A core advantage of nisin is its outstanding safety profile, which is recognized globally by regulatory authorities (e.g., the U.S. FDA, EU EFSA) as "Generally Recognized as Safe (GRAS)". Its safety is rooted in two key characteristics: Natural origin and biodegradability: Nisin is biosynthesized by Lactococcus lactis—a lactic acid bacterium commonly used in food fermentation (e.g., cheese, yogurt production)—meaning it is not a synthetic chemical. In the human body, it is rapidly broken down by proteolytic enzymes (e.g., trypsin in the gut) into harmless amino acids, leaving no toxic residues or accumulating in tissues. This eliminates concerns about long-term dietary exposure risks associated with some synthetic preservatives (e.g., potential metabolic burdens from artificial additives). Low toxicity even at extended use: Extensive toxicological studies have confirmed that nisin has no acute, chronic, or genotoxic effects on humans at approved usage levels. It is also safe for vulnerable groups such as infants, pregnant women, and the elderly, making it suitable for a wide range of food products targeting diverse populations.
