Citrinin H2, a formylated derivative of phenol A, is less toxic than citrinin. Phenol A seems to be produced mainly under acidic conditions. Dicitrinin A is a dimer of citrinin molecules … See more Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminates long-stored food and it causes different toxic effects, like nephrotoxic, hepatotoxic and cytotoxic effects. … See more Citrinin was one of the many mycotoxins discovered by H. Raistrick and A.C. Hetherington in the 1930s. In 1941 H. Raistrick and G. Smith identified citrinin to have a broad antibacterial activity. After this discovery the interest in citrinin rose. However, in 1946 … See more The existing information on occurrence of citrinin in food suggests that relatively high citrinin concentrations can be found in stored grains and … See more Citrinin is biosynthesized by fungi species of Penicillium, Monascus and Aspergillus.
