Phenolic Compounds Recovery from Pomegranate ( L.) By-Products of Pressurized Liquid Extraction.

This study aimed to valorize pomegranate by-products (peel and carpelar membranes-PPCM) through their high biological potential for phenolic compounds recovery. The influence of lower temperatures (40 and 60 °C) and pressures (20, 40, 60, 80, and 100 bar) than those generally used in pressurized liquid extraction (PLE) was evaluated through global extraction yield (X), and qualitative and quantitative composition of the phenolic compounds. Chromatographic techniques were used to analyze the two treatments with the highest X.
