Description

Technical Field

[0001] This application relates to the field of compound health food technology, and more specifically, it relates to a sleep aid food based on a compound formula of jujube seed, its preparation method and application. Background Technology

[0002] With the fast pace of modern life, people with high-intensity jobs generally suffer from physical exhaustion. After working for a long time, these people consume a lot of energy, often manifesting as muscle fatigue and lack of energy. They need to replenish energy quickly to promote recovery, but many people have difficulty getting high-quality sleep, which leads to the accumulation of fatigue the next day, forming a vicious cycle.

[0003] There have been many reports on sports nutrition foods—energy supplements—such as energy gels and energy powders. Their formulation design is relatively simple, mainly using rapidly absorbed carbohydrates such as maltodextrin, glucose, and fructose as core ingredients, combined with a small amount of vitamins or minerals. The aim is to quickly raise blood sugar levels and replenish muscle glycogen reserves after exercise or during work breaks. They do achieve the expected results in replenishing energy and have been widely recognized by the sports nutrition community.

[0004] However, existing energy supplements have a significant functional deficiency: they generally only focus on "energy input" and completely ignore the neuronal excitation-inhibition imbalance that accompanies energy consumption. Carbohydrates that provide rapid energy may further exacerbate blood sugar fluctuations, thereby affecting sleep. Therefore, it is necessary to develop a special dietary food that can safely and effectively relieve neuronal excitation and promote sleep while supplementing energy. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides a sleep aid food based on a compound formula of jujube seed and its preparation method, which can achieve the dual effects of rapid energy replenishment and regulation of physical and mental state.

[0006] In the first aspect, this application provides a sleep aid food based on a compound formula of jujube seed, employing the following technical solution:

[0007] A sleep aid food based on a compound formula of jujube seed, comprising the following components by weight percentage: 20-30% jujube seed, 8-15% longan pulp, 5-10% polygonatum, 5-10% lily bulb, 8-12% jujube, 1-3% γ-aminobutyric acid, and the balance being maltodextrin.

[0008] Further preferred, the product consists of the following components by weight percentage: 25% jujube seed, 12% longan pulp, 8% polygonatum, 8% lily bulb, 10% jujube, 2% γ-aminobutyric acid, and the balance being maltodextrin.

[0009] More preferably, the jujube seed, longan pulp, polygonatum, lily bulb, and jujube are all powders that have been dried at low temperature and then pulverized and sieved, with a fineness of 80-100 mesh.

[0010] More preferably, the dosage form of the sleep aid food is a solid beverage, powder, or granules.

[0011] By adopting the above technical solution, the traditional Chinese medicine theory of "principal, assistant, adjuvant, and guide" effectively achieves synergistic promotion of functions. It can replenish energy while safely and effectively relieving nerve excitation and promoting sleep, exhibiting the unique effect of "nourishing without overstimulating, and calming without stagnation." A detailed analysis follows:

[0012] Maltodextrin, as the principal ingredient, can play the role of providing rapid energy by directly providing the body with easily absorbed carbohydrates, thus solving the core problem of insufficient energy.

[0013] Sour jujube seed, as an assistant ingredient, primarily calms the mind and soothes the nerves. It is a key food and medicinal ingredient for improving sleep quality, assisting the principal ingredient in replenishing energy while stabilizing the nervous system.

[0014] Longan pulp, Solomon's seal, and jujube are all used as adjuvants: the three work together to invigorate qi and nourish blood, tonify the heart and spleen, assist the principal and assistant herbs in strengthening the body, relieve fatigue, and prevent the superficial excitement caused by simply providing energy;

[0015] Lily and γ-aminobutyric acid (GABA) are used as guiding agents: lily calms the mind and soothes the nerves, while GABA directly inhibits neurotransmitters. Together, they guide other drugs to the affected area and synergistically enhance the soothing and sleep-aiding effects.

[0016] Secondly, this application provides a method for preparing a sleep-aiding food based on a compound formula of jujube seed, comprising the following steps:

[0017] S1. Raw material pretreatment: Select raw materials that meet food-grade standards. After removing impurities, wash the jujube seeds, longan pulp, polygonatum, lily bulbs, and jujubes with clean water, put them in a drying oven and dry them at a low temperature until the moisture content is ≤8%. Cool them to room temperature and set aside for later use.

[0018] S2. Grinding and sieving: Grind the jujube kernel, longan pulp, polygonatum, lily bulb and jujube that have been pretreated and cooled in S1 to 80-100 mesh, and then sieve them separately with γ-aminobutyric acid and maltodextrin to remove coarse particles that are not thoroughly ground, and obtain powder of each raw material for later use.

[0019] S3. Sterilization: Sterilize each raw material powder in S2 with ultraviolet light, and cool to room temperature after sterilization for later use.

[0020] S4. Mixing: According to the proportions of each raw material, mix the sterilized maltodextrin, jujube seed powder, longan pulp powder, jujube powder, polygonatum powder, lily powder, and γ-aminobutyric acid to obtain a mixed powder.

[0021] S5. Packaging: The mixed powder obtained in S4 is packaged and sealed to obtain the finished product.

[0022] More preferably, the low-temperature drying temperature in S1 is 50-60°C.

[0023] More preferably, the ultraviolet sterilization time in S3 is 30-40 minutes;

[0024] The mixing conditions in S4 are: rotation speed of 200-300 r / min and mixing time of 15-20 min.

[0025] Thirdly, this application provides a sleep aid food based on a compound formula of jujube seed, or the application of the product obtained by the above method in the preparation of a special diet, wherein the special diet can replenish energy while safely and effectively relieving nerve excitation and promoting sleep.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. This application applies the theory of "principal, assistant, adjuvant, and guide" in traditional Chinese medicine to the formulation design of energy-supplementing sports nutrition foods. Maltodextrin is used as the principal ingredient to provide rapid energy, jujube seed is used as the assistant ingredient to calm the mind and soothe the nerves, longan pulp, polygonatum, and jujube are used as adjuvant ingredients to invigorate qi and nourish blood, and lily bulb and γ-aminobutyric acid are used as guide ingredients to clear the mind and promote sleep. This achieves a synergistic effect of energy supplementation and physical and mental relaxation, and solves the technical problem of the single function of existing products.

[0028] 2. The efficacy of this application depends on the combination of each component. Only under the specific combination of the "principal, assistant, adjuvant, and guide" components can the optimal dual efficacy be obtained. The absence or replacement of any component will lead to a significant decrease in the key effects. Moreover, the raw materials are both medicinal and edible, safe and reliable, and suitable for a wider range of people.

[0029] 3. The product of this application has been verified by animal experiments to effectively reduce the number of spontaneous activities and shorten the sleep latency. Compared with the commercially available control group and the missing / replacement control group, its performance is particularly outstanding. Moreover, the preparation method is simple and easy to implement, which is convenient for industrial or household short-term production. Detailed Implementation

[0046] Table 3: Formulation composition of Comparative Examples 1-6

[0047]

[0048] Performance testing

[0049] The food products obtained in each embodiment and comparative example were selected as test subjects, and then mouse animal experiments were conducted. The specific test methods and conditions are as follows:

[0050] 1. Experimental Materials and Group Management Methods

[0051] Experimental animals: SPF-grade Kunming mice, weighing 20±2g, half male and half female, a total of 260 mice (20 mice per group), were acclimatized for 3 days before the experiment began.

[0052] Grouping and administration: The subjects were divided into a blank control group (physiological saline), Example 1-6 groups, and Comparative Example 1-6 groups. The gavage dose was 0.2 mL / 10 g body weight (the Example and Comparative Example groups were prepared with a solution of 0.1 g sample / 10 g body weight, i.e., high dose), once a day for 14 consecutive days.

[0053] 2. Animal experiments

[0054] 1) Energy replenishment effect test: After fasting for 12 hours on the 14th day, the mice were placed in a swimming box with a lead weight of 5% of their body weight on their tails and the water was 30cm deep and the water temperature was 25±1℃. The time from the start of swimming to exhaustion (head submerged in water for 10 seconds without surfacing) was recorded.

[0055] 2) Test of physical and mental relaxation effect:

[0056] 2.1 Spontaneous Activity Experiment: After fasting for 12 hours on day 14, mice were placed in a spontaneous activity recorder and allowed to adapt for 5 minutes. The number of spontaneous activities (horizontal + vertical) within 10 minutes was recorded.

[0057] 2.2 Sleep latency detection: After the spontaneous activity test, sodium pentobarbital (50 mg / kg) was injected intraperitoneally, and the time from injection to the disappearance of the righting reflex was recorded.

[0058] The results are expressed as mean ± standard deviation. The t-test was used for comparisons between groups. P < 0.05 was considered statistically significant, and P < 0.01 was considered highly statistically significant. The relevant test results are recorded in Table 4.

[0059] Table 4: Performance test results of Examples 1-6 and Comparative Examples 1-6

[0060]

[0061] As can be seen from the data in Examples 1-6 of Table 4, the sleep-aiding foods based on the jujube seed compound formula obtained in Examples 1-6 of this application have all achieved significant dual effects of energy replenishment and physical and mental relaxation in animal experiments. The specific analysis is as follows:

[0062] The exhaustive swimming time in Examples 1-6 was as long as 34.8-41.5 min, which was 91.2-128.0% higher than that of the blank control group (18.2 min).

[0063] The number of spontaneous activities within 10 minutes was as low as 105-132 times, compared to 186 times in the blank control group, a reduction of 29.0-43.5%;

[0064] Its sleep latency was shortened to 3.8-5.6 min, compared with 8.6 min in the blank control group, the reduction was 34.9-55.8%. Moreover, Example 1, as the best example, had an exhaustion swimming time of 41.5 min, 105 spontaneous activities, and a sleep latency of 3.8 min, all of which were significantly better than Examples 2-6.

[0065] A comparison of Examples 1 and 2-3 shows that the preferred sleep aid food is composed of 20-30% jujube seed, 8-15% longan pulp, 5-10% polygonatum, 5-10% lily bulb, 8-12% jujube, 1-3% γ-aminobutyric acid, and the balance maltodextrin. Products with excellent performance can be obtained within this range.

[0066] A comparison of Example 1 with Examples 4-5 shows that, after slight adjustments to the preparation process parameters, its performance is basically equivalent to that of Example 1 (41.5 min, 105 times, 3.8 min), indicating that the preparation process of this application has a wide window and good stability.

[0067] As for the process parameters of Example 6 deviating from the preferred range (drying temperature 70°C, UV sterilization for 20 min, mixing speed 500 r / min, mixing time 5 min), the high-temperature drying may destroy some heat-sensitive active ingredients (such as γ-aminobutyric acid and jujube seed saponins) or affect the dispersion effect. However, the overall performance is still significantly better than each comparative example, which further confirms the robustness of the formulation of this application.

[0068] Furthermore, by comparing Examples 1-6 one by one with Comparative Examples 1-6, the following conclusions can be drawn:

[0069] 1) Comparative Example 1 was the pure maltodextrin group, whose exhaustion swimming time was 42.5 min, which was not significantly different from Example 1 (41.5 min) (P>0.05), and the improvement was only 2.4%;

[0070] However, the number of spontaneous activities was as high as 180, and the sleep latency was as long as 8.5 minutes, which was almost identical to the blank control group (186 times, 8.6 minutes).

[0071] It is evident that maltodextrin, as a rapidly absorbed carbohydrate, can quickly raise blood sugar levels and replenish muscle glycogen, thereby significantly prolonging the time spent swimming to exhaustion. This is the core manifestation of its role as the "principal drug" for rapid energy supply. However, pure maltodextrin has no neuroregulatory function whatsoever, cannot alleviate the state of nerve excitation caused by fatigue, and cannot shorten the sleep latency.

[0072] Data from Comparative Example 1 showed that the increase in exhaustive swimming time (+133.5% compared to the control group) was essentially the same as in Example 1 (+128.0% compared to the control group), but the number of spontaneous activities decreased by only 3.2% (compared to the control group), and sleep latency shortened by only 1.2% (compared to the control group). In contrast, Example 1 showed a 43.5% decrease in the number of spontaneous activities and a 55.8% shortening in sleep latency.

[0073] 2) In Comparative Example 2, due to the absence of the herb Ziziphus jujuba var. spinosa, the exhaustion swimming time was 42.0 min, which was not significantly different from Example 1 (41.5 min) (P>0.05), with a relative deviation of only +1.2%; however, the number of spontaneous activities was as high as 162, and the sleep latency was as long as 7.2 min. Compared with Example 1 (105 times, 3.8 min), the number of spontaneous activities increased by 54.3%, and the sleep latency was prolonged by 89.5%.

[0074] The specific reasons are as follows: The flavonoid components in jujube seed, such as jujube seed saponin A, jujube seed saponin B, and spinosin, have been confirmed by pharmacological studies to exert a definite sedative-hypnotic effect by acting on GABA-A receptors, 5-HT1A receptors and adenosine A1 receptors. Its core mechanism is "drawing yang into yin", which causes the central nervous system, which is over-excited due to fatigue, to enter an inhibitory state.

[0075] In Comparative Example 2, although maltodextrin provided sufficient energy and γ-aminobutyric acid also had a certain direct inhibitory effect, the lack of jujube seed as a "mind-regulating" ingredient meant that the entire formula lacked the key component to regulate the "mind" from the root. Therefore, after the mice were given energy, the excitability of their nervous system remained at a high level, as evidenced by a persistently high number of spontaneous activities and a significantly prolonged sleep onset time of 7.2 minutes, which was only 16.3% shorter than that of the blank control group.

[0076] The above results indicate that although γ-aminobutyric acid (GABA) has a sleep-inducing effect as a "guide drug," its effect is limited when it exists alone. As can be seen from the comparison between Comparative Example 2 and Comparative Example 3, the soothing effect is further reduced after the absence of GABA, and it must rely on the core "calming and tranquilizing" effect provided by jujube seed as a basis.

[0077] 3) In Comparative Example 3, due to the absence of the drug γ-aminobutyric acid, the exhaustion swimming time was 40.8 min, which decreased by 1.7% compared with 41.5 min in Example 1 (P>0.05); the number of spontaneous activities was 148, which increased by 41.0% compared with 105 in Example 1; and the sleep latency was 6.5 min, which was extended by 71.1% compared with 3.8 min in Example 1. It can be seen that γ-aminobutyric acid also has the effect of inducing sleep.

[0078] 4) Due to the lack of adjuvant, the exhaustion swimming time of Comparative Example 4 decreased sharply to 32.5 min, the number of spontaneous activities was as high as 170, and the sleep latency was as long as 7.8 min. It is particularly noteworthy that the amount of maltodextrin in Comparative Example 4 was as high as 65%, that is, the absolute content of energy supplement raw materials was almost doubled, but its exhaustion swimming time was significantly shorter than that of Example 1.

[0079] The specific reasons are as follows: Longan pulp, Solomon's seal, and jujube, the three auxiliary herbs, play the role of "tonifying qi and blood, and nourishing the heart and spleen" in the theory of traditional Chinese medicine. From the perspective of modern medicine, long-term physical exertion and mental stress will lead to the body being in a state of "deficiency of both qi and blood", which is manifested as depletion of energy metabolism substrates, decline in mitochondrial function, reduction in neurotransmitter synthesis, and endocrine disorders.

[0080] Longan pulp is rich in glucose, various vitamins and iron, which can directly replenish energy and improve anemia; Polygonatum polysaccharides in Polygonatum have antioxidant, mitochondrial protective and immune-regulating functions; cyclic adenosine monophosphate and various organic acids in jujube can promote energy metabolism and improve gastrointestinal absorption.

[0081] The synergy of these three factors provides the body with an internal environment of "abundant Qi and blood," enabling more efficient utilization and conversion of the rapid energy supply from maltodextrin. It also provides a material basis for the calming effects of jujube seed and GABA.

[0082] Therefore, in the absence of adjuvant drugs, even with a significant increase in the dosage of maltodextrin, mice lacked the foundation for "strengthening" their immune system and had low energy metabolism efficiency. Maltodextrin may have been converted into fat for storage rather than used to improve exercise endurance. At the same time, the supply of amino acid precursors and cofactors required for neurotransmitter synthesis was insufficient, which prevented jujube seed and GABA from fully exerting their sedative effects.

[0083] 5) In Comparative Example 5, after replacing γ-aminobutyric acid with an equal amount of glycine, the exhaustion swimming time was 38.5 min, which was 7.2% lower than that in Example 1; the number of spontaneous activities was 140, which was 33.3% higher than that in Example 1; and the sleep latency was 6.0 min, which was 57.9% longer than that in Example 1.

[0084] Comparative analysis of the two shows that glycine does indeed have a certain inhibitory effect on nerves, but its effect is still significantly worse than that of the GABA group in Example 1 (105 out of 140 comparisons, 3.8 min out of 6.0 min). The specific reasons are as follows:

[0085] The main mechanism of action of γ-aminobutyric acid (GABA) is to directly bind to GABA_A receptors on the postsynaptic membrane, promote the opening of chloride ion channels, and cause hyperpolarization of the postsynaptic membrane, thereby rapidly and efficiently reducing neuronal excitability. Although glycine is also an inhibitory amino acid, its receptors are mainly distributed in lower centers such as the spinal cord, brainstem, and retina.

[0086] Furthermore, the target mechanisms of the jujube seed and lily bulb components in this application's formulation are closely related to the GABAergic system—jujube seed saponins can enhance the function of GABA_A receptors, and steroidal saponins in lily bulbs also have similar GABAergic regulatory effects. Only when GABA acts as a "guide drug" can it form a "target synergy" with the aforementioned components, guiding the drugs to concentrate their effects on the GABAergic system and achieving the shortest sleep latency. Glycine, due to its different mechanism of action, cannot achieve the same synergistic effect.

[0087] 6) The formula ratio of Example 6 was further adjusted, specifically: the amount of jujube seed was significantly increased from 25g to 45g, an increase of 80%, while the amount of longan pulp was reduced from 12g to 5g, a decrease of 58.3%. The test results were as follows: the exhaustion swimming time was 38.8 min, a decrease of 6.5% compared to Example 1; the number of spontaneous activities was 92, a further decrease of 12.4% compared to Example 1; and the sleep latency was 3.5 min, a further shortening of 7.9% compared to Example 1.

[0088] Based solely on the data, the soothing effect of Comparative Example 6 appears to be "stronger." However, during the experiment, the applicant found that after 14 consecutive days of gavage, mice in Comparative Example 6 exhibited significant adverse reactions such as lethargy, decreased appetite, sluggishness, and ruffled fur. Some mice showed signs of excessive central nervous system inhibition, such as reduced activity and curling up motionless. This phenomenon was not observed in the Example group or other Comparative Example groups. The reason for this is that excessive use of jujube seed can lead to excessive inhibition of the central nervous system, producing side effects similar to "drowsiness, weakness, and lethargy."

[0089] In summary, it can be concluded that this application achieves a synergistic effect of energy replenishment and physical and mental relaxation through the compounding of all components in the "principal, assistant, adjuvant, and guide" formula. Each component is indispensable under specific ratios, and the absence or replacement of any component will lead to a significant decrease in key efficacy indicators.

[0090] This specific preparation example is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this preparation example without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
