CPR	2	Soaking overnight, 0.2 µ microfiltration for liquid–liquid separation and 5 kDa ultrafiltration for concentration, spray drying. 4-day process
CPR	3	Soaking overnight, 0.2 µ microfiltration for liquid–liquid separation and 10 kDa ultrafiltration for concentration, oven drying. 5-day process
CPR	4	Soaking overnight, 0.2 µ microfiltration for liquid–liquid separation and 10 kDa ultrafiltration for concentration, final product in liquid form. 5-day process
HPR	1	Soaking/hydrolysis overnight at 55 °C, enzymatic extraction at pH 8, 0.2 µ microfiltration for liquid–liquid separation and 10 kDa ultrafiltration for concentration, spray drying.
HPR	2	Soaking/hydrolysis overnight at 58 °C, enzymatic extraction at pH 6.7, 0.2 µ microfiltration for liquid–liquid separation and 300 Da nanofiltration for concentration, spray drying.
HPR	3	Soaking/hydrolysis for ca. 4 h at 50 °C, enzymatic extraction at pH 5.0 for 1 h followed by pH adjustment to pH 7.0 a subsequent 30 min reaction time, 0.2 µ microfiltration for liquid–liquid separation and 300 Da nanofiltration for concentration, final product in liquid form.
