The influence of four day/night growing temperature combinations (18/12, 25/12, 25/22, 30/22 C) on phenolic acid, flavonol, and anthocyanin content and their antioxidant activities against peroxyl radicals (ROO ), superoxide radicals (O2 ), hydrogen peroxide (H2O2), hydroxyl radicals (OH ), and singlet oxygen (O2,) in fruit juice of ‘Earliglow’ and ‘Kent’ strawberry (Fragaria x ananassa Duch.) ...

the nylon and nylon/lycra yarns were coated with electrically conductive polymers such as polyaniline and polypyrrole, via chemical polymerization process. electrical conductivity of the coated yarns was measured at variousstrain levels using two-point probe technique and their strain sensitivities were studied. the results showed that, electrical conductivity of the coated yarns decreased with...

The concentration of nitrate and nitrite in fruit juice products varies depending on their origin, storage condition and processing technologies .The objectives of this study were: To determine the concentration of nitrate and nitrite levels in most known fruit juices available commercially in the form of packaged in Tehran market (Iran), by spectrophotometric methods, and to compare these resu...

Tropical fruits like pineapple, papaya, mango, and beverages such as green or black teas, represent an underestimated source of antioxidants that could exert health-promoting properties. Most food processing technologies applied to fruit beverages or teas result in an impairment of inherent nutritional properties. Conversely, we hypothesise that lactic acid fermentation may constitute a promisi...

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...

a major portion of the iranian fig (ficus carica) industry is located in high-salinity regions, and salinity is an important limiting factor in the production of this fruit. the present study was conducted to investigate the changes of leaf antioxidant-enzyme activity, proline and total protein content in two fig cultivars with two leaf shapes: ‘anjir sabz’ with lobate and palmate leaves, and ‘...
