The health-relevant functionality of Mucuna pruriens was improved by priming the seeds with elicitors of the pentose phosphate pathway (PPP) such as fish protein hydrolysates (FPHs), lactoferrin (LF) and oregano extract (OE) followed by dark germination. FPH elicited the highest phenolic content of 19mg/g FW on day 1, which was 38% higher than control sprouts. OE enhanced Parkinson's disease-relevant L-DOPA content by 33% on day 1 compared to control sprouts. Anti-diabetes-relevant α-amylase inhibition percent (AIP) and α-glucosidase inhibition percent (GIP) were high in the cotyledons and decreased following elicitation and sprouting. For potential anti-diabetic applications, low AIP and high GIP with moderate L-DOPA content on day 4 of dark germination could be optimal. Improved L-DOPA concentrations in a soluble phenolic and antioxidant-rich M. pruriens background on day 1 sprouts have potential for Parkinson's disease management.
