‌Lactoperoxidase‌

CAS NO.: 9003-99-0
Specification: 100,000U/g
Appearance: White Powder

Function‌
1. Delays milk spoilage:
Helps maintain the quality and flavor of dairy products, preventing spoilage and off-flavors caused by microbial contamination.
2. Inhibits Psychrotrophic Bacteria:
Remains effective even at refrigeration temperatures, preventing spoilage and off-flavors in milk and meat products.
3. Boosts Immune Function:
Found in high concentrations in breast milk and bovine colostrum; as a key component of colostrum, it significantly enhances the body's immune function.
4. Improves Gastrointestinal Function:
Helps protect the gastrointestinal tract against pathogenic microorganisms, thereby improving gastrointestinal health.
5. Promotes Tissue Growth and Physical Development:
Plays a positive role in the tissue growth and physical development of newborns.
6. Protects Mammary Gland Health:
Helps maintain mammary gland health in lactating women.
7. Synergistic Antimicrobial Effect:
Works synergistically with nutrients such as lactoferrin and immunoglobulins to deliver enhanced antimicrobial effects.

Key Application
1. Food Industry:
Cold preservation of raw milk; shelf-life extension without reliance on refrigeration; preservation of meat products, fruits, and vegetables; natural food preservative (PMC)
2. Oral Care:
Toothpaste and mouthwash; inhibition of dental plaque, gum protection, and caries prevention; mild antibacterial action; partial replacement of chemical antibacterial agents (PMC)
3. Cosmetics:
Natural preservation systems; skincare ingredients; antibacterial properties; reduction in the use of traditional preservatives
4. Biomedicine:
Research related to oral mucosa and wound care

Description About Lactoperoxidase‌
Lactoperoxidase (LPO) is a heme-containing enzyme found in milk, saliva, tears, and airway secretions. It plays a key role in the body's natural defense system by producing antimicrobial compounds. It is an important component of the natural defense systems of humans and animals, serving functions such as antimicrobial activity, protection, and food preservation.
Lactoperoxidase catalyzes reactions that generate highly oxidizing substances, effectively inhibiting the growth and proliferation of various bacteria; this plays a crucial role in food preservation and extends the product's shelf life.
Lactoperoxidase participates in redox reactions to produce bactericidal agents—such as hypothiocyanite—that disrupt bacterial cell membranes and enzyme systems, thereby halting normal bacterial metabolism and proliferation and ensuring the stability of food quality over time.
Lactoperoxidase boosts the body's natural immune defense mechanisms by enhancing the activity of immune cells (such as leukocytes), thereby increasing resistance to pathogens and reducing the risk of infectious diseases.
In oral care, lactoperoxidase inhibits the growth of cariogenic bacteria and reduces plaque formation, helping to prevent oral conditions such as dental caries and periodontitis.
