Article Synopsis
- Olive pomace, a toxic by-product of olive oil production, can be valorized using novel microwave-assisted extraction (MAE) techniques.
- The study focused on maximizing the extraction of total polyphenol content (TPC) and antioxidant activity (AA) through response surface methodology, analyzing the impacts of solid ratio, time, and power.
- Optimal conditions for the highest TPC (15.30 mg GAE/gdw) and AA (10 mg AAE/gdw) were found to be 800 W, 180 seconds, and a solid concentration of 1 g/50 mL.
Enzymatic hydrolysis of soybean milk proteins with cysteine protease papain was performed in an advanced bioreactor, operated with batch mode. In soybean milk protein hydrolysis reaction, enzyme and substrate ratio and reaction temperature were varied, ranging from 0.029:100-0.

Factorial design was applied to measure the influences of transmembrane pressure (10-20 bar) and temperature (20-40 ℃) on the retention of valuable components such as anthocyanins and resveratrol, and on the nanofiltration membrane performance. The highest retention of anthocyanin and resveratrol was achieved at low temperature (20 ℃), while the high transmembrane pressure (20 bar) was found to increase the permeate flux considerably.
