Description

Technical Field

[0001] The invention relates to the technical field of infant milk powder and equipment, and in particular to milk powder with a synergistic effect of a golden ratio of key nutrients and an aseptic proportioning equipment thereof. Background Art

[0002] Infant formula, as an important supplement to infant nutrition, its quality and safety are directly related to the healthy growth and development of babies. In modern parenting concepts, breast milk is recognized as the most ideal food for babies. It is rich in various nutrients, immune factors and growth factors, and plays an irreplaceable role in the establishment of the baby's immune system, digestive system development and intellectual growth. However, in some cases, such as when the mother is unable to breastfeed due to physical reasons, or when breast milk is insufficient, infant formula becomes an indispensable choice. High-quality infant formula usually contains rich protein, fat, carbohydrates, vitamins, minerals and necessary trace elements, such as calcium, iron and zinc, three important minerals. Calcium is important for bone and tooth health. It is extremely important and is involved in many physiological functions such as nerve conduction and muscle contraction. Iron is an important component of hemoglobin, participates in the oxygen transport process, and is also one of the key elements for synthesizing DNA. Zinc is important for immune system function, wound healing, and cell growth and division. DHA, ARA and other key nutrients that contribute to the development of the brain and vision are designed to simulate the nutritional composition of breast milk, which can not only meet the nutritional needs of babies at different growth stages and promote the overall growth of babies, but also ensure its safety and harmlessness. However, in the existing infant formula, there are few studies on key nutrients in the key stages of infant growth. In view of this, we propose a synergistic milk powder with a golden ratio of key nutrients and its aseptic mixing equipment. Summary of the invention

[0003] The purpose of the present invention is to provide milk powder with synergistic effects of key nutrients in a golden ratio and aseptic proportioning equipment thereof, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides a milk powder with a synergistic effect of key nutrients in a golden ratio, comprising the following components: 60-80 parts by weight of high-oil whey powder, 10-20 parts by weight of whole milk powder, 5-10 parts by weight of lactose, 2-8 parts by weight of whey protein powder, 1.5-3.5 parts by weight of choline bitartrate, 1-5 parts by weight of polyfructose, 0.3-0.7 parts by weight of taurine, 0.5-1 parts by weight of a compound functional nutrition enhancer, 0.05-0.1 parts by weight of a compound nucleotide, 0.03-0.09 parts by weight of lactoferrin, 0.4-0.8 parts by weight of a compound vitamin, and 0.2-0.7 parts by weight of a compound mineral.

[0005] The compound functional nutrition enhancer is prepared by mixing 0.1-0.5 parts by weight of calcium chloride, 0.1-0.3 parts by weight of ferrous sulfate, 0.5-1.5 parts by weight of tricalcium phosphate, 0.1-0.5 parts by weight of zinc lactate, 0.3-1.5 parts by weight of arachidonic acid, 0.8-1.5 parts by weight of docosahexaenoic acid, and 0.2-1 parts by weight of casein phosphopeptide;

[0006] The compound vitamin is prepared by mixing 0.01-0.05 weight parts of pyridoxine hydrochloride, 0.01-0.03 weight parts of phytonadione, 0.01-0.05 weight parts of cholecalciferol, 0.01-0.04 weight parts of retinyl acetate, 0.01-0.05 weight parts of D-biotin, 0.05-0.07 weight parts of nicotinamide, 0.01-0.03 weight parts of riboflavin, 0.01-0.05 weight parts of folic acid, 0.01-0.03 weight parts of cyanocobalamin and 0.1-0.4 weight parts of dl-α-tocopherol acetate;

[0007] The composite mineral is prepared by mixing 0.1-0.5 parts by weight of magnesium sulfate, 0.1-0.3 parts by weight of copper sulfate, 0.1-0.4 parts by weight of manganese sulfate, 0.01-0.05 parts by weight of potassium iodate and 0.01-0.05 parts by weight of sodium selenite;

[0008] The composite nucleotide is prepared by mixing 0.02-0.1 parts by weight of 5'-cytidylic acid disodium, 0.01-0.1 parts by weight of 5'-uridylic acid disodium, 0.09-0.3 parts by weight of 5' adenosine monophosphate, 0.01-0.1 parts by weight of 5'-inosinic acid disodium and 0.05-0.1 parts by weight of 5'-guanylic acid disodium.

[0009] Preferably, the processing method of polyfructose is as follows:

[0010] Add polyfructose to deionized water and stir with a glass rod until it is completely dissolved, then add the compound functional nutrient enhancer to the polyfructose solution, and use a mechanical stirrer to keep stirring, spray the mixed solution evenly into the spray dryer through a nozzle, set the spray drying parameters, continuously monitor the outlet air temperature during the spray drying process, collect the dried particles, finely screen the collected particles, and obtain the processed product of polyfructose through microencapsulation technology.

[0011] Polyfructose is a low-calorie, water-soluble dietary fiber that helps promote intestinal health and improve the function of the digestive system. Combining the compound functional nutritional enhancer with polyfructose through microencapsulation technology helps to improve the stability of the compound functional nutritional enhancer and protect it from the influence of the external environment, thereby enhancing the bioavailability of the nutritional components in the human body, promoting the healthy growth of babies, and indirectly greatly improving the ability of babies at different growth stages to absorb the key nutrients they need. At the same time, the golden ratio is combined with the nutrients required for each key stage of the baby's development to achieve synergistic effects, further improving the absorption and utilization of milk powder in the baby's body, which plays an important role in the growth and development of the baby.

[0012] In order to meet the special nutritional needs of infants and young children in specific groups, some additional nutrients are added to milk powder, such as three important minerals: calcium, iron and zinc. Calcium is essential for bone and tooth health, and is involved in multiple physiological functions such as nerve conduction and muscle contraction. Iron is an important component of hemoglobin, participates in the oxygen transport process, and is also one of the key elements for synthesizing DNA. Zinc is important for immune system function, wound healing, and cell growth and division. Milk powder prepared by scientifically matching milk sources and calcium, iron and zinc can not only provide basic nutrition from milk sources, but also supplement specific nutrients through fortified ingredients to achieve the effect of double supplementation, providing infants with more balanced and comprehensive nutritional support, and realizing the scientific ratio of "milk source + fortification" dual-effect supplement - calcium, iron and zinc.

[0013] Casein phosphopeptide (CPP) is a special peptide extracted from cow casein. It has the function of promoting the absorption of certain minerals (such as calcium, iron, zinc, etc.) and can form soluble complexes with minerals to help the human body better absorb these nutrients. Vitamin C (VC) is a powerful antioxidant that not only enhances the function of the immune system and helps the absorption of iron, but also reduces trivalent iron to divalent iron, making iron more easily absorbed by the small intestine. Vitamin D (VD) is essential for the absorption of calcium. It can help regulate the metabolism of calcium and phosphorus in the body, promote the absorption of calcium in the intestine, and help maintain bone health. When milk powder contains CPP, vitamin C and vitamin D at the same time, these ingredients work together to improve the absorption efficiency of minerals (especially calcium, iron, zinc), thereby forming a "golden formula" that helps ensure that infants and young children can absorb nutrients in milk powder more effectively, thereby achieving better nutritional supplementation effects.

[0014] Preferably, the mass fraction of the polyfructose solution is 10-15%.

[0015] Preferably, the feed temperature is 160-180°C, the air outlet temperature is 70-90°C, the spray rate is 10-20mL / min, and the air flow rate is 200-400L / min.

[0016] Preferably, the particle size of the fine screening is 0-30 μm.

[0017] As a preferred method, the method for preparing milk powder with synergistic effect of key nutrients in golden ratio is as follows:

[0018] Various raw materials are accurately weighed according to the formula ratio, and after ultraviolet sterilization in the sterilizer, they enter the mixing area of ​​the aseptic proportioning equipment, high-oil whey powder, whole milk powder, lactose, whey protein powder, choline bitartrate, taurine and lactoferrin are preliminarily mixed, and then compound vitamins, compound minerals and compound nucleotides are added from the feed port in sequence, and finally 4-6 weight parts of polyfructose processed products are added. After thorough dry mixing and uniform mixing, the powder is sieved at 0-50μm and enters the hopper of the packaging machine for canning. After vacuuming, inert gas is introduced and the powder is sealed and packed to obtain milk powder with a synergistic golden ratio of key nutrients.

[0019] Preferably, the inert gas comprises 20%-70% nitrogen and 30-80% carbon dioxide.

[0020] On the other hand, the present invention provides an aseptic proportioning device for milk powder with a synergistic effect of a golden ratio of key nutrients, which is used for the milk powder with a synergistic effect of a golden ratio of key nutrients as described in any one of the above items, comprising a proportioning chamber, a plurality of ultraviolet sterilization lamps are installed on the inner wall of the proportioning chamber, a support frame is fixedly installed around the proportioning chamber, a motor is fixedly installed at the top center of the proportioning chamber, and a stirring chamber is arranged in the proportioning chamber, a feeding port connected to the stirring chamber is opened at the top of the proportioning chamber, one end of the output shaft of the motor is fixedly connected to a rotating shaft, one end of the rotating shaft passes through the proportioning chamber and extends into the stirring chamber, and a lower hopper is also opened at the bottom of the proportioning chamber, characterized in that: a lifting part is fixedly provided on the side wall of the rotating shaft, the lifting part is used to lift the milk powder raw materials at the bottom of the stirring chamber upward and mix them, a stirring part is fixedly provided at the bottom of the rotating shaft, and the stirring part is used to mix the milk powder raw materials; a proportioning component is also installed on the top of the proportioning chamber.

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 10As shown, the purpose of this embodiment is to provide an aseptic proportioning device for milk powder with a synergistic effect of key nutritional golden ratios, which is used for the raw material proportioning of milk powder with a synergistic effect of key nutritional golden ratios, including a proportioning chamber 9, and a plurality of ultraviolet sterilization lamps 11 are installed on the inner wall of the proportioning chamber 9. The ultraviolet sterilization lamps 11 can be used to fully sterilize and disinfect the milk powder raw materials during the proportioning and stirring process. A support frame 10 is fixedly installed around the proportioning chamber 9, a motor 1 is fixedly installed at the top center of the proportioning chamber 9, and a stirring chamber is arranged in the proportioning chamber 9. A feeding port 2 connected to the stirring chamber is opened at the top of the proportioning chamber 9, and a rotating shaft 3 is fixedly connected to one end of the output shaft of the motor 1. One end of the rotating shaft 3 passes through the proportioning chamber 9 and extends into the stirring chamber, and a lower hopper 8 is also opened at the bottom of the proportioning chamber 9, and a lifting part is fixedly provided on the side wall of the rotating shaft 3. The lifting part is used to lift the milk powder raw materials at the bottom of the stirring chamber upward and mix them. A stirring part is fixedly provided at the bottom of the rotating shaft 3, and the stirring part is used to mix the milk powder raw materials.

[0040] The lifting part comprises a fixing rod 4 , which is fixedly mounted on the upper and lower side walls of the rotating shaft 3 , and a spiral stirring blade 5 is fixedly mounted between the two fixing rods 4 .

[0041] The stirring part includes a sloping top tray 6, a plurality of stirring blades 7 are arranged on the edge of the sloping top tray 6, and the upper surface of the sloping top tray 6 is an inclined surface, which slopes downward from the center to the surrounding edges;

[0042] The stirring blade 7 includes a vertical stirring blade 74 and a plurality of mutually parallel horizontal stirring blades 73 fixed on the vertical stirring blade 74, the horizontal stirring blade 73 extends into the area between the spiral stirring blades 5 and is respectively located below each spiral segment on the spiral stirring blade 5; a plurality of first vertical direction-changing grooves 71 and a plurality of second vertical direction-changing grooves 72 are provided on both side surfaces of the vertical stirring blade 74, the first vertical direction-changing grooves 71 and the second vertical direction-changing grooves 72 are symmetrically arranged, and each of the first vertical direction-changing grooves 71 and the second vertical direction-changing grooves 72 are inclined; a middle triangular groove 77 is provided at the center of the top surface of the horizontal stirring blade 73, and a plurality of first transverse direction-changing grooves 75 and a plurality of second transverse direction-changing grooves 76 are provided on both sides of the middle triangular groove 77, the first transverse direction-changing grooves 75 and the second transverse direction-changing grooves 76 are symmetrically arranged, and each of the first transverse direction-changing grooves 75 and the second transverse direction-changing grooves 76 are inclined.

[0043] It should be noted that a spiral descending channel 78 is installed inside each of the first vertical turning groove 71 and the second vertical turning groove 72. After the milk powder raw materials enter the first vertical turning groove 71 and the second vertical turning groove 72, they will pass through the spiral descending channel 78. In the process of passing through the spiral descending channel 78, the milk powder raw materials will produce a spiral descending process. In this process, the milk powder raw materials will continue to turn over, thereby further increasing the uniformity of the stirring of the milk powder raw materials.

[0044] A batching assembly 12 is also installed on the top of the batching chamber 9. The batching assembly 12 includes a bottom funnel 121 installed on the feed port 2. The bottom funnel 121 is hollow inside. A plurality of batching pipes 122 are installed on the bottom funnel 121. Each batching pipe 122 is communicated with the inside of the bottom funnel 121. A feed pipe 124 is installed inside each batching pipe 122. The feed pipe 124 is fixed to the inside of the batching pipe 122 by a support bar 125 arranged at the bottom of the batching pipe 122. A top funnel 123 is installed on the top of the feed pipe 124. A lower hopper 126 is arranged at the bottom of the feed pipe 124. An indicator ring 127 that can move freely up and down along the feed pipe 124 is sleeved on the feed pipe 124. A positioning block 128 is also fixed inside the batching pipe 122 to form milk powder raw materials.

[0045] It should be noted that the batching tubes 122 in the present embodiment are provided with 12, which are respectively used to add the 12 ingredients of high oil whey powder, whole milk powder, lactose, whey protein powder, choline bitartrate, polyfructose, taurine, compound functional nutrient enhancer, compound vitamins, compound minerals, compound nucleotides and lactoferrin constituting the raw materials of milk powder, and the batching tube 122 is made of transparent glass, and a scale is provided on its surface, so that the movement of the indicator ring 127 inside the batching tube 122 can be observed very intuitively, and the ingredients are added from the top funnel 123, and the ingredients will enter the feed pipe 124 and enter the feed pipe 124. The material is discharged from the lower hopper 126 at the bottom and then enters the interior of the batching tube 122. As the ingredients are continuously added, the ingredients will continue to accumulate inside the batching tube 122, and then they will contact and push the indicator ring 127 upward, causing the indicator ring 127 to move up, and stop when the indicator ring 127 contacts the positioning block 128. The position of the positioning block 128 corresponds to the specific amount of each ingredient, which can be observed very intuitively through the scale on the surface of the batching tube 122. Through the setting of the indicator ring 127 and the positioning block 128, the required amount of ingredients can be added very accurately and conveniently without the need for prior weighing.

[0046] Furthermore, a valve is installed at the connection between the batching pipe 122 and the bottom funnel 121. When the ingredients are added, the valve can be opened to allow the ingredients to enter the bottom funnel 121 and then fall into the batching cavity 9 for subsequent stirring and mixing.

[0047] The working principle of the aseptic proportioning equipment is as follows: the ingredients are added from the top funnel 123, the ingredients will enter the feed pipe 124, and will be discharged from the lower hopper 126 at the bottom of the feed pipe 124, and then enter the inside of the batching pipe 122. As the ingredients are continuously added, the ingredients will continue to accumulate inside the batching pipe 122, and then they will contact and push the indicator ring 127 upward, causing the indicator ring 127 to move up, and stop when the indicator ring 127 contacts the positioning block 128. The position of the positioning block 128 corresponds to the specific ingredient amount of each ingredient. The scale on the surface of the batching tube 122 can be observed very intuitively, and through the setting of the indicator ring 127 and the positioning block 128, the required amount of ingredients can be added very accurately and conveniently without weighing in advance. When the ingredients are added, the valve can be opened to allow the ingredients to enter the bottom funnel 121 and then fall into the batching chamber 9 for subsequent stirring and mixing. After falling into the batching chamber 9, the ultraviolet sterilization lamp 11 is turned on to sterilize the milk powder raw materials; then the motor 1 is turned on, and the rotating shaft 3 rotates along with the output of the motor 1. The shaft rotates, and a fixed rod 4 is fixedly connected to the rotating shaft 3, and a spiral stirring blade 5 is fixedly connected to the fixed rod 4. When the rotating shaft 3 rotates clockwise, the spiral stirring blade 5 also rotates clockwise through the fixed rod 4. At this time, the spiral stirring blade 5 drives the milk powder raw material at the bottom to move upward until it reaches the top, and then makes a free fall motion and returns to the inclined top tray 6. Since the structure of the inclined top tray 6 is to descend and tilt from the center to the edges around, the milk powder raw material slides to the edges around the inclined top tray 6, thereby avoiding the accumulation of the milk powder raw material. Because the inclined bottom tray 6 is fixedly connected to the rotating shaft 3, and a plurality of stirring blades 7 are arranged on the edge of the inclined top tray 6, the rotating shaft 3 will also drive the stirring blade 7 to make a circular motion with the rotating shaft 3 as the center. At this time, the stirring blade 7 on the edge of the inclined bottom tray 6 mixes and stirs the milk powder raw material. When the milk powder raw material is mixed, the rotating shaft 3 is rotated counterclockwise by the output shaft of the motor 1, and the spiral stirring blade 5 also rotates counterclockwise through the fixed rod 4 to transport the raw material downward, so that the mixed raw material can be quickly transported out from the lower hopper 8.

[0048] During the mixing process of the ingredients, the vertical stirring blades 74 and the horizontal stirring blades 73 will fully stir the milk powder raw materials and continuously contact the milk powder raw materials. During the contact process, the milk powder raw materials will continuously enter the first vertical direction-changing groove 71, the second vertical direction-changing groove 72, the first horizontal direction-changing groove 75 and the second horizontal direction-changing groove 76. The first vertical direction-changing groove 71, the second vertical direction-changing groove 72, the first horizontal direction-changing groove 75 and the second horizontal direction-changing groove 76 are all inclined grooves. After entering the vertical direction-changing groove 72, the first transverse direction-changing groove 75 and the second transverse direction-changing groove 76, the raw milk powder will move along the groove body. During the movement, the raw milk powder will continuously change direction. Therefore, this process can promote the mixing uniformity of the raw milk powder. After entering the first vertical direction-changing groove 71 and the second vertical direction-changing groove 72, the raw milk powder will pass through the spiral descending channel 78. In the process of passing through the spiral descending channel 78, the raw milk powder will produce a spiral descending process. In this process, the raw milk powder will continuously turn over, thereby further increasing the mixing uniformity of the raw milk powder. Moreover, since the first vertical direction-changing groove 71 and the second vertical direction-changing groove 72 are symmetrically arranged, and the first horizontal direction-changing groove 75 and the second horizontal direction-changing groove 76 are symmetrically arranged, the moving directions of the milk powder raw materials entering the first vertical direction-changing groove 71 and the second vertical direction-changing groove 72 are different, and the moving directions of the milk powder raw materials entering the first horizontal direction-changing groove 75 and the second horizontal direction-changing groove 76 are different, which will further increase the disorder of the milk powder raw materials during the stirring process, and further increase the stirring uniformity. At the same time, the spiral stirring blade 5 will drive the milk powder raw materials at the bottom to move upward, and will continue to fall during the upward movement, and the fallen milk powder raw materials will fall into the middle triangular groove 77 on the horizontal stirring blade 73, and then fall from the middle triangular groove 77 into the first horizontal direction-changing groove 75 and the second horizontal direction-changing groove 76 on both sides thereof, so that a coordinated effect can be formed with the spiral stirring blade 5, so as to promote the mixing of the continuously rising and falling milk powder raw materials, further aggravate the disorder and uniformity of the mixing, and thus improve the quality of the ingredients.

[0049] Furthermore, a sealing disk is provided at the junction of the lower hopper 8 and the inclined top tray 6. The diameter of the sealing disk is the same as the top diameter of the lower hopper 8, and the bottom end of the sealing disk is connected to a cylinder for driving it to move up and down. The cylinder is fixed on the inner wall of the lower hopper 8. Before the mixing process starts, it is necessary to start the cylinder to push the sealing disk down until the sealing disk and the inner wall of the lower hopper 8 are tightly fitted together to prevent the milk powder raw materials from falling. After the mixing is completed, the cylinder pushes the sealing disk up to form a material passing space between the sealing disk and the inner wall of the lower hopper 8, so that the mixed milk powder raw materials can fall into the lower hopper 8 and finally be discharged.

[0050] It should be noted that a solenoid valve is installed on the discharge hopper 8, which can accurately control the amount of discharge, thereby controlling the amount of milk powder raw materials.

[0096] Comparative Example 1: The method of Example 3 was adopted without adding the processed product of polyfructose.

[0097] Comparative Example 2: The method of Example 3 was adopted to directly add the compound functional nutrition enhancer and polyfructose into the milk powder without microencapsulation processing.

[0098] Comparative Example 3: Using the method of Example 3, 0.005 parts by weight of the compound functional nutrition enhancer and 0.5 parts by weight of polyfructose were weighed to prepare a processed product of polyfructose, and the processed product was added to the milk powder component.

[0099] The present invention adopts the processed product of polyfructose to prepare the milk powder with synergistic effect of key nutrients in golden ratio, wherein the performance index inspection items and inspection standards of the milk powder with synergistic effect of key nutrients in golden ratio are as follows:

[0100] 70 C57BL / 6 mice were selected and randomly divided into 7 groups, with 10 mice in each group. They were gavaged with 0.2 mL of control formula milk every morning for 2 weeks. Feces were collected for pH detection and analysis before and after the gavage experiment. The pH value of feces was close to the pH value in the colon. Measuring the pH value in feces can estimate the pH value in the colon. A decrease in pH in the colon is beneficial to inhibiting the growth and proliferation of saprophytes, thereby preventing / treating intestinal diseases such as enteritis and colon cancer and promoting intestinal health. Therefore, the lower the pH value of the feces, the healthier the intestine and the better the nutrient absorption capacity.

[0101] 70 SD rats of both sexes, SPF grade, were kept in the animal room at about 20℃, fed once a day, the feeding amount was 15% of the rat's body weight, and distilled water was freely available for drinking. The rats were kept for 4 weeks, and the diarrhea of ​​the observed animals was recorded from 0th to 28th day. Diarrhea rate (%) = cumulative number of SD rats with diarrhea during the test period × total number of diarrhea days / total number of experimental SD rats × number of test days.

[0102] According to the above standards, the milk powders with synergistic effects of key nutrients in golden ratio prepared in the above Examples 1-5 and Comparative Examples 1-3 were tested, and the obtained data are shown in Table 1:

[0103] Table 1 Performance data of Examples 1-5 and Comparative Examples 1-3

[0104]

[0105] The above data fully demonstrate that compared with Comparative Examples 1-3, Examples 1-5 can fully demonstrate the effect of the processed products of polyfructose on the intestinal health protection performance of milk powder with synergistic enhancement of key nutritional golden ratios.

[0106] Since the present invention uses the processed product of polyfructose to prepare the milk powder with the golden ratio of key nutrients and synergistic enhancement, the processed product of polyfructose effectively improves the performance of intestinal health protection, as follows:

[0107] It can be seen from Examples 1-3 that as the content of processed products of polyfructose in milk powder continues to increase, the intestinal health protection is significantly improved. This is because polyfructose, as a prebiotic, can be used by probiotics in the intestine to promote their proliferation, help maintain the balance of intestinal flora, reduce the number of harmful bacteria, improve intestinal motility, and prevent constipation and other problems. At the same time, polyfructose as a carrier can improve the bioavailability of the compound functional nutritional enhancer, improve stability, and make it easier to be absorbed by the intestine. Therefore, as the content of processed products of polyfructose in milk powder increases, the intestinal health protection effect is enhanced.

[0108] It can be seen from Examples 3 and 4 that with the continuous changes in the content of high-oil whey powder, whole milk powder, lactose, whey protein powder, choline bitartrate, taurine, compound vitamins, compound minerals, compound nucleotides and lactoferrin in milk powder, there is no obvious change in the protection of intestinal health. The above ingredients are all important nutrients in milk powder and play an indispensable role in physical health, but their specific protective effect on intestinal health is not as direct as polyfructose. The effects of these ingredients are more reflected in providing basic nutritional needs and supporting overall health, rather than directly targeting intestinal health. Therefore, there is no obvious change in the intestinal health protection effect.

[0109] It can be seen from Examples 4 and 5 that as the content of the compound functional nutritional enhancer and polyfructose in the processed product of polyfructose decreases, the effect of intestinal health protection decreases. This is because polyfructose is an important component for intestinal health and can promote the balance of intestinal flora. Therefore, when their content decreases, the effect of intestinal health protection decreases.

[0110] According to the above test experiments, the milk powder with synergistic effect of the key nutrients golden ratio prepared according to Example 3 has the best performance, so Example 3 is taken as the best example;

[0111] By comparing Example 3 with Comparative Examples 1-3, it can be seen that:

[0112] In comparative example 1, the processed products without adding polyfructose have a worse effect in protecting intestinal health. This is because polyfructose can enhance the positive impact on intestinal health, while the lack of polyfructose and its processed products lacks the biological activity and synergistic effect they provide, which makes the milk powder less effective in protecting intestinal health.

[0113] In Comparative Example 2, the compound functional nutritional enhancer and polyfructose are directly added to the milk powder without microencapsulation technology processing. The effect of intestinal health protection is worse. This is because the compound functional nutritional enhancer itself has poor stability. It is easy to decompose when added directly to milk powder, affecting its absorption and utilization in the intestine. In addition, the compound functional nutritional enhancer is more easily affected by external factors such as light, temperature and humidity, resulting in reduced activity. The nutrition required by the infant is not sufficient, and thus the effect of intestinal health protection is worse.

[0114] Comparative Example 3: 0.005 parts by weight of a compound functional nutritional enhancer and 0.5 parts by weight of polyfructose are weighed to prepare a processed product of polyfructose, and the processed product is added to the milk powder component. The worse the effect on intestinal health protection is, the more the added amount is, the lower the total content of the compound functional nutritional enhancer and polyfructose in the milk powder is, which is not enough to produce significant biological activity effects, nor is it enough to produce significant health benefits, and their biological activity cannot be fully exerted, so the effect on intestinal health protection becomes worse.

[0115] In summary, the prebiotic fiber polyfructose promotes intestinal health and the growth of beneficial bacteria, achieving a dual role in protecting the intestinal health of infants. It greatly improves the ability of babies at different growth stages to absorb the key nutrients they need. At the same time, it combines the nutrients required for each key stage of the baby's development in a golden ratio to achieve synergistic effects, further improving the absorption and utilization of milk powder in the baby's body, which plays an important role in the growth and development of the baby.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the present invention, and are not intended to limit the present invention.
