Abstract The low-salt process was used for dry-salted bacon processing, and changes in bacon weight, pH value, peroxide value, volatile components and color were analyzed during the process. The influence of sage added into the bacon on peroxide value was studied as well. The weight loss was bigger after 7 days of salting, and then significantly decreased with prolonged salting time. The pH, within the range of 5.3 to 5.5 and similar to that of the corresponding fresh meat, had no significant change during the whole process. As the process proceeded, the peroxide value showed a gradual increase, but the increase was markedly inhibited by sage addition, suggesting sage to be very effective against fat oxidation. In addition, sage addition exerted a significant effect on the main volatile flavor components of dry-salted bacon. Considerable changes in color parameters L*, a* and b* were also observed. The composition and contents of volatile components strikingly differed between products with and without the addition of sage.
