^a–d Mean values with different letters in the same column differ significantly (p < 0.05) by Duncan’s multiple range test. Values presented are the means ± standard deviation (N = 3/group). KFSE: The fermentation solution fermented by LP-KFY02; BFSE: The fermentation solution fermented by Lactobacillus delbrueckii subsp. bulgaricus; and WS: The solution extracted by ethanol.
