Description: Biosynthesized ε-PL is a hydrophilic cationic linear homo-poly-amino acid typically composed of 25 to 35 identical l-lysine residues with an isoelectric point around 9.0 and is described as having a peptide bond between carboxyl groups and ε-amino groups of l-lysine residues rather than the conventional peptide bonds linking α-poly-l-lysine (α-PL). The antimicrobial activity of ε-PL was recognized more than 30 years ago, It exhibits antimicrobial activity against a spectrum of microorganisms, including bacteria and fungi. In Japan, it has been approved as a food preservative since the late 1980s. Since ε-PL’s discovery in the 1970s, it has been approved by the U.S. Food and Drug Administration in 2004 for use in boiled rice in the United States and, as described in the generally regarded as safe (GRAS) notifications 135 and 336, ε-PL can currently be applied to an assortment of food products such as soft drinks, cheese, egg-based dishes, salad dressings, fish, sauces, potato-based foods, etc. ε-PL, which possesses multiple amino groups, is highly soluble in water where it forms the antimicrobial polycationic chain (PLn+). Furthermore, ε-PL has been suggested to have an anti-obesity action because it can suppress dietary fat absorption from the small intestine by inhibiting pancreatic lipase activity even after incubation with digestive enzymes such as trypsin, α-chymotrypsin, and pepsin.
