[0003] However, when increasing the nutrients in the nutrient solution, the following technical problems often occur: the increase of minerals in the nutrients will cause the physical and chemical stability of the nutrient solution to decrease, which can easily lead to precipitation and fat layer in the nutrient solution, resulting in poor compliance, taste and appearance of the nutrient solution, and affecting the absorption and utilization of the nutrients in the nutrient solution.

Thus, after the mineral salts are mixed and diluted by maltodextrin, the subsequent local mineral concentration is avoided to be too high, causing protein denaturation. Afterwards, the mixed material and the stirred oil are formulated to obtain a formulated nutrient solution. Thus, the material and the oil can be formulated to obtain a formulated nutrient solution. Finally, the formulated nutrient solution is homogenized and sterilized to obtain a nutrient solution. Thus, the formulated nutrient solution can be homogenized and sterilized, and the bacteria in the nutrient solution can be reduced by the sterilization treatment. The fluidity of the nutrient solution can be improved by the homogenization treatment, and the stability of the nutrient solution can be increased, so that the nutrients in the nutrient solution are more evenly distributed. Therefore, the nutrient solution prepared by the nutrient solution preparation method of some embodiments of the present disclosure can still maintain the physical and chemical stability of the nutrient solution on the basis of adding minerals, thereby improving the compliance, taste and appearance of the nutrient solution, and maintaining the absorption and utilization of the nutrients in the nutrient solution.

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] refer to Figure 1 , shows a process 100 of some embodiments of the method for preparing a nutrient solution according to the present disclosure. The method for preparing a nutrient solution comprises the following steps:

[0027] Step 101, obtaining materials and stirred oil.

[0028] In some embodiments, the execution entity of the nutrient solution preparation method (for example, nutrient solution preparation equipment, which may include: process robots, hot oil tanks, mixers, mixing tanks, filters and other equipment) can obtain materials and stirred oil. The above-mentioned materials can be various materials used to prepare nutrient solutions. Among them, the above-mentioned materials may include mineral salts and maltodextrin. Here, there is no limitation on the specific material types and formula amounts included in the materials. Users can adjust according to specific nutrient solution parameters. In practice, the above-mentioned execution entity can obtain materials from the material temporary storage area.

[0029] In some optional implementations of some embodiments, the execution subject may obtain the material and the stirred oil by performing the following steps to obtain the mixed material:

[0030] The first step is to quantitatively inject at least one oil and an emulsifier into the hot oil tank through a pipeline. Among them, the at least one oil includes medium-chain triglycerides and vegetable oils, and the vegetable oils include low-erucic acid rapeseed oil and safflower oil. The emulsifier can be citric acid fatty acid glyceride. In practice, the above-mentioned execution entity can quantitatively add the oil required for the formula from the medium-chain triglyceride oil tank and the vegetable oil tank to the hot oil tank through a pipeline, and then add citric acid fatty acid glyceride to the hot oil tank. Medium-chain triglycerides are not easy to trigger appetite, and their energy density is lower than that of long-chain triglycerides. They are less deposited in adipose tissue and can be quickly digested and oxidized. A diet that replaces part of the long-chain triglycerides with medium-chain triglycerides is not easy to cause weight gain in healthy men. And medium-chain triglycerides can also be used to treat patients with fat malabsorption. In the field of sports nutrition, medium-chain triglycerides are used as an energy substance. The synergistic supply of medium-chain triglycerides and carbohydrates can prolong the energy release time and effectively maintain the energy needs of athletes during long-term exercise. The vegetable oil in the above-mentioned vegetable oil tank can include low-erucic acid rapeseed oil and safflower oil. Rapeseed oil with low erucic acid is beneficial to bile function, and the digestion and absorption rate of rapeseed oil by the human body is relatively high. Compared with other oils, the composition of rapeseed oil with low erucic acid is very low in saturated fatty acids, high in oleic acid, and intermediate in linoleic acid and linolenic acid. Eating rapeseed oil can reduce blood cholesterol levels, prevent and treat cardiovascular diseases, etc. Safflower seed oil is rich in vitamin E and sterols, has high nutritional value, and has certain effects on lowering blood pressure, anti-aging, anti-infertility and lowering blood cholesterol. The above-mentioned emulsifier can be a class of substances that form a stable emulsion of a mixed liquid of two or more immiscible components. For example, the above-mentioned emulsifier can be citric acid fatty acid glyceride. By adding the above-mentioned emulsifier, an oil-in-water emulsion can be formed, so that protein and fat are better combined to form a homogeneous emulsion, and fat and protein are prevented from separating to form a fat layer.

[0031] The second step is to heat and stir the injected at least one oil and emulsifier through the hot oil tank to obtain the stirred oil. In practice, the execution subject can heat and stir the injected at least one oil to obtain the stirred oil. The heating temperature can be greater than 80°C.

[0032] Step 102, mixing the mineral salt and maltodextrin in the material to obtain a mixed material.

[0033] In some embodiments, the execution entity may mix the mineral salt and maltodextrin in the material to obtain a mixed material.

[0034] In some optional implementations of some embodiments, the above-mentioned materials may also include compound food additives. For example, considering that there are many types of vitamins in the formula of the nutrient solution and the formula amount is low. In order to simplify the procurement of raw materials and facilitate production, vitamins can be added in the form of compound food additives. The above-mentioned compound food additives may include vitamin compound food additives, trace element compound food additives, compound food additives including chromium chloride, maltodextrin and nicotinamide, and compound food additives including sodium molybdate, maltodextrin and nicotinamide. The above-mentioned vitamin compound food additives may be compound food additives composed of a variety of vitamin food additives. The above-mentioned trace element compound food additives may be compound food additives composed of a variety of trace element food additives.

[0035] In some optional implementations of some embodiments, the execution subject may mix the mineral salts and maltodextrin in the above-mentioned materials to obtain a mixed material and a mixed material by performing the following steps: the mineral salts, maltodextrin and compound food additives in the above-mentioned materials are mixed by a mixer to obtain a mixed material. In practice, the execution subject may mix the mineral salts, maltodextrin and compound food additives in the above-mentioned materials by an IBC (Intermediate Bulk Container) lifting mixer to obtain a mixed material. The mixing time may be 10 min. The mixing speed may be 10 rpm / min.

[0036] Step 103, preparing the mixed material and the stirred oil to obtain a prepared nutrient solution.

[0037] In some embodiments, the execution entity may prepare the mixed material and the stirred oil to obtain a prepared nutrient solution.

[0038] Optionally, the above materials may also include white sugar and egg white powder.

[0039] In some optional implementations of some embodiments, the execution subject may prepare the mixed material and the stirred oil to obtain a prepared nutrient solution by performing the following steps:

[0040] In the first step, add reverse osmosis water to the mixing tank.

[0041] The second step is to start the online mixer and the stirring paddle included in the mixing tank. In practice, after adding the reverse osmosis water, the execution body can start the mixing tank for stirring.

[0042] The third step is to add stabilizers, white sugar, maltodextrin and protein powder, stirred oil, mixed materials and flavors into the mixing tank in sequence during the stirring process. Among them, the above-mentioned stabilizer can be a chemical that increases the stability of solutions, colloids, solids, mixtures, etc. The above-mentioned stabilizer can include microcrystalline cellulose and sodium carboxymethyl cellulose. The above-mentioned stabilizer can slow down the stratification of the nutrient solution. Specifically, during the stirring process, first, the above-mentioned execution body can add stabilizers and stir them in a cycle for a first preset stirring time. Then, the above-mentioned execution body can add white sugar, and then add maltodextrin and protein powder alternately, and stir them in a cycle for a second preset stirring time. After that, the above-mentioned execution body can add stirred oil circulation and mixed materials in sequence, and stir them in a cycle for a third preset stirring time. Finally, the above-mentioned execution body can add edible flavors. Among them, the above-mentioned first preset stirring time, the above-mentioned second preset stirring time and the above-mentioned third preset stirring time can all be greater than 5 minutes.

[0043] The fourth step is to cool the material after stirring in the mixing tank to obtain the prepared nutrient solution. In practice, the execution entity can cool the material after stirring in the mixing tank by an indirect heat exchange process to obtain the prepared nutrient solution. The temperature of the prepared nutrient solution can be less than 25°C. The pH range of the prepared nutrient solution can be 7.7 to 8.2. The density range of the prepared nutrient solution can be 1.065g / ml to 1.075g / ml. The dry matter content range of the prepared nutrient solution can be 20% to 23%. The vitamin C content of the prepared nutrient solution is greater than or equal to 30mg / 100ml.

[0044] Furthermore, the execution entity may also perform density and dry matter tests on the prepared nutrient solution to determine whether additional reverse osmosis water is needed.

[0045] Step 104, homogenizing and sterilizing the prepared nutrient solution to obtain the nutrient solution.

[0046] In some embodiments, the execution entity may perform homogenization and sterilization treatment on the prepared nutrient solution to obtain the nutrient solution.

[0047] In some optional implementations of some embodiments, the execution subject may perform homogenization and sterilization treatment on the prepared nutrient solution to obtain the nutrient solution by performing the following steps:

[0048] The first step is to perform pre-homogenization on the prepared nutrient solution by a preset pre-homogenization pressure and a preset pre-homogenization temperature to obtain a pre-homogenized nutrient solution. The preset pre-homogenization pressure may range from 450 bar to 550 bar. The preset pre-homogenization temperature may range from 60°C to 70°C. Before pre-homogenization, the executive body may filter the prepared nutrient solution to obtain a filtered nutrient solution. In practice, the executive body may filter the prepared nutrient solution through a duplex filter. The duplex filter may be made of 316L stainless steel. The pore size of the duplex filter may be 1 mm.

[0049] The second step is to sterilize the pre-homogenized nutrient solution to obtain the sterilized nutrient solution. In practice, the execution entity can perform ultra-high temperature sterilization on the pre-homogenized nutrient solution to obtain the sterilized nutrient solution. The sterilization temperature can range from 135°C to 145°C. The flow rate of the liquid during the sterilization process can range from 9500L / h to 10500L / h. The ultra-high temperature sterilization time can be controlled by controlling the flow rate.

[0050] The third step is to perform post-homogenization treatment on the sterilized nutrient solution by a preset post-homogenization pressure and a preset post-homogenization temperature to obtain a nutrient solution. The preset post-homogenization pressure may range from 180 bar to 220 bar. The preset post-homogenization temperature may range from 60°C to 70°C.

[0051] Optionally, the above execution entity may further perform the following steps:

[0052] The first step is to perform aseptic filling treatment on the above nutrient solution to obtain the filled nutrient solution. Before filling, the above execution entity can sterilize the product pipeline system of the filling machine online with steam and sterilize the filling aseptic warehouse with high-temperature hydrogen peroxide gas. In practice, the above execution entity can perform aseptic filling treatment on the above nutrient solution through the filling machine to obtain the filled nutrient solution.

[0053] The second step is to perform nitrogen filling and film sealing on the nutrient solution after filling to obtain the film-sealed nutrient solution. In practice, the execution body can fill the nutrient solution after filling with nitrogen for nitrogen protection. Then, the execution body can pass the aluminum film sterilized by hydrogen peroxide gas through the high temperature bottle mouth to form a seal to obtain the film-sealed nutrient solution.

[0054] The third step is to perform a leak detection process on the nutrient solution after film sealing to obtain a leak detection result. The leak detection result can indicate that there is no leakage or there is a leak. In practice, the execution subject can perform a leak detection process on the nutrient solution after film sealing by a leak detector to obtain a leak detection result.

[0055] The fourth step is to cap the sealed nutrient solution according to the leak detection result to obtain the capped nutrient solution. In practice, in response to the leak detection result indicating no leakage, the execution subject caps the sealed nutrient solution to obtain the capped nutrient solution.

[0056] The fifth step is to perform a foreign matter detection process on the nutrient solution after the cap is added to obtain a foreign matter detection result. The foreign matter detection result can indicate the presence or absence of foreign matter. In practice, the execution subject can perform a foreign matter detection process on the nutrient solution after the cap is added by an X-ray machine to obtain a foreign matter detection result.

[0057] Step 6: According to the foreign matter detection result, the capped nutrient solution is packaged to obtain packaged nutrient solution. In practice, in response to the foreign matter detection result indicating that no foreign matter exists, the execution subject performs a packaging process on the capped nutrient solution to obtain packaged nutrient solution.

[0058] Therefore, the nutrient solution can be packaged through filling, nitrogen filling, film sealing, leak detection, foreign matter detection and packaging, so as to facilitate subsequent storage and transfer.

[0059] Continuing, when preparing complete nutrient solution for special medical purposes, there is further the following technical problem 2: when errors occur in the preparation process (for example, insufficient stirring or incorrect placement of materials), stratification of the nutrient solution may occur, further affecting the absorption and utilization of the nutrients in the nutrient solution. In response to the above technical problem 2, the conventional solution is generally: the staff checks whether stratification of the nutrient solution occurs. However, the above conventional solution still has the following problem: when the color difference of the several parts of the nutrient solution is small, the staff cannot accurately identify whether stratification occurs.

[0060] Optionally, the above execution entity may further perform the following steps:

[0061] The first step is to collect and process the nutrient solution through a camera to obtain a nutrient solution image, wherein the camera can be arranged on any side of the nutrient solution, and the camera direction of the camera is parallel to the horizontal direction of the nutrient solution.

[0062] The second step is to preprocess the nutrient solution image to obtain a preprocessed nutrient solution image. In practice, the execution subject may perform denoising and / or contrast enhancement on the nutrient solution image to obtain a preprocessed nutrient solution image. This can improve the image quality and facilitate subsequent image recognition and analysis.

[0063] The third step is to perform edge detection on the pre-processed nutrient solution image to obtain edge detection information of the nutrient solution image. The edge detection information of the nutrient solution image may include at least one edge region information. In practice, the execution subject may perform edge detection on the pre-processed nutrient solution image by using Canny edge detection or Sobel operator to obtain edge detection information of the nutrient solution image. Thus, the interface between different layers will appear as an obvious edge, so that it can be detected whether the nutrient solution has a layered interface.

[0064] In the fourth step, the pre-processed nutrient solution image is segmented according to the edge detection information of the nutrient solution image to obtain at least one nutrient solution segmented image. In practice, the execution subject may segment the edge region corresponding to each edge region information in the at least one edge region information to obtain at least one nutrient solution segmented image. Thus, the pre-processed nutrient solution image may be segmented based on the edge, and each interface may be divided into a separate image.

[0065] The fifth step is to perform feature extraction processing on each of the at least one nutrient solution segmentation image to obtain feature information of the nutrient solution segmentation image. In practice, the execution subject may perform feature extraction processing on each of the at least one nutrient solution segmentation image to obtain feature information of the nutrient solution segmentation image through various feature extraction algorithms. The feature extraction algorithms may include but are not limited to: color histogram, HSV (hue, saturation and brightness) or HSL (hue, saturation and brightness) color space, grayscale co-occurrence matrix, local binary pattern.

[0066] The sixth step is to determine the similarity of any two nutrient solution segmentation image feature information in the at least one nutrient solution segmentation image feature information obtained. In practice, the execution subject may determine the similarity of any two nutrient solution segmentation image feature information in the at least one nutrient solution segmentation image feature information obtained according to a similarity algorithm. The similarity algorithm may include but is not limited to cosine similarity, hash algorithm and Euclidean distance.

[0067] In step 7, in response to the similarity between any two nutrient solution segmentation image feature information being less than or equal to a preset similarity threshold, the nutrient solution is moved to a waste liquid tank by a grabbing device. The preset similarity threshold may be a pre-set similarity threshold. The preset nutrient solution stratification information may be information characterizing the existence of stratification in the nutrient solution.

[0068] The above-mentioned related contents, as an inventive point of an embodiment of the present disclosure, solve the second technical problem "When errors occur in the preparation process (for example, insufficient stirring or material placement errors), nutrient solution stratification may occur, further affecting the absorption and utilization of nutrients in the nutrient solution". The factors that further affect the absorption and utilization of nutrients in the nutrient solution are often as follows: When errors occur in the preparation process (for example, insufficient stirring or material placement errors), nutrient solution stratification may occur. If the above-mentioned factors are solved, the effect of maintaining the absorption and utilization of nutrients in the nutrient solution can be achieved. In order to achieve this effect, the present disclosure can collect images of nutrient solution and pre-process the collected nutrient solution images to improve the image quality. And edge detection is performed on the nutrient solution image, and image segmentation is performed according to the edge detection result, and the similarity of each image after segmentation is detected to determine whether the above nutrient solution is stratified according to the size of the similarity. Finally, when it is determined that there is a similarity less than or equal to the preset similarity threshold, that is, when there is a small similarity between two areas, it is determined that the nutrient solution is stratified, that is, the nutrient solution is unqualified, and the above nutrient solution is moved to the waste liquid tank. Therefore, the above stratification detection method can be used to determine whether the nutrient solution is stratified, and the nutrient solution with stratification can be removed, thereby leaving the nutrient solution without stratification, thereby maintaining the absorption and utilization of the nutrients in the nutrient solution.

[0069] According to experimental data, the nutrient solution prepared by the above nutrient solution preparation method is qualified in all indicators after being stored for 12 months in an environment of temperature 25±2°C and humidity RH60±10%. At the same time, the change trends of various nutrients in nutrient solutions of different filling specifications (200ml / 500ml) are basically the same.

[0070] In order to prove the effect of the nutrient solution prepared by the above nutrient solution preparation method, the following test methods and test results are provided.

[0071] First, two different nutrient solutions were prepared on three different dates. They were stored for 12 months at a temperature of 25±2°C and a humidity of RH60±10%. The specific experimental nutrient solution information is shown in the following table:

[0072]

[0073] The test results are as follows:

[0074] The decay rate ranges for protein, fat, linoleic acid, linolenic acid and carbohydrates are shown in the following table:

[0075]

[0076] The test results show that there is no significant change in nutritional indicators such as protein, fat, linoleic acid, α-linolenic acid and carbohydrates.

[0077] The range of mineral attenuation rates is shown in the following table:

[0078]

[0079]

[0080]

[0081] The test results show that there is no significant change in nutrient indicators such as minerals.

[0082] In addition, experiments have proved that the attenuation of vitamins in this nutrient solution is within a controllable narrow range, meeting the product quality requirements.

[0083] Finally, according to the test results, it can be concluded that the nutrient solution prepared by the above nutrient solution preparation method is stored for 12 months at a temperature of 25±2°C and a humidity of RH60±10%, and all indicators are qualified. And the energy density of the nutrient solution prepared by the above nutrient solution preparation method can reach 1kcal / ml. Therefore, the stability of the nutrient solution prepared by the above nutrient solution preparation method is good.

[0084] The above-mentioned embodiments of the present disclosure have the following beneficial effects: the nutrient solution prepared by the nutrient solution preparation method of some embodiments of the present disclosure can still maintain the physical and chemical stability of the nutrient solution on the basis of adding minerals, thereby improving the compliance, taste and appearance of the nutrient solution, and maintaining the absorption and utilization of the nutrients in the nutrient solution. Specifically, the reasons that affect the absorption and utilization of the nutrients in the nutrient solution are: the increase of minerals in the nutrients, the increase of metal ion concentration, the emulsion particles in the nutrient solution are more inclined to aggregate with each other, the thermal stability is reduced, stratification and precipitation occur, the physical stability is poor, and then the chemical stability is poor, resulting in poor compliance, taste and appearance of the nutrient solution. Based on this, the nutrient solution preparation method of some embodiments of the present disclosure, first, obtain materials and stirred oil. Among them, the above-mentioned materials include mineral salts and maltodextrin. Thus, the raw materials for preparing the nutrient solution can be obtained for subsequent preparation. Then, the mineral salts and maltodextrin in the above-mentioned materials are mixed to obtain the mixed material. Thus, after the mineral salts are mixed and diluted by maltodextrin, the subsequent local mineral concentration is avoided to be too high, causing protein denaturation. Afterwards, the mixed material and the stirred oil are prepared to obtain a prepared nutrient solution. Thus, the material and the oil can be prepared to obtain a prepared nutrient solution. Finally, the prepared nutrient solution is homogenized and sterilized to obtain a nutrient solution. Thus, the prepared nutrient solution can be homogenized and sterilized, and the bacteria in the nutrient solution can be reduced by the sterilization treatment, and the fluidity of the nutrient solution can be improved by the homogenization treatment, and the stability of the nutrient solution can be increased, so that the nutrients in the nutrient solution are more evenly distributed. Therefore, the nutrient solution prepared by the nutrient solution preparation method of some embodiments of the present disclosure can still maintain the stability of the nutrient solution on the basis of adding minerals, thereby improving the compliance, taste and appearance of the nutrient solution, and maintaining the absorption and utilization of the nutrients in the nutrient solution.
