In this study, pectolytic enzymes (Pectinex BE XXL, Trenolin Rot, and Fructozym P) were investigated for their influence on phenolic, anthocyanin content, and antioxidant activities of elderberry (Sambucus nigra L.) pulps during juice processing. Prior to pressing the berries, three different enzymes were added to pulps in order to evaluate the effect of different pectolytic enzyme treatments on the valuable components of elderberry juice. Control sample was prepared without enzyme. After treatment, squeezing, and clarification steps, microfiltration was carried out with ceramic membrane. The effect of this technology on the antioxidant capacity, total polyphenol content, and total anthocyanin content of the clarified elderberry juices has been evaluated in permeate and retentate samples, and membrane retention was calculated. Significantly lower antioxidant capacity was detected in the case of control sample than that obtained using enzyme-treated juices. Retention of antioxidant content on the microfiltration membrane was greatly reduced by using the enzymes. Higher valuable component yield was obtained using Fructozym P enzyme compared with Pectinex BE XXL used in industry.
