Agaritine, a genuine toxin of A. bisporus, is degraded by heating or freezing. Ostreolysin A is a toxic cytolysin of P. ostreatus that perforates membranes of erythrocytes, thus resulting in a non-selective permeability towards ions and small neutral solutes [ 95 ].Agaritine levels in brine were generally slightly lower than the levels detected in canned mushrooms. Thus, the level of agaritine in A. bisporus is reduced more than 10 times during the wet canning process, resulting in low levels in canned products. On a portion basis, somewhat higher amounts of agaritine may be found in some other food ...N-nitrosation followed by nitroso-reduction is also suspected in the case of agaritine and agaritinal, hydrazide derivatives produced by the mushroom Agaricus campestris (Scheme 5). 28 These compounds were isolated together with their suspected precursor p-hydrazinobenzoic acid.This latter may derive from p-aminobenzoic acid …Agaritine in cultivated Agaricus bisporus has been reported in some animal model studies to be associated with potential carcinogenic effects, although this has been challenged by others and contradicted by other studies in …
