Abstract
A method for reducing zearalenone to zearalanol, particularly to a mixture of high and low melting point zearanol distereoisomers characterized by the fact that it consists in producing the catalytic reduction of zearalenone with hydrogen, under reduction conditions, in the presence of amounts of a weak acid producing zearalanol and catalytic amounts of a platinum-based catalyst, the weak acid having a first acid ionization constant between 1 x 10-4 and 5 x 10-1, in aqueous solution and without Said weak acid is reduced to a weaker acid under the reduction conditions.
