Pathogenic Escherichia coli O157:H7, as well as nonpathogenic strains ATCC 11775 and ATCC 23716, grew exponentially in wounds on Golden Delicious apple fruit. The exponential growth occurred over a longer time period on fruit inoculated with a lower concentration of the bacterium than on fruit inoculated with a higher concentration. The bacterium reached the maximum population supported in the ...

BACKGROUND Campylobacter jejuni is a common cause of human bacterial diarrhea in most parts of the world. Most C. jejuni infections are acquired from contaminated poultry, milk, and water. Due to health care costs and human suffering, it is important to identify all possible sources of infection. Unpasteurized milk has been associated with several outbreaks of C. jejuni infection. Campylobacter...

The term “mycotoxin” is generally associated with secondary metabolic toxic products of filamentous fungi to which humans and animals can be exposed, most often through ingestion. This exposure can result in a range of toxicities (acute to chronic), and a spectrum of effects (mild to severe) including carcinogenicity and death. The history of mycotoxicoses has been long and dramatic, including ...

Until recently, acidic products such as fruit juice and fruit based products were generally thought to be susceptible to spoilage by yeasts, mycelia fungi and lactic acid bacteria, as the low pH of these products acts as natural control measures against spoilage by most bacteria. Alicyclobacillus seem to be prevalent in fruit based products as they survive the acidic fruit juice environment, ev...

A mild water stress was imposed upon potted tangerine trees (Citrus sinensis Blanco. cv. Zhuju) by water withholding during early juice sac expansion stage. While fruit growth was inhibited by water stress a growth potential was built up inside the fruit, which was not expressed until rewatering. The more powerful water uptake force of the stressed fruit was caused by its more negative fruit wa...

Blackberry (Rubus fruticosus spp.) fruit has high antioxidant activity due to its significant content of anthocyanins and antioxidant compounds. Among emerging technologies for food preservation, thermoultrasound is a technique that reduces microbial loads and releases compounds with antioxidant properties. The objective of this study was to determine the antioxidant content and fatty acid prof...

OBJECTIVE We compared elementary students' school lunches selected and consumed before (Spring, 2011) and after (Spring, 2013) implementation of the new National School Lunch Program meal patterns in the fall of 2012. METHOD Students in eight elementary schools in one Southeast Texas school district were observed during lunch: foods selected/consumed were recorded. The percentage of students ...

The aim of this study was to investigate the protective effects of juice powders from sweet orange [Citrus sinensis (L.) Osbeck], unshiu mikan (Citrus unshiu Marcow), and mini tomato (Solanum lycopersicum L.), and their major flavonoids, hesperidin, narirutin, and rutin in tert-butyl hydroperoxide (t-BHP)-induced oxidative stress in HepG2 cells. The increased reactive oxygen species and decreas...

Pomegranate juice is in high demand due to its well documented health benefits. Studies based on a significant body of scientific research conducted on authentic pomegranate juice have established that pomegranate juice has superior antioxidant activity compared to other popular fruit juices such as grape, orange and apple1,2,3. These superior health benefits have led to a meteoric rise in the ...
