Bacteriocinogenic LAB Strains for Fermented Meat Preservation: Perspectives, Challenges, and Limitations

Area of Science:

• Food Science
• Microbiology
• Biotechnology

Background:

• Lactic acid bacteria (LAB) bacteriocins are researched for biopreservation in food.
• Meat and fermented meat products face microbial contamination, posing health and economic risks.
• LAB starter cultures can produce bacteriocins during meat processing.

Purpose of the Study:

• To review the potential and challenges of using bacteriocins as food additives.
• To explore the application of bacteriocins in producing safe and healthy fermented meat products.
• To discuss the safety and technological aspects of bacteriocinogenic LAB.

Main Methods:

• Literature review of research on LAB bacteriocins.
• Analysis of bacteriocin production in vitro versus during meat processing.
• Evaluation of safety and technological characteristics of bacteriocinogenic LAB.

Main Results:

• Bacteriocin levels are typically lower during meat processing than in vitro.
• Direct addition of bacteriocins as food additives is desirable.
• Safety and technological properties of LAB are crucial for application.

Conclusions:

• Bacteriocins offer potential for safe and healthy fermented meat production.
• Further research is needed to overcome challenges in bacteriocin application.
• Optimizing bacteriocin production and ensuring safety are key for widespread use.
