Description

Technical Field

[0001] This invention relates to the field of food and health products, specifically to food-medicine homologous compositions, their preparation methods, and fruit juice and tea beverages. Background Technology

[0002] In recent years, the sub-healthy population has expanded rapidly and is becoming increasingly younger. People are paying more and more attention to health preservation. A 2022 survey showed that exercise and diet therapy are the most common methods of health preservation. Emerging brands such as Genki Forest have also entered the functional beverage market in recent years. According to data analysis by Yingmingt, since 2017, fruit juice has shown an upward trend in RTD tea drinks, coffee, pure tea, and carbonated soft drinks, especially RTD tea drinks. This indicates that fruit juice is being paired with different beverages in a more diversified way, and related new product innovations are becoming more abundant.

[0003] Among the various fruit juices paired with different beverages, lemon juice not only has the highest proportion, but its growth rate is also particularly significant, demonstrating strong consumer preference and continued growth in market demand.

[0004] Osteoporosis (OP) is an age-related disease. The prevalence of OP among the elderly in China is 37.7%, and the prevalence gradually increases with age. Major data from the 2020 Seventh National Population Census show that my country's population aged 60 and above is approximately 264.02 million, accounting for 18.7% of the total population, an increase of 5.44 percentage points compared to 2010. With the increasingly serious problem of population aging in my country, the prevalence of OP is bound to rise. How to prevent and treat OP to avoid secondary fractures caused by it is a major and urgent problem that needs to be solved.

[0005] On May 13, 2002, the American Medical Association published a study of 497 men and 540 women over 10 years, indicating that those who drank black tea had stronger bones. The polyphenols in black tea inhibit the activity of substances that destroy bone cells. To prevent osteoporosis, it is recommended to drink a small cup of black tea daily for several years for noticeable results. Adding lemon to black tea enhances its bone-strengthening effect, and various fruits can also be added for synergistic effects. Existing technology application number 201510159680.6 discloses a clarified lemon herbal tea and its preparation method, using freshly squeezed lemon juice as the main ingredient, combined with chrysanthemum, honeysuckle, and other medicinal and edible herbs to create a beverage with certain nutritional value. However, this herbal tea uses freshly squeezed lemon juice, which contains precursors to limonene. During processing, these substances may transform into limonene over time, causing the beverage to have a bitter taste and affecting its flavor.

[0006] However, existing products still suffer from insufficient functional targeting, poor scientific formulation, and difficulty in balancing taste and efficacy. In particular, there is a lack of beverages that address the dual needs of sub-health conditioning and osteoporosis prevention, while simultaneously achieving a scientific integration of medicinal and edible substances, fruit juice, and tea. Therefore, this invention addresses these market demands and technological shortcomings by combining medicinal and edible substances with fruit juice and tea. Through scientific formulation, it maximizes functionality while satisfying consumers' pursuit of delicious taste. Summary of the Invention

[0007] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a food-medicine homology composition. This food-medicine homology composition can strengthen bones and inhibit the activity of substances that destroy bone cells, prevent osteoporosis, and can be combined with fruit juice and tea.

[0008] Another objective of this invention is to provide a method for preparing a food-medicine homology composition, which is simple to prepare, fully extracts the effective components, ensures the stability of the components, and is suitable for industrial production.

[0009] Another objective of this invention is to provide a fruit juice tea beverage that combines fruit juice with a medicinal and edible composition, achieving maximum functionality and satisfying consumers' pursuit of taste through scientific formulation.

[0010] The objective of this invention is achieved through the following technical solution:

[0011] This invention provides a food-medicine composition comprising the following components: black tea, prepared rehmannia root, cornus officinalis, wolfberry, astragalus membranaceus, eucommia ulmoides leaves, and water.

[0012] Preferably, a medicinal and edible composition comprises the following components by mass percentage: 20-50% black tea, 15-30% prepared rehmannia root, 1-10% cornus officinalis, 10-20% wolfberry, 10-20% astragalus membranaceus, 10-20% eucommia ulmoides leaf, and the balance being water.

[0013] In this invention, the black tea, prepared rehmannia root, cornus officinalis, wolfberry, astragalus, and eucommia leaves have a synergistic effect, nourishing the liver and kidneys, strengthening muscles and bones. At the same time, the combination of medicinal and edible ingredients is incorporated into consumers' daily lives in the form of tea to achieve the purpose of dietary therapy. Among them, the tea polyphenols in black tea, through antioxidant and anti-inflammatory pathways and related signaling pathways, stimulate osteoblast proliferation and differentiation, reduce osteoblast apoptosis, and promote bone mineralization; on the other hand, they inhibit osteoclast differentiation, induce osteoclast apoptosis, and reduce bone resorption, thereby restoring the balance of bone metabolism and delaying the occurrence and development of osteoporosis. Rehmannia glutinosa, with its moistening properties, nourishes the kidneys and has the effects of replenishing essence and marrow, nourishing blood and yin, making it an essential medicine for tonifying kidney yin. Modern pharmacological studies have shown that Rehmannia glutinosa promotes osteoblast formation by increasing osteoblast proliferation and alkaline phosphatase activity, as well as the expression of related genes and osteoprotegerin secretion, while inhibiting osteoclast production and reabsorption activity, thus playing an anti-osteoporosis role. Furthermore, studies have shown that Rehmannia glutinosa also has a preventive effect on osteoporotic bone loss caused by oophorectomy. Cornus officinalis, with its slightly warm and moistening properties, is warm and... It is not drying, nourishing without being harsh, and tonifies the liver and kidneys. It can benefit essence and assist yang, making it an essential medicine for balancing yin and yang. Its cornus glycosides can promote the proliferation and differentiation of osteoblasts. Goji berries can nourish the yin of the liver and kidneys, and gently replenish kidney essence and liver blood. Its rich goji polysaccharides can improve osteoporosis through multiple pathways. Astragalus is sweet and warm, and it can enter the spleen and stomach. It can replenish qi and blood, and nourish tendons and bones. Modern pharmacological studies have shown that substances such as gentianin in astragalus can significantly improve the mechanical properties and chemical composition of bones in rats, strengthen bone density, and have significant preventive and therapeutic effects on osteoporosis and osteoarthritis. Eucommia leaves have the effects of tonifying the liver and kidneys and strengthening tendons and bones. They can be used to treat kidney deficiency, lower back pain, and weakness of the legs and knees. Modern pharmacological experiments have shown that various chemical components in the water extract of Eucommia leaves, such as aucubin, geniposide, gentianin, rutin, and chlorogenic acid, can promote the proliferation, differentiation, and mineralization of osteoblasts MC3T3-E1 and inhibit apoptosis. The *Huangdi Neijing* (Yellow Emperor's Inner Classic) records that the kidneys govern the bones and are responsible for carrying the body's essence and qi. This essence and qi can transform into bone marrow, which in turn nourishes the bones, promoting bone formation, development, and regeneration. The kidneys are also the storehouse of water; if water cannot overcome fire, the bones wither and the marrow empties, the feet cannot support the body, leading to osteoporosis, or bone atrophy. Through the continuous inheritance and development by later generations of physicians, it has gradually been recognized that the location of "bone atrophy" includes the kidneys, spleen, liver, and other organs. The main causes include overwork and malnutrition, excessive salt intake, external heat pathogens, and yin pathogens damaging the kidneys. The pathogenesis involves liver and kidney deficiency, spleen and stomach weakness, and blood stasis obstructing the meridians, with kidney deficiency being the most important factor. This invention utilizes a comprehensive formula, combining traditional Chinese medicine theory with modern pharmacological effects, addressing both the symptoms and the root cause.

[0014] The present invention also provides a method for preparing a food-medicine homology composition, comprising the following steps: soaking Rehmannia glutinosa, Cornus officinalis, Lycium barbarum and Astragalus membranaceus in purified water for 25-35 minutes, bringing to a boil over high heat, then reducing to a simmer for 25-35 minutes, adding black tea and Eucommia ulmoides leaves, filtering while hot after 2-4 minutes, and obtaining the filtrate to obtain the food-medicine homology composition.

[0015] The preparation method of this invention for a food-medicine homology composition is simple. It involves soaking, boiling, and then simmering over low heat, which fully extracts the active ingredients and ensures their stability. Components such as rehmannia polysaccharides and catalpol from prepared rehmannia root, and astragalus polysaccharides and astragaloside A from astragalus root, dissolve well. Finally, adding black tea and eucommia leaves and heating for 2-4 minutes allows for rapid dissolution of tea polyphenols and caffeine from black tea, and aucubin and geniposide from eucommia leaves. This also prevents excessive destruction of heat-sensitive components in black tea and eucommia leaves, ensuring the stability of all components in the entire food-medicine homology composition.

[0016] The present invention also provides a fruit juice tea beverage comprising the following components by mass percentage: 20-40% of the medicinal and edible composition according to any one of claims 1-2, 10-20% of fruit juice, 0.08-0.2% of lemon emulsified flavoring, and the balance being water.

[0017] Preferably, the fruit juice tea beverage further includes the following components by mass percentage: 2-8% fructose syrup, 0.08-0.12% citric acid, 0.02-0.08% malic acid, 0.02-0.08% sodium citrate, and 0.02-0.04% vitamin C.

[0018] Preferably, the juice is at least one of raspberry puree, lemon juice, and mulberry puree.

[0019] Preferably, the juice is made by blending raspberry puree, lemon juice and mulberry puree in a mass ratio of 2-3:1-2:10-17.

[0020] This invention relates to a fruit juice tea beverage that combines fruit juice with a medicinal and edible homology composition. Through scientific formulation, it maximizes functionality while satisfying consumers' pursuit of taste. The fruit juice comprises raspberry puree, lemon juice, and mulberry puree. Raspberry has the effect of strengthening the kidneys and liver, and modern pharmacological studies have shown that raspberry contains various chemical components such as raspberry B, raspberry A, kaempferol, and quercetin, which have varying degrees of activity on osteocytes and osteoclasts, exhibiting a synergistic anti-osteoporosis effect. Mulberry nourishes the yin of the liver and kidneys, while also cooling the blood and reducing fever. It is often used in combination with raspberry, wolfberry, and rehmannia to treat various symptoms caused by liver and kidney yin deficiency. Modern research has confirmed that lemon juice can promote calcium absorption and increase bone density. Furthermore, the limonene in lemon juice can significantly improve cartilage damage in knee osteoarthritis. This invention combines fruit juice with a food-medicine homology composition to achieve a synergistic effect. While alleviating the bitterness of limonene, it can satisfy consumers' pursuit of a rich, natural taste and market popularity.

[0021] Preferably, the preparation method of the lemon emulsified flavoring includes the following steps: mixing 2-8g lemon oil, 0.2-0.8g Tween, 0.2-0.8g calcium lactate, 0.08-0.12g vitamin E and 12-16g xanthan gum solution, slowly adding sodium alginate solution under rapid shearing, shearing for 3-5 minutes, adding chitosan solution, and continuing to shear evenly to obtain lemon emulsified flavoring.

[0022] Preferably, the xanthan gum solution contains 0.2-0.8% xanthan gum by mass, the sodium alginate solution contains 0.8-1.2% sodium alginate by mass, and the chitosan solution contains 0.8-1.2% chitosan by mass.

[0023] Preferably, the mass ratio of sodium alginate solution to calcium lactate is 1:0.5-1:2, and the mass ratio of sodium alginate to chitosan is 5-10:1.

[0024] The lemon emulsified flavoring of this invention utilizes a composite colloidal system composed of xanthan gum, sodium alginate, and chitosan, combined with Tween-80 emulsifier to form a three-dimensional stable network, maintaining stable oil droplet size. Simultaneously, the citric acid derivatives contained in lemon oil can synergistically enhance calcium absorption efficiency with the polyphenols in black tea components of beverages.

[0025] Preferably, the preparation method of the fruit juice tea beverage includes the following steps: weighing fructose syrup, citric acid, malic acid, sodium citrate and vitamin C, adding an appropriate amount of water to dissolve, then adding the food-medicine homology composition, fruit juice and lemon emulsified flavoring, and finally adding purified water for compound blending, and after bottling and sterilization, the fruit juice tea beverage is obtained.

[0026] The beneficial effects of this invention are as follows: the food-medicine homology composition of this invention can strengthen bones and inhibit the activity of substances that destroy bone cells, thus preventing osteoporosis. It can be combined with fruit juice and tea. Furthermore, the food-medicine homology composition is simple to prepare and allows for effective extraction of active ingredients. Simultaneously, the fruit juice tea beverage of this invention uses the food-medicine homology composition as a base, adding fruit juice composed of raspberry pulp, lemon juice, and mulberry pulp, along with lemon emulsified flavoring, to achieve a synergistic effect, further strengthening bones while satisfying consumers' pursuit of a rich, natural taste and market popularity.

[0058] Comparative Example 4

[0059] The only difference between this comparative example and Example 1 is that the amount of the medicinal and edible composition added accounts for 10% of the total mass of the fruit juice tea beverage.

[0060] Comparative Example 5

[0061] The only difference between this comparative example and Example 1 is that the amount of fruit juice added accounts for 5% of the total mass of the fruit juice tea beverage.

[0062] Performance testing

[0063] First, a randomized, double-blind, controlled trial was conducted on the fruit juice tea beverages prepared in Examples 1-3 and Comparative Examples 1-5 to evaluate the intervention effect of the fruit juice tea beverages prepared in Examples 1-3 and Comparative Examples 1-5 on patients with osteoporosis.

[0064] Study Subject Screening: Eighty patients with osteoporosis were selected. Following the diagnostic criteria for osteoporosis recommended by the 1994 WHO guidelines, dual-energy X-ray absorptiometry (DXA) was used to measure the bone mineral density of the L1-L4 vertebrae in normal postmenopausal women and men over 60 years of age, and the average value was taken. A T-score < -2.5 was diagnostic of osteoporosis. Patients with hypertension, heart disease, diabetes, organic lesions, and other chronic diseases were excluded. The 80 osteoporosis patients were randomly divided into 8 groups of 10 each. A double-blind method was used, and each group consistently consumed one bottle (100ml) of the fruit juice tea beverage prepared in Examples 1-3 and Comparative Examples 1-5 of this invention daily for 3 consecutive months.

[0065] 1. Dual-energy X-ray absorptiometry (DXA) was used to periodically scan the proximal femur and lumbar vertebrae on the healthy side of 80 osteoporosis patients. The T-values ​​of bone mineral density at the femoral neck, common medulla oblongata, and L1-L4 vertebrae were measured and recorded, and the average values ​​were taken. The results are shown in Table 1.

[0066] Table 1

[0067]

[0068]

[0069] As shown in Table 1, the T values ​​of Examples 1-3 continuously increased from an initial value of approximately -2.8, reaching -2.49 to -2.53 after 3 months, approaching the osteoporosis diagnostic threshold of -2.5. Furthermore, the increase was significantly better than all comparative examples, indicating that the fruit juice tea beverage of the present invention has a definite effect on improving bone mineral density. Compared to Example 1, the T value of Comparative Example 1 only increased from -2.85 to -2.77 after 3 months, showing only slight improvement, indicating that Rehmannia glutinosa, Lycium barbarum, and Astragalus membranaceus can effectively improve osteoporosis. The T value increases in Comparative Examples 2, 4, and 5 were all much lower than in Example 1, indicating that the component ratio and dosage of the fruit juice tea beverage of the present invention are key parameters for ensuring efficacy. Comparative Example 3, which used only apple juice instead of fruit juice, showed a weaker T value improvement effect than Example 1, indicating that fruit juice can synergistically enhance the effect on improving bone mineral density when combined with the medicinal and edible ingredients.

[0070] The T-values ​​of all embodiments and some comparative examples showed a pattern of "small improvement after 1 week, significant improvement after 1 month, and optimal effect after 3 months," indicating that the beverage needs to be consumed continuously for about 3 months to achieve the ideal intervention effect. That is, the longer the intervention time of the fruit juice tea beverage prepared by this invention, the more significant the improvement effect.

[0071] 2. Periodically draw 10 ml of venous blood from the study subjects' elbows, and use an immunoluminescence analyzer to measure serum type I procollagen N-terminal propeptide (P1NP) and osteocalcin (OC). The results are shown in Table 2.

[0072] Table 2

[0073]

[0074]

[0075] As shown in Table 2, the fruit juice tea beverage of this invention can effectively reduce P1NP levels; however, its effect on OC is not significant. Combined with Table 1, the decrease in P1NP and the increase in T value in this embodiment are synchronized, proving that the beverage ultimately improves bone density by regulating bone metabolism.

[0076] Second, the particle size distribution of the lemon emulsified flavoring prepared in Example 1 was analyzed by dynamic light scattering (DLS), and the results are as follows: Figure 1 As shown, by Figure 1 It can be seen that the average particle size of the lemon emulsified flavoring prepared in Example 1 is about 1041 nm, with good dispersibility and the particle size distribution is mainly concentrated in a single range, and the experimental data is reliable.

[0077] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
