China Beef Extract Powder - Biological Fermentation, Organic Nitrogen, Nutrient-Rich Microbial Culture Suppliers & Factory

Beef extract powder, typically found in tan or dark brown hues, is a premium product developed through biological hydrolysis that transforms beef macromolecules into easily digestible nutrients. This powder is rich in essential components such as creatine, peptides, amino acids, nucleotides, vitamins, and minerals, notably abundant in methionine and essential growth factors that support bacterial metabolism and proliferation. The production process begins with fresh beef, which is defatted and subjected to enzymatic digestion to extract active nutrients. Following thorough filtration to eliminate impurities, the resulting liquid is concentrated and then spray-dried to create a fine powder that effectively preserves its nutritional value, As a leading product from China, our beef extract powder is highly sought after by suppliers and is extensively used as a core nutrient source in microbial culture media for laboratories and biopharmaceutical fermentation. Additionally, it enhances the flavor and nutritional profile in food processing, establishing itself as an essential raw material in both biological research and the food industry. Trust our factory to deliver high-quality beef extract powder that meets your needs

Frequently Asked Questions

Q
What are the main quality indicators of beef extract?
The key physicochemical indicators include total nitrogen (≥14.0% on DM), amino nitrogen (≥2.5% on DM), ash (≤13% on DM), moisture (≤6.0%), pH 4.5–7.0 in a 2% solution, and a pellucid solubility in 2% solution. Sensory properties include a light yellow powder appearance with no caking or extraneous impurities.
Q
Can the physicochemical specifications be customized?
Yes. While the listed physicochemical index represents our general specification, we are able to customize the product formulation and specifications according to the specific requirements of each customer.
Q
What is beef extract typically used for?
Beef extract is widely used in biological laboratories and large-scale microbial fermentation industries. It serves as a high-grade nitrogen source in culture media, providing peptides, amino acids, and natural growth factors to support microbial growth and metabolism.
Q
How should beef extract be prepared before use?
Beef extract should be fully dissolved in the appropriate volume of water and sterilized before use. Proper dissolution ensures consistent performance in culture media applications.
Q
What packaging options are available?
Beef extract is available in compound paper bags (25kg/bag) or cardboard buckets for bulk use. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging quantities and OEM packaging services are also offered to meet customer needs.
Q
How does beef extract differ from peptone in culture media?
Beef extract effectively compensates for the nutritional deficiencies of peptone and other common nitrogen sources. It provides a broader spectrum of natural growth factors alongside peptides and amino acids, making it a complementary and often superior choice for optimizing cultivation efficiency and strain activity.
