Wagner, Annette; Dussling, Stefan; Scansani, Stefano; Bach, Peter; Ludwig, Michael; Steingass, Christof B.; Will, Frank; Schweiggert, Ralf published the artcile< Comparative Evaluation of Juices from Red-Fleshed Apples after Production with Different Dejuicing Systems and Subsequent Storage>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is ascorbic acid anthocyanin polyphenol red fleshed apple juice storage; UHPLC-DAD-ESI-QTOF-HR-MS/MS; red-fleshed ‘Weirouge’ apples; reductive juice processing; spiral filter press; vacuum dejuicing.
In this work, two vintages (2019 and 2020) of red-fleshed ′Weirouge′ apples were processed with the innovative spiral filter press technol. to investigate juice production in an oxygen-reduced atm. After pressing, a more brilliant red color and appreciably higher amounts of oxidation-sensitive constituents (ascorbic acid, anthocyanins, and colorless (poly)phenols) were seen in spiral filter pressed juices compared to those produced with conventional systems (horizontal filter press and decanter). In a subsequent stability study (24 wk storage at 4, 20, and 37 °C), the color and phenolic compounds were monitored and differences in the juices produced with the different pressing-systems were widely maintained during the storage period. The analyses of the anthocyanins and colorless (poly)phenols were conducted by UHPLC-DAD-ESI-QTOF-HR-MS/MS and UHPLC-DAD. The spiral filter press emerged as a promising technol. for the production of juices with a more attractive color and a better retention of oxidation-sensitive constituents during processing and storage compared to conventional juices.
