This study will focus on the effect of production of juices from apple and pear fruits, by using centrifugal decanter and tangential filtration, on the profile of polyphenols as a valuable source of bioactive compounds. Likewise, by-products from the juice industry were characterized in order to understand the high-value-added potential based on their composition of polyphenols. Briefly, apple and apple juice showed great contents of chlorogenic acid (0.990 \u00b1 0.021 mg\/g of DW), the dihydrochalcone phloridzin (1.041 \u00b1 0.062 mg\/g of DW), procyanidins (0.733 \u00b1 0.121 mg\/g of DW) and quercetin derivatives (1.501 \u00b1 0.192 mg\/g of DW). Likewise, the most abundant compounds in pear and pear juices were chlorogenic acid (0.917 \u00b1 0.021 mg\/g of DW), caffeoylquinic acid (0.180 \u00b1 0.029 mg\/g of DW), procyanidins (0.255 \u00b1 0.016 mg\/g of DW) and quercetin derivatives (0.181 \u00b1 0.004 mg\/g of DW). Both temperature and tangential speed affect the amount of phenolic compounds in fruit juices, highlighting the need to control the technological process to obtain a more nutritious\/healthier beverage. Overall, NFC juices arise as a better option when compared with concentrated juices. Furthermore, the higher yield of phenolic compounds found in fruit pomace clearly open new ways for upcycling this fruit by-product as a high-value-added ingredient.<\/jats:p>","DOI":"10.3390\/plants12193397","type":"journal-article","created":{"date-parts":[[2023,9,26]],"date-time":"2023-09-26T08:55:01Z","timestamp":1695718501000},"page":"3397","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Characterization of the Effect of a Novel Production Technique for \u2018Not from Concentrate\u2019 Pear and Apple Juices on the Composition of Phenolic Compounds"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4802-7881","authenticated-orcid":false,"given":"Jos\u00e9 Carlos","family":"Teixeira","sequence":"first","affiliation":[{"name":"LAQV-REQUIMTE, Chemistry and Biochemistry Department, Faculty of Sciences, University of Porto, Rua do Campo Alegre 689, 4169-007 Porto, Portugal"}]},{"given":"Catarina","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Chemistry and Biochemistry Department, Faculty of Sciences, University of Porto, Rua do Campo Alegre 689, 4169-007 Porto, Portugal"}]},{"given":"Rodolfo","family":"Sim\u00f4es","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Chemistry and Biochemistry Department, Faculty of Sciences, University of Porto, Rua do Campo Alegre 689, 4169-007 Porto, Portugal"}]},{"given":"Maria Jo\u00e3o","family":"Alegria","sequence":"additional","affiliation":[{"name":"SUMOL+COMPAL Marcas S.A, Estr.
