Within dairy commodities like cheese and condensed milk, the preservative utilized is______________________?
Show answer Hide answer
Answer: C. Nisim
Explanation
Nisin works effectively as a natural antimicrobial peptide against foodborne pathogens. The compound prevents spoilage in processed dairy commodities by inhibiting bacterial growth. Food manufacturers utilize this specific peptide to extend the shelf life of cheese. Nisin is produced by certain strains of the bacterium Lactococcus lactis naturally. It belongs to a class of peptides known as lantibiotics containing unusual amino acids. The substance targets Gram-positive bacteria by disrupting their cellular membrane integrity.
Dairy preservation relies heavily on antimicrobial agents to maintain safety and quality standards. Cheese makers use such natural preservatives to prevent late blowing caused by clostridia. Consumer demand for natural food additives has increased the commercial use of nisin. Epexider is not a recognized natural antimicrobial preservative utilized within the dairy industry. Parabens are synthetic chemical preservatives more commonly found in cosmetics than dairy foods. Nisim is simply a slight misspelling of the correct natural peptide preservative nisin.
