Lysozyme is widely used in the food industry as a natural preservative due to its ability to inhibit the growth of bacteria. It is particularly effective in dairy products like cheese, where it helps prevent spoilage by targeting harmful bacteria. In the pharmaceutical sector, lysozyme is incorporated into medications and eye drops for its antimicrobial properties, aiding in the treatment of infections. Additionally, it is utilized in biotechnology research as a tool for cell lysis and protein extraction. Its role in the immune system also makes it a valuable component in dietary supplements aimed at boosting immunity.
