^aIC₅₀: The sample concentration (mg/ml) required to inhibit 50 % of the ACE activity

^abcdefghijIn each column, means with different letters are significantly different (p < 0.05) for a particular treatment

0.0 % starter means that the mix starter culture contained only Lactobacillus delbrueckiisubs. bulgaricus and Streptoccusthermophilus (without probiotic bacteria)
