Supercritical fluids extraction of bioactive molecules from Apple Pomace

Résumé

Apple (Malus domestica Borkh.) is one of the more common fruit in Europe and the fourth most consumed fruit in the world (Musacchi & Serra, 2018). According to the Food and Agriculture Organization of the United Nations, more than 86 million tonnes were produced in 2020 around the world and 11.8 million tonnes in the European Union (FAOSTAT). According to Kammerer et al. (2014), apple juice is the most value-added product with an annual production of 25% to 30% of total crop. Apple pomace (AP) is a left-over obtained after pressing the apples. It contains peels, flesh, seeds, and stem. About 12 million tonnes of AP waste is produced in the world (Martău et al., 2021). This left-over found several applications and uses, namely in animal feeding, biofuel and ethanol production (via fermentation), compost and biogas (Kennedy et al., 1999). According to International Energy Agency, Europe is the main user and producer of biogas, 18 Mtoe in 2018 against 7 Mtoe for China, 4 Mtoe for USA and for the rest of the world. Yet, in most countries, AP is discarded, and buried in soil (Lyu et al., 2020). Clearly these procedures cannot valorise the valuable phytochemicals present in AP. The main phenolic compounds are phloridzin, quercetin glycosides, and chlorogenic acids, all molecules with high added value (Suárez et al., 2010). Besides antioxidant and anti-ageing properties, these compounds showed interesting antibacterial and antifungal activity. This work focuses on the valorisation of AP by extraction with supercritical CO2. The extraction experiments could provide optimized yield preserving the biological activities of the extracts. The extracts were tested on Escherichia coli and Bacillus megaterium.
