Exposure of Escherichia coli O157:H7 to chlorine before heat treatment results in increased production of heat shock proteins. Current heating regimens for pasteurizing apple cider do not account for chlorine exposure in the wash water. This research determined the effect of sublethal chlorine treatment on thermal inactivation of E. coli O157:H7. D58-values were calculated for stationary-phase ...

Shigella flexneri, Salmonella enterica serotype Typhimurium, and Listeria monocytogenes were applied to FTA filters, and the filters were used directly as templates to demonstrate their sensitivity and applicability in PCR-based detection assays. With pure cultures, the sensitivities of detection by FTA filter-based PCR were 30 to 50 and 200 CFU for the gram-negative enterics and Listeria, resp...

Results of 3 experiments showed that infant rats (age 13-17 days) generalize conditioned taste aversions between alcohol and non-alcohol tastes such as a mixture of sucrose and quinine, apple cider vinegar, or coffee. Nonreinforced preexposure to those tastes reduced generalized aversions between them. Generalization between alcohol and sucrose-quinine was reduced not only after preexposure to ...

Color and volatile stimulus preferences of Drosophila repleta (Patterson) Diptera: Drosophilidae), a nuisance pest of swine and poultry facilities, were tested using sticky card and bottle traps. Attractions to red, yellow, blue, orange, green, purple, black, grey and a white-on-black contrast treatment were tested in the laboratory. Drosophila repleta preferred red over yellow and white but no...

Apple is one of the delicious fruit consumed by people. cider vinegar was made through traditional method and changes occurred during 8 week fermentation period were determined in this research. Total titratable acidity, pH, total soluble solids (°brix), phenolic contents, Oxygen Radical Absorbance Capacity (ORAC) Trolox Equivalent Antioxidant (TEAC) assays, contents determined. substance, ORAC...

Patulin is a toxic chemical contaminant produced by several species of mold, especially within Aspergillus, Penicillium and Byssochlamys. It is the most common mycotoxin found in apples and apple-derived products such as juice, cider, compotes and other food intended for young children. Exposure to this mycotoxin is associated with immunological, neurological and gastrointestinal outcomes. Asse...
