EXPLANATION
Food Preservatives, Bacteriocins (Nisin), Antimicrobial Packaging and Shelf-Life Extension
- Allicin $\to$ (II) Garlic: Diallyl thiosulfinate produced when alliin is hydrolyzed by alliinase upon crushing garlic (Allium sativum); potent broad-spectrum antibacterial agent.
- Eugenol $\to$ (III) Clove: Phenylpropanoid volatile phenolic oil isolated from cloves (Syzygium aromaticum); disrupts bacterial cell membranes.
- Lysozyme $\to$ (I) Eggs: Muramidase enzyme abundant in hen egg albumen ($3.4\%$ of total protein); cleaves $\beta(1\to 4)$ glycosidic bonds in bacterial peptidoglycan.
- Lactoperoxidase $\to$ (IV) Milk: Endogenous indigenous enzyme in raw bovine milk that oxidizes thiocyanate in the presence of $H_2O_2$ into bactericidal hypothiocyanite ($OSCN^-$).
Correct option: (3) (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
