| Application |
Beef extract is an important animal-derived nutritional supplement in microbial culture media, particularly for bacterial media with high nutritional requirements. It is produced from fresh beef through a series of refining processes, including fat removal, heat treatment, enzymatic digestion, filtration, concentration, and spray drying, resulting in a yellowish-brown powder. Nutritionally comprehensive, it is rich in various water-soluble substances such as creatine, nucleotides, peptides, amino acids, organic acids, minerals, and vitamins. It can be widely used in the preparation of microbial culture media and fermentation processes, providing essential nitrogen sources, energy, phosphates, vitamins, and other key growth factors necessary for bacterial growth and proliferation. |
