Frequently Asked Questions
What is beef extract and what is it made from?
Beef extract is a light yellow powder derived from beef, rich in peptides, amino acids, and natural growth factors. It is produced to serve as a high-quality nitrogen source for use in microbiological culture media and fermentation applications.
What are the key quality specifications for this beef extract?
The product features a total nitrogen content of ≥14.0% (on DM), amino nitrogen ≥2.5%, ash ≤13%, moisture ≤6.0%, pH of 4.5–7.0 (2% solution), and a pellucid solubility at 2% solution. It appears as a light yellow powder with no caking or extraneous impurities.
Can the product specifications be customized?
Yes. While the physicochemical index represents the general specification, we can customize the product according to the specific requirements of each customer, including tailored nitrogen levels and other parameters.
How should beef extract be prepared before use?
The product should be fully dissolved in water and then sterilized before use to ensure safety and effectiveness in your culture media or fermentation process.
What packaging options are available?
Beef extract is available in Compound Paper Bags (25kg/bag), Cardboard Buckets, and 250g plastic bottles for reagent-grade products. Custom packaging sizes and OEM packaging are also available upon request.
In which industries is beef extract commonly used?
Beef extract is widely used in biological laboratories and large-scale microbial fermentation industries. It is valued as a high-grade raw material for optimizing cultivation efficiency, supporting microbial growth, and enhancing strain activity in culture media.
