Instant lactic acid bacteria powder is a compound probiotic solid beverage designed for promoting defecation and intestinal regulation, which is committed to improving constipation and intestinal microecological imbalance from the root causes. The product has 2 grams per treaty, and the number of live bacteria detected in the factory is as high as 80 billion. The synergistic formula of "patented live bacteria, high-efficiency prebiotics, mild medicine and food homology" is adopted to promote intestinal peristalsis, soften feces and regulate flora from multiple angles. The core strains include Bifidobacterium animalis lactis subspecies U9, YRK-12, Lactobacillus paracasei L9, Lactobacillus plantarum H6, LP35, LP104, Lactobacillus fermentum CQPC04, Lactobacillus rhamnosus LRA-Y8, etc., all of which are derived from healthy human intestinal tract and have national invention patents. Among them, U9 can promote the proliferation of beneficial bacteria and regulate the microecological balance. YRK-12 cooperated with hemp seed and radish seed extracts to significantly increase the number of fecal particles and water content and shorten defecation time. L9 has good laxative function, promoting digestive enzyme secretion and intestinal peristalsis. H6 can effectively improve the intestinal propulsion rate of constipation model. LP35 has antioxidant and assists in repairing intestinal mucosa. CQPC04 and LP104 can reduce cholesterol and fat; LRA-Y8 and YRK-12 synergistically inhibit inflammatory cytokines. The product is also specially added with microcrystalline ball probiotics. Through three-layer embedding and low-temperature freeze-drying technology, the viable bacteria are protected from gastric acid safely and the number of viable bacteria reaching intestinal colonization is ensured. In terms of prebiotics, lactitol, fructooligosaccharides, inulin and isomaltooligosaccharide act synergistically, complement each other in long and short chains, rapidly proliferate beneficial bacteria, and stabilize intestinal microecology. Isomalt and erythritol in the excipients further optimize the mouthfeel and assist in softening the stool. The medicinal and edible homologous ingredients of hemp seed and radish seed extracts are mild and non-irritating, forming a lubricating film in the intestinal tract and promoting mucus secretion. The product is produced in a 100,000-class clean workshop, using water-oxygen barrier packaging to ensure high viable bacteria rate and long-term stability for 24 months. It is suitable for people with long-term constipation, intestinal dysfunction, poor metabolism and the pursuit of mild laxative programs.
