this study was designed to investigate the effects of tangerine, orange, and grapefruit juice on the pharmacokinetic pattern of cyclosporine a in rats. forty male sprague-dawley rats were divided into four groups to receive water, orange, tangerine, or grapefruit juices respectively. water or juices (10 ml/kg) were given orally twice a day for 3 days. three hours after the 5 th dose, cyclospori...

There have been very limited reports on the effects of commercial fruit juices on human CYP3A activity. Therefore, the inhibitory effects of readily available commercial fruit juices on midazolam 1'-hydroxylase activity, a marker of CYP3A, were evaluated in pooled human liver microsomes. The fruit juices investigated were black raspberry, black mulberry, plum, and wild grape. White grapefruit, ...

Sugar juices in the production of beet sugar contain complex varieties of colored materials that have not been identified completely. Color of the sugar depends the color of juices from which sugar is produced. The mechanisms concerning color formation in beet sugar processing are complicated due to many parameters involved. The main mechanisms related to the color formation during purification...

This study investigated the effects of high hydrostatic pressure (HHP) at 400-600 MPa/25 and 50°C/20 min on physicochemical qualities and bioactive compounds retention in Yanang juice mixed with 10% (v/v) longan flower-honey. The results showed that the parameter (brightness) significantly increased in pressurized juices when compared to fresh juice, while the greenness (-a*) of all processed j...

Commercial juices of sweet pomegranates and fresh juices of sour-sweet pomegranates were analysed for organic acids, sugars, antioxidant activity, volatile composition, sensory profile and consumer liking. Organic acids and sugars were analysed by HPLC, while volatiles were extracted using hydrodistillation and analysed by GC-MS and GC-FID. Malic acid was predominant in sweet juices while citri...

Grape juices are an important source of food antioxidants. Unfortunately, there is little data about the mineral composition and the antioxidant, mutagenic and antimutagenic activities of grape juice in eukaryote cells. We evaluated the mineral contents (Mg, Ca, Mn, Fe, Cu, Zn, Si, S, Cl) of grape juices, the antioxidant, mutagenic and/or antimutagenic activities of the juices in the yeas...

Subjects rated their liking for (Experiment 1) and their preferences between (Experiment 2) weakly hedonically positive test paintings. Some subjects first saw and rated some hedonically negative context paintings. Those subjects reported greater liking for (Experiment 1) and larger preferences between (Experiment 2) the test paintings than did subjects who saw and rated only the test paintings...

dicated that the developed flavor descriptive analysis procedure can be used either in Spain or USA with similar outcomes. Orange juices prepared using similar processes in both countries had comparable flavor characteristics. Thus, hand-squeezed orange juices were described with citrus fruits, green and floral attributes. Pasteurized products were also described as citrusy, green and sweet fru...

The purpose of this study was to analyze polyphenol rich beverages (vitamin enhanced waters (VEWs), fruit juices and berry juices) to determine free polyphenol concentrations and free polyphenols per Calorie based on a serving size. The Folin-Ciocalteu reagent was used in a colorimetric assay based on a catechin standard. Fruit and berry juices contained, on average, more than eight-times the c...
