Abstract:

This paper describes a comparative study of extraction methods such as maceration, pressurized liquid extraction, ultrasound assisted extraction or microwave assisted extraction with different solvents of bioactive compounds from pomaces of four different apple varieties. In order to evaluate their chemical composition the obtained extracts were analysed by High Performance Liquid Chromatography – UV detection – Evaporative Light Scattering Detection (HPLC-UV-ELSD). The study revealed that, while extraction solvent influences the recovery of different compounds, the extraction techniques do not induce selectivity since any major differences of the extracts fingerprints and of the relative proportion of compounds were observed.

Keywords:

apple pomace, extraction, maceration, pressurized liquid, ultrasound, microwave, bioactive compounds.
