The antimicrobial and bioactive properties of lactobionic acid

Area of Science:

• Food Science
• Biochemistry
• Microbiology

Background:

• Lactobionic acid (LBA) is a bioactive molecule with established chelating, moisturizing, gelling, and antioxidant properties.
• Its chemical structure, a polyhydroxy acid formed from galactose and gluconic acid, imparts unique characteristics.
• While LBA production methods are well-researched, its application in food and evaluation of antimicrobial activity are emerging areas.

Purpose of the Study:

• To review recent advances in the antimicrobial potential of LBA for food applications.
• To summarize key aspects of LBA as a promising bioactive compound for the food sector.
• To highlight the need for comprehensive studies to inform regulatory status.

Main Methods:

• Literature review focusing on antimicrobial activity of LBA against foodborne pathogens.
• Synthesis of information on LBA production methods (fermentation, biocatalysis).
• Analysis of LBA's properties relevant to food industry applications.

Main Results:

• LBA exhibits antimicrobial activity against foodborne pathogens, a relatively new area of research.
• Production of LBA via microbial fermentation and enzymatic synthesis is established.
• LBA possesses functional properties beneficial for food applications.

Conclusions:

• Lactobionic acid (LBA) is a promising bioactive compound for the food industry, particularly for its antimicrobial effects.
• Further research and comprehensive studies are needed to support its broader use and regulatory approval in foodstuffs.
• Dissemination of research findings on LBA's food-related applications could impact its regulatory standing.
