Production of Alternaria Toxins in Yellow Peach (Amygdalus persica) upon Artificial Inoculation with Alternaria alternate

chromatography-tandem mass spectrometry (UHPLC- MS / MS). The results showed that the growth of A. alternate and the AT s production were dramatically affected by the storage temperature. At 28 °C, the fungi grew rapidly ...

Influence of reduced levels or suppression of sodium nitrite on the outgrowth and toxinogenesis of psychrotrophic Clostridium botulinum Group II type B in cooked ham.

foreseeable conditions of use and storage i.e. for 14 days at 4 °C, followed by a cold chain break for 1 h at 20 °C then up to 33 days at 8 °C. Storage times and temperatures were used to mimic those commonly ...
