By maintaining strict microbiological control and biological assays, we ensure that every batch of probiotic strains meets the absolute peak of cell viability and gastrointestinal passage survival.
Delivering biological stability and active cell density on an industrial scale.
How Shaanxi Diaries Biotech solves the critical challenge of cell viability and metabolic activity.
The industrial applicability of probiotics hinges on a singular parameter: active cell survival rate from factory packaging to customer consumption. Probiotic ingredients are highly sensitive to thermal gradients, mechanical shear stress, relative humidity ($a_w$), and gastric acidity. At Shaanxi Diaries Biotech, our Ph.D.-led engineering team has designed a multi-layer stabilization system to address these thermodynamic and physiological bottlenecks.
Using a proprietary blend of disaccharides and antioxidant polymers, we form an amorphous glassy matrix around cell membranes during freeze-drying. This prevents the crystallization of intracellular water, eliminating structural shearing of Lactobacilli and Bifidobacteria membranes.
For applications exposing bacteria to extreme heat (like tablets or animal feed pelleting), we apply a lipid and alginate coating. This micro-shield preserves strain viability under thermal loads of up to 85°C and prevents gastric juice degradation.
We operate cleanrooms at a strict relative humidity level of <20%. By driving final product water activity ($a_w$) below 0.15, we halt cellular respiration, extending product shelf life to 24 months under ambient conditions.
Custom probiotic solutions engineered to yield high-efficacy clinical outcomes across market segments.

Tour our state-of-the-art facility in Xi'an, Shaanxi Province, equipped with modern GMP automation.
Our production base spans over 70,000 square meters, utilizing six advanced plant extraction production lines and fine extraction workshops. Operating under strict GMP-compliant systems, we maintain automated raw material processing, high-throughput extraction, and cleanroom packaging to prevent cross-contamination.
Fulfilling rigorous global verification requirements for large-scale operations.
Quality assurance is not a checklist; it is the cornerstone of our manufacturing design. Shaanxi Diaries Biotech operates under strict international regulatory compliance frameworks, assuring product identity, safety, and traceability. Our certifications include:
Navigating international shipping timelines requires robust planning. We provide global supply chain resilience through:
Advancing the science of microbiome optimization through biotechnology.
The next phase of microbiome science is shifting towards precision therapeutics. Shaanxi Diaries Biotech is heavily investing in clinical validation and isolation of novel strains targeting the Gut-Brain Axis, Metabolic Homeostasis, and Immunological Modulation. Our current R&D pipeline is focused on three primary areas:
Direct answers for purchasing teams, quality assurance directors, and formulation engineers.
Our freeze-dried powders are standardly available in concentrations ranging from 10 Billion (1.0 x 10^10) to 100 Billion (1.0 x 10^11) CFU/g. We also manufacture super-concentrated formulations reaching up to 400 Billion CFU/g for select strains like Bacillus coagulans and Lactobacillus rhamnosus.
For sensitive strains, we pack our products in triple-laminated aluminum foil bags with moisture absorbers, shipped in heavy-duty styrofoam coolers containing gel dry-ice packs. We closely monitor seasonal temperatures along transit paths and utilize express air freight to ensure the shipment reaches your facility within safe thermal parameters.
Yes, our strains like Bacillus subtilis and Pediococcus acidilactici are specifically selected and certified as feed-grade. These spore-forming and microencapsulated strains are highly resilient against thermal mechanical friction during feed extrusion and pelleting, maintaining effective CFU counts in the finished animal feed.
We provide full-service OEM and contract manufacturing options. This includes blending multiple strains, adding functional plant extracts, formatting into oral capsules, tablets, or sachets, and packaging them under your brand with complete regulatory documentation support.
Broaden your product range with our validated bulk ingredients for sports, cosmetics, and agricultural applications.
