Wholesale Yeast Extract Powder - High Purity Nutrient Source from China Suppliers and Factory for Fermentation Media Manufacturer, Factories

Yeast extract powder is a high-quality, fine, dry light yellow powder primarily derived from fresh beer yeast and baker's yeast. Produced using advanced biotechnology, this product undergoes controlled autolysis or enzymatic hydrolysis, ensuring a thorough breakdown of yeast cell structures. The meticulous process includes systematic separation, purification, and concentration, followed by advanced spray drying treatment, resulting in a product with stable texture and high purity, Rich in balanced nutrients, our yeast extract powder offers a complex mix of free amino acids, small molecular peptides, abundant water-soluble vitamins, and carbohydrates like oligosaccharides and trehalose. With exceptional solubility and remarkable nutritional activity, it serves as an excellent source of nitrogen, growth factors, and trace elements. This yeast extract is widely utilized in preparing microbial culture media and is essential in biological fermentation, biopharmaceuticals, and the food industry, For businesses seeking reliable China suppliers and factory sources, our yeast extract powder effectively promotes microbial proliferation and metabolism in both industrial production and laboratory research

Frequently Asked Questions

Q1 What are the available grades of yeast extract and how do they differ?
Yeast extract is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. They differ mainly in total nitrogen content, amino nitrogen content, and solubility. Reagent Grade has the highest amino nitrogen (≥3.5%) and requires complete lysis and pellucid clarity in solution, making it suitable for more precise laboratory and pharmaceutical applications.
Q2 Can the physicochemical specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents the general specification. We offer customization of product parameters based on the specific requirements of each customer to best suit their application needs.
Q3 In which industries is yeast extract most commonly used?
Yeast extract is widely used across industrial fermentation fields, including the production of biomedicines, amino acids, vitamins, organic acids, enzyme preparations, probiotics, biological preservatives, bio-pesticides, and microecological products. It serves as a key nutritional supplement supporting microbial growth in biomanufacturing.
Q4 How should yeast extract be prepared before use?
Yeast extract should be fully dissolved and then sterilized before use. This ensures the product is properly integrated into the fermentation medium and free from contamination that could affect microbial cultures.
Q5 What packaging options are available for yeast extract?
Standard packaging options include Compound Paper Bags (25kg/bag) and Cardboard Buckets. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging according to customer measurement requirements and OEM packaging are also available upon request.
Q6 What is the moisture and pH specification for yeast extract?
Across all grades, the moisture content is controlled at ≤6.0%. The pH of a 2% solution falls within the range of 4.5–7.5, ensuring consistent quality and stability for use in various fermentation and biomanufacturing applications.
