Sample	Protease	IC50 (mg/mL)
PX-5	Control	0.221 ± 0.005 b
	PX-5P 1	0.217 ± 0.005 b
	PX-5G 2	0.304 ± 0.005 a
PN-5	Control	0.291 ± 0.005 c
	PN-5P 1	0.308 ± 0.003 b
	PN-5G 2	0.384 ± 0.002 a

Values are averages of three measurements. Superscripts in the columns signify notable differences between values. ¹ Four hours pepsin hydrolysis. ² Four hours pancreatin hydrolysis after four hours of pepsin hydrolysis.
