Abstract
Small-molecule peptides are short-chain peptides composed of 2 to 20 amino acids, possessing a variety of biological activities such as antioxidant, anti-inflammatory, and immunomodulatory effects. The extraction of small-molecule peptides is primarily carried out using the following methods:
Enzymatic hydrolysis Proteins are hydrolyzed using specific enzymes to produce small-molecule peptides. This method boasts strong selectivity and high efficiency. Commonly used enzymes include proteases and trypsin, among others.
Acid-base method Proteins are denatured by adjusting the pH, thereby releasing small-molecule peptides. This method is simple and easy to implement, but it may affect the biological activity of the peptides.
Ultrasonic extraction Using the high-frequency vibrations of ultrasound to disrupt cell walls, thereby promoting the release of small-molecule peptides. This method boasts high extraction efficiency and can preserve the activity of the peptides.
Membrane separation method Small-molecule peptides are separated from other components using ultrafiltration or nanofiltration membranes. This method is suitable for large-scale production and can effectively remove impurities.
The main components of small-molecule peptides include:
- Collagen peptides It helps enhance skin elasticity and joint health, and is widely used in beauty and health-care products.
- Whey peptide Rich in essential amino acids, it’s ideal for athletes and fitness enthusiasts, promoting muscle recovery.
- Soy peptide It has functions such as lowering blood pressure and reducing lipids, making it suitable for cardiovascular health products.
Small-molecule peptides have a wide range of applications:
- Food industry As a functional food ingredient, it enhances the nutritional value and health benefits of foods.
- Pharmaceutical industry Used for developing new drugs, especially in areas such as cancer treatment and anti-inflammation.
- Health supplement industry As a nutritional supplement, it helps boost immunity and promote digestion.
In terms of market prospects, as people’s awareness of health continues to rise, demand for small-molecule peptides is steadily increasing. It is expected that the small-molecule peptide market will maintain rapid growth in the coming years, particularly driven by an aging society and the growing trend toward health-conscious consumption.
In short, the continuous advancement of small-molecule peptide extraction technology will drive its application across various industries and holds promise to become an important component of the health-care sector in the future.
