∗LB0 is Lishe bora immediately after preparation; LB4 is Lishe bora 4 hours after preparation; SRP0 is soy-rice porridge immediately after preparation; and SRP4 is soy-rice porridge 4 hours after preparation
†Bacterial counts in mean Log10 cfu/g; the assay cannot detect values <50 cfu/g
‡Mean±SD, with ANOVA p value and post-hoc bonferroni test comparing water, LB0, and SRP0; LB0 and LB4; SRP0 and SRP4; LB4, SRP4, and traditional foods
¶Comparisons with unlike superscripts (a, b, c, and d) indicate significant differences (p<0.05) between subgroups; ANOVA=Analysis of variance; cfu=Colony-forming unit; LB=Lishe bora; SRP=Soy-rice porridge; SD=Standard deviation
