Is ε-Poly-L-Lysine safe to Eat
Yes, it is considered safer than chemical preservatives as it is natural and it is partly hydrolyzed to L-lysine (an essential amino acid) after ingested by the human body. It has the function of both preservation and nutrition fortification.

Its safety has been approved by the Japan Ministry of Health, Labour and Welfare, U.S. Food and Drug Administration in 2003 and afterward, National Health Commission of the People’s Republic of China (NHC) approved it in 2014. It is also authorized in some other countries.

Chemical synthetic preservatives (e.g. sodium benzoate, potassium sorbate) are widely used in food to extend shelf life in today’s food industry. However, the health concerns surrounding them are always coming up which makes consumers afraid of the safety of their food and seeks safe preservatives, and thus biological preservatives stand out.
