WebMay 15, 2024 · Citrinin H1 and H2 are degradation products of citrinin that are formed by boiling citrinin solution. Approximately 5 µL of degraded citrinin solution (10 pmol/µl) was required for visual detection of citrinin with our minimum recommended amount as opposed to only 1 µL untreated citrinin solution (10 pmol/µl) ( Fig. S8 , SI). WebApr 8, 2024 · Citrinin can be transformed into more complex compounds during food processing, such as citrinin H1 and citrinin H2. Two citrinin molecules combine to form citrinin H1, which is more toxic than citrinin (Koppen et al. 2010). So far, no specific regulations exist for this mycotoxin, but it is fixed to 2000 μg/kg for fermented rice foods.
