Freeze drying technology of peptide freeze-dried powder:

Peptide freeze-dried powder generally includes mannitol, trehalose, tripeptides, oligopeptides, adenosine, small naked algae polysaccharides, hydrolyzed collagen, sodium hyaluronate, etc. According to the freeze-drying requirements of peptide freeze-dried powder, different concentrations of formulas can be formulated for optimization, and finally a suitable freeze-drying formula can be optimized.

The advantages of peptide freeze-drying technology are obvious, but there are still some difficulties in the actual production process:

1. Peptide stability issue: During the freeze-drying process, if the freeze-drying process is not well controlled, some peptides are prone to denaturation and loss of biological activity. In addition, changes in temperature and vacuum conditions during the freeze-drying process may also affect the stability of peptides.

2. The balance between freeze-drying rate and peptide activity: In the production process of freeze-dried peptides, increasing the freeze-drying rate can shorten the production cycle and reduce costs, but too fast a sublimation rate may damage the peptide structure and affect its biological activity. Therefore, in the exploration stage of freeze-drying process, it is also very important to control the balance between freeze-drying equipment, freeze-drying process and production efficiency.

3. Difficulty in removing moisture: Some of the moisture in peptides exists in solid form, and if the freeze-drying process is not well controlled, it is difficult to remove. This moisture may lead to a decrease in the stability of peptides during storage.

4. Equipment investment and operating costs: Freeze drying equipment requires significant investment and operating costs, which puts certain economic pressure on small and medium-sized enterprises to achieve peptide freeze-drying production.
