This study investigated the effects of ethyl maltol and carbonation on cold-pressed Venus (new Arkansas seedless grape release, 60% Vitis vinifera L. x 40% Vitis labrusca L.) and Concord (Vitis labrusca L.) grape juices and their grape-apple blends. Sensory analysis indicated Venus juice rated higher than Concord in flavor and aroma after two months of storage at 37°C. Sensory and laboratory an...

The objective of this study was to examine serum concentrations of alpha-carotene, beta-carotene, lutein, lycopene, and beta-cryptoxanthin due to consumption of vegetable juice versus raw or cooked vegetables. Subjects included female breast cancer patients who had undergone surgical resection and who were enrolled in a feasibility study for a trial examining the influence of diet on breast can...

Unpasteurized fruit juice has been implicated in outbreaks of Escherichia coli O157:H7 (E. coli O157:H7). Meanwhile, certain fruit, such as pomegranate, contains antimicrobial components. The objective of this study was to investigate the survival and growth characteristics of E. coli O157:H7 on pomegranate juice in laboratory medium and in pomegranate-carrot and pomegranate-apple blend juices ...

Epidemiological evidence strongly suggests that fruit consumption promotes many health benefits. Despite the general consensus that fruit and juice are nutritionally similar, epidemiological results for juice consumption are conflicting. Our objective was to use DNA methylation marks to characterize fruit and juice epigenetic signatures within PBMCs and identify shared and independent signature...

From 1995 to 1998, more than 90 percent of mid-range IPOs were charged underwriter fees, or spreads, of exactly seven percent, even though evidence suggests that economies of scale in the size of the offering should allow for lower fees. Chen and Ritter (2000) offer collusion as a possible explanation based on empirical analysis and observation. Alternatively, we investigate whether the spreads...

Commercial pectolytic enzymes were investigated for their influence on phenolics and antioxidant activities of asparagus juice. The antioxidant activity of asparagus juice was analyzed according to 2,2'-diphenyl-l-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) methods. The enzymes, with the exception of pectinase from Rhizopus sp., contained rutinase, which hydrolyzed ...

Current practice is to install clear juice heaters ahead of first effect evaporators to ensure that the juice entering the evaporator is above its boiling temperature, allowing flashing to occur on entry. The alternative, of allowing the juice heating to take place in the evaporator, is sometimes rejected on the basis that heating transfer performance of an evaporator is very poor when operatin...

A centrifugal clarifier based on the principles of a hydrocyclone with an impeller was developed for centrifugal clarification of sugarcane juice, for improvement in the quality of jaggery and khandsari. The developed clarifier and an existing standard sedimentation disc centrifuge were tested in regards of effect of operational parameters, namely, settling, boiling, clarificant addition and sa...

The effect of grapefruit juice and liqorice juice on salivary pharmacokinetics of paracetamol (acetaminophen, APAP) in 8 healthy subjects (4 males and 4 females) was investigated. Paracetamol tablet (500 mg) was administered to the volunteers with either 240 mL grapefruit juice, licorice juice or water followed by saliva samples collection at different time intervals in a sequential study desig...

In this study, we investigated whether components of pomegranate could inhibit CYP3A-mediated drug metabolism. The ability of pomegranate to inhibit the carbamazepine 10,11-epoxidase activity of CYP3A was examined using human liver microsomes, and pomegranate juice was shown to be a potent inhibitor of human CYP3A. Addition of 25 microl (5.0% v/v) of pomegranate juice resulted in almost complet...
