Description

Technical Field

[0001] This invention belongs to the field of nutritional meal replacement food formulation technology, and in particular relates to a traditional Chinese medicine formula and preparation method for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement. Background Technology

[0002] Due to their nourishing properties, donkey-hide gelatin-based foods are often used for daily nutritional supplementation and dietary conditioning for women. With increasing demand for sugar control, weight management, and meal replacements, consumers' requirements for donkey-hide gelatin products have shifted from simple nourishment to low sugar, high nutritional value, increased satiety, and convenient preparation. Traditional donkey-hide gelatin pastes, oral liquids, and solid beverages tend to focus on nourishment and supplementation, making it difficult to simultaneously meet the needs of meal replacement, protein supplementation, dietary fiber intake, and traditional Chinese medicine dietary therapy. Therefore, it is necessary to provide a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula and preparation method, enabling donkey-hide gelatin to synergistically combine with protein nutrition, complex dietary fiber, and medicinal and edible components, thereby improving the problems of traditional donkey-hide gelatin products such as being greasy, high in sugar, insufficiently satiating, and poorly suited for meal replacement.

[0003] (1) Traditional donkey-hide gelatin products are usually composed of donkey-hide gelatin, sugars, and excipients. Some products add white sugar, rock sugar, and syrups to improve the taste, resulting in high sugar content, which is not conducive to long-term consumption by people who control blood sugar and lose fat. At the same time, donkey-hide gelatin has a sticky texture, which can easily cause clumping, slow dissolution, and a heavy taste when consumed alone. For people with weak spleen and stomach function, the single donkey-hide gelatin nourishing mode can easily lead to a burden on their diet, making it difficult to meet the needs of strengthening the spleen, removing dampness, and serving as a daily meal replacement. Therefore, existing donkey-hide gelatin products have problems such as insufficient low sugar compatibility, poor dispersibility when mixed, weak meal replacement properties, and a heavy burden on the diet.

[0004] (2) Most common meal replacement powders mainly consist of soy protein isolate, milk powder, maltodextrin, and dietary fiber, which can provide certain protein nutrition and satiety. However, they lack a traditional Chinese medicine (TCM) formulation structure tailored to women's needs for qi and blood deficiency, spleen deficiency with dampness, edema, fatigue, and daily dietary nourishment. Some meal replacement products only pursue satiety and calorie control, failing to combine the blood-nourishing properties of donkey-hide gelatin, the spleen-strengthening and dampness-removing properties of food and medicine, the long-lasting satiety effect of compound dietary fiber, and the low-sugar sweetness system. This results in a single functional level of the product, making it difficult to simultaneously achieve nutritional meal replacement, low-sugar preparation, and dietary nourishment. Therefore, existing meal replacement powders suffer from insufficient TCM dietary nourishment, limited satiety duration, poor low-sugar nutritional synergy, and low integration with donkey-hide gelatin as a meal replacement. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a traditional Chinese medicine formula and preparation method for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement. This method involves compounding donkey-hide gelatin blood-nourishing components, nutritional protein components, dietary fiber components, and traditional Chinese medicine dietary components. Through low-temperature drying and ultra-fine pulverization of medicinal and edible raw materials, low-temperature swelling and spray drying modification of donkey-hide gelatin, stepwise premixing of dietary fiber, and three-dimensional total mixing processes, a donkey-hide gelatin nutritional meal replacement powder with good dispersibility, long satiety time, and suitability as a meal replacement is obtained. This improves upon the problems of traditional donkey-hide gelatin products such as greasiness, clumping during reconstitution, and insufficient meal replacement properties, while simultaneously meeting the needs for protein nutrition, dietary fiber satiety, and traditional Chinese medicine dietary compatibility.

[0006] The technical solution adopted in this invention is as follows: a traditional Chinese medicine formula for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement, comprising the following ingredients by weight: 18-28 parts soy protein isolate, 10-18 parts skim milk powder, 12-22 parts xylitol, 6-12 parts maltodextrin, 5-10 parts inulin, 4.9 parts cocoa powder, 0.3-0.8 parts yellow gelatin, 2-5 parts konjac powder, 5-9 parts resistant dextrin, 2.5-5 parts donkey-hide gelatin, 3-7 parts coix seed powder, 3-7 parts yam powder, 2-6 parts white hyacinth bean powder, 2-6 parts poria cocos powder, 2-5 parts fox nut powder, 1.5-4 parts lily powder, 0.5-2 parts artificially cultivated ginseng powder, 0.3-1 parts compound nutrients, and 0.05-0.12 parts chocolate flavoring.

[0007] Furthermore, the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement TCM formula is composed of donkey-hide gelatin blood-nourishing components, nutritional protein components, dietary fiber components, and TCM dietary therapy components; the donkey-hide gelatin blood-nourishing components include donkey-hide gelatin and yellow gelatin; the nutritional protein components include soy protein isolate, skim milk powder, maltodextrin, xylitol, cocoa powder, and compound nutrients; the dietary fiber components include inulin, konjac powder, and resistant dextrin; the TCM dietary therapy components include coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder, and artificially cultivated ginseng powder.

[0008] Furthermore, the soy protein isolate is food-grade soy protein isolate; the skim milk powder is food-grade skim milk powder; and the xylitol, maltodextrin, inulin, cocoa powder, gelatin, konjac powder, resistant dextrin, donkey-hide gelatin, coix seed, yam, white hyacinth bean, poria cocos, euryale seed, lily bulb, and artificially cultivated ginseng are all food-grade raw materials.

[0009] Furthermore, the compound nutrient is composed of vitamin C, vitamin E, ferrous sulfate, zinc sulfate and vitamin D.

[0010] This invention also provides a method for preparing a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula, which specifically includes the following steps: Step 1: Weigh out Job's tears, yam, white hyacinth bean, poria cocos, fox nut, lily bulb and artificially cultivated ginseng, remove mud, impurities and moldy parts, wash and drain to obtain clean medicinal and edible materials; Step 2: Place the cleaned medicinal and edible materials in a low-temperature hot air drying oven and dry them until the moisture content is ≤6% to obtain low-moisture medicinal and edible raw materials; Step 3: The low-moisture medicinal and edible raw materials are ultra-finely pulverized and sieved to obtain coix seed powder, yam powder, white hyacinth bean powder, poria powder, euryale seed powder, lily powder and artificially cultivated ginseng powder; Step 4: Weigh the donkey-hide gelatin, crush it into coarse particles, add purified water, and let it swell under low temperature and water-sealed conditions. Stir until a uniform donkey-hide gelatin sol is formed. Step 5: Add xylitol to the donkey-hide gelatin sol and stir evenly to obtain donkey-hide gelatin xylitol composite sol; Step 6: Spray dry the xylitol composite sol of donkey-hide gelatin, collect the dried powder and sieve it to obtain modified donkey-hide gelatin ultrafine powder; Step 7: Weigh xylitol, inulin, konjac flour, resistant dextrin and yellow gelatin and mix them to obtain the first premix; Step 8: Weigh out soy protein isolate, skim milk powder, maltodextrin, cocoa powder and compound nutrients and mix them to obtain the second premix; Step 9: Add coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder and artificially cultivated ginseng powder to a three-dimensional mixer and mix to obtain a traditional Chinese medicine dietary powder mixture. Step 10: Put the first premix, the second premix, the modified donkey-hide gelatin ultrafine powder and the traditional Chinese medicine food and nutrition mixture into a three-dimensional mixer, mix them at room temperature, then add chocolate flavoring and continue mixing to obtain the finished product powder of the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula. Step 11: Pack and seal the finished product powder of spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula in a clean environment with relative humidity ≤45% to obtain spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement powder.

[0011] Furthermore, in step 2, the drying temperature of the low-temperature hot air drying oven is 45-55℃.

[0012] Furthermore, in step 3, the mesh size of the sieve used for sieving is 250 mesh.

[0013] Furthermore, in step 4, the temperature of the low-temperature water-proof sealing condition is 40-50℃, and the swelling time is 3-4 hours.

[0014] Furthermore, in step 6, the inlet air temperature of the spray dryer is 130°C and the outlet air temperature is 70°C.

[0015] Furthermore, in step 7, the mixing time is 10-15 minutes; in step 8, the mixing time is 15 minutes.

[0016] Furthermore, in step 10, the mixing time at room temperature is 25-35 minutes, and the continued mixing time after adding chocolate flavoring is 5 minutes.

[0017] The beneficial effects of this invention are as follows: (1) Using donkey-hide gelatin, yellow gelatin, artificially cultivated ginseng powder, poria powder, yam powder, white hyacinth bean powder, coix seed powder, euryale seed powder and lily powder to form a blood-nourishing and spleen-strengthening system of donkey-hide gelatin. Ginseng invigorates qi, poria strengthens the spleen and eliminates dampness, yam gently nourishes the spleen and stomach, white hyacinth bean strengthens the spleen and harmonizes the middle, coix seed promotes diuresis and eliminates dampness, euryale seed consolidates the spleen and astringes, and lily nourishes yin and harmonizes as the basis of the combination. This makes the nourishing components of donkey-hide gelatin coordinate with the spleen-strengthening and dampness-eliminating components, so as to achieve the technical effect of nourishing without being greasy, strengthening the spleen without being stagnant, and reducing the burden of eating as a meal replacement. This solves the technical problems of traditional donkey-hide gelatin foods being too greasy, not adaptable to the spleen and stomach, and difficult to use as a daily meal replacement for a long time.

[0018] (2) A nutritional protein and low-sugar sweetness system is constructed by using soy protein isolate, skim milk powder, maltodextrin, compound nutrients and xylitol. Nutritional fortification is carried out by vitamin C, vitamin E, ferrous sulfate, zinc sulfate and vitamin D in the compound nutrients, so that animal and plant proteins, minerals and vitamins form a compound nutritional support. At the same time, xylitol is used to replace sucrose to reduce the sugar burden, thereby achieving the technical effects of improving the nutritional integrity of meal replacement, reducing the blood sugar burden and being suitable for people who control blood sugar and weight. This solves the technical problems of high sugar content in traditional donkey-hide gelatin food, insufficient nutritional fortification of ordinary meal replacement powder and poor long-term applicability of meal replacement.

[0019] (3) A composite dietary fiber system is formed by using inulin, konjac powder and resistant dextrin. The process of low-temperature water-sealed swelling of donkey-hide gelatin, xylitol compounding, spray drying, ultra-fine pulverization of medicinal and edible raw materials and step-by-step premixing is adopted to make the dietary fiber uniformly dispersed in the powder, so that donkey-hide gelatin is formed into modified donkey-hide gelatin ultrafine powder. This achieves the technical effects of improving the dispersibility of warm water reconstitution, reducing the agglomeration and sedimentation of donkey-hide gelatin, prolonging the satiety maintenance time and improving the taste. It solves the technical problems of easy agglomeration of donkey-hide gelatin powder when directly reconstituted, easy clumping of konjac powder, large sedimentation of medicinal and edible powders and insufficient satiety of ordinary meal replacements.

The spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula is composed of donkey-hide gelatin blood-nourishing components, nutritional protein components, dietary fiber components, and traditional Chinese medicine dietary therapy components. The donkey-hide gelatin blood-nourishing components include donkey-hide gelatin and yellow gelatin; the nutritional protein components include soy protein isolate, skim milk powder, maltodextrin, xylitol, cocoa powder, and compound nutrients; the dietary fiber components include inulin, konjac powder, and resistant dextrin; and the traditional Chinese medicine dietary therapy components include coix seed powder, yam powder, white hyacinth bean powder, poria cocos powder, fox nut powder, lily bulb powder, and artificially cultivated ginseng powder. The preparation method of the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula is as follows: Step 1: Weigh out Job's tears, yam, white hyacinth bean, poria cocos, fox nut, lily bulb and artificially cultivated ginseng, remove mud, impurities and moldy parts, wash and drain to obtain clean medicinal and edible materials; Step 2: Place the cleaned medicinal and edible materials in a low-temperature hot air drying oven and dry them at 50°C until the moisture content is ≤6% to obtain low-moisture medicinal and edible raw materials; Step 3: The low-moisture medicinal and edible raw materials are ultra-finely pulverized and passed through a 250-mesh sieve to obtain coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder and artificially cultivated ginseng powder; Step 4: Weigh 3.5 parts of donkey-hide gelatin, crush it into coarse particles, add 12 parts of purified water, and swell it in a water-sealed environment at 45℃ for 3.5 hours. Stir until a uniform donkey-hide gelatin sol is formed. Step 5: Add 3 parts xylitol to the donkey-hide gelatin sol and stir evenly to obtain donkey-hide gelatin xylitol composite sol; Step 6: Spray dry the xylitol composite sol of donkey-hide gelatin. The inlet air temperature of the spray dryer is 130℃ and the outlet air temperature is 70℃. Collect the dried powder and pass it through a 250-mesh sieve to obtain modified donkey-hide gelatin ultrafine powder. Step 7: Weigh 14 parts xylitol, 7 parts inulin, 3 parts konjac powder, 7 parts resistant dextrin and 0.5 parts yellow gelatin, add them to a two-dimensional mixer and mix for 12 minutes to obtain the first premix. Step 8: Weigh 23 parts soy protein isolate, 14 parts skim milk powder, 9 parts maltodextrin, 4.9 parts cocoa powder and 0.6 parts compound nutrients, add them to a two-dimensional mixer and mix for 15 minutes to obtain the second premix. Step 9: Add 5 parts of coix seed powder, 5 parts of yam powder, 4 parts of white hyacinth bean powder, 4 parts of poria powder, 3 parts of fox nut powder, 2.5 parts of lily powder and 1 part of artificially cultivated ginseng powder obtained in Step 3 into a three-dimensional mixer and mix for 10 minutes to obtain a traditional Chinese medicine dietary powder mixture. Step 10: Put the first premix, the second premix, the modified donkey-hide gelatin ultrafine powder and the traditional Chinese medicine food and nutrition mixture into a three-dimensional mixer and mix for 30 minutes at room temperature. Then add 0.08 parts of chocolate flavoring and continue mixing for 5 minutes to obtain the finished product powder of the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula. Step 11: Pack and seal the finished product powder of spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula in a clean environment with relative humidity ≤45% to obtain spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement powder.

[0026] Regarding parameter adjustments: In step 4, the low-temperature, water-tight, sealed swelling time of the donkey-hide gelatin is used to adjust the uniformity of the gelatin sol. When the swelling time is less than 3 hours, the coarse particles of the donkey-hide gelatin do not absorb enough water, and the powder obtained from subsequent spray drying is prone to forming clumps when mixed. When the swelling time is greater than 4 hours, the production cycle is prolonged, and the viscosity of the donkey-hide gelatin sol increases, which is not conducive to stable spraying. In step 7, the premixing order of inulin, konjac powder, and resistant dextrin is used to adjust the dispersibility. When konjac powder comes into direct contact with liquid, it easily absorbs water quickly to form an outer gel and clump together. Dry mixing it with xylitol, inulin, and resistant dextrin first, and then mixing it together, can improve the dispersion uniformity of konjac powder in the finished powder.

[0027] Example 2: This example provides a traditional Chinese medicine formula for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement. The formula includes the following ingredients by weight: 18 parts soy protein isolate, 10 parts skim milk powder, 12 parts xylitol, 6 parts maltodextrin, 10 parts inulin, 4.9 parts cocoa powder, 0.3 parts yellow gelatin, 5 parts konjac powder, 9 parts resistant dextrin, 2.5 parts donkey-hide gelatin, 7 parts coix seed powder, 7 parts yam powder, 6 parts white hyacinth bean powder, 6 parts poria cocos powder, 5 parts fox nut powder, 4 parts lily powder, 2 parts artificially cultivated ginseng powder, 1 part compound nutrients, and 0.08 parts chocolate flavoring. The preparation method is as follows: Step 1: Weigh out Job's tears, yam, white hyacinth bean, poria cocos, fox nut, lily bulb and artificially cultivated ginseng, remove mud, impurities and moldy parts, wash and drain to obtain clean medicinal and edible materials; Step 2: Place the cleaned medicinal and edible materials in a low-temperature hot air drying oven and dry them at 45°C until the moisture content is ≤6% to obtain low-moisture medicinal and edible raw materials; Step 3: The low-moisture medicinal and edible raw materials are ultra-finely pulverized and passed through a 250-mesh sieve to obtain coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder and artificially cultivated ginseng powder; Step 4: Weigh 2.5 parts of donkey-hide gelatin, crush it into coarse particles, add 10 parts of purified water, and let it swell for 3 hours under a water-sealed condition at 40℃.

Step 11: Pack and seal the finished product powder of spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula in a clean environment with relative humidity ≤45% to obtain spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement powder.

[0028] Example 3: This example provides a traditional Chinese medicine formula for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement. The formula includes the following ingredients by weight: 28 parts soy protein isolate, 18 parts skim milk powder, 22 parts xylitol, 12 parts maltodextrin, 5 parts inulin, 4.9 parts cocoa powder, 0.8 parts yellow gelatin, 2 parts konjac powder, 5 parts resistant dextrin, 5 parts donkey-hide gelatin, 3 parts coix seed powder, 3 parts yam powder, 2 parts white hyacinth bean powder, 2 parts poria cocos powder, 2 parts fox nut powder, 1.5 parts lily powder, 0.5 parts artificially cultivated ginseng powder, 0.3 parts compound nutrients, and 0.08 parts chocolate flavoring. The preparation method is as follows: Step 1: Weigh out Job's tears, yam, white hyacinth bean, poria cocos, fox nut, lily bulb and artificially cultivated ginseng, remove mud, impurities and moldy parts, wash and drain to obtain clean medicinal and edible materials; Step 2: Place the cleaned medicinal and edible materials in a low-temperature hot air drying oven and dry them at 55°C until the moisture content is ≤6% to obtain low-moisture medicinal and edible raw materials; Step 3: The low-moisture medicinal and edible raw materials are ultra-finely pulverized and passed through a 250-mesh sieve to obtain coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder and artificially cultivated ginseng powder; Step 4: Weigh 5 parts of donkey-hide gelatin, crush it into coarse particles, add 15 parts of purified water, and let it swell for 4 hours under a water-sealed condition at 50℃. Stir until a uniform donkey-hide gelatin sol is formed. Step 5: Add 4 parts xylitol to the donkey-hide gelatin sol and stir evenly to obtain donkey-hide gelatin xylitol composite sol; Step 6: Spray dry the xylitol composite sol of donkey-hide gelatin. The inlet air temperature of the spray dryer is 130℃ and the outlet air temperature is 70℃. Collect the dried powder and pass it through a 250-mesh sieve to obtain modified donkey-hide gelatin ultrafine powder. Step 7: Weigh 18 parts xylitol, 5 parts inulin, 2 parts konjac powder, 5 parts resistant dextrin and 0.8 parts yellow gelatin, add them to a two-dimensional mixer and mix for 10 minutes to obtain the first premix. Step 8: Weigh 28 parts of soy protein isolate, 18 parts of skim milk powder, 12 parts of maltodextrin, 4.9 parts of cocoa powder and 0.3 parts of compound nutrients, add them to a two-dimensional mixer and mix for 15 minutes to obtain the second premix. Step 9: Add 3 parts of coix seed powder, 3 parts of yam powder, 2 parts of white hyacinth bean powder, 2 parts of poria powder, 2 parts of fox nut powder, 1.5 parts of lily powder and 0.5 parts of artificially cultivated ginseng powder to a three-dimensional mixer and mix for 10 minutes to obtain a traditional Chinese medicine dietary powder mixture. Step 10: Put the first premix, the second premix, the modified donkey-hide gelatin ultrafine powder and the traditional Chinese medicine food and nutrition mixture into a three-dimensional mixer and mix for 25 minutes at room temperature. Then add 0.08 parts of chocolate flavoring and continue mixing for 5 minutes to obtain the finished product powder of the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula. Step 11: Pack and seal the finished product powder of spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula in a clean environment with relative humidity ≤45% to obtain spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement powder.

[0029] Regarding parameter adjustments: The low-temperature drying of the medicinal and edible raw materials in steps 1 to 3 is used to balance drying efficiency and powder flavor preservation. When the drying temperature is below 45℃, the drying time is prolonged and the moisture content of the powder is not easily controlled stably; when the drying temperature is above 55℃, the aroma and color of some raw materials are easily affected. The three-dimensional mixing time in step 10 is used to adjust the uniformity of the finished powder. When the mixing time is below 25 minutes, the distribution of the blood-nourishing components, traditional Chinese medicine nutritional components, and dietary fiber components of donkey-hide gelatin is uneven; when the mixing time is above 35 minutes, the frictional heating of the powder increases, which easily causes the aroma to dissipate.

[0031] The difference between Comparative Example 1 and Example 1 is that no coix seed powder, yam powder, white hyacinth bean powder, poria powder, euryale seed powder, lily powder, and artificially cultivated ginseng powder were added; the rest of the ingredients were the same as in Example 1. The difference between Comparative Example 2 and Example 1 is that: the donkey-hide gelatin was not subjected to low-temperature swelling and spray drying modification treatment, but was directly crushed and added to the total mixture. The rest of the process was the same as in Example 1. The difference between Comparative Example 3 and Example 1 is that no inulin, konjac flour and resistant dextrin were added, while the rest were the same as in Example 1; The difference between Comparative Example 4 and Example 1 is that xylitol was completely replaced with sucrose, while the rest was the same as in Example 1.

[0032] Dispersibility test: Take 40g of the finished powder prepared in Examples 1-4 and Comparative Examples 1-4 respectively, add it to 400mL of warm water at 45℃, stir for 30s and observe the clumping situation, and record the complete dispersion time and the amount of sediment at the bottom of the cup. The results are shown in Table 1.

[0033] Satiety test: Subjects under the same conditions were selected to undergo a single meal replacement experience. They consumed the finished powder preparations prepared in Examples 1-4 and Comparative Examples 1-4 respectively. The subjective satiety duration of the subjects was recorded. The results are shown in Table 1.

[0034] Feedback test: Thirty subjects with sub-health symptoms related to spleen deficiency and dampness and qi and blood deficiency were selected. For 30 consecutive days, they replaced one meal with the finished powder prepared in Examples 1-4 and Comparative Examples 1-4. The percentage of subjects who reported improved stool consistency, reduced fatigue and improved complexion was recorded. The results are shown in Table 1.

[0035] Table 1. Performance test results of the spleen-strengthening and blood-nourishing type of donkey-hide gelatin nutritional meal replacement traditional Chinese medicine formula:

[0036] Table 1 shows that, compared with Comparative Examples 1-4, the spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement TCM formulas prepared in Examples 1-4 have shorter complete dispersion time, lower sedimentation at the bottom of the cup, longer satiety maintenance time, and higher improvement rate in trial feedback. This indicates that the modified pretreatment of donkey-hide gelatin, the compounding of dietary fiber, TCM nutritional components, and xylitol low-sugar sweetening system can synergistically improve the product's solubility, satiety, and nutritional experience.

[0037] Comparative Example 1, which did not include coix seed powder, yam powder, white hyacinth bean powder, poria powder, fox nut powder, lily powder, or artificially cultivated ginseng powder, lacked the spleen-strengthening, dampness-removing, qi-tonifying, blood-nourishing, yin-nourishing, and mind-calming dietary combination. The improvement rate reported by the subjects was significantly lower than in Examples 1-4. In Examples 1-4, artificially cultivated ginseng powder and poria powder served as the foundation for qi-tonifying and spleen-strengthening; yam powder, white hyacinth bean powder, coix seed powder, and fox nut powder jointly enhanced spleen-strengthening and dampness-removing effects; and donkey-hide gelatin and lily powder formed a blood-nourishing and yin-nourishing combination, enabling both nutritional support and dietary conditioning in a meal replacement setting.

[0038] Comparative Example 2 did not undergo low-temperature swelling and spray drying modification treatment on the donkey-hide gelatin. When the dry powder was directly mixed with water, it easily formed outer gelatinous clumps, resulting in prolonged complete dispersion time and increased sediment at the bottom of the cup. Examples 1-4 used low-temperature water-sealed swelling to fully gelatinize the donkey-hide gelatin, and then formed modified donkey-hide gelatin ultrafine powder through xylitol compounding and spray drying, which can improve the problems of donkey-hide gelatin clumping and sedimentation when mixed with water.

[0039] Comparative Example 3, which did not contain inulin, konjac powder, or resistant dextrin, lacked the water-absorbing, swelling, and digestion-delaying effects of the complex dietary fiber, resulting in a significantly shorter satiety duration compared to Examples 1-4. Examples 1-4, by using inulin, konjac powder, and resistant dextrin to form a complex dietary fiber system, could increase the viscosity of the prepared system and its residence time in the stomach, thereby enhancing the feeling of fullness.

[0040] Comparative Example 4 replaced all xylitol with sucrose. While the sweet taste was maintained, it was not suitable for long-term use as a meal replacement by people trying to lose weight and control their blood sugar. Furthermore, the rapid energy release from sucrose shortens the duration of subjective satiety. Examples 1-4 used xylitol as a sweetener, combined with complex dietary fiber and protein components, making the product more suitable for use as a low-sugar meal replacement powder.

[0041] The spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement formula prepared in Example 1 has a superior overall effect. This is because 23 parts of soy protein isolate and 14 parts of skim milk powder can provide a relatively stable combination of animal and plant proteins; 17 parts of xylitol, 7 parts of inulin, 3 parts of konjac powder and 7 parts of resistant dextrin can form a low-sugar satiety system; 3.5 parts of donkey-hide gelatin and 0.5 parts of yellow gelatin can provide support for the blood-nourishing and reconstituted taste of donkey-hide gelatin; 5 parts of coix seed powder, 5 parts of yam powder, 4 parts of white hyacinth bean powder, 4 parts of poria cocos powder, 3 parts of fox nut powder, 2.5 parts of lily powder and 1 part of artificially cultivated ginseng powder can form a relatively balanced combination of spleen-strengthening and dampness-removing, qi-tonifying and blood-nourishing, and yin-nourishing and mind-calming dietary nutrition, so that the product has both reconstituted stability, satiety and nutritional properties.

[0042] This invention discloses a traditional Chinese medicine formula and preparation method for a spleen-strengthening and blood-nourishing donkey-hide gelatin nutritional meal replacement. The blood-nourishing components of donkey-hide gelatin provide the basic nourishment, the protein components provide the necessary protein and nutritional fortification, the dietary fiber components enhance satiety and help delay carbohydrate absorption, and the traditional Chinese medicine dietary components form a formula that strengthens the spleen, removes dampness, invigorates qi and nourishes blood, and nourishes yin and calms the mind. Simultaneously, through low-temperature swelling of donkey-hide gelatin, xylitol compounding, spray drying, ultra-fine pulverization of medicinal and edible raw materials, and step-by-step premixing processes, the problems of donkey-hide gelatin clumping, medicinal and edible powder sedimentation, konjac powder agglomeration, and insufficient overall mixing uniformity are improved. This makes the resulting donkey-hide gelatin nutritional meal replacement powder suitable as a low-sugar, long-lasting, and dietaryally nourishing meal replacement product.
