Carotenoid and phenolic profile of tomato juices processed by high intensity pulsed electric fields compared with conventional thermal treatments
(Elsevier, 2009)The effect of high intensity pulsed electric fields (HIPEF) processing (35 kV/cm for 1500 ls of overall treatment time with bipolar pulses of 4-ls at 100 Hz) and heat pasteurisation (90 C for 30 s or 60 s) on carotenoids ... -
Cell wall metabolism in cold-stored 'Somerset' sweet cherry fruit
(International Society for Horticultural Science (ISHS), 2017)'Somerset' is a dark-red, sweet cherry (Prunus avium L.) cultivar displaying remarkable firmness levels, with concomitantly longer shelf-life potential in comparison to other varieties. It is generally accepted that fruit ... -
Changes in bioactive composition of fresh-cut strawberries stored under superatmospheric oxygen, low-oxygen or passive atmospheres
(Elsevier, 2010)The effect of different modified atmosphere packaging conditions (2.5 kPa O2 + 7 kPa CO2, 10 kPa O2 + 5 kPa CO2, 21 kPa O2, 60 kPa O2 and 80 kPa O2) on the antioxidant properties of fresh-cut strawberries was investigated. ... -
Changes in bioactive compounds concentration and physicochemical properties of mango smoothies treated by ultrasound
(Academia Mexicana de Investigación y Docencia en Ingeniería Química, A.C., 2018)Mango smoothies prepared with whole milk (WM-MS) or soymilk (SM-MS) were processed by ultrasound (400 W, 24 kHz, 100 µm amplitude for 20 min at 35 and 55 °C) in order to evaluate the effects on physicochemical parameters ... -
Changes in biosynthesis of aroma volatile compounds during on-tree maturation of ‘Pink Lady®’ apples
(Elsevier, 2008)The production of aroma volatile compounds and standard quality attributes, in addition to lipoxygenase (LOX), hydroperoxide lyase (HPL), pyruvate decarboxylase (PDC), alcohol dehydrogenase (ADH) and alcohol o-acyltransferase ... -
Changes in quality and maturity of ‘Duke’ and ‘Brigitta’ blueberries during fruit development: postharvest implications
(International Society for Horticultural Science (ISHS), 2018)Fresh Chilean blueberries take in average 20-50 days to reach overseas markets, so a better knowledge of their postharvest behavior would help maintaining their quality for longer periods. Quality of highbush blueberries ... -
