In general, treatment with silica gel removed the largest number of amino acids from the must, although this effect was more noticeable in the case of macerated musts. On the other hand, wines obtained from musts clarified with enzymes had the highest concentrations in most of the amino acids studied, independently of whether the musts were macerated or not.
