Abstract: Continuous processing in the production of peptides is an area of increased interest. In this study, an enzymatic membrane reactor (EMR) was developed whereby whey protein isolate was used as a substrate to prepare DPP-IV inhibitory and radical scavenging peptides via enzymatic hydrolysis. Two separate enzymes were tested: Corolase 2TS and Protamex in conventional batch processes and the EMR. Neither enzyme was considered effective at producing peptides with radical scavenging activity when measured using a DPPH assay. However, both enzymes were capable of producing DPP-IV inhibitory peptides. Corolase and Protamex both produced similar DPP-IV inhibition levels upon completion of batch experiments. In the EMR process, permeate in the Protamex run showed 33.7% lower IC50 value compared to the continuous Corolase run. Protamex was a better enzyme at producing the DPP-IV inhibitory effect. The continuous (EMR) production method showed an increased productivity over batch for both enzymes.
