Physicochemical properties of pectin from Malus domestica ‘Fălticeni’ apple pomace as affected by non-conventional extraction techniques

Six non-conventional techniques (microwave-assisted extraction, ultrasound-assisted extraction, enzyme-assisted extraction – with cellulase and Celluclast 1.5L, ultrasound-assisted extraction – heating treatment, and enzyme-assisted extraction – ultrasound treatment) and conventional citric acid extraction were applied to extract pectin from Malus domestica ‘Fălticeni’ apple pomace, and were compared in terms of extraction yields and...
