A method of treating aldehyde-tanned biological tissue minimizes in vivo calcifi cation and reduces cytotoxicity without impairing the mechanical strength of the tanned tissue. The method includes the step of treating the aldehyde-tanned biological tissue with at least one liquid polyol having formula (I), where R is CH2OH or a n alkyl group, and R' is H, an alkyl group or an O-acyl where the acyl is C2-C9 or a carboxyalkyl; or formula (II) where R is H o r an alkyl group, and R' is H, an alkyl group, O-alkyl or O-carboxyalkyl. Preferred polyols are propylene glycol, 1,3-pr opanediol, 2,3-butylene glycol and glycerol, and the polyol is preferably a diol. |
