Explore our high-performance organic nitrogen formulations and media base components manufactured under strict ISO and Halal guidelines.
Casein Hydrolysate is a complex mixture of amino acids, peptides, and polypeptides obtained by the controlled enzymatic or acid hydrolysis of casein—the primary protein source found in bovine milk. In modern biotechnology, clinical nutrition, and industrial fermentation, it serves as an indispensable source of highly bioavailable organic nitrogen.
Unlike inorganic nitrogen sources, casein hydrolysate delivers a full spectrum of free amino acids (particularly high concentrations of glutamic acid, proline, and leucine) alongside crucial growth-promoting oligopeptides. These components are readily absorbed by microorganisms and mammalian cells, eliminating the metabolic energy required to synthesize amino acids from scratch. The enzymatic process relies on refined pancreatin or alternative proteases, allowing manufacturers to control the degree of hydrolysis (DH) to match specific cellular assimilation pathways.
Globally, the market for casein hydrolysates is undergoing rapid expansion. This growth is fueled by the surging demand for biopharmaceuticals (such as monoclonal antibodies and recombinant proteins), the global rise of probiotic foods, and the expansion of clinical diagnostics. Global procurement managers now prioritize suppliers that can guarantee lot-to-lot consistency, low endotoxin levels, and high solubility under industrial sterilization conditions.
How Beijing Hongrun Baoshun Technology Co., Ltd. Bridges Advanced R&D with Scalable, High-Precision Manufacturing.
Our Sichuan facility utilizes completely isolated production lines for animal-derived and plant-derived products. This layout eliminates cross-contamination risks and complies with strict Halal and biopharma safety standards.
Founded in 2008 and headquartered in the Science and Technology Innovation Area of the China (Beijing) Pilot Free Trade Zone, Beijing Hongrun Baoshun Technology Co., Ltd. is a high-tech enterprise integrating R&D, large-scale production, and global export. Our manufacturing capabilities were significantly upgraded in 2018 with the launch of our production base in Langzhong, Sichuan.
With an investment spanning Phase I and Phase II facilities, our Sichuan footprint covers over 40,000 square meters. Here, our state-of-the-art spray drying, filtration, and hydrolysis reactors produce animal-derived and plant-derived nitrogen sources under highly controlled parameters. This structural separation is vital for global buyers requiring certified allergen control, animal-free compliance, or Halal certification.
Leveraging a network of five specialized subsidiaries—including Beijing Yaoyou Technology, Sichuan Baoshun Biotechnology, Sichuan Romgee Biotechnology, Sichuan Yingwen Technology, and Sichuan Runxiaobao Technology—we manage the entire supply chain. From raw material sourcing to enzymatic optimization and final distribution, this integrated structure allows us to offer consistent quality, customized batch sizes, and flexible pricing models.
Our commitment to quality is backed by ISO 9001:2015 and MUI Halal certifications. Adhering to the rule of "no substandard products leaving the factory," our in-house laboratories perform HPLC analysis, molecular weight distribution mapping, solubility testing, and microbiological counts on every batch before release.

Serving diverse biotechnology sectors with tailored organic nitrogen formulations.
In clinical microbiology and industrial diagnostics, casein hydrolysates are the backbone of dehydrated media formulation (e.g., Mueller-Hinton agar, Tryptic Soy Broth). Thanks to its rich content of tryptophan and other essential amino acids, our casein hydrolysate enables rapid bacterial growth, consistent pigment production, and reliable antibiotic susceptibility testing.
For biopharmaceutical production, animal-derived raw materials are subject to strict regulatory scrutiny. We offer customized casein hydrolysate fractions with controlled low-molecular-weight peptide distributions. These products are thoroughly screened for endotoxins and elemental impurities, providing stable growth kinetics for mammalian cell cultures and recombinant bacterial strains.
The manufacturing of probiotics (such as Lactobacillus and Bifidobacterium species) requires highly bioavailable organic nitrogen. Our peptones and yeast extracts supply the specific peptides and vitamins needed to achieve high colony-forming unit (CFU) counts and enhance cell viability during freeze-drying processes.
We develop custom formulations tailored to specific industries, applications, and functions. This service helps clients adapt to evolving microbial strains and changing regulatory requirements.
The global biotechnology landscape is shifting toward precision fermentation, animal-free raw materials, and circular economies. In response to these dynamics, Beijing Hongrun Baoshun Technology Co., Ltd. is continually expanding its research into alternative plant-derived nitrogen sources, including high-purity soy, wheat, and pea peptones.
Additionally, we are refining our enzymatic hydrolysis processes using advanced computational enzyme design. This approach allows us to target specific peptide linkages, helping us develop custom casein hydrolysates with precise molecular weight profiles tailored to the metabolic needs of specific cells.
Looking ahead, we remain committed to technological innovation, quality control, and excellent customer service. We are ready to collaborate with global partners to support the growth of the biotechnology and life sciences industries.
