| heal.abstract | Sulphur dioxide and mixtures of glutathione with caffeic acid or gallic acid were tested as inhibitors of the decrease of isoamyl acetate, ethyl hexanoate and linalool during storage of a model wine medium. Model wine samples were analysed by SPME and GC-MS. Isoamyl acetate, ethyl hexanoate and linalool decreased during storage of the model wine medium containing 0, 20, 40 or 60 mg/l free SO2. SO2 protected the three volatiles at 20 (isoamyl acetate), 40 (ethyl hexanoate) and 60 mg/l (linalool). Mixtures of glutathione with caffeic acid or gallic acid were also protective; they were more active at 10 + 30 mg/l than at 5 + 15 mg/l. Glutathione + caffeic acid was more effective than glutathione + gallic acid. In most cases, SO2 at 40 mg/l increased the protective effect of the mixtures. SO2 at 60 mg/l exhibited protective ability comparable to that of glutathione + gallic acid 5 + 15 mg/l. The present results indicate that SO2 protects some wine aroma volatiles, but at high concentrations. On the other hand, mixtures of the wine constituents glutathione + caffeic acid or gallic acid are more effective at concentrations similar to those existing in wines.
