Frequently Asked Questions

Q 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 primarily in total nitrogen content, amino nitrogen content, and solubility. Reagent Grade offers the highest amino nitrogen (≥3.5%) and requires complete lysis in a 2% solution, while Industrial Grade has slightly lower specifications and is suitable for general fermentation applications.
Q Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents general specifications. Customized formulations can be produced to meet specific customer requirements, including tailored nitrogen levels, moisture content, and packaging configurations.
Q What are the main application fields of yeast extract?
Yeast extract is widely used across industrial fermentation sectors 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 in biomanufacturing.
Q How should yeast extract be prepared before use?
Yeast extract should be fully dissolved in water and then sterilized prior to use in fermentation or other applications. This ensures proper solubilization and eliminates potential microbial contamination before it is introduced into the production process.
Q What packaging options are available for yeast extract?
Standard packaging includes compound paper bags at 25kg per bag or cardboard buckets for bulk quantities. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging sizes and OEM packaging solutions are also available upon request.
Q What is the appearance and sensory profile of yeast extract?
Yeast extract is a light yellow or brown powder with an endemic taste and odor characteristic of the product. It contains no visible extraneous impurities and has no other peculiar smell, ensuring consistent quality for industrial and pharmaceutical applications.
