China Yeast Extract Powder Supplier - High Purity Fermentation Culture Media from Trusted Factory

Yeast extract powder is a finely milled, light yellow powder derived primarily from fresh beer yeast and baker’s yeast. This product is produced in China using advanced biotechnology methods, including controlled autolysis and enzymatic hydrolysis, which effectively dismantle yeast cell structures for maximum efficacy. After a thorough process of separation, purification, concentration, and innovative spray drying, our yeast extract powder emerges with a stable composition and high purity, Rich in balanced nutrients, this complex mixture contains free amino acids, small molecular peptides, water-soluble vitamins, and carbohydrates such as oligosaccharides and trehalose. With its outstanding solubility and remarkable nutritional activity, it serves as a vital source of nitrogen, growth factors, and trace elements. Our yeast extract powder is predominantly utilized in the preparation of microbial culture media, playing a crucial role in the fields of biological fermentation, biopharmaceuticals, and the food industry. It significantly enhances microbial proliferation and metabolism, making it an essential product for both industrial production and laboratory research, As a leading supplier and factory of yeast extract powder in China, we are committed to providing high-quality products that meet the diverse needs of our clients across various sectors

Frequently Asked Questions

Q What grades of yeast extract are available, and what are the key differences?
Yeast extract is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. The primary differences lie in nitrogen content, amino nitrogen levels, and solubility. Reagent Grade offers the highest amino nitrogen (≥3.5%) and complete pellucid solubility, making it suitable for the most demanding applications, while Industrial Grade serves standard fermentation processes.
Q Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents our general specification. We can customize the product according to individual customer requirements, including tailored nitrogen levels, moisture content, and other parameters.
Q What industries and applications is yeast extract commonly used in?
Yeast extract is widely used across multiple industrial fermentation fields, including the production of biomedicines, amino acids, vitamins, organic acids, enzyme preparations, probiotics, biological preservatives, bio-pesticides, and microecological products. It acts as an essential nutritional supplement to support microbial growth in biomanufacturing.
Q How should yeast extract be prepared before use?
Yeast extract should be fully dissolved in water and sterilized prior to use to ensure product safety and optimal performance in fermentation or other microbial growth applications.
Q What packaging options are available for yeast extract?
Standard packaging includes Compound Paper Bags at 25kg/bag or Cardboard Buckets for bulk orders. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available upon customer request.
Q What are the storage and appearance characteristics of yeast extract?
Yeast extract appears as a light yellow or brown powder with the endemic taste and odor characteristic of the product, with no other peculiar smell. It should be stored in a cool, dry place, away from moisture, to maintain its quality and shelf life. Moisture content is controlled at ≤6.0% across all grades.
