متن کاملFurfural accumulation in stored orange juice concentrates.
The mode of furfural accumulation was determined in aseptically filled containers of single-strength orange juice and concentrates during storage at six different temperatures. Results showed that furfural accumulated in orange juice more rapidly than in concentrates of 34,44, and 58 OBrix. There was 4 times the amount of furfural in orange juice (12 "Brix) than in concentrate (58 "Brix) stored...

متن کاملIdentification of (poly)phenolic compounds in concord grape juice and their metabolites in human plasma and urine after juice consumption.
Analysis of Concord grape juice by HPLC with ESI-MS(n), PDA, and fluorescence detection resulted in the identification and quantification of 60 flavonoids and related phenolic compounds, which were present at an overall concentration of 1508 ± 31 μmol/L. A total of 25 anthocyanins were detected, which were mono- and di-O-glucosides, O-acetylglucosides, O-p-coumaroyl-O-diglucosides, and O-p-coum...
