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, Pharmaceutical, and Reagent. The primary differences lie in amino nitrogen content and solubility — Reagent grade offers the highest amino nitrogen (≥3.5%) and full pellucid solubility, while Industrial grade is suitable for general fermentation applications with slightly lower purity requirements.
Q Can the product specifications be customized to meet specific requirements?
Yes. While the physicochemical index represents the general specification, the product can be fully customized according to customer requirements. OEM packaging is also available upon request.
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 other manufacturing processes.
Q What industries and applications is yeast extract suitable for?
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 an essential nutritional supplement to support microbial growth.
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 packed in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available to meet specific customer needs.
Q What is the moisture and pH specification for yeast extract?
The moisture content for all grades must not exceed 6.0%. The pH of a 2% solution should fall within the range of 4.5 to 7.5, ensuring suitability for a wide variety of fermentation and bioprocessing applications.
