Modulation of drug transport by citrus fruit juices
… have been variously studied with citrus fruit juices. The collective data led us to hypothesize that the modulating activity of citrus fruit juices on cellular transport and metabolic pathways is dependent on the dominant flavonoid pattern and taxonomy of the citrus fruits. Grapefruit and …

Determination of phytochemicals in vegetable juices and their effects on postprandial glycaemia
… content of 23 commercially available vegetable juices which are available on the UK market, utilising 6 biochemical assays, before and after in vitro digestion. Beetroot juice had the highest total antioxidant capacity and total polyphenol content regardless of the method of analysis, and both …

The prevention of spoilage in fruit juices by alicyclobacillus acidoterrestris and propionibacterium cyclohexanicum
… bacterium was investigated in different fruit juices, when challenged by the preservatives sodium benzoate and potassium sorbate and the bacteriocin nisin and when grown in the same juice container and co-cultured on the same solid medium. 17% of samples tested were contaminated by A. …

An integrated risk assessment of patulin in apple juices throughout the food chain
De beschikbaarheid van veilig voedsel is een essentiële voorwaarde voor het menselijk bestaan. Eén van de gevaren die in onze voeding voorkomen is patuline. Dit mycotoxine wordt voornamelijk gevormd door de schimmel Penicillium expansum, die frequent wordt teruggevonden op appels. Appels en …

Survival of Listeria monocytogenes in Fruit Juices During Refrigerated and Temperature-Abusive Storage
… used to inoculate (approx. 7 log cfu/ml) fruit juices, which were stored at 4, 10 and 24°C for up to 61 days. Inoculated red grape juice was stored for up to 5 hours only. Samples were withdrawn at appropriate intervals, neutralized with 1.0 N NaOH, serially diluted in 0.1% peptone water, and …

The Efficacy of Antimicrobials for the Control of Alicyclobacillus acidoterrestris in Fruit and Vegetable Juices
… for control of A. acidoterrestris spoilage in juices was analyzed. Apple and tomato juices were inoculated with 4 log spores/ml. Antimicrobials were added at: 1000, 500 and 250 ppm (sodium benzoate, potassium sorbate, and sodium metabisulfite); 500, 250, and 125 ppm (cinnamic acid, dimethyl …

Evaluation of chemical treatments and ozone on the viability of Cryptosporidium parvum oocysts in fruit juices
… <i>C. parvum</i> oocyst viability in fruit juices. Oocyst viability was analyzed with a cell culture infectivity assay, using a human illeocecal cell line (HCT-8) that is most similar to human infection. The percent inhibition of infection by each treatment was determined along with the …

Effect of cinnamic acid-cyclodextrin inclusion complexes on populations of Escherichia coli O157:H7 and Salmonella enterica in fruit juices
… could be used to control bacterial pathogens in juices. Based upon phase solubility analysis, α-cyclodextrin was chosen as the host molecule for the remainder of this study. In complex with α-cyclodextrin, the solubility of cinnamic acid increased from approximately 400 mg/L to 3800 mg/L. …

Oxalate content of green juices and strategies for reduction of soluble oxalate content : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
Green juices are an example of a modern food innovation that has developed partly by itself in response to general nutritional advice in the media imploring people to consume more fruits and vegetables. Unfortunately, the risks of developing acute oxalate nephropathy is high following the …

Antibacterial Activity of Hydrogen Peroxide Against Escherichia Coli O157:H7 and Salmonella Spp. in Fruit Juices, Both Alone and in Combination With Organic Acids
… of hydrogen peroxide treatments in four fruit juices was determined. Preservative free apple cider, white grape, and purple grape juice were inoculated with ~ 6.4 log CFU/ml of a five strain, acid adapted, nalidixic acid resistant E. coli O157:H7 cocktail. Orange juice was inoculated with a …

Rapid Assessment of Quality Parameters in Processing Tomatoes using Handheld and Bench-top Infrared Spectrometers and Multivariate Analysis
… in processing tomatoes. A total of 370 hot-break juices were prepared from ~40 processing tomato varieties grown in 5 California counties. The levels of sugars (glucose and fructose), acids (citric, malic, and glutamic), soluble solids, titratable acidity, and pH in these juices were determined …

The potential of sorghum as a feedstock source for bioethanol production in Nigeria
… can be utilised as a brewing adjunct. The stalk juices are used in syrup production while the green field residues (bagasse) are partly used in forage production and fencing but mostly left in field for burning. This thesis has shown that sorghum crops have alternative uses in liquid biofuel …

Consumer perception and behaviour towards tropical fruits in Belgium
… for purchase and consumption. Tropical fruit juices are considered intrinsically healthy. Additional information about health-related benefits through the use of claims is not seen as a persuasive tool for their purchase. Nevertheless, claims seem to influence consumers’ behaviour, …

Matrix-assisted concentration and microencapsulation of lime juice
… method used in the food industry to dry fruit juices and obtain powders. Spray drying yields free flowing powders; however, it does not maintain the original flavor. Thus, the goal of this work was to develop a process to render lime juice as a free flowing dry product with an authentic fruit …

Preparation of juice concentrates by nonthermal processing technologies: a multiple hurdle approach
… study, our objectives were to concentrate fruit juices using FO or a combination of RO and FO and to explore another nonthermal technology that could potentially extend the shelf-life of the concentrate.This work successfully demonstrated the use of FO and combined RO and FO in concentrating …
