The selectivity of the PHWE process on eriocitrin and hesperidin extraction was also tested. The highest total phenolic content (TPC) (59.57 mg gallic acid equivalents g(-1)), total flavonoid content (TFC) (8.22 mg catechin equivalents g(-1)) and antioxidant capacity by DPPH (42.59 mg Trolox equivalents (TE) g(-1)) were obtained at 160 degrees C for 30 min. The maximum eriocitrin (30.41 mg g(-1)) and hesperidin (25.90 mg g(-1)) contents were achieved at 160 degrees C for 5 min with a 5-hydroxymethyl furfural content of 0.07 mg g(-1). PHWE provided better results for individual compounds and antioxidant capacities than conventional extraction. The results indicated the potentiality of PHWE in the selective extraction of eriocitrin and hesperidin from lemon peel by controlling the extraction temperature and time.eninfo:eu-repo/semantics/closedAccessBioactive compoundseriocitrinhesperidinlemon peelpressurised hot water extractionArticle5842060206610.1111/ijfs.159252-s2.0-85132992205Q1WOS:000818029900001Q2
