Application & Usage & Packaging
Application
Yeast extract enjoys extensive application across multiple industrial fermentation fields. It is widely adopted in the production of innovative biomedicines, amino acids, vitamins and organic acids, as well as enzyme preparations and probiotic fermentation processes. Besides, it also serves as a key nutrient raw material for manufacturing biological preservatives, bio-pesticides and microecological products, acting as an essential nutritional supplement to support microbial growth in various biomanufacturing workflows.
Usage
Fully dissolved and sterilized before use.
Packaging
Compound Paper Bag with 25kg/bag or Cardboard Bucket. Reagent-grade products are packaged with 250g plastic bottle (or be packed according to the measurement requirements of customer and OEM Package as well).
Frequently Asked Questions
Q What grades of yeast extract are available, and how do they differ?
Yeast extract is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. The key differences lie in the levels of total nitrogen, amino nitrogen, and solubility. Reagent Grade offers the highest amino nitrogen content (≥3.5%) and complete solubility, while Industrial Grade is suitable for general fermentation applications.
Q Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents our general specification. We offer customization of product parameters according to customer requirements, including OEM packaging options.
Q What are the main application areas of yeast extract?
Yeast extract is widely used in industrial fermentation, including the production of biomedicines, amino acids, vitamins, organic acids, enzyme preparations, probiotics, biological preservatives, bio-pesticides, and microecological products. It serves as an essential nutritional supplement for 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 optimal performance and safety in fermentation or biomanufacturing processes.
Q What packaging options are available for yeast extract?
Standard packaging includes Compound Paper Bags at 25kg per bag or Cardboard Buckets. Reagent-grade products are available in 250g plastic bottles. Custom packaging sizes and OEM packaging can also be arranged based on customer measurement requirements.
Q What is the moisture content and pH range of yeast extract?
The moisture content for all grades is ≤6.0%. The pH of a 2% solution falls within the range of 4.5–7.5, making it compatible with a wide variety of fermentation media formulations.
