China Yeast Extract Powder Suppliers | High-Purity Fermentation Culture Media from Factory

Yeast extract powder, a fine and light yellow powder, is primarily derived from fresh beer yeast and baker's yeast. Produced using advanced biotechnology, this product undergoes controlled autolysis or enzymatic hydrolysis to thoroughly break down yeast cell structures. Following a meticulous process of separation, purification, concentration, and advanced spray drying, the result is a high-purity yeast extract with a stable texture, As a rich source of balanced nutrients, this complex mixture contains free amino acids, small molecular peptides, abundant water-soluble vitamins, and carbohydrates like oligosaccharides and trehalose. With excellent solubility and significant nutritional activity, it offers essential nitrogen sources, growth factors, and trace elements, Our yeast extract powder is widely utilized in various applications, including the preparation of microbial culture media and in sectors such as biological fermentation, biopharmaceuticals, and the food industry. It effectively enhances microbial proliferation and metabolism, making it an essential component for industrial production and laboratory research, As a leading supplier and factory of high-quality yeast extract powder in China, we are committed to providing products that meet the highest standards, ensuring exceptional performance in microbial applications

Frequently Asked Questions

Q1 What grades of yeast extract are available, and what are the key differences?
Three grades are offered: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. The main differences lie in total nitrogen, amino nitrogen content, and solubility. Reagent Grade has the highest amino nitrogen (≥3.5%) and requires complete lysis and pellucid clarity, making it suitable for the most demanding applications.
Q2 Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents general specifications. Products can be customized according to individual customer requirements, including tailored nitrogen levels, moisture content, and other parameters.
Q3 What are the main application areas of this yeast extract?
This yeast extract is widely used in 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 a key nutritional supplement to support microbial growth.
Q4 How should the yeast extract be prepared before use?
The product must be fully dissolved and sterilized prior to use. This ensures optimal performance and prevents contamination in fermentation or biomanufacturing processes.
Q5 What packaging options are available for this product?
Standard packaging includes Compound Paper Bags at 25kg/bag or Cardboard Buckets. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available upon request.
Q6 What are the storage and shelf-life recommendations for yeast extract powder?
As a dry powder product with moisture content controlled at ≤6.0%, it should be stored in a cool, dry, and well-ventilated environment away from direct sunlight and moisture. Proper sealing after opening is recommended to maintain product quality and extend shelf life.
