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 bioactive compounds content and antioxidant capacity of pecan nuts [Carya illinoinensis (Wangenh. K. Koch)] during storage
(Academia Mexicana de Investigación y Docencia en Ingeniería Química, 2020)Pecan nut kernels are rich in health-promoting substances such as unsaturated fatty acids, tocopherols, and phenolic compounds. Due to their importance in the human diet, it is essential to evaluate the effects of drying, ... -
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 ... -
Changes in the quality and antioxidant properties of fresh-cut melontreated with the biopreservative culture Pseudomonas graminis CPA-7 during refrigerated storage
(Elsevier B.V., 2016)The strain CPA-7 of Pseudomonas graminis, isolated from apple by our group, was reported to reduce the population of foodborne pathogens in minimally processed fruit. The aim of this work was to investigate its effect on ... -
