Description

Technical Field

[0001] The present invention belongs to the field of food technology, and specifically relates to a nutritious meal replacement powder containing composite probiotics and a preparation method thereof, which is particularly suitable for a meal replacement food for improving intestinal health and regulating metabolic function. Background Art

[0002] In recent years, with the accelerating pace of life and changes in dietary patterns, people's demand for healthy diets has been growing. Meal replacement powders, as a convenient, nutritious, and healthy food, have gradually gained favor among consumers. Their convenience, efficiency, and nutritional balance have made them a key choice for those pursuing a healthy diet in today's fast-paced world. However, most meal replacement powders suffer from limited functionality, nutritional imbalances, and low probiotic survival rates. Summary of the Invention

[0003] In response to the above problems, the present invention proposes a meal replacement powder based on scientific nutritional ratios and combined with highly active composite probiotics. Through an innovative preparation process, the survival rate of probiotics is guaranteed, and the dual functions of metabolic regulation and intestinal health improvement are achieved.

[0004] The technical solution of the present invention is a nutritional meal replacement powder containing compound probiotics, comprising a basic nutritional powder (92-98%) and compound probiotics (2-8%), wherein the basic nutritional powder is composed of a combination of basic nutritional components (60-80%), prebiotics (3-15%), auxiliary ingredients (15-30%) and optional ingredients (1-8%).

[0005] The basic nutritional components include: Whey protein powder 15-20%, high biological value protein, used to improve muscle metabolism; Oat β-glucan 8-12%, non-starch polysaccharide, soluble dietary fiber, used to regulate blood lipids, blood sugar and intestinal flora; 5-10% konjac glucomannan, a high-viscosity fiber, to enhance satiety; Black bean protein isolate 5-8%, a source of plant protein, used to supplement essential amino acids; Barley grass extract 2-5%, rich in vitamins and antioxidants.

[0006] The prebiotics include a mixture of inulin and oligofructose, which are used to promote the proliferation of probiotics and improve the intestinal microenvironment.

[0007] The auxiliary material ingredients include the composite probiotic embedding agent, composite vitamins (B group, C, D), minerals (calcium, zinc, selenium), and flavoring agents.

[0008] Furthermore, the flavoring agent is one or more combinations of mogroside, yeast extract, betaine (natural extraction), and steviol glycoside.

[0009] The optional ingredients are one or more combinations of N-acetylneuraminic acid (bird's nest acid), spirulina, maca powder, grape seed extract, green tea extract, and fruit and vegetable powder.

[0010] The compound probiotics include various combinations of the following ingredients: Lactobacillus rhamnosus ≥1.5×10 8 CFU, regulates the intestinal barrier to enhance immunity; Lactobacillus gasseri ≥1.5×10 8 CFU, assists in fat loss and improves abdominal fat distribution Bifidobacterium animalis subsp. lactis or Bifidobacterium animalis ≥5×10 8 CFU, synthetic B vitamins, to promote intestinal health.

[0011] Clostridium butyricum ≥ 2 × 10 8 CFU, repairs intestinal mucosa and regulates immunity.

[0012] Furthermore, the Lactobacillus rhamnosus strain preservation information is: preservation classification name: Lactobacillus rhamnosus, preservation number: CGMCCNo.34707, preservation date: May 29, 2025, preservation unit: General Microbiology Center of China Culture Collection Administration, preservation unit address: No. 3, No. 1 Beichen West Road, Chaoyang District, Beijing.

[0013] Furthermore, the composite probiotics are processed by freeze-drying protective agent embedding technology, and the number of viable bacteria is ≥1×10 9 CFU / serving.

[0014] Furthermore, the freeze-drying protective agent is a combination of maltodextrin and mannitol (natural extraction) or a mixture of skimmed milk powder, trehalose, gelatin and polygonatum polysaccharide.

[0015] Preparation method

[0016] 1. Raw material pretreatment: The basic ingredients such as whey protein powder and oat beta-glucan are made into fine powder through low-temperature spray drying (temperature ≤ 60°C) to avoid nutrient loss; The probiotic components are encapsulated with freeze-dried protective agents to ensure that the survival rate of live bacteria is ≥90%.

[0017] 2. Mixed and layered packaging: The basic nutritional components and auxiliary materials are mixed evenly in proportion and the solubility is improved by fluidized bed granulation technology; The probiotic components are individually packaged into small packets and filled with nitrogen to avoid light and oxidation.

[0018] 3. Final combination: Each serving of meal replacement powder contains 12-50g of base powder + 1g of active probiotic packet, which are dissolved separately during brewing to ensure the activity of the probiotics. Beneficial effects

[0019] (1) Nutritional balance: The basic content of protein ≥ 20% and dietary fiber ≥ 8% should be prepared to meet the basic daily nutritional needs.

[0020] (2) Highly active probiotics: through freeze-drying protection technology, the number of live bacteria ≥ 1×10 9 CFU / serving, significantly higher than traditional meal replacement powders.

[0021] (3) Functional synergy: Clostridium butyricum and inulin synergistically repair the intestinal barrier and improve metabolic syndrome. BRIEF DESCRIPTION OF THE DRAWINGS
