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. They differ primarily in total nitrogen content (≥7.5% vs ≥8.0%), amino nitrogen content (≥2.5% / ≥3.0% / ≥3.5%), and solubility — ranging from slightly soluble (industrial) to complete lysis (pharmaceutical & reagent). Reagent grade also requires pellucid clarity in acid/alkaline solution.
Q Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents our general specification. We offer product customization based on individual customer requirements, including tailored nitrogen levels, moisture content, and other parameters as needed.
Q What industries or applications is yeast extract suitable for?
Yeast extract is widely used across industrial fermentation, biopharmaceutical production, amino acid and vitamin manufacturing, organic acid synthesis, enzyme preparation, probiotic fermentation, biological preservatives, bio-pesticides, and microecological product development.
Q How should yeast extract be prepared before use?
Yeast extract should be fully dissolved in water and then sterilized prior to use. This ensures optimal nutrient availability and prevents contamination in fermentation or biomanufacturing processes.
Q What packaging options are available for yeast extract?
Standard packaging is a compound paper bag at 25 kg per bag or a cardboard bucket. Reagent-grade products are packaged in 250 g plastic bottles. Custom packaging quantities and OEM packaging are also available upon request.
Q What is the appearance and physical form of yeast extract?
Yeast extract is a powder with a light yellow or brown color. It carries the endemic taste and odor characteristic of the product, with no other peculiar smell, and contains no normal visible extraneous impurities.
