Sustainable extraction of apple pomace to recovery the bioactive compounds with pro-health properties

About 44% of the total amount of waste generated in the world is food and green waste [ 1 ] including by-products from the agri-food industry such as the apple juice. The disposal of the apple pomace can cause serious environmental problems or even public health hazards if it is not managed or proceseed properly. Nowdays, the recovery rate of AP is quite low and insufficient. Therefore in this work we examined different ways of apple pomace extraction including conventional and sustainable methods of extraction i.e. ultrasound-assisted (UAE), enzyme-assisted (EAE), β-cyclodextrin-assisted (CAE) and pressured solvent extraction (PSE). The extracts were examined by the chemical composition (polyphenols, terpenoids, fatty acids, vitamins, minerals), antioxidant properties (in DPPH, ABTS, FRAP, CUPRAC, lipid peroxidation spectrophotometric assays). The biocompatibility of the extract and the cellur antioxidant potential of extracts were examined on human epidermal cells (HaCaT). The obtained results showed that the way of extraction extremelly affects the chemical composition and biological activity of apple pomace extracts. The obtained extracts are valuable biomaterials that can be applied in agri-food-health industry [ 2 ].
