Lauroyl arginate ethyl (LAE) is a new surfactant
derived from lauric acid and arginine whose
antimicrobial properties have been shortly described
in literature. In addition to these advantages, the antimicrobial
properties of LAE remain stable from pH 3
to pH 7, suggesting that this substance may be useful
as antimicrobial agent for a wide range of food9.
Toxicological studies have determined that LAE was
rapidly metabolized by humans to the naturally occurring
dietary components lauric acid and arginine10 and
thus it is considered as a safe product. Besides, LAE
has been Generally Recognized as Safe by the FDA in
2005. Hence LAE represents a potential non odorous
alternative to essential oils for the development of new
food preservation alternatives including antimicrobial
active packaging
