Description

Solid beverage compositions and their methods of use Technical Field

[0001] This invention belongs to the field of food, beverage or supplement technology, and specifically relates to a solid beverage composition. Background Technology

[0002] As people's living standards continue to improve, their consumption of beverages is increasing. Furthermore, people hope that existing beverages can achieve more comprehensive effects while replenishing body fluids and electrolytes.

[0003] Excessively high osmotic pressure may cause gastric retention, nausea, vomiting, and severe diarrhea in individuals with poor gastrointestinal function, as well as dehydration and electrolyte imbalances due to these side effects. Conversely, excessively low osmotic pressure may lead to low intestinal osmotic pressure, causing water to be absorbed into the intestinal wall cells, resulting in edema. Therefore, while ensuring that beverages can replenish body fluids and / or electrolytes and provide certain nutritional and health benefits, it is essential to control the beverage's osmotic range to make it suitable for a wider range of people.

[0004] Succinate can participate in the TCA cycle in the body, playing an important role in redox reactions, thereby promoting metabolism, improving athletic performance, relieving fatigue, and improving blood circulation. Lactate, as an important product and regulator in glycolysis, participates in energy metabolism and the regulation of cellular redox state during exercise, thereby improving athletic performance, promoting vasodilation, and regulating blood flow.

[0005] Furthermore, with people paying increasing attention to healthy eating, sugar-free beverages are gaining popularity. Allulose, as a novel sweetener, not only provides sweetness but also has low-calorie and blood sugar-regulating effects, as well as certain antioxidant and neuroprotective functions. Its safety has been recognized by countries including the United States, Japan, and South Korea. Allulose is a perfect substitute for sucrose. Summary of the Invention

[0071] The osmotic pressure of the solid beverage composition of the above embodiments and commercially available competing beverages was tested using the osmolarity determination method of the 2016 edition of the Chinese Standard Operating Procedures for Drug Inspection.

[0072] Sample preparation: Weigh a certain amount of sample and prepare a solution of the corresponding concentration.

[0073] Osmotic pressure determination: Take 100 μl (±10%) of the above solution and put it into the sample tube. Lift the measuring probe of the freezing point permeameter, place the sample tube on the sample needle, and make sure that no air bubbles are generated in the sample tube when adding the sample. Press the sample probe, enter the sample name, confirm and the sample will be automatically measured, and the result will be printed and recorded.

[0074] The osmotic pressure data of the solid beverage composition of this invention are shown in the table below:

[0075]

[0076] The osmotic pressure of the solid beverage compositions in Examples 2, 4, and 5 of this invention is all in the range of 280-320 mosmol / kg, with Examples 4 and 5 even reaching 290-300 mosmol / kg. The osmotic pressure of human body fluids is approximately 280-320 mosmol / L, while the osmotic pressure of commercially available competing products 1-4 is in the range of 196-271 mosmol / kg, and most of them do not achieve the ideal isotonic effect.

[0077] The solid beverage composition of this invention is isotonic, with the same osmotic pressure as the human body, and can directly replenish the loss of electrolytes in body fluids, promoting the rapid balance of water, salt, acid and alkali and osmotic pressure in the body. Example 12 Stability Test

[0078] Accelerated stability tests were conducted on Examples 2 and 4 according to the guidelines for stability testing in the Chinese Pharmacopoeia. The test results are as follows:

[0079]

[0080] The results show that all quality indicators of the formulated composition remained stable, demonstrating good stability. Example 13: Athletic Performance Test

[0081] Forty 8-week-old male ICR mice were purchased from Nanjing Wukong Biotechnology Co., Ltd. The mice were housed in an environment with four mice per cage, maintained at 23 ± 2℃ and 55 ± 5% humidity, with a 12-hour light-dark cycle, to allow them to acclimatize for one week. The mice had free access to water and food. Each group of mice was housed individually in standard cages. The experimental groups were as follows: the 40 mice were randomly divided into 5 groups (n=8) and treated for 4 weeks according to the following protocol: control group, and experimental groups (Examples 2, 4, 6, and 9), as shown in the table below:

[0082]

[0083] Forelimb grip strength test in mice: Forelimb grip strength was measured weekly using a stainless steel grid to assess muscle strength. Grip strength was measured 1 hour after drug administration. In brief, each mouse was first placed in the testing chamber for 10 minutes to acclimatize. Then, each mouse was placed on top of the grid of the grip strength meter, ensuring the mouse's forepaws were fully on the grip support. The mouse was gripped by the base of its tail, avoiding pressure on the grid. The animal was then gently pulled backward from the grid via its tail, along the axis of the grip strength measurement. The pull was slow enough to allow the mouse to resist the pull, and once the mouse released the grid, the score (gf) displayed on the grip strength measurement screen was recorded. Each animal underwent three independent trials, and the average of the three trials was calculated and recorded.

[0084] Figure 1 shows the effects of different embodiments on the forelimb strength of mice. As can be seen from the figure, after administering Examples 2, 4, 6, and 9 to mice, the forelimb grip strength of the mice was improved to varying degrees compared to the control group. Examples 2 and 4 showed significant strength increases after one week of administration, with increases of approximately 48.1% and 29.6% compared to Example 6, and approximately 42.9% and 25.0% compared to Example 9, respectively. This effect lasted for four weeks compared to the control group, and in the fourth week, Examples 2 and 4 showed an increase of approximately 32% compared to Example 6, and an increase of 37.5% compared to Example 9. It can be seen that adding succinate and lactate is more effective than adding citrate and chloride because succinate can participate in the TCA cycle in the body, promote metabolism, and play an important role in redox reactions, thereby improving athletic ability and performance; lactate, as an important product and regulator in glycolysis, participates in energy metabolism and the regulation of cellular redox state during exercise, thus improving athletic ability and performance. The solid beverage composition of this invention has a strong hydrating effect, effectively maintaining the body's water content. Its isotonic effect allows for rapid and effective electrolyte replenishment, while significantly enhancing athletic performance. Furthermore, it provides sweetness while being low in calories and sugar.

Any person skilled in the art can make various changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
