Natural Antimicrobials for Food Biopreservation
ثبت نشده
چکیده
Biopreservation or biocontrol refers to the use of natural or controlled microbiota, or its antibacterial products to extend the shelf life and enhance the safety of foods (Stiles 1996 ). Since lactic acid bacteria (LAB) occur naturally in many food systems and have a long history of safe use in fermented foods, thus classed as Generally Regarded As Safe (GRAS), they have a great potential for extended use in biopreservation. Antimicrobial substances from other natural sources, such as antimicrobial proteins or peptides from animal secretions, or bioactive molecules from plant or animal defense systems have also been exploited in different ways for food biopreservation.
