Explore our core bio-ingredients and active formulations ready for global logistics
Pioneering Probiotic Freeze-Drying and Bio-Ingredient Innovations Since 2002
Welcome to Shaanxi ShineHerb Biotech Co., Ltd., a professional high-tech enterprise strategically engaged in the research, dynamic isolation, optimization, industrial-scale production, and global export of high-activity probiotic strain powders, enzyme preparations, natural plant extracts, premium vitamins, amino acids, and high-purity pharmaceutical intermediates. Nestled in the world-renowned Hi-Tech Zone of Xi'an, Shaanxi Province, China, we bring over two decades of highly focused industry experience to the table.
"With over 20 years of expertise, we supply biological solutions to pharmaceutical manufacturers, dietary supplement formulators, and cosmetic global brands in more than 50 countries, meeting strict international monographs (USP, EP, CP)."
By investing in multi-stage continuous bio-reactors, ultra-clean cleanroom processing blocks, and high-capacity freeze-drying lines, ShineHerb Biotech ensures that heat-sensitive biological structures (especially probiotic membranes and active metabolic protein complexes) survive the rigorous processing steps. We guarantee active cell count density and physical stability across shelf life.
Over two decades of sustained biological cultivation and technical development.
Exporting premium ingredients globally with a robust logistic system.
Strict regulatory compliance ensures seamless clearance for foreign customs.
Deciphering the preservation kinetics that deliver ultra-stable probiotics to market
Lactobacillus acidophilus is an indispensable lactic acid bacteria (LAB) strain native to the human gastrointestinal tract. Historically used for fermented dairy, modern biotechnology leverages L. acidophilus to enhance immune responses, fortify the digestive barrier, and actively compete against opportunistic pathogenic microflora. However, the true bottleneck of commercial industrial supply chains lies in maintaining strain viability (expressed in Colony-Forming Units, or CFU) from our fermenters, through transportation, and ultimately onto consumer shelves.
During the freezing stage of lyophilization, ice crystals can pierce bacterial cell walls, leading to cell death. ShineHerb Biotech utilizes a patented cryoprotective matrix containing precise ratios of natural disaccharides, amino acids, and phosphate buffers. This creates a protective "glass transition" state ($T_g$) around the cell membrane, preventing lysis and structural degradation.
Residual moisture is the main driver of protein degradation and metabolic decay. Our deep freeze-drying systems strictly dry the powder until water activity ($a_w$) drops below 0.15. This metabolic immobilization preserves the cell structure in a safe state, preventing degradation even at room temperature.
Industrial strains must survive gastric transit. Our selected strains of Lactobacillus acidophilus exhibit robust survivability when exposed to artificial gastric juice (pH 2.0) and bovine bile salts, ensuring high-dose physiological colonisation in the lower gut.
The manufacturing process is meticulously managed. From initial seed inoculation in sterile stainless steel bioreactors to secondary concentration using low-shear tubular membranes, every single operational parameter (dissolved oxygen, pH profiling, nitrogen purging, and thermal gradients) is monitored in real-time. The result is a powder with high flowability, minimal dust, and consistent strain potency (available from $5.0 \times 10^{10}$ CFU/g up to premium concentrates of $5.0 \times 10^{11}$ CFU/g).
How our automated production lines protect raw material flow and lower manufacturing cost
Modern raw material sourcing demands absolute predictability. Fluctuations in batch quality and sudden logistical disruptions are top risks for global supplement brands. ShineHerb Biotech addresses these challenges by adopting Factory 4.0 standards across our production facilities in Shaanxi.
By integrating programmable logic controllers (PLCs) with multi-stage computerized control systems, our fermentation and freeze-drying processes minimize human error. Our factory's closed-loop purification system keeps air quality under ISO 7 (Class 10,000) standards, preventing cross-contamination with wild microflora.
Ensuring Batch Stability: Every single batch of Freeze-Dried *Lactobacillus acidophilus* powder undergoes comprehensive verification. We utilize advanced flow cytometry to count viable cells, as well as traditional agar plating. This ensures that the active cell counts on our Certificates of Analysis (COAs) accurately reflect live, functional organisms, rather than dead biomass.
Supply Chain Redundancy: We maintain strategic raw material stockpiles (high-grade peptones, protective carbohydrates, and packaging foils) to guard against regional disruptions, guaranteeing stable output even during peak demand seasons.
Adapting active probiotics to complex dietary supplement and pharmaceutical delivery formats
The global demand for Lactobacillus acidophilus extends far beyond simple capsule fillings. Our B2B clients require specialized, application-specific formulations tailored to distinct consumer categories. Our freeze-dried powders are optimized for easy integration into several key markets:
Our powders are designed for dry blending into multi-strain hard gelatin or vegetable capsules, standard tablets, and direct-to-mouth powder sachets. The low water activity of our powder ensures it remains compatible when blended with vitamins, prebiotics (FOS, GOS, Inulin), and minerals.
Ideal for infant formulas, powdered functional milks, meal replacement shakes, and cereal fortifying mixes. Our thermal stabilization technology protects the bacterial cells from temporary heat spikes during standard powder mixing processes.
Emerging research confirms the role of the skin microbiome. We offer specialized, non-viable lysates and active, low-moisture probiotic powders designed for water-free skincare formulas, highlighting protective skin barrier benefits.
High-grade agricultural probiotic batches are supplied to feed producers seeking to improve digestive efficiency and reduce antibiotic dependency in livestock, poultry, and aquaculture operations.
Providing the documentation needed to meet international regulatory standards
Entering international consumer health markets requires extensive compliance documentation. Without verified safety data, foreign customs and regulatory bodies (such as the US FDA or EFSA) may block entry. ShineHerb Biotech eliminates regulatory risk by maintaining a comprehensive set of globally recognized certifications.

One-stop manufacturing services for private label supplement brands
Do you want to launch a unique brand of dietary supplements without building your own production lines? ShineHerb Biotech provides full-format, customized contract manufacturing solutions. We transform our premium freeze-dried probiotic powders into finished, market-ready products.
Our experienced R&D team works directly with you to formulate, pilot test, stabilize, and design labels that comply with regional labeling laws in North America, Europe, and Asia.
Investing in the next generation of microbiome stabilization and delivery systems
As gut health science advances, standard freeze-drying techniques must evolve to meet new challenges. ShineHerb Biotech is actively researching and developing next-generation probiotic stabilization technologies:
We are piloting micro-coatings of lipid bilayers and protein-polysaccharide complexes around individual *L. acidophilus* cells. This provides enhanced protection against severe tableting pressure and high-moisture environments.
By co-lyophilizing beneficial bacteria with prebiotic fibers and metabolic postbiotics (like short-chain fatty acids), we create highly functional, multi-action health ingredients.
Using whole-genome sequencing (WGS), we verify that our *L. acidophilus* strains do not carry transferable antibiotic-resistance genes, meeting the strict safety guidelines set by global food authorities.
Transparent supply chains backed by high-speed shipping networks
Probiotics are temperature-sensitive biological materials. At ShineHerb Biotech, we manage the entire logistics process. We offer customized packaging (insulated boxes, gel ice packs, vacuum sealed double-layer bags) and utilize reliable shipping options (FedEx, DHL, air cargo, and refrigerated ocean freight) with full tracking to ensure your order arrives in optimal condition.
