Table 4.
Quantities of commercial starters and MC5 survival counts (108 CFU/mL) in four groups of yogurt during storage. Data represented as the model-fitted mean ± standard errors. “A, B, C, D” indicate significant differences within yogurt groups in different storage at p < 0.05. “a, b, c, d” indicate significant differences within different strains of the same storage time at p < 0.05.
