a,b means with different superscripts within the same column differ significantly (p < 0.05) between storage temperatures. x,y means with different superscripts within the same row are significantly different (p < 0.05) between storage duration. Mean is presented ± standard error of means, SEM. Temp: temperature; Dur: duration; * nd means no microbial growth detected.
