Description

Technical Field

[0001] This invention relates to the field of nourishing beverage technology, and more specifically to an easily absorbed nourishing beverage and its preparation method. Background Technology

[0002] As products that combine nutritional supplementation and health conditioning, tonic drinks have seen continuous market growth. Currently, tonic drinks on the market can be mainly divided into two categories: traditional and functional. Traditional tonic drinks primarily use traditional tonic ingredients such as donkey-hide gelatin, bird's nest, and ginseng as their core, prepared through simple stewing, soaking, or extraction processes. While they have a certain market recognition based on traditional tonic concepts, they are limited by the characteristics of the ingredients and the level of processing, resulting in products that generally suffer from a single nutritional composition and poor convenience of consumption. Functional tonic drinks, on the other hand, combine modern food processing technology with added functional ingredients, emphasizing selling points such as "highly effective supplementation" and "precise conditioning," and are gradually becoming the mainstream in the market, especially among sub-healthy individuals, post-operative recovery patients, and those seeking beauty and anti-aging benefits. However, judging from actual application effects and consumer feedback, existing health supplements still have many technical defects that urgently need to be addressed. These defects not only restrict the effectiveness of the products but also limit their scope of application. Among them, low absorption efficiency is the most critical and prominent problem currently facing the industry. Specifically, key nutrients in traditional health supplements, such as collagen and active ingredients from traditional Chinese medicine, such as ginsenosides and astragalus polysaccharides, exist in a large molecular structure. Digestive enzymes in the human digestive system cannot quickly and fully break them down into small molecules that can be directly absorbed. This results in these nutrients staying in the intestines for too long, with some even being excreted unabsorbed through metabolism. Related research data shows that the peak concentration of free amino acids in the blood of large molecular nutrients in traditional health supplements generally occurs more than 60 minutes later, with a bioavailability of less than 30%, far from meeting consumers' demand for "highly efficient supplementation." Besides absorption efficiency issues, the easy deactivation of active ingredients is also a significant drawback affecting the quality and efficacy of tonic drinks. Probiotics, vitamins, and other heat-sensitive ingredients commonly used in functional tonic drinks are extremely sensitive to environmental factors such as temperature, oxygen, and light. High-temperature processing during product preparation (such as sterilization and drying) and oxygen exposure during storage can easily lead to reduced activity or even complete deactivation. For example, in tonic drinks containing probiotics prepared using ordinary processes, the survival rate of probiotics is often less than 50% after 30 days of storage at 4-8℃, while the oxidative degradation rate of vitamin C during storage can reach over 40%. This means that by the time the product reaches the consumer, its claimed functions have been significantly reduced, making it difficult to achieve the expected tonic effects. Meanwhile, the limited target population significantly restricts the market coverage of health supplements. Currently, most health supplements, in pursuit of taste and flavor, add traditional sugars such as sucrose and high-fructose corn syrup as sweeteners, resulting in a glycemic index (GI) generally exceeding 50. These products not only fail to meet the needs of special populations requiring sugar control, such as diabetics and obese individuals, but also contradict the modern consumer's "low-sugar, sugar-controlled" healthy eating philosophy. Furthermore, existing products lack targeted formulation design, failing to consider the physiological characteristics and nutritional needs of different groups (such as children and post-operative recovery patients). For example, children have lower tolerance to certain active ingredients in traditional Chinese medicine, and post-operative patients have higher protein absorption rates and repair needs, but there are few health supplements specifically designed for these groups on the market, leading to insufficient product universality. In conclusion, while the health supplement beverage market is developing rapidly, deficiencies in absorption efficiency, active ingredient stability, and suitability for different population groups have become bottlenecks for industry development. Therefore, developing a health supplement beverage that can overcome existing technological limitations, achieve efficient nutrient absorption, ensure long-term stability of active ingredients, and cater to the needs of diverse populations is not only key to addressing consumer pain points but also an inevitable trend driving the health supplement beverage industry towards higher quality and more refined products. This is also the core technological problem that this invention aims to overcome. Summary of the Invention

[0034] I. Core Performance Indicators and Measurement Methods (a) Absorption efficiency related indicators 1. Peak concentration of free amino acids in blood (reflecting the absorption rate of small molecule peptides) Measurement method: Forty healthy volunteers (aged 25-35 years, half male and half female) were randomly divided into 8 groups (corresponding to Examples 1-3 and Comparative Examples 1-5). Each group consumed 500ml of sample on an empty stomach, and 2ml of venous blood was collected at 0 min, 15 min, 30 min, 45 min, and 60 min. The concentration of free amino acids in the blood was determined using high-performance liquid chromatography (HPLC). Chromatographic conditions: C18 column (250 mm × 4.6 mm, 5 μm), mobile phase: 0.1% phosphoric acid aqueous solution-acetonitrile (95:5, v / v), flow rate: 1.0 mL / min, column temperature: 35 ℃, detection wavelength: 220 nm; Calculate the peak concentration and time to peak at 30 min, and take the average value for each group.

[0035] Judgment criteria: The higher the peak concentration and the shorter the time to reach the peak, the stronger the absorption efficiency.

[0036] 2. Proliferation rate of beneficial intestinal bacteria (reflecting the prebiotic efficacy of fructooligosaccharides) Measurement method: One day before volunteers drank the sample and 14 days after drinking it, 0.5g of fecal samples were collected and cultured using a selective culture medium method. Bifidobacterium: BS medium, anaerobic culture at 37℃ for 48 h; Lactobacillus acidophilus: MRS medium, anaerobic culture at 37℃ for 48 h; Calculate "(number of colonies after drinking - number of colonies before drinking) / number of colonies before drinking × 100%", which is the beneficial bacteria proliferation rate.

[0037] Judgment criteria: A proliferation rate of ≥50% is considered effective, and ≥100% is considered significantly effective.

[0038] (ii) Stability indicators of active ingredients Probiotic survival rate (reflecting the protective effect of microcapsules) Measurement method: After sample preparation, 10 ml samples were taken at 0, 15, and 30 days (refrigerated at 4-8℃) and analyzed using the plate count method. The sample was serially diluted with sterile physiological saline (10) -6 -10 -8 (Double), take 0.1 ml and spread it on an MRS agar plate, incubate anaerobically at 37℃ for 72 h, and count the number of viable bacteria; Calculate "30-day viable count / 0-day viable count × 100%", which is the 30-day survival rate.

[0039] Judgment criteria: Survival rate ≥80% is considered excellent stability, 60%-80% is considered good, and <60% is considered unqualified.

[0040] (III) Nutritional efficacy related indicators 1. Collagen synthesis promotion rate (reflecting the synergistic effect of small molecule peptides and vitamin C) Measurement method: Volunteers consumed the samples continuously for 28 days, and the concentration of type I procollagen N-terminal peptide (PⅠNP, a marker of collagen synthesis) in serum was measured using enzyme-linked immunosorbent assay (ELISA). The concentration of PINP was measured before drinking and 28 days after drinking using a human PINP ELISA kit (sensitivity 0.1 ng / mL) following the instructions. Calculate "(concentration after drinking - concentration before drinking) / concentration before drinking × 100%", which is the synthesis promotion rate.

[0041] Judgment criteria: A promotion rate of ≥15% is considered effective, and ≥20% is considered significantly effective.

[0042] 2. Blood glucose fluctuation value (reflecting the suitability of blood glucose control) Measurement method: Volunteers with normal blood glucose levels (fasting blood glucose 4.4-6.1 mmol / L) were selected, and their fingertip blood glucose was measured using a portable blood glucose meter before drinking the sample and at 30 min, 60 min, and 120 min after drinking it. Calculate the "highest blood glucose after drinking - fasting blood glucose before drinking", which is the blood glucose fluctuation value.

[0043] Judgment criteria: Fluctuation value ≤0.8mmol / L is suitable for low GI, and ≤0.5mmol / L is suitable for people who need to control their blood sugar.

[0044] (iv) Safety indicators 1. Microbiological indicators (total bacterial count, coliform bacteria) Measurement method: Perform the procedures according to the National Food Safety Standard for Microbiological Examination of Food (GB 4789.2, GB 4789.3): Total bacterial count: Plate pour method, incubated at 37°C for 48 hours for counting; Coliform bacteria: lactose fermentation method, cultured at 36℃ for 24-48h, and gas production was observed.

[0045] Judgment criteria: Total bacterial count ≤100 CFU / ml, and no coliform bacteria detected are considered acceptable.

[0046] 2. Heavy metal content (lead, arsenic) Measurement method: The lead and arsenic contents were determined in accordance with the National Food Safety Standard for Limits of Contaminants in Food (GB 2762) and by inductively coupled plasma mass spectrometry (ICP-MS).

[0047] Judgment criteria: Lead < 0.1 mg / kg, Arsenic < 0.05 mg / kg are considered qualified.
