Table 5. Antioxidant activity of LAB strains as measured by DPPH radical scavenging activity and β-carotene bleaching inhibitory activity

Strains	DPPH radical scavenging activity (%)	β-Carotene bleaching inhibitory activity (%)
L. plantarum SY46	49.84±0.41^c	80.23±1.25^c
L. brevis SY65	48.64±0.34^b	76.16±0.64^b
L. rhamnosus GG	45.17±0.35^a	71.83±0.53^a

Data are expressed as mean±standard deviation.
Values with different superscript letters in the same column are significantly different (p<0.05).
