Description

Technical Field

[0001] This invention belongs to the field of sports nutrition foods, specifically relating to an endurance sports nutrition food that helps relieve physical fatigue. Background Technology

[0002] In daily training, the ultimate goal of pursuing higher, faster, and stronger athletic goals, or the targeted improvement of specific physical qualities for a particular sport, is to achieve better athletic performance. Promoting athletes' physical recovery as quickly as possible, enhancing their athletic ability, and improving training effectiveness are major issues for those working in the sports nutrition industry.

[0003] β-Alanine is a precursor to carnosine synthesis. Supplementing with β-alanine can significantly increase the carnosine content in muscles. Carnosine is the main active ingredient in the body, and increased carnosine levels in muscles can alleviate fatigue in competitive athletes. Caffeine has a similar structure to adenosine, a metabolite of adenosine triphosphate (ATP), and can competitively bind to receptors that induce fatigue and sleep signals, thus exerting its biological activity of promoting wakefulness and alleviating fatigue. Numerous interventional, observational, and clinical studies on healthy subjects, both domestically and internationally, have shown that moderate consumption of caffeinated beverages exhibits various benefits in improving alertness and attention, promoting endurance and strength, enhancing athletic performance, alleviating mental and physical fatigue, accelerating fat metabolism, and providing antioxidant effects. Ginseng can regulate multiple core genes, thereby modulating a series of signaling pathways such as TNF and IL-17, thus exerting an anti-fatigue effect. Polygonatum polysaccharide (PCP1), an extract of Polygonatum sibiricum, increases the reserves of energy substances (liver glycogen, muscle glycogen, ATP) in mice by regulating the uptake and metabolism of sugars and lipids, reducing the accumulation of metabolites (lactic acid, urea nitrogen), and decreasing the damage of metabolites to cells and organs. It also reduces MDA content, increases the enzyme activity of SOD and GSH-Px, inhibits oxidation processes, and alleviates fatigue caused by oxidative stress. Lycium barbarum polysaccharide, a major extract of Lycium barbarum, can increase muscle glycogen reserves and improve the phagocytic function of phagocytes, thereby enhancing the anti-hypoxia ability of mice. Zinc plays an important role in the normal function and anti-fatigue ability of skeletal muscle; magnesium supplementation can improve muscle metabolism and work efficiency; chromium's biological function is mainly manifested in its close relationship with insulin, and their combined effect can regulate glucose energy supply.

[0004] Currently, there are numerous sports nutrition products on the market that can alleviate physical fatigue, but these products lack further experimental verification of their efficacy in relieving physical fatigue. Moreover, high-β-alanine products on the market suffer from serious problems of deliquescence and clumping during their shelf life, and have antagonistic effects with other vitamins and minerals, which seriously affects the user experience.

[0005] This product, formulated using bottom spray coating technology and square cone hopper mixing technology, effectively solves the problems of β-alanine's hygroscopicity, oxidation, clumping, and antagonistic effects with other vitamins and minerals. Animal experiments have shown that it can alleviate physical fatigue in mice, providing important technical support for the vigorous development of sports and the health industry. Summary of the Invention

[0006] A sports nutrition composition for endurance that helps relieve physical fatigue, the composition comprising the following components: highly branched cyclodextrin, coated β-alanine crystal particles, compound medicinal and edible powders (ginseng, amla, wolfberry), beetroot powder, watermelon powder, compound vitamins (thiamine hydrochloride, riboflavin, pyridoxine hydrochloride, cyanocobalamin, niacin, folic acid, biotin, caffeine), compound minerals (magnesium gluconate, zinc gluconate, chromium chloride), and apple polyphenols;

[0007] Preferably, the raw materials of the composition, by weight, include the following components: 300-500g of highly branched cyclodextrin, 300-500g of coated β-alanine crystals, 350-550g of compound medicinal and edible powder, 150-200g of beetroot powder, 200-350g of watermelon powder, 10-30g of compound vitamins, 40-70g of compound minerals, and 30-50g of apple polyphenols.

[0008] Preferably, the compound medicinal and edible powder is prepared by compounding three medicinal and edible extracts in a certain mass ratio, with the following per kilogram addition: 80-130g ginseng extract, 40-65g Polygonatum extract, and 25-45g Lycium barbarum extract. Ginseng can regulate multiple core genes, thereby regulating a series of signaling pathways such as TNF and IL-17, thus exerting an anti-fatigue effect. Polygonatum polysaccharide (PCP1), an extract of Polygonatum, increases the reserves of energy substances (liver glycogen, muscle glycogen, ATP) in mice by regulating the uptake and metabolism of sugars and lipids, reducing the accumulation of metabolites (lactic acid, urea nitrogen), reducing the damage of metabolites to cells and organs, and simultaneously reducing the content of MDA, increasing the enzyme activity of SOD and GSH-Px, inhibiting the oxidation process, and alleviating fatigue caused by oxidative stress. Lycium barbarum polysaccharide is a major extract of Lycium barbarum, which can increase muscle glycogen reserves and improve the phagocytic function of phagocytes, thereby enhancing the anti-hypoxia ability of mice.

[0009] Preferably, the amount of compound minerals added per kilogram is: 200-500g magnesium gluconate, 3-8g zinc gluconate, and 0.2-0.5g chromium chloride. Zinc plays an important role in the normal function and anti-fatigue ability of skeletal muscle, magnesium supplementation can improve muscle metabolism and work efficiency, and the biological function of chromium is mainly manifested in its close relationship with insulin. Their combined effect can adjust the glucose energy supply status.

[0010] Preferably, the amount of compound vitamins added per kilogram is as follows: caffeine 0.01-1g, thiamine hydrochloride 0.02-0.03g, riboflavin 0.02-0.03g, pyridoxine hydrochloride 0.02-0.03g, cyanocobalamin 0.00004-0.00005g, niacin 0.1-0.15g, folic acid 0.001-0.002g, and biotin 0.0001-0.0003g.

[0011] The principle of the bottom-spray fluidized bed coating technology is as follows: Dry powders of drugs and excipients rise from the product collection chamber to the upper boiling expansion chamber under the action of a lower hot air flow. After mixing for a period of time, the spray nozzles in the boiling chamber begin to spray a binder solution counterclockwise. The powder that has absorbed the solution begins to agglomerate into small particles. As the binder is continuously added, the small particles slowly aggregate and form microspheres during the continuous "boiling" process. Due to the larger volume and density of the microspheres, they settle at the bottom of the small particles and powder. Therefore, the powder and small particles that have not yet formed into pellets have more opportunities to absorb the binder and aggregate until they are all pelletized. After stopping the spraying of the binder, the hot air flow rate and temperature are appropriately increased for fluidized drying. The bottom-spray device installs nozzles at the center of a distribution plate, allowing the material to circulate in an orderly manner. The atomized droplets enter the bed in the same direction as the fluidizing gas and come into close contact with the material, reducing atomized liquid loss and improving coating efficiency and quality. This effectively solves problems associated with β-alanine, such as its hygroscopicity, oxidation, agglomeration, and antagonistic effects with other vitamins and minerals. The preparation method employed involves bottom-spray fluidized bed coating technology, selecting fillers and coating materials in specific proportions and according to equipment parameters. The steps include the following:

[0012] (a) Wet granulation: β-alanine crystals are mixed with a filler, and a binder solution (e.g., water) is added to obtain a wet material. The mixing ratio of β-alanine crystal particles to filler ranges from 99:1 to 30:70 (weight to weight or volume to volume); and / or the ratio of the filler to the binder solution is from 1:1 to 1:1.5 (weight to weight or volume to volume). The stirring motor of the wet granulator rotates at a speed of 10–200 r / min, the shear head speed is 50–600 r / min, and / or the feed rate is 5–15 r / min.

[0013] (b) Extrusion: The wet material is extruded through an extruder to obtain strips of material with the same diameter. The screen aperture of the extruder is 0.25-0.85 mm, and the screw speed of the extruder is 100-300 r / min.

[0014] (c) Rounding: The obtained strip-shaped material is rounded at high speed by a rounding device to obtain small particles with the same size and the required roundness; the rotation speed of the rounding device is 400-1200 r / min, and / or the rounding time is 15s-10min.

[0015] (d) Coating: The air inlet velocity of the Wurster coating machine is 15-30 Hz, the coating temperature is 20-50 ℃, the feed rate of the coating liquid is 1-20 r / min, and / or the coating weight increases by 0.1%-80%; after coating, the material is dried for 15-25 min, and the moisture content of the final material is controlled to be less than 3.0%, thus obtaining coated β-alanine crystal particles.

[0016] The mixing equipment used is an IBC mixer, which utilizes mechanical force and gravity to uniformly mix two or more materials. This mixing method is widely used in various industrial production processes and daily life. Its parameters include: a loading coefficient of 30%–80% and a working speed of 3–15 r·min⁻¹. The mixed powder is then quantitatively filled and heat-sealed using a fully automatic drum food canning machine, controlling the filling amount to 150±1.5g / drum with a quantitative filling accuracy of over 99.9%, resulting in an endurance sports nutrition food that helps alleviate physical fatigue.
