Differentiation by Phenolic Profile of Apple Juices Prepared According to Two Membrane Techniques


Crossflow filtration techniques (microand ultrafiltration), using inorganic membranes, were employed to clarify apple juice. Changes in the polyphenol composition (procyanidins, hydroxycinnamic derivatives, and dihydrochalcones) were monitored throughout the clarification process by means of a simple and reliable HPLC procedure. A factorial repeated… (More)
