Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to a postbiotic casein hydrolyzed peptide solid beverage for improving sleep quality. Background Art

[0002] Sleep disorders are extremely harmful to the human body. In mild cases, it can cause a loss of concentration and have a negative impact on work and study. In severe cases, it can affect the normal functioning of the brain and the body's immune defense capabilities. Even every high-risk major disease is inseparable from the lack of sleep. The sudden death rate caused by sleep problems is much higher than that of people with normal sleep. According to surveys and studies, the main causes of sleep disorders are neurotransmitter disorders (decreased function of γ-aminobutyric acid receptors, imbalance in 5-HT circadian secretion), changes in hormone levels, abnormal cortisol rhythm, chronic stress, anxiety and depression, circadian rhythm reversal and hidden diseases. Research by Matthew Walker, director of the Center for Human Sleep Science at the University of California, Berkeley, shows that long-term lack of sleep can induce a variety of diseases, such as hypertension, diabetes, depression, obesity, cardiovascular and cerebrovascular diseases, and other diseases. Therefore, it is urgent to improve sleep quality. At present, the drugs used to treat insomnia are mainly Western medicine and Chinese medicine. Western medicine is often accompanied by unclear effects, long-term medication, high drug dependence, and large side effects. Long-term use may cause harm to the kidneys or liver. Traditional Chinese medicine sleep aid products are expensive and often have poor palatability. Therefore, developing functional foods that can be consumed daily and for a long time is more in line with the needs of modern society to fight against anxiety caused by high stress and improve sleep quality.

[0003] For example, CN115226773A discloses a composite probiotic sleep-aiding solid beverage and a preparation method, which contains 20.03-60.03 parts of whole milk powder, 1-2 parts of tea theanine, 4-5 parts of γ-aminobutyric acid, 0.20 parts of vitamin C, 2-5 parts of composite probiotics, 16.02-36.02 parts of inulin, 5.01-15.01 parts of oligofructose, 7.01-17.01 parts of erythritol (sweetener), thickener and flavor. Among them, γ-aminobutyric acid, tea theanine and whole milk powder are all amino acids or protein components, inulin and oligofructose are prebiotics, so the effective ingredients of the scheme are actually only amino acids, probiotics and prebiotics, and the types of effective ingredients are relatively single, and it is difficult to comprehensively and comprehensively affect and regulate the various factors that cause sleep disorders, so the scheme has limited effect on improving sleep quality. In addition, the product contains a high amount of whole milk powder, which is not suitable for people who are intolerant to dairy products or those who pursue low-calorie, low-fat intake. The formula is extremely thin in terms of taste, using only erythritol sweetener, the taste is not rich enough, which is not conducive to market promotion, and the sensory experience needs to be further optimized.

[0004] In view of the above problems, the present invention hopes to propose an improved solution. Summary of the invention

[0028] The present invention constructs a scientific sleep-aiding system through the coordination of neurotransmitter regulation, gut-brain axis optimization, herbal multi-target intervention and sensory enhancement quadruple pathways, and adds γ-aminobutyric acid, casein hydrolyzed peptides, walnut peptides, jujube seeds, Poria powder, lily powder, lotus seed powder, oligofructose, oligogalactose, resistant dextrin, postbiotics, double rose fruit powder, and sour cherry powder to the solid beverage, which includes both inhibitory neurotransmitters and amino acids and bioactive ingredients such as jujube seed saponins and proanthocyanidin B-2 that promote the release of inhibitory neurotransmitters, promote intestinal flora to utilize prebiotics and postbiotics, degrade prebiotics or postbiotics into short-chain fatty acids, and enable the gut-brain axis to play a role in supporting sleep; add rose fruit powder, etc., provide sleep-aiding aromatic substances, which are used to cheer up, regulate emotions, relieve anxiety and depression, etc., thereby comprehensively and collaboratively exerting the sleep-aiding effect. The experiment of the present invention also proves that the solid beverage has a good sleep-aiding effect through the Pitsonburg Sleep Index Scale survey.

[0029] Neurotransmitter regulator: Gamma-aminobutyric acid plays a direct role in regulating neurotransmitters, directly activating GABA-A receptors, inhibiting excessive neuronal discharge, and reducing the proportion of EEG beta waves (awakening waves). Phosphatidylserine PS is used to enhance brain cell membrane fluidity, promote acetylcholine synthesis (enhance memory-related theta wave activity), and indirectly relieve anxiety-related insomnia. Walnut peptides contain antioxidant peptides (such as Walnut peptide-3), which inhibit microglial inflammatory factors (such as TNF-α, etc.) and protect neurons from oxidative damage.

[0030] Gut-brain axis regulators: Postbiotics are inactivated bacterial metabolites (such as lipoteichoic acid), which can activate TLR2 receptors, promote IL-10 secretion (anti-inflammatory factor), and reduce intestinal sleep disturbances. Casein hydrolyzed peptides can release β-casomorphin-7, inhibit the upload of intestinal pain signals through μ-opioid receptors, and reduce the frequency of night awakenings. Fructooligosaccharides and galacto-oligosaccharides increase the proliferation rate of bifidobacteria in the intestine, improve the efficiency of tryptophan conversion to 5-HT, promote melatonin synthesis, and play a sleep-inducing effect. Resistant dextrin can be slowly fermented in the intestine to produce butyric acid (colon concentration ≥20mM), activate vagus nerve afferent fibers, and enhance NREM sleep duration.

[0031] Multi-target synergist of medicinal and edible herbs: Jujube saponin A contained in jujube seed powder inhibits hypothalamic CRH release, reduces serum cortisol levels (decreases at night), and shortens sleep latency. Poria polysaccharide (PCP-2) regulates Th1 / Th2 balance and reduces IL-6-mediated inflammatory sleep disruption. Lilium saponin and liensinine synergistically activate 5-HT1A receptors and improve sleep maintenance stability (reduce the number of awakenings).

[0032] Flavor and metabolic regulator: Linalool in double rose fruit powder activates the parasympathetic nerves through the olfactory receptor OR2J3, reducing the heart rate variability (HRV) LF / HF ratio. Sour cherry powder is rich in natural melatonin precursors (0.2μg / g), which can accurately match the human body's secretion rhythm and increase the peak concentration of salivary melatonin. Polydextrose has water retention (4g water / g), which can prolong gastric emptying time and prevent blood sugar fluctuations from interfering with sleep.

[0033] Among them, GABA is used in combination with casein peptides: GABA directly inhibits central excitability, casein peptides enhance peripheral opioid signals through the gut-brain axis, doubly reduce wakefulness drive (reduce PSQI scores), and GABA and casein peptides cover the central-peripheral dual pathways. Postbiotics and prebiotics are used in combination: postbiotics (inactivated bacteria) activate immune regulation, prebiotics (oligofructose / galactose) promote the production of SCFAs by the bacterial flora, synergistically improve 5-HT conversion efficiency, and increase intestinal 5-HT concentration. γ-Aminobutyric acid, casein peptides, postbiotics, and prebiotics form a neural-gut-brain signal linkage mechanism.

[0034] Combination of sour jujube seed powder and sour cherry powder: Sour jujube seed saponin A inhibits excessive activation of the HPA axis, and sour cherry melatonin precursor synchronously strengthens the pineal gland function, optimizing the amplitude of the cortisol / melatonin circadian rhythm. Combination of Poria cocos and lily: Poria cocos polysaccharide reduces the interference of inflammatory factors, lily saponin enhances the activity of GABAergic neurons, and multiple targets prolong the deep sleep period. Sour jujube seeds, sour cherries, Poria cocos and lilies form a synergistic effect of metabolic rhythm.

[0035] Rose and polydextrose combined: Rose fragrance quickly induces a state of relaxation (usually takes effect in 15 minutes), polydextrose slowly releases energy to maintain blood sugar homeostasis, rose rapid induction + sour cherry powder long-term regulation, forming a "rapid induction-long-term maintenance" sleep guarantee. Stevioside combined with resistant dextrin: Stevioside masks the bitter taste of herbs (palatability score ≥8.5 / 10), resistant dextrin increases satiety and reduces hunger awakening at night. Rose, polydextrose, stevioside, and resistant dextrin form a sensory-physiological reflex synergy.

[0036] Resistant dextrin is both an auxiliary material (filler) and a prebiotic. It is made from starch through a specific processing process. The human digestive enzymes have difficulty breaking down this modified starch component. Because of this, resistant dextrin can reach the large intestine intact and become food for intestinal flora, especially for promoting the growth of beneficial bacteria such as bifidobacteria and lactic acid bacteria. This type of substance helps to improve the intestinal microbial environment and promote the production of short-chain fatty acids, which in turn brings a variety of health benefits, such as improving intestinal function and enhancing immunity.

[0037] The solid beverage of the present invention realizes the full-link sleep intervention from neural regulation to metabolic optimization. The natural ingredients in the solid beverage account for more than 95%, which is in line with the general trend of healthy food.
