fixed roller 804 until it contacts the limiting plate 805. The protrusion 807 is engaged into the groove 806 by the elastic force of the first spring 808, positioning the extrusion cylinder 5 on the outer wall of the fixed roller 804. During the process of the L-shaped plate 813 moving towards the movable frame 802 and contacting the movable frame 802, the L-shaped plate 813 contacts the push frame 814, pushing the push frame 814 to move. The displacement of the push frame 814 pushes the displacement frame 815 to move, causing compression on the second spring 821. The displacement of the displacement frame 815 drives the first spur gear 816 to rotate. The rotation of the first spur gear 816 drives the rack 817 to move. The displacement of the rack 817 drives the positioning frame 818 to move. The positioning frame 818 moves and contacts the protrusion 807, preventing the protrusion 807 from moving into the fixed roller 804 and moving out of the groove 806, thereby fixing the extrusion cylinder 5 on the outer wall of the fixed roller 804. When disassembling the extrusion cylinder 5, the movable L-shaped plate 813 separates from the movable frame 802, and the displacement frame 815 is reset by the elastic force of the second spring 821. The first spur gear 816 drives the rack 817 and the positioning frame 818 to reset, and the positioning frame 818 separates from the protrusion 807. Then, the movable frame 802 is moved out of the mounting frame 2. At this time, the extrusion cylinder 5 can be moved out of the fixed roller 804, and the new extrusion cylinder 5 is connected to the outer wall of the fixed roller 804. The movable frame 802 enters the interior of the mounting frame 2 and is located at one end of the movable groove 801. Then, the L-shaped plate 813 is moved to contact the movable frame 802, and the outer wall of the L-shaped plate 813 contacts the adjacent two sides of the movable frame 802, thereby fixing the movable frame 802 in the movable groove 801. At the same time, the L-shaped plate 813 pushes the pusher frame 814 to move. At this time, the positioning frame 818 contacts the protrusion 807, thereby fixing the extrusion cylinder 5 to the outer wall of the fixed roller 804. This makes it easy to replace the extrusion roller by replacing different extrusion cylinders 5, and the gap between the two extrusion rollers can be adjusted by replacing extrusion cylinders 5 of different diameters, thereby adapting to different materials.

[0042] In this embodiment: the motor 901 drives the mounting shaft 902 to rotate, the mounting shaft 902 drives the second spur gear 903 to rotate, and the rotation of the second spur gear 903 drives the other mounting shaft 902 to rotate through another second spur gear 903, so that the two mounting shafts 902 rotate in opposite directions; During the process of L-shaped plate 813 displacing and contacting movable frame 802, displacement frame 815 drives rack 817 to displace via first spur gear 816. The displacement of rack 817 drives square plate 905 to displace, and square plate 905 drives third spur gear 906 to rotate. The rotation of third spur gear 906 drives fixed rod 907 to rotate. Fixed rod 907 rotates and engages in fixed groove 904, so that rotating shaft 803 and mounting shaft 902 are connected. Thus, when mounting shaft 902 rotates, it drives rotating shaft 803 to rotate. The rotation of second spur gear 903 drives fixed roller 804 and extrusion cylinder 5 to rotate synchronously. The two extrusion cylinders 5 rotate to extrude material. When extrusion roller is replaced, L-shaped plate 813 separates from movable frame 802. At the same time as rack 817 resets, fixed rod 907 rotates and resets, and moves out of fixed groove 904, so that rotating shaft 803 and mounting shaft 902 automatically separate. When the movable frame 802 moves out of the mounting frame 2, the locking block 909 engages with the toothed ring 908 under the elastic force of the third spring 910, thereby fixing the toothed ring 908 and automatically fixing the angle of the rotating shaft 803. When the movable frame 802 moves into the mounting frame 2 and contacts one end of the movable groove 801, the extrusion frame 911 contacts one end of the movable groove 801. The extrusion frame 911 is displaced under force, and the displacement of the extrusion frame 911 drives the extrusion rod 912 to move. The displacement of the extrusion rod 912 pushes the locking block 909 to move. The displacement of the locking block 909 separates from the toothed ring 908, thereby allowing the rotating shaft 803 to rotate, which facilitates the rotation of the extrusion roller.

[0043] Please refer to this carefully. Figures 2 to 6 The inner wall of the movable groove 801 fits against the outer wall of the movable frame 802. The outer wall of the movable frame 802 is provided with a first threaded hole, and the outer wall of the first threaded rod 819 is symmetrically provided with threads that match the first threaded hole.

[0044] In this embodiment: Rotating the rotating block 820 causes the first threaded rod 819 to rotate, and the rotation of the first threaded rod 819 causes the movable frame 802 to move. The two movable frames 802 move in opposite directions within the movable groove 801.

[0045] Please refer to this carefully. Figures 2 to 6 The outer wall of the L-shaped plate 813 fits into the inner wall of the displacement groove 809. The outer wall of the L-shaped plate 813 is provided with a second threaded hole, and the second threaded rod 812 matches the second threaded hole.

[0046] In this embodiment: rotating the rotating column 811 causes the second threaded rod 812 to rotate, and the rotation of the second threaded rod 812 causes the L-shaped plate 813 to move, and the L-shaped plate 813 slides in the displacement groove 809.

[0047] Please refer to this carefully. Figures 2 to 6 The protrusion 807 extends out of the fixed roller 804 and is provided with a semi-circular surface. The outer wall of one end of the protrusion 807 is in contact with the inner wall of the groove 806. The outer wall of the fixed roller 804 is in contact with the inner wall of the extrusion cylinder 5. The outer walls of the displacement frame 815 and the toothed rod 817 are both provided with a first tooth groove, which meshes with the first spur gear 816.

[0048] In this embodiment: the extrusion cylinder 5 is sleeved onto the outer wall of the fixed roller 804 until the extrusion cylinder 5 contacts the limiting plate 805. The protrusion 807 is engaged into the groove 806 by the elastic force of the first spring 808, positioning the extrusion cylinder 5 on the outer wall of the fixed roller 804. During the process of the L-shaped plate 813 moving towards the movable frame 802 and contacting the movable frame 802, the L-shaped plate 813 contacts the push frame 814, pushing the push frame 814 to move. The displacement of the push frame 814 pushes the displacement frame 815 to move, causing compression on the second spring 821. The displacement of the displacement frame 815 drives the first spur gear 816 to rotate. The rotation of the first spur gear 816 drives the rack 817 to move. The displacement of the rack 817 drives the positioning frame 818 to move. The positioning frame 818 moves and contacts the protrusion 807, preventing the protrusion 807 from moving into the fixed roller 804 and moving out of the groove 806, thereby fixing the extrusion cylinder 5 on the outer wall of the fixed roller 804.

[0049] Please refer to this carefully. Figures 7 to 9 The inner wall of the fixing groove 904 fits against the outer wall of the fixing rod 907, and the outer wall of the square plate 905 is provided with a second tooth groove, which meshes with the third spur gear 906.

[0050] In this embodiment: the displacement of the rack 817 causes the square plate 905 to move, the displacement of the square plate 905 causes the third spur gear 906 to rotate, the rotation of the third spur gear 906 causes the fixed rod 907 to rotate, and the fixed rod 907 rotates and engages into the fixed groove 904, so that the rotating shaft 803 and the mounting shaft 902 are connected. Thus, when the mounting shaft 902 rotates, the rotation of the mounting shaft 902 causes the rotating shaft 803 to rotate.

[0051] Please refer to this carefully. Figures 7 to 9 The top of the locking block 909 engages with the outer wall of the toothed ring 908. A slope is provided on one side of the locking block 909, and the pressing rod 912 contacts the slope.

[0052] In this embodiment: the locking block 909 is engaged with the toothed ring 908 by the elastic force of the third spring 910, thereby fixing the toothed ring 908 and automatically fixing the angle of the rotating shaft 803. When the movable frame 802 moves into the mounting frame 2 and contacts one end of the movable groove 801, the pressing frame 911 contacts one end of the movable groove 801. The pressing frame 911 is displaced by force. The displacement of the pressing frame 911 drives the pressing rod 912 to move. The displacement of the pressing rod 912 pushes the locking block 909 to move, and the locking block 909 separates from the toothed ring 908. Example 2

[0053] A production process for a peanut protein nutritional powder that lowers blood lipids and improves stomach health, comprising the following raw materials in parts by weight: 45 portions of defatted peanut protein powder; 8 parts whole fat flaxseed powder; 5 servings of dietary fiber; 2 parts sunflower seed oil; 1 part safflower seed oil; 0.5 parts soybean lecithin; Vitamin E 0.01 part; The dietary fiber is a compound of xylooligosaccharides, polydextrose, and oat fiber in a weight ratio of 1:1:1.

[0054] The specific steps in the production process of the lipid-lowering and stomach-strengthening peanut protein nutritional powder are as follows: Step 1: Raw Material Pretreatment: Select high-quality peanuts, screen and wash them, then use a low-temperature pressing method to obtain defatted peanut protein powder. Testing shows its moisture content is 3.8%, protein content is 70%, and fat content is 4.5%. Flaxseed is screened and washed, then dried at low temperature to a moisture content of 6.5%, followed by grinding with a pulverizer and passing through a 100-mesh sieve to obtain whole flaxseed powder. Xylooligosaccharides, polydextrose, and oat fiber are compounded in a 1:1:1 weight ratio, mixed, and then passed through a 120-mesh sieve for later use.

[0055] Step 2, Preliminary Mixing: Accurately weigh the defatted peanut protein powder, whole flaxseed powder, and dietary fiber according to the above formula ratio, and put them all into the horizontal mixer. Close the feed inlet, start the mixer, and dry mix at 12 rpm for 8 minutes. After stopping the machine, check that the powdered raw materials have been initially mixed evenly.

[0056] Step 3: Oil Emulsification and Addition: Place sunflower seed oil, safflower seed oil, soybean lecithin, and vitamin E in a container and mix thoroughly. While maintaining a low speed (10 rpm) in a horizontal mixer, use a peristaltic pump to slowly and evenly spray the mixed oils into the mixture. After all the oils have been added, turn off the horizontal mixer and transfer the material to a high-speed emulsifier. Turn on the high-speed emulsifier, control the emulsification temperature at 40℃, the emulsification speed at 5000 rpm, and the emulsification time at 25 minutes. After completion, observe that the oils are evenly dispersed in the material, forming a stable emulsion system.

[0057] Step 4, Granulation: The emulsified material is evenly conveyed to the feed hopper of the extrusion granulator via a screw conveyor. The temperature in the granulation zone is controlled at 50℃. After being extruded by the extrusion rollers, the material is discharged through the die holes, forming strips. These strips are then lightly crushed and granulated by the crushing rollers, and finally collected as uniform particles of 20-40 mesh through a vibrating screen.

[0058] Step 5: Drying and Secondary Mixing: The granulated material is fed into a fluidized bed dryer. The inlet air temperature is controlled at 155℃, and drying is continued for 15 minutes; throughout the drying process, the outlet air temperature is kept stable at 70℃. After drying, a sample is taken for testing, and the moisture content of the material is 2.9%. All the dried material is then placed into a three-dimensional mixer and mixed at a speed of 18 rpm for 12 minutes to further ensure the uniformity of the product.

[0059] Step Six: Packaging: The thoroughly mixed final product is fed into a fully automatic packaging machine in 20-gram portions per bag. Nitrogen-filled packaging is used, employing aluminum foil composite film as the packaging material for sealed packaging to extend shelf life and maintain stable product quality.

[0060] The preparation apparatus is the same as in Example 1, and will not be described again here. Example 3

[0061] A production process for a peanut protein nutritional powder that lowers blood lipids and improves stomach health, comprising the following raw materials in parts by weight: 35 portions of defatted peanut protein powder; 12 parts whole fat flaxseed powder; 8 servings of dietary fiber; 4 parts sunflower seed oil; 3 parts safflower seed oil; 1.2 parts sunflower lecithin; 0.05 parts of rosemary extract; The dietary fiber is a compound of xylooligosaccharides, polydextrose, and oat fiber in a weight ratio of 1:1:1.

[0062] The specific steps in the production process of the lipid-lowering and stomach-strengthening peanut protein nutritional powder are as follows: Step 1: Raw Material Pretreatment: Select high-quality peanuts, screen and wash them, then use a low-temperature pressing method to obtain defatted peanut protein powder. Testing shows its moisture content is 3.2%, protein content is 69%, and fat content is 4.0%. Flaxseed is screened and washed, then dried at low temperature to a moisture content of 5.8%, followed by grinding with a pulverizer and passing through a 120-mesh sieve to obtain whole flaxseed powder. Xylooligosaccharides, polydextrose, and oat fiber are compounded in a 1:1:1 weight ratio, mixed, and then passed through a 120-mesh sieve for later use.

[0063] Step 2, Preliminary Mixing: Accurately weigh the defatted peanut protein powder, whole flaxseed powder, and dietary fiber according to the above formula ratio, and put them all into the horizontal mixer. Close the feed inlet, start the mixer, and dry mix at 15 rpm for 10 minutes. After stopping the machine, check that the powdered raw materials have been initially mixed evenly.

[0064] Step 3: Oil Emulsification and Addition: Place sunflower seed oil, safflower seed oil, sunflower lecithin, and rosemary extract in a container and mix thoroughly. While maintaining a low speed (12 rpm) in a horizontal mixer, use a peristaltic pump to slowly and evenly spray the mixed oils into the mixture. After all the oils have been added, turn off the horizontal mixer and transfer the material to a high-speed emulsifier. Turn on the high-speed emulsifier, control the emulsification temperature at 42℃, the emulsification speed at 6500 rpm, and the emulsification time at 30 minutes. After completion, observe that the oils are evenly dispersed in the material, forming a stable emulsion system.

[0065] Step 4: Granulation: The emulsified material is evenly conveyed to the feed hopper of the extrusion granulator via a screw conveyor. The temperature in the granulation zone is controlled at 55℃. After being extruded by the extrusion rollers, the material is discharged through the die holes, forming strips. These strips are then lightly crushed and granulated by the crushing rollers, and finally collected as uniform particles of 20-40 mesh through a vibrating screen.

[0066] Step 5: Drying and Secondary Mixing: The granulated material is fed into a fluidized bed dryer. The inlet air temperature is controlled at 160℃, and drying is continued for 14 minutes; throughout the drying process, the outlet air temperature is kept stable at 75℃. After drying, a sample is taken for testing, and the moisture content of the material is 2.6%. All the dried material is then placed into a three-dimensional mixer and mixed at a speed of 20 rpm for 13 minutes to further ensure the uniformity of the product.

[0067] Step Six: Packaging: The thoroughly mixed final product is fed into a fully automatic packaging machine in 20-gram portions per bag. Nitrogen-filled packaging is used, employing aluminum foil composite film as the packaging material for sealed packaging to extend shelf life and maintain stable product quality.

[0068] The preparation apparatus is the same as in Example 1, and will not be described again here.

[0069] Comparative Example 1 1. Formulation: Except for the absence of emulsifier (soy lecithin) and antioxidant (vitamin E), the other raw materials and their amounts are the same as in Example 2.

[0070] 2. Production process: The production process is basically the same as that in Example 2, except for step three (oil emulsification and addition): In this comparative example, sunflower seed oil and safflower seed oil are mixed evenly and then slowly added to the mixture. Soy lecithin and vitamin E are not added. The other emulsification operation parameters remain unchanged.

[0071] Comparative Example 2 1. Formulation: Except for the absence of emulsifier (soy lecithin) and antioxidant (vitamin E), the other raw materials and their amounts are the same as in Example 2.

[0072] 2. Production Process: The production process is basically the same as in Example 2, except that step four, granulation, is completely omitted. After emulsification in step three, the emulsified material is directly subjected to drying and secondary mixing in step five, ultimately yielding a powdered product instead of a granular product.

[0073] Product Testing and Performance Analysis To verify the overall performance of the product of the present invention, the products obtained in the above three embodiments and two comparative examples were subjected to the following tests and analyses.

[0074] I. Testing Methods 1. Reconstitution Test: The reconstitution test method was performed according to the Chinese industry standard SB / T 10412-2007 "Sports Nutrition Foods and Energy Foods," with slight modifications. Accurately weigh 10.0g of the sample (accurate to 0.01g) into a clean 250mL beaker, and add 50mL of purified water at 50±1℃. Immediately place the beaker on a magnetic stirrer and stir at a fixed speed of 300±10rpm for 60±1 seconds. After stopping stirring, let it stand for 5 minutes. Then, carefully remove the floating matter and most of the supernatant from the surface using a dropper. Transfer the remaining precipitate to pre-weighed filter paper and filter it. Dry the precipitate in a 105℃ oven until constant weight, and weigh the precipitate. The less precipitate, the better the reconstitution.

[0075] 2. Flowability Measurement (Angle of Repose): The fixed funnel method is used. The funnel is vertically fixed above a horizontally placed graph paper, with the bottom opening 10 cm above the paper. The sample is allowed to flow freely from the funnel, forming a cone-shaped accumulation on the graph paper. The angle of repose of the cone is measured directly using a protractor, or by measuring the height (H) and base radius (R) of the cone, and calculated using the formula θ = arctan(H / R). Each sample is measured in triplicate, and the average value is taken. The smaller the angle of repose, the better the flowability.

[0076] 3. Peroxide value (POV) determination: Strictly follow the first titration method in GB 5009.227-2016 "National Food Safety Standard - Determination of Peroxide Value in Food". The unit is expressed as grams of active oxygen per 100 grams of sample (g / 100g).

[0077] 4. Accelerated Oxidation Test (Shelf Life Prediction): Following the principles of the accelerated oxidation test method in the General Rules of the Chinese Pharmacopoeia, each sample was sealed in a small, permeable packaging bag (simulating ordinary packaging) and placed in a constant temperature and humidity chamber at (60±1)℃ and 75±5% relative humidity for accelerated oxidation testing. Samples were taken on days 0, 7, 14, 21, and 28 to determine their peroxide value. According to relevant standards such as the National Food Safety Standard for Pastries and Bread (GB 7099-2015), a POV exceeding 0.25g / 100g is generally considered a sign of rancidity and spoilage of the oil.

[0078] 5. In vitro cholesterol adsorption rate determination: Accurately weigh 1.000 g of sample into a 50 mL Erlenmeyer flask, add 20 mL of simulated gastric juice (containing pepsin, pH=2.0) and an appropriate amount of cholesterol standard, and shake at 100 rpm for 1 hour in a 37℃ constant temperature water bath shaker. Then, slowly adjust the pH to 7.0 with 0.1 mol / L NaHCO3 solution, add 20 mL of simulated intestinal juice (containing pancreatic enzymes and bile salts), and continue shaking at 37℃ for 2 hours. After the reaction is complete, immediately place the flask in an ice-water bath to terminate the reaction, centrifuge at 4℃ and 8000 rpm for 15 minutes, collect the supernatant, and determine the content of unadsorbed cholesterol using the ferric ammonium sulfate method or high performance liquid chromatography. Cholesterol adsorption rate (%) = (1 - cholesterol content of supernatant / initial cholesterol content) × 100%.

[0079] 6. Water Holding Capacity Determination: Accurately weigh 1.000 g of sample (W1, accurate to 0.001 g) into a 50 mL centrifuge tube, add 20.0 mL of distilled water, and vortex to mix for 1 minute. Then, let it stand at room temperature (25℃) for 24 hours. Next, centrifuge at 4℃ and 4000 rpm for 20 minutes. Carefully discard the supernatant, invert the centrifuge tube to drain for 10 minutes, and weigh the precipitate (W2). Water Holding Capacity (WHC) is expressed as the number of grams of water held per gram of dry sample, calculated using the formula: WHC(g / g) = (W2 - W1) / W1.

[0080] The results of the above tests are shown in the table below. All data are averages of three parallel experiments.

[0081]

[0082] The technical solution of this invention effectively solves the industry problems commonly found in high-fat, high-fiber nutritional powders, such as poor reconstitution properties, easy oxidation, and unpleasant taste, by introducing emulsifiers and antioxidants and combining them with a refined granulation process. Practical examples demonstrate that this solution successfully reduces reconstitution sediment to below 0.6g, controls the angle of repose to within 41°, and remains stable in accelerated oxidation tests (POV ≤ 0.21 g / 100g), significantly outperforming comparative examples lacking any of these technical elements.

[0083] In summary, this invention successfully developed a peanut protein nutritional powder that integrates lipid-lowering and stomach-strengthening functions. Its advantage lies in the synergistic innovation of components and processes, ensuring core physiological functions (cholesterol adsorption rate > 35%, water retention > 4.5 g / g) while comprehensively improving the product's reconstitution properties, stability, and consumption experience, thus possessing outstanding market competitiveness and application prospects.

[0084] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
