Citrinin h1

WebFeb 19, 2024 · The citrinin toxicity depends on its concentration and probably also on pH of the medium that affects the activity and bioavailability [12, 13]. Citrinin is rather heat-stable and decomposes at a temperature above 175 °C. In presence of water, it is degraded to citrinin H1, a conjugate of two molecules, that also exhibits high toxicity . WebDec 14, 2024 · Citrinin H1, a highly toxic compound formed from citrinin degradation, was found after heating at 140 °C with the presence of water or at 100 °C for 30 min (Trivedi et al. 1993a, b). Shu and Lin ( 2002 ) found that citrinin concentration in angkak was dramatically decreased after boiling in water, while Hirota et al. ( 2002 ) stated that ...
