High-purity animal, plant, and yeast-derived peptones manufactured under strict ISO and Halal regulations.
A deep dive into nitrogen profiling, amino acid consistency, and metabolic pathways.
Peptone Water is a foundational non-selective culture medium used primarily in microbiological diagnostic workflows, quality control protocols, and biological fermentation processes. Functioning as a premium nitrogen source, it supplies essential nutrient factors, including free amino acids, low-molecular-weight peptides, and critical growth factors necessary for the resuscitation and rapid proliferation of demanding microorganisms.
In standard food safety and clinical testing protocols (such as ISO 6579 for Salmonella detection), Buffered Peptone Water (BPW) plays a pivotal role in the pre-enrichment stage. Microorganisms present in processed foods are often sub-lethally injured by heat, desiccation, acidity, or preservative exposures. Standard selective media inhibit these damaged cells. Non-selective pre-enrichment in a stable, isotonic peptone solution provides the physiological recovery phase needed before subsequent selective isolation.
Our formulation is meticulously standardized to ensure maximum consistency across batches. By maintaining precise hydrolysis rates of animal and plant proteins, we achieve optimal ratios of free amino acids to total nitrogen. The high concentration of polypeptide chains provides excellent buffering capacity, shielding cultures from metabolic-induced pH fluctuations during early-stage incubation.

A dual-certified national "High-tech Enterprise" and "Zhongguancun High-tech Enterprise" pioneering modern bio-fermentation.
Established in 2008 and rooted in the Science and Technology Innovation Area of the China (Beijing) Pilot Free Trade Zone, Beijing Hongrun Baoshun Technology Co., Ltd. has developed into a leading high-tech enterprise integrating R&D, advanced manufacturing, and global sales. We dedicate ourselves to the research of microbial raw materials, serving the pharmaceutical, diagnostic, and bioprocessing industries.
In 2018, we expanded our industrial presence to Langzhong, Sichuan, establishing a modern 40,000 square meter factory complex. With phase I and phase II factories fully operational, and backed by a 20,000 square meter temperature-controlled logistics hub, we guarantee bulk availability and consistent supply. Our state-of-the-art facility features dedicated, completely separated animal and plant processing lines, eliminating cross-contamination risk and ensuring product purity.
Why global pharmaceutical and diagnostic companies select Hongrun Baoshun as their primary supply partner.
We provide microbial fermentation raw materials from animal, plant, and yeast sources, meeting all customization requirements for dehydrated and liquid media.
Full-process independent production lines at our Sichuan base guarantee robust capacity and highly controllable delivery lead times for large-scale orders.
Adhering to strict standards, we conduct comprehensive testing on all batches. No product leaves our factory without meeting our rigorous quality controls.
To assure fit-for-purpose performance, we offer free validation samples up to 500g per product class (excluding international shipping fees).
Addressing complex sourcing challenges and shifting industrial requirements.
International procurement teams require full raw material traceability. For animal-derived peptones (beef, casein, pork), proving BSE/TSE-free status is critical for pharmaceutical applications. For plant-based media (wheat, soy, corn steep powder), GMO declarations and allergen control are vital. Hongrun Baoshun provides complete COA, allergen, and origin certification with every batch.
Driven by regulatory bodies and consumer demand, the industry is transitioning toward animal-free culture media. Our plant and yeast peptone lines offer chemically defined profiles that serve as direct substitutes for beef peptone and tryptone, maintaining high yield without biological safety risks.
With global supply chains facing uncertainty, companies seek reliable manufacturing partners with large raw material reserves. Our Langzhong base holds up to 20,000 square meters of stock, ensuring a stable buffer and competitive pricing during market fluctuations.

Automated manufacturing systems allow us to fulfill bulk orders quickly and reliably.
Our sales and support teams communicate clearly in multiple languages, ensuring efficient order handling.
Expert technical answers to common queries on peptone water media and biological raw materials.
Standard Peptone Water contains only peptone (as a source of nitrogen and amino acids) and sodium chloride (for osmotic stability). Buffered Peptone Water (BPW) adds a phosphate buffer system (disodium phosphate and monopotassium phosphate). The buffer system is critical when analyzing food or environmental samples containing sub-lethally injured cells, as it maintains the pH around 7.0 ± 0.2 and prevents bacterial acid production from killing the resuscitating cells.
Our Sichuan facility features physically separated production lines for animal and plant hydrolysis. Each line has dedicated spray dryers, grinding equipment, and packaging systems. This prevents trace cross-contamination, ensuring that plant-derived products remain 100% vegan and allergen-controlled, while meeting MUI Halal requirements.
We provide comprehensive export documentation, including a Certificate of Analysis (COA) detailing physical, chemical, and microbiological parameters, Phytosanitary Certificates, Halal Certificates, and Material Safety Data Sheets (MSDS). For animal-derived peptones, we also supply veterinary and origin certificates confirming BSE/TSE-free status.
We offer free evaluation samples up to 500g for most peptones and yeast extracts. Customers only need to cover the international shipping fees. Please contact our sales team to submit your company details and specify the peptone classes you require for testing.
Our dehydrated peptone powders have a shelf life of 36 months when stored in original, unopened packaging. Peptones are highly hygroscopic and should be stored in dry, cool conditions (between 10°C and 30°C) away from direct sunlight. Once opened, reseal the container tightly to prevent moisture absorption and caking.
