Project Description
Product Description
Lacticaseibacillus casei (formerly named Lactobacillus casei) is a food-grade, Gram-positive, non-motile, non-spore-forming pleomorphic rod lactic acid bacterium. Cells appear as short or elongated rods less than 1.5 μm wide with flat, square ends, arranged in short or long chains, occasionally spherical single cells. Together with Lactobacillus acidophilus and Bifidobacterium strains, it is recognized as the three core beneficial intestinal microbes widely applied in global functional food manufacturing.
Our L. casei powder adopts advanced vacuum freeze-drying + multi-layer microcapsule embedding technology, using authenticated proprietary strain Lactobacillus casei LN02 isolated from natural fermented dairy sources. The finished white fine powder retains ultra-high viable activity, exhibits outstanding acid and bile salt tolerance, and can survive harsh gastric and intestinal environments to colonize the gut stably. It is a standardized active microbial raw material compliant with international food and dietary supplement production standards.
Core Functional Benefits (Modern Pharmacology & Clinical Verification)
1.Regulate Intestinal Flora Balance & Improve Digestion
After oral intake, massive viable L. casei colonizes intestinal mucosa, inhibits reproduction of harmful pathogenic bacteria, optimizes intestinal microecology, boosts secretion of digestive enzymes, and enhances nutrient absorption efficiency to relieve indigestion, bloating and irregular bowel movements.
2.Strengthen Systemic Immunity
Stimulates intestinal immune cell proliferation, promotes antibody secretion, elevates body immune defense capacity, reduces recurrent minor inflammation and seasonal physical discomfort.
3.Cardiovascular Metabolic Regulation
Assists in lowering serum cholesterol levels, dilates peripheral blood vessels to support mild blood pressure regulation, and optimizes lipid metabolism to reduce cardiovascular burden.
4.Relieve Lactose Intolerance & Alleviate Allergic Tendencies
Produces natural lactase to break down lactose, eliminating abdominal distension and diarrhea after dairy intake; modulates inflammatory cytokine secretion to ease mild food and skin allergic reactions.
5.Anti-Proliferation & Antioxidant Activity
Inhibits abnormal tumor cell proliferation via intestinal metabolic byproducts; clears intestinal free radicals to reduce long-term oxidative damage of intestinal tract.
Wide Application Fields
1.Fermented Dairy Products
Serves as primary or auxiliary fermentation starter for yogurt, fermented milk, cream, cheese, soy yogurt and plant-based fermented beverages; improves flavor texture and extends product shelf life while retaining live probiotic activity in finished dairy goods.
2.Solid Functional Beverages
Probiotic solid drink powder, prebiotic-probiotic compound powder, weight management powder, children’s gut-care milk powder; easily mixed with fruit powder, dietary fiber and mineral raw materials without activity loss during blending.
3.Dietary Supplements & Nutraceuticals
Hard capsules, vegetarian probiotic tablets, chewable probiotic candies, gut health complex supplements, post-antibiotic recovery probiotic formulas; high-CFU custom grades meet high-dose supplement formulation demands.
4.Special Medical Purpose Foods (FSMP)
Gastrointestinal recovery formula, hypoallergenic nutritional powder, elderly immune-support nutritional meals; authenticated strain LN02 passes stability testing for long-shelf-life medical food production.
5.Pet Functional Health Products
Pet intestinal care probiotic powder, cat/dog gut support chewable tablets, animal feed additive for regulating livestock digestive health.
