Explore our core selection of animal, plant, and yeast-derived nutritional ingredients formulated for high-yield microbial growth.
Within high-performance microbial fermentation, the search term "Homemade Yeast Extract" represents a specialized industrial paradigm rather than basic kitchen autolysis. It refers to customized, proprietary-strain autolyzed yeast derivatives manufactured via client-specific extraction paths. By departing from rigid, bulk commodity yeast extracts used in standard food applications, industrial-grade customized (homemade) yeast extracts deliver tailormade free amino acid ratios, nucleoside abundance, and growth factor balances designed for fastidious organisms.
Globally, the demand for specialized organic nitrogen sources is expanding rapidly. Biopharmaceuticals, industrial enzymes, and microecological preparations require strict, batch-to-batch nutritional consistency. Standard commercial baker's or brewer's yeast byproducts often carry varying trace properties that can disrupt metabolic pathways in delicate biological processes. Our proprietary manufacturing approach bypasses these limitations by focusing on controlled growth, targeted autolysis, and precise enzymatic cleavage of selective yeast strains.
Established in 2008 and based 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 biomanufacturing enterprise. We specialize in the research, development, production, and distribution of high-purity nitrogen sources and microbial culture media.
We are recognized as a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise". In 2018, we expanded our production capacity by establishing a major facility in the Qili Industrial Park in Langzhong, Sichuan. With Phase I and Phase II factories exceeding 40,000 square meters and maintaining a 20,000 square meter dedicated storage facility, we support bulk supply requirements across global markets with reliable consistency.
Our operation integrates five specialized companies to maintain complete quality control from initial strain isolation through to international delivery.
Focuses on advanced microbiological assay development and clinical diagnostics culture media formulation research.
Manages large-scale bulk plant and animal protein extraction processes, ensuring low-ash organic nitrogen sources.
Specializes in targeted enzymatic hydrolysis research to create customized peptones for biological production.
Leads custom analytical testing and quality verification processes, checking every production lot before release.
Oversees cold-chain logistics, international distribution networks, and global client support structures.
A view into our advanced production lines and cleanrooms that maintain trace-element control in our finished powders.
In global industrial fermentation, raw materials must satisfy both performance standards and regulatory criteria. Certifications like MUI Halal, Kosher, and ISO 9001:2015 are essential for food, feed, and pharmaceutical applications. Production strains must be kept free of animal-derived components to prevent Transmissible Spongiform Encephalopathy (TSE/BSE) risks. This requirement has shifted industry preference toward plant peptones and high-purity yeast extracts.
Our plant-derived peptones (including wheat and potato-based peptones) and yeast extract powders are processed on isolated, non-animal production lines. This setup prevents cross-contamination and allows biotech companies to satisfy global safety requirements for modern biological therapeutics.

Our export team handles documentation, phytosanitary certificates, and customs clearance requirements.
We provide complimentary validation samples (up to 500g per product) to confirm compatibility before purchasing.
To produce high-purity yeast extracts, our process uses precise enzymatic hydrolysis. We grow pure strains of Saccharomyces cerevisiae in carbon-controlled fermenters. After harvesting, the yeast cells undergo controlled autolysis under specific temperature and pH profiles.
We add food-grade endopeptidases and exopeptidases to hydrolyze structural proteins into soluble short-chain peptides and free amino acids. The soluble fraction is separated using high-speed centrifuges, purified via ultrafiltration to remove bitter components, concentrated in vacuum evaporators, and spray-dried into a dust-free powder. This process preserves heat-sensitive B-complex vitamins, nucleotides, and trace elements, making it suitable for delicate biomanufacturing applications.
Our ingredients support cell growth and product yields across multiple biological sectors.
Acts as a primary nitrogen source in dehydrated formulations, agar plating media, and biochemical testing reagents.
Supports the production of therapeutic proteins, recombinant vaccines, and monoclonal antibodies in mammalian cell systems.
Provides critical vitamins and trace growth factors required to synthesize industrial amylases, proteases, and lipases.
Provides essential growth factors like purines and pyrimidines to support high cell-density growth in probiotic strains.
Used in biopesticides and plant growth-promoting rhizobacteria (PGPR) formulations to support eco-friendly crop management.
Supplements nutrient levels in microbial cultures used for wastewater treatment, hydrocarbon breakdown, and soil restoration.
A closer look at how our customized plant, animal, and yeast extracts support various industrial categories.
Different industrial strains require specific nutritional inputs. Standard peptones often contain varying salt ratios or mineral footprints that can affect secondary metabolite production. Factors like environmental air composition and water quality variations between countries also influence culture media performance.
To address this variability, Hongrun Baoshun offers customization services for international bioprocessing operations. We can modify hydrolysis levels, target specific molecular weight profiles, adjust sodium chloride levels, or combine raw materials (e.g., blending yeast extract with peptones) to support target yields for your strains.

Expert answers addressing purity, molecular profiles, customization options, and global shipping standards.
Industrial customized (often referred to as "homemade") yeast extracts are processed to optimize bio-availability for micro-organisms. Food-grade extracts focus on flavor compounds like monosodium glutamate (MSG) and 5'-ribonucleotides. In contrast, our fermentation-grade extracts prioritize free amino nitrogen (FAN), intact growth factors, B-complex vitamins, and low sodium levels to prevent osmotic stress in microbial cells.
We maintain fully isolated plant-derived and animal-derived production lines at our Sichuan manufacturing base. This isolation prevents cross-contamination, helping us satisfy Animal-Derived Component-Free (ADCF) requirements for sensitive biopharma applications.
We offer a validation program providing up to 500g of sample material per product. Customers can evaluate these samples in their own pilot fermenters to assess cell density and target yields before committing to commercial volumes.
Our dry powders are hygroscopic and should be stored in cool, dry conditions (≤ 25°C) in their original moisture-barrier packaging. We ship using double-polyethylene lined fiber drums or heavy-duty sealed bags to limit humidity exposure during transit.
We use standardized enzymatic digestion profiles and automated filtration systems to control molecular weights. Every batch is tested using high-performance liquid chromatography (HPLC) to verify amino acid profiles and check for consistent nitrogen content.
