An APCOR project to identify a process to eliminate the contamination of cork by haloanisols (which cause cork taint) and their chemical precursors (halophenols) in cork. The work had two goals: development of biotechnological strategies based on the use of micro-organisms or their enzymes with capacity to break down chloroanisols and the analysis of the dynamics of transfer of chloroanisols from contaminated wine to cork stoppers. This work was conducted by the Institute of Biotechnology of León (Inbiotec), in Spain. The investment was around 300,000 thousand euros. The research resulted in a book, “Wine Contamination by haloanisols”, published in Portuguese and English (cap1, cap2, cap3, cap4).
