Description

Technical Field

[0001] This invention relates to the field of functional beverage technology, and in particular to an epimedium and polygonatum beverage and its preparation method. Background Technology

[0002] With the upgrading of national health needs and the popularization of the concept of "medicine and food from the same source," functional beverages have become the core growth segment of the beverage market. Traditional beverages generally suffer from the problems of "high sugar, low nutrition, and no function," and long-term consumption can easily lead to metabolic disorders. Existing health drinks mostly focus on a single function (such as iron supplementation and calcium supplementation), lacking a synergistic combination of essential nutrients for the human body, and have obvious technical shortcomings in terms of preserving the active ingredients of raw materials, balancing taste, and optimizing stability.

[0003] Epimedium is a traditional Chinese medicine with the effects of tonifying kidney yang, strengthening muscles and bones, and dispelling wind and dampness. Modern pharmacological studies have shown that its main active ingredient, icariin, has the effects of enhancing immunity, anti-fatigue, and improving cardiovascular function. Polygonatum is also a good product that is both food and medicine, and can replenish qi and nourish yin, strengthen the spleen, moisten the lungs, and benefit the kidneys. It also has the effects of anti-oxidation, anti-aging, enhancing immunity, and regulating blood sugar.

[0004] Currently, most products using these two ingredients as raw materials are in solid dosage form (such as tablets and ointments), which have problems such as slow dissolution and absorption and limited consumption scenarios. A few liquid products have less than 30% dissolution rate of active ingredients due to the lack of optimized extraction process, and the products have poor stability and are prone to precipitation and separation. Therefore, an Epimedium and Polygonatum beverage and its preparation method are proposed to solve the above problems. Summary of the Invention

[0005] (a) Purpose of the invention To address the technical problems existing in the background art, this invention proposes an epimedium and polygonatum beverage and its preparation method. By adding and distributing wolfberry, red dates, yam, trace element supplements and additives, it has the advantages of promoting the absorption and conversion of epimedium glycosides and polygonatum polysaccharides.

[0006] (II) Technical Solution This invention provides an Epimedium and Polygonatum beverage, comprising the following ingredients in the indicated proportions: 5-10 parts Epimedium, 8-15 parts Polygonatum, 3-6 parts Lycium barbarum, 5-8 parts red dates, 4-7 parts Dioscorea opposita, trace element supplements, 2-5 parts white sugar, 1-3 parts honey, additives, and purified water.

[0007] Preferably, the Epimedium is dried leaves that have been baked at 60°C for 2 hours and then pulverized to 20-40 mesh, and the Polygonatum is dried by steaming, slicing and drying until the moisture content is less than 8%, and then pulverized to 30-50 mesh.

[0008] Preferably, the trace element supplement includes 0.02-0.05 parts of zinc gluconate, 0.0001-0.0003 parts of sodium selenite, and 0.005-0.01 parts of manganese sulfate.

[0009] Preferably, the zinc gluconate, sodium selenite, and manganese sulfate are all food-grade.

[0010] Preferably, the additives include 0.1-0.3 parts citric acid, 0.05-0.1 parts vitamin C, 2-4 parts fructooligosaccharides, and 0.5-1 parts β-cyclodextrin.

[0011] Another method for preparing Epimedium and Polygonatum beverage proposed in this invention includes the following steps: 1) Raw material pretreatment: Epimedium was baked at 60℃ for 2 hours and then pulverized to 20 mesh. Polygonatum was steamed at 95℃ for 1 hour and dried to 15% moisture content. This process was repeated 3 times and then cut into 0.5cm thick slices. Dioscorea opposita was peeled, steamed for 20 minutes and then cut into 1cm cubes. Trace elements were dissolved in 50℃ pure water, and β-cyclodextrin was added and stirred for 30 minutes at a speed of 150r / min. The mixture was then stored in the dark to obtain a trace element solution. 2) Synergistic extraction: Add the Epimedium, Polygonatum and Dioscorea opposita from step 1) to the dynamic extraction tank, add wolfberry and red dates, and add purified water and compound enzyme preparation to the dynamic extraction tank in sequence. Enzymatic hydrolysis is carried out at 50℃ for 2 hours. After the enzymatic hydrolysis is completed, filter with a 100-mesh filter cloth to obtain filter residue and primary filtrate. 3) Secondary extraction: Add purified water to the filter residue from step 2), extract at 85°C for 1 hour, and filter with a 100-mesh filter cloth to obtain a secondary filtrate. Mix the primary and secondary filtrates to obtain the extract. 4) Clarification treatment: Add chitosan solution to the extract in step 3), stir evenly, let stand at 25-30℃ for 4-6 hours, and filter with a plate and frame filter to obtain a clear liquid; 5) Addition of trace elements: Slowly add the trace element solution from step 1) to the clarified solution from step 4), stirring during the addition process at a speed of 100 r / min for 20 min. At the same time, nitrogen gas is introduced into the clarified solution to prevent oxidation, thus obtaining the added solution. 6) Preparation: Add white sugar, honey, citric acid, vitamin C and fructooligosaccharides to the liquid in step 5) in sequence, stir at 130-150 r / min for 15-20 min at 30℃ until completely dissolved to obtain the beverage; 7) Sterilization: The beverage from step 6) is sterilized using a combination of ultra-high temperature instantaneous sterilization (UHT) and microwave-assisted sterilization. First, it is sterilized at 120-135℃ for 3-5 seconds, then transferred to a microwave sterilization device (power 800W) for 20-30 seconds, and then rapidly cooled to 25-30℃ to obtain a sterile beverage. 8) Aseptic filling: Using aseptic filling equipment, in a Class 100 cleanroom environment, aseptic beverages are filled into sterilized PET bottles or glass bottles. After filling, the bottles are immediately capped, and the capping pressure is controlled at 0.3-0.5 MPa to obtain the finished product.

[0012] Preferably, in step 2), the weight of the purified water is 5-6 times the total weight of the material inside the dynamic extraction tank; in step 2), the amount of the compound enzyme preparation added is 0.2% of the volume of the purified water; in step 2), the compound enzyme preparation is food-grade cellulase and pectinase, and the ratio of cellulase to pectinase is 1:1; and in step 3), the weight of the purified water is 3-4 times the weight of the filter residue.

[0013] Preferably, in step 4), the amount of chitosan solution is 0.15-0.2% of the extract volume, the concentration of chitosan solution is 1-2%, and it is dissolved in 0.1 mol / L acetic acid.

[0014] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: 1. This Epimedium and Polygonatum beverage and its preparation method involve compounding Epimedium, Polygonatum, and trace elements such as zinc, selenium, and manganese. Zinc promotes the absorption and conversion of icariin, while selenium synergistically enhances antioxidant capacity with Polygonatum polysaccharides, solving the problem of single nutrition in traditional beverages. Furthermore, the finished product exhibits a high retention rate of icariin and a high recovery rate of trace elements. The use of β-cyclodextrin inclusion complexation technology solves the precipitation problem of trace elements and plant polyphenols, improving the stability of the beverage over long periods. The addition of yam and fructooligosaccharides not only enriches the dietary fiber content but also neutralizes the bitterness of Epimedium, improving the beverage's taste.

[0015] 2. The Epimedium and Polygonatum beverage and its preparation method utilize an enzymatic hydrolysis-constant temperature double extraction process to greatly improve the dissolution rate of epimedium glycosides. The composite sterilization process ensures the sterilization effect while avoiding the destruction of active ingredients by high temperature alone. Attached Figure Description

[0016] Figure 1 This is a flowchart illustrating the preparation process of an Epimedium and Polygonatum beverage and its preparation method proposed in this invention. Detailed Implementation

[0017] The present invention proposes an epimedium and polygonatum beverage, comprising the following ingredients in the following proportions: 5-10 parts epimedium, 8-15 parts polygonatum, 3-6 parts wolfberry, 5-8 parts red dates, 4-7 parts yam, trace element supplement, 2-5 parts white sugar, 1-3 parts honey, additives, and purified water.

[0018] Epimedium is dried leaf that has been baked at 60℃ for 2 hours and then pulverized to a fineness of 20-40 mesh. Epimedium has the effects of tonifying kidney yang, strengthening tendons and bones, and dispelling wind and dampness. Modern pharmacological studies have shown that its main active ingredient, icariin, has the effects of enhancing immunity, anti-fatigue, and improving cardiovascular function.

[0019] Polygonatum is prepared by steaming, slicing and drying until the moisture content is less than 8%, and then pulverizing it to 30-50 mesh. The active ingredients in Polygonatum include Polygonatum polysaccharides, flavonoids and saponins. Its rhizome can be used as medicine. It is sweet in taste and neutral in nature. It enters the spleen, lung and kidney meridians and has the effects of nourishing yin and moistening the lungs, tonifying the spleen and replenishing qi, and nourishing the kidneys and replenishing essence.

[0020] Goji berries are rich in goji polysaccharides and carotenoids, which nourish the liver and kidneys, benefit essence and improve eyesight. They can work synergistically with the core ingredients to enhance their nourishing effects, while also adding a natural sweetness.

[0021] Red dates can replenish qi and blood, calm the mind, improve the taste of beverages, making them mellow and sweet, and are rich in vitamins and minerals.

[0022] Yam strengthens the spleen and stomach, aids digestion, and is rich in nutrients such as mucoprotein, which helps improve the nutritional value and viscosity of beverages.

[0023] White sugar and honey provide sweetness and improve the palatability of beverages. Honey also contains a variety of nutrients, increasing the added value of products.

[0024] The trace element supplement includes 0.02-0.05 parts zinc gluconate, 0.0001-0.0003 parts sodium selenite, and 0.005-0.01 parts manganese sulfate. Zinc gluconate, sodium selenite, and manganese sulfate are all food grade. Zinc gluconate can supplement the essential zinc element in the human body, participate in the synthesis of various enzymes, and is crucial for maintaining normal growth and development, immune function, and the taste system. Sodium selenite provides selenium, which has antioxidant, immune-enhancing, cardiovascular disease-preventing, and tumor cell-inhibiting effects. Manganese sulfate can supplement manganese, participate in bone development, carbohydrate and fat metabolism, and is of great significance for maintaining the normal function of the nervous system.

[0025] The additives include 0.1-0.3 parts citric acid, 0.05-0.1 parts vitamin C, 2-4 parts fructooligosaccharides, and 0.5-1 parts β-cyclodextrin. Citric acid can adjust the pH value of the beverage, give it a refreshing sour taste, balance the sweetness, and also has antibacterial and preservative effects. Vitamin C is an antioxidant that can prevent the components in the beverage from oxidizing and deteriorating, maintain its color and nutrition, and enhance the body's immunity. Fructooligosaccharides, as prebiotics, promote the growth of beneficial bacteria in the intestines, improve intestinal function, and increase the sweetness and viscosity of the beverage. β-cyclodextrin has an inclusion effect, which can mask unpleasant odors, stabilize the beverage system, and prevent the components from settling or separating.

[0026] Another method for preparing Epimedium and Polygonatum beverage proposed in this invention includes the following steps: 1) Raw material pretreatment: Epimedium was baked at 60℃ for 2 hours and then pulverized to 20 mesh. Polygonatum was steamed at 95℃ for 1 hour and dried to 15% moisture content. This process was repeated 3 times and then cut into 0.5cm thick slices. Dioscorea opposita was peeled, steamed for 20 minutes and then cut into 1cm cubes. Trace elements were dissolved in 50℃ pure water, and β-cyclodextrin was added and stirred for 30 minutes at a speed of 150r / min. The mixture was then stored in the dark to obtain a trace element solution. 2) Synergistic extraction: Add the Epimedium, Polygonatum and Dioscorea opposita from step 1) to the dynamic extraction tank, add wolfberry and red dates, and add purified water and compound enzyme preparation to the dynamic extraction tank in sequence. Enzymatic hydrolysis is carried out at 50℃ for 2 hours. After the enzymatic hydrolysis is completed, filter with a 100-mesh filter cloth to obtain filter residue and primary filtrate. 3) Secondary extraction: Add purified water to the filter residue from step 2), extract at 85°C for 1 hour, and filter with a 100-mesh filter cloth to obtain a secondary filtrate. Mix the primary and secondary filtrates to obtain the extract. 4) Clarification treatment: Add chitosan solution to the extract in step 3), stir evenly, let stand at 25-30℃ for 4-6 hours, and filter with a plate and frame filter to obtain a clear liquid; 5) Addition of trace elements: Slowly add the trace element solution from step 1) to the clarified solution from step 4), stirring during the addition process at a speed of 100 r / min for 20 min. At the same time, nitrogen gas is introduced into the clarified solution to prevent oxidation, thus obtaining the added solution. 6) Preparation: Add white sugar, honey, citric acid, vitamin C and fructooligosaccharides to the liquid in step 5) in sequence, stir at 130-150 r / min for 15-20 min at 30℃ until completely dissolved to obtain the beverage; 7) Sterilization: The beverage from step 6) is sterilized using a combination of ultra-high temperature instantaneous sterilization (UHT) and microwave-assisted sterilization. First, it is sterilized at 120-135℃ for 3-5 seconds, then transferred to a microwave sterilization device (power 800W) for 20-30 seconds, and then rapidly cooled to 25-30℃ to obtain a sterile beverage. 8) Aseptic filling: Using aseptic filling equipment, in a Class 100 cleanroom environment, aseptic beverages are filled into sterilized PET bottles or glass bottles. After filling, the bottles are immediately capped, and the capping pressure is controlled at 0.3-0.5 MPa to obtain the finished product.

[0027] In step 2), the weight of the purified water is 5-6 times the total weight of the material inside the dynamic extraction tank. In step 2), the amount of compound enzyme preparation added is 0.2% of the volume of purified water. The compound enzyme preparation in step 2) is food-grade cellulase and pectinase, and the ratio of cellulase to pectinase is 1:1. In step 3), the weight of the purified water is 3-4 times the weight of the filter residue.

[0028] In addition, in step 4), the amount of chitosan solution is 0.15-0.2% of the extract volume, the concentration of chitosan solution is 1-2%, and it is dissolved in 0.1 mol / L acetic acid.

[0029] Example 1: An Epimedium and Polygonatum beverage, comprising the following ingredients in the indicated proportions: 5 parts Epimedium, 8 parts Polygonatum, 3 parts Lycium barbarum, 5 parts jujube, 4 parts Dioscorea opposita, 0.02 parts zinc gluconate, 0.0001 parts sodium selenite, 0.005 parts manganese sulfate, 2 parts white sugar, 1 part honey, 0.1 parts citric acid, 0.05 parts vitamin C, 2 parts fructooligosaccharides, 0.5 parts β-cyclodextrin, and purified water.

[0030] In this embodiment, the preparation method is the same as another preparation method of Epimedium and Polygonatum beverage proposed in this invention.

[0031] Example 2: An Epimedium and Polygonatum beverage, comprising the following ingredients in the indicated proportions: 7 parts Epimedium, 11 parts Polygonatum, 4.5 parts Lycium barbarum, 6.5 parts jujube, 5.5 parts Dioscorea opposita, 0.03 parts zinc gluconate, 0.0002 parts sodium selenite, 0.008 parts manganese sulfate, 4 parts white sugar, 2 parts honey, 0.2 parts citric acid, 0.07 parts vitamin C, 3 parts fructooligosaccharides, 0.7 parts β-cyclodextrin, and purified water.

[0032] In this embodiment, the preparation method is the same as another preparation method of Epimedium and Polygonatum beverage proposed in this invention. Example 3: An Epimedium and Polygonatum beverage, comprising the following ingredients in the indicated proportions: 10 parts Epimedium, 15 parts Polygonatum, 6 parts Lycium barbarum, 8 parts jujube, 7 parts Dioscorea opposita, 0.05 parts zinc gluconate, 0.0003 parts sodium selenite, 0.01 parts manganese sulfate, 5 parts white sugar, 3 parts honey, 0.3 parts citric acid, 0.1 parts vitamin C, 4 parts fructooligosaccharides, 1 part β-cyclodextrin, and purified water.

[0033] Comparison Example 1: Epimedium and Polygonatum beverages currently available on the market.

[0034] Comparative Example 2: Epimedium and Polygonatum solid tablets currently available on the market.

[0035] In this embodiment, the preparation method is the same as another preparation method of Epimedium and Polygonatum beverage proposed in this invention.

[0036] The beverages produced according to Examples 1, 2, and 3 were compared with Control Examples 1 and 2. The comparisons included the comparison of component content, the comparison of component content after 6 months and 12 months of storage, and the comparison of safety and functionality. The specific results are shown in Tables 1-5.

[0037] Table 1: Comparison of component content

[0038] By comparing the content of each component in Table 1, it can be seen that the content of icariin and polygonatum polysaccharide in Examples 1, 2 and 3 is increased compared with Control Example 1 and Control Example 2. At the same time, the beverage also contains trace elements required by the human body.

[0039] Table 2: Percentage of decrease in placements in 6 months

[0040] Table 3: Percentage of Decline in Placement over 12 Months

[0041] According to Table 2-3, after 6 months and 12 months of storage in Examples 1, 2, 3, Comparative Example 1 and Comparative Example 2, the effective contents of each element were measured. The contents in Table 1 were used as the initial contents, and the percentage decrease of each effective content was obtained by dividing the decreased content by the initial content. Sodium has relatively stable chemical properties and did not lose any contents after long-term storage. Selenium, on the other hand, will oxidize, so its loss efficiency is relatively high compared to other elements.

[0042] Compared to Examples 1, 2, and 3, the loss of each component was lower than that of Control Examples 1 and 2. This is mainly because Vitamin C and β-cyclodextrin were added in Examples 1, 2, and 3, which made their stability significantly better than that of commercial products. At the same time, according to the data comparison of Examples 1, 2, and 3, the dosage of β-cyclodextrin was positively correlated with the component retention rate. The synergistic effect between the raw materials (such as the antioxidant protection of icariin by Vitamin C) further enhanced the stability of the formulation.

[0043] Table 4: Security

[0044] According to Table 4, the total bacterial count in Examples 1, 2, and 3 is much lower than the national standard, while the bacterial count in Control Example 1 is close to the national standard limit. Control Example 2 has no bacterial count and needs to be tested for mold. It meets the national standard, but the mold content is likely to exceed the standard after absorbing moisture. There are no additive residues in Examples 1, 2, and 3, but Control Example 1 may contain preservative residues (such as sodium benzoate ≤0.1g / kg), and Control Example 2 may contain adhesive residues (such as magnesium stearate ≤0.5%).

[0045] Table 5: Functionality

[0046] According to Table 5, the icariin dissolution rate of Examples 1, 2, and 3 is relatively high, thanks to the efficient extraction of icariin, which makes the effective components of the beverage easily absorbed. In contrast, the extraction process of Control Example 1 is simple, resulting in waste of effective components. In Control Example 2, the solid needs to be dissolved in the gastrointestinal tract, resulting in slow absorption and low efficiency. The inclusion of β-cyclodextrin in Examples 1, 2, and 3 can promote absorption. The combination of fructooligosaccharides and yam polysaccharides in Examples 1, 2, and 3 can promote intestinal peristalsis. Control Example 1 has no added dietary fiber and has no intestinal conditioning effect. The dietary fiber in Control Example 2 is naturally present in the raw materials and has no additional addition, resulting in a weak intestinal conditioning effect.

[0047] Beneficial effects: 1. This Epimedium and Polygonatum beverage and its preparation method involve compounding Epimedium, Polygonatum, and trace elements such as zinc, selenium, and manganese. Zinc promotes the absorption and conversion of icariin, while selenium synergistically enhances antioxidant capacity with Polygonatum polysaccharides, solving the problem of single nutrition in traditional beverages. Furthermore, the finished product exhibits a high retention rate of icariin and a high recovery rate of trace elements. The use of β-cyclodextrin inclusion complexation technology solves the precipitation problem of trace elements and plant polyphenols, improving the stability of the beverage over long periods. The addition of yam and fructooligosaccharides not only enriches the dietary fiber content but also neutralizes the bitterness of Epimedium, improving the beverage's taste.

[0048] 2. The Epimedium and Polygonatum beverage and its preparation method utilize an enzymatic hydrolysis-constant temperature double extraction process to greatly improve the dissolution rate of epimedium glycosides. The composite sterilization process ensures the sterilization effect while avoiding the destruction of active ingredients by high temperature alone.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
