Abstract: The fermentation kinetics at a constant temperature and antioxidant activity of cactus wine produced from cactus juice using SY-type Angel-branded yeast were studied. Yeast count, alcohol content, and reducing sugar in cactus wine were determined after every 12 h, and the experimental data were nonlinearly fitted to the Logistic, SGompertz and DoseResp models. Meanwhile, changes in the contents of total phenol and flavonoids and antioxidant activity of the wine were investigated as a function of fermentation time. The experimental results showed that the fitness of all the three models was confirmed by a satisfactory value of determination coefficient, which was calculated to be greater than 0.99. In addition, it was also shown that the contents of total phenol and flavonoids were relatively high in cactus wine. Cactus wine exhibited remarkable free radical scavenging activities against 1,1-diphenyl-2-picrylhydrazyl and 2,2’-azinobis-(3-ethylbenzthiazoline- 6-sulphonate and potent Fe3+ reduction power.
