China Yeast Extract Powder from China Suppliers - High-Purity Nitrogen Source for Fermentation Culture Media Factory Manufacturers, Manufacturer

,

Yeast extract powder, a premium product manufactured in China, is a fine, dry light yellow powder derived primarily from fresh beer yeast and baker’s yeast. Utilizing advanced biotechnology, our factory employs controlled autolysis or enzymatic hydrolysis methods to thoroughly break down yeast cell structures. Through a meticulous process of separation, purification, concentration, and advanced spray drying, we ensure the final product boasts a stable texture and high purity.

Frequently Asked Questions

Q What are the different grades of yeast extract available?
Yeast extract is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. Each grade differs in total nitrogen content, amino nitrogen levels, and solubility to meet specific application requirements.
Q Can the product specifications be customized?
Yes. While the physicochemical index represents our general specification, we are able to customize the product according to individual customer requirements. OEM packaging is also available upon request.
Q How should yeast extract be prepared before use?
The yeast extract should be fully dissolved and sterilized prior to use to ensure optimal performance and safety in fermentation or other biomanufacturing processes.
Q What industries or applications is yeast extract suitable for?
Yeast extract is suitable for a wide range of applications including the production of biomedicines, amino acids, vitamins, organic acids, enzyme preparations, probiotic fermentation, biological preservatives, bio-pesticides, and microecological products.
Q What packaging options are available for yeast extract?
Standard packaging is a compound paper bag at 25kg per bag or a cardboard bucket. Reagent-grade products are available in 250g plastic bottles. Custom packaging sizes and OEM packaging can also be arranged based on customer needs.
Q What is the moisture and ash content specification for yeast extract?
Across all three grades — Industrial, Pharmaceutical, and Reagent — the moisture content must be ≤6.0% and the ash content (on dry matter basis) must be ≤15.0%, ensuring consistent product quality and stability.
