VOLDŘICH M., SKÁLOVÁ P., KVASNIČKA F., CUHRA P., KUBÍK M., PYŠ P. (2002): Authenticity of 100% orange juice in the Czech market in 1996–2001. Czech J. Food Sci., 20: 83–88. Commercial orange juices samples obtained from the Czech market were analysed in the years 1996–2001. The quality and authenticity of samples was evaluated according to the Code of Practice of AIJN (selected main analytical ...
We studied the effects of cooking on the vitamin and mineral content of vegetables (vegetable soup, cauliflower), meat (beefsteak) and fish (sole) and those of cutting (fruit salad) and squeezing (orange juice) on the vitamin content of fruits. In cooked dishes, vitamin retention ranged between 0 (folic acid, all dishes) and 94% (retinol, sole) and mineral retention between 63 (copper, cauliflo...
Oranges are rich sources of flavonoids that are bioactive and may protect against age-related diseases. The absorption of orange flavanones may be affected by factors such as processing and subject anthropometric variables, and the bioactivity of the absorbed phytochemicals depends on how they are metabolised during absorption. In a randomised cross-over study, twenty subjects consumed a single...
BACKGROUND Citrus sinensis juice (CSJ) is a rich source of dietary flavonoids which reduce the risk of adverse cardiovascular events. This study aimed to examine the effects of four-week intake of natural and commercial orange (Citrus sinensis) juice on blood pressure in healthy volunteers. METHODS In this single-blind randomized crossover study, 22 healthy subjects (age: 18-59 years old) wer...
A technique for the analysis of multivariate data by genetic programming (GP) is described, with particular reference to the quantitative analysis of orange juice adulteration data collected by pyrolysis mass spectrometry (PyMS). The dimensionality of the input space was reduced by ranking variables according to product moment correlation or mutual information with the outputs. The GP technique...
'I'he shelf life of fruit juices and concentrates is limited primarily by microbial, enzymatic, and chemical reactions that adversely affect their nutritional quality, color, and flavor. Pasteurization requirements of freshly extracted citrus juices are based on inactivation of thermally resistant endogenous enzymes whereas requirements for reconstituted juices are based on destruction of micro...
An extruded composite food packaging film containing pectin, polylactic acids (PLAs) and nisin was developed to inhibit Listeria monocytogenes. The mechanical properties and surface structure of the film were also examined. Cells of L. monocytogenes were reduced by 2.1, 4.5 and 3.7 log units mL by the pectin plus PLA (pectin ⁄PLA) film containing nisin (1000 IU mL of tested liquid) in Brain Hea...
The overwintering survival and development of Drosophila suzukii Matsumura were investigated in California's San Joaquin Valley. Drosophila suzukii were exposed to overwintering conditions in cages hung in a citrus orchard, and the pupae were buried in the soil. Eggs exposed from late November to January did not survive; a low percentage (<3%) of larvae and pupae developed into adults. Survival...
