Table 2 Cell apoptosis in Caco-2 exposed to gastrointestinal (GI) digests in different concentration

Concentration (mg/mL)	0	2.5	5	10
Apoptosis rate (%)	0^d	0.535^c	4.79^b	5.29^a

^a-d Means (n=3) with different concentration, cell apoptosis in Caco-2 exposed to GI digests were significantly different (p<0.05).
