Purge-and-trap, solid-phase extraction, and solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) sample preparation techniques for the analysis of odor impact chemicals in fermented cucumber brine are compared. SPME-GC-MS is coupled with detection frequency olfactometry experiments to determine key impact odor compounds in the brine. The most potent odorants that define...

Introduction: Diazinon is a moderately toxic broad-spectrum organophosphate, with a LD50 of 350 to 400 mg/kg for humans. Diazinon is absorbed through the skin and gastrointestinal tract and is rapidly metabolized within a few hours. Diazinon residues in melons and cucumbers have recently became a major health concern in Iran. Thus we decided to investigate Diazinon levels in melon and cucumbe...

The addition of various amounts of acetic acid to pureed cucumbers inoculated with Clostridium botulinum spores has shown that outgrowth is inhibited at pH 4.8 but not at pH 5.0. Inoculation experiments with whole cucumbers showed that as little as 0.9% acetic acid in the brine was sufficient to prevent outgrowth from spore inocula as high as 10(6)/cucumber. It was further shown that the rapid ...

Schultz, B., Phillips, C., Rosset, P. and Vandermeer, J., 1982. An experiment in intercropping cucumbers and tomatoes in southern Michigan, U.S.A. Scientia Hortic., 18: 1--8. Yields are reported for an experimental intercrop of tomatoes and cucumbers in southeastern Michigan, U.S.A., during the 1980 growing-season. The land equivalent ratio (LER) was 1.14, that is, 14% more land would be needed...

Objective: This study was conducted to assess the toxicity profile of the aqueous-fermented extract of Musa paradisiaca in rats. Materials and Methods: In acute toxicity test, the rats of different groups were orally administered with a single dose of 500, 1000, 2000 and 5000 mg/kg of fermented extract of M. paradisiaca. The rats were monitored for behavioral changes, toxicity signs and mortali...

BACKGROUND Allergic reactions after ingestion of fermented soybeans have rarely been reported. Fermented soybeans were recently reported to be a causative food of IgE-mediated, late-onset anaphylaxis without early phase responses. The objectives of our study are to clarify the clinical and laboratory features and to characterize the allergens in allergy due to fermented soybeans. METHODS Seve...
