Effects of Quillaja saponaria extract and Nα-lauroyl-l-arginine ethyl ester on reducing selected foodborne pathogens in vitro and maintaining quality of fresh-cut endive (Cichorium endivia L.) at pilot plant scale
Quillaja saponaria extract (QSE) and Nα-lauroyl-l-arginine ethylester (LAE) is used. Antimicrobial activity was examined in vitro against selected foodborne pathogens. LAE reduced the microbial load of the endive wash water below the detection limit. QSE combined with warm water washing best retained endive sensory appearance. QSE and LAE are suitable as wash water additives in fresh-cut lettuce processing.
