LT, lag time (day: 5°C, h: 15 and 25°C); SGR, maximum specific growth rate (log CFU/day: 5°C, log CFU/h: 15 and 25°C); MPD, the maximum population density (log CFU/g).
NFOJ, non-fermented onion juice; FOJ, fermented onion juice; CQDs, onion-peel-derived CQDs; CFC, combination of FOJ and CQDs.
All values are presented as mean±SD (n=3).
Different superscript letters within the same temperature, pathogen, and growth parameter (LT, SGR, or MPD) indicate significant differences among marination treatments (Duncan’s multiple range test, p<0.05).
