2 . APPLICATION FIELDS

（1） Core Applications in Food Industry‌

Natural Preservative‌:

Dairy Products‌: Extends shelf life of milk, cheese, and yogurt by inhibiting spoilage bacteria (e.g., Listeria). Typical dosage: 0.05–0.1%.

Meat & Seafood‌: Delays microbial growth in sausages, fish, and shrimp. Applied via 1–3% spray/vacuum packaging.

Bakery & Beverages‌: Replaces chemical preservatives in cakes and low-alcohol drinks.

Functional Additive‌:

√ Enhances gut health in infant formula (≤50 mg/kg).

√ Used in active packaging films for antimicrobial effects.

（2）Key Roles in Feed Industry‌

Poultry & Livestock‌:

√ Antibiotic Alternative‌:  in poultry feed reduces diarrhea and improves growth rates.

√ Swine Health‌:  prevents postpartum infections in sows and replaces zinc oxide in piglets.

Aquaculture‌:

Disease Control‌: 400–600 g/ton prevents enteritis in fish; 1–2 kg/ton treats infections.

Shrimp/Crab‌: Essential for immune support (150–400 g/ton).

（3）Emerging Trends‌

Clean-Label Solutions‌: Combines with chitosan or nisin for synergistic preservation.

Sustainable Feed‌: Reduces antibiotic use by 30% in livestock.

3. Functional Effects

✓ Antibacterial Action‌:

Highly effective against Gram-positive bacteria (e.g., Staphylococcus aureus)

Moderate effect on some Gram-negative bacteria (e.g., Escherichia coli)

Synergistic effect when combined with antibiotics

✓ Antiviral Action‌:

Directly inactivates viral proteins

Inhibits influenza virus, HIV, etc.

✓ Immunomodulation‌:

Activates macrophage phagocytosis

Stimulates immunoglobulin production

Mechanism of Action‌:

Lysozyme specifically hydrolyzes the β-1,4-glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in bacterial peptidoglycan, disrupting cell wall integrity and causing osmotic lysis.
